gdb 7.12.1 on RSB 4.12 branch fail to build on Archlinux

Description

7.12.1 does not compile with latest guile As already stated here: https://sourceware.org/bugzilla/show_bug.cgi?id=21104 GDB in version 7.12.1 fails when trying to compile on Archlinux. GDB uses deprecated functions of libguile which were gone in version 2.2 of libguile. As GDB states in its configure script to support version 2.2 of libguile it fails compiling.

missing pax causes install failures

Description

I have tried to install sparc bsp=erc32 on 4 different builds. 3 failed, and 1 flawlessly installed. The others all seem to fail somewhere during make install of test suites. Each reports one missing config problem or another.

I believe the problem resulted in a missing package, pax & libbsd-dev on Ubuntu 12.04.5 LTS (GNU/Linux 3.2.0-126-virtual x86_64)

I hadn't seen this exact problem because I normally update & upgrade as soon as I get a new image. Pressed for time, I skipped it. So, I am not sure if we need to update the documentation to directly include pax, since it is directly called in configure and breaks if not present.

Add pax to this line $ sudo apt-get build-dep binutils gcc g++ gdb unzip git python2.7-dev pax

RTL Allows Unloading a Module other Modules Depend Upon (cloned)

Description

Cloned from #3195:


Consider the following example using ELF .o files from compiled source files module-0.c and module-1.c from ticket #3194:

module-0.o is loaded using dlopen() with no code or data dependencies. module-1.o is loaded using dlopen() with both code and data dependencies on module-0 which are resolved by RTL.

The RTL function dlcose() returns no error when module-0 is unloaded, when it should return an error and not unload module-0. This becomes quite dangerous because a subsequent call to module1Function1() in the currently-loaded module-1.o, which accesses shared_resource_0[ ] and calls module0Function0(), will result in an unexpected trap on qemu or the call succeeding with the correct return value on hardware when it should not.

The erroneous successful unload() of module-0 aside, it appears as though the resources are not actually deleted and I believe this ticket is related to tickets #3192 and #3194.

Architecture is sparc-leon3 using both the RTEMS 4.11.1 public release and rtems master @f043b9bd3bf25626fb1a311dd7fa041eacc68adc with rtems-source-builder @55f2d69e9b67cde23d61375fa34ef5b0f04a985d.

Execution environments are qemu-system-sparc and LEON3 UT700 hardware.

bootstrap uses non-POSIX compliant echo -e

Description

On certain shells, the "-e" option is not supported, and causes echo to output the flag along with the quoted text.

-> % sh
$ echo -e "foo bar"
-e foo bar
$

This varies by shell, and is not even consistent between sh or bash.

It was introduced while removing the make preinstall stage here, and may still work on most shells, though it didn't for me on sh on Ubuntu 16.04 LTS (4.4.0-78-generic x86_64 GNU/Linux) - as far as I can tell, this bug hasn't made it to any releases yet, so just fixing it on master should be enough.

A patch is attached.

Reference to the POSIX standard which confirms that -n is the only argument supported.

Upgrade trac to fix numerous problems.

Description

There are a ton of issues going on with trac that need to be resolved. The two major ones are:

  • The ticket commenter emails people who aren't a trac user. This may require a custom modification.
  • The always_email setting is taking things too literally and always sending emails even if it shouldn't.
  • The Git plug-in consistently spins, floods the jail with processes then the site dies.
  • Frequent, strange and random crashes.
    • This one is not a huge deal since it's just that request process users won't even notice when this happens.

Upgrading trac is a weeklong project usually I will start preparing for it and update here.

If anyone has any feature requests now is the time to do it!

Fix FlexibleAssignTo?

Description

When we first went to trac we had restrictions on the 'owner' to developers only. When track was upgraded this broke completely but all the code to handle this was already in place.

I took the time to fix it today so we have dropdowns again.

I've created this ticket to see if anyone has an issue with this should we keep it? Drop it? I know it's been years but it was our original choice.

See any ticket the 'reassign to' and on a new ticket the 'assign to' is now a dropdown. These are based on trac permissions so we can always add more if we need it but it really should be restricted to having a project member be the owner so we can ensure tickets are closed and sorted properly.

Heap extend allows discontinuous memory regions.

Description

The check in (cpukit/ChangeLog) states:

2010-06-07 Sebastian Huber <sebastian.huber@…>

  • score/src/heapextend.c: Implemented support for scattered heap areas.

The heap cannot support scattered blocks because the _Heap_Is_block_in_heap assumes the region is continuous between the first and last blocks of the heap. Making the gaps in the regions passed to the heap extend call used is questionable and makes the _Heap_Is_block_in_heap test not really perform the task it's name states. This is an issue because it is this check that determines if a heap free of NULL should proceed. This issue is covered in another PR.

I also wonder about a heap free call to an address that maps to one of the "in-use" gap regions. The previous heap code knew if an address was in the heap and therefore it was kind of safe to probe for a valid block. This assumption is now not valid.

The former heap extend code:

http://www.rtems.org/viewvc/rtems/cpukit/score/src/heapextend.c?revision=1.7&view=markup

clearly states the type of memory that can be added to an existing heap. The current code has no restrictions. The user manual is not great in this area. It would also be useful if comments are added to the heap extend code.

The heap extend code is used by the rtems_region_extend call and this call clearly states in the manual that the memory region must be continuous. If this has changed we should discuss the API change and make better note of it. I also suspect the testsuite will need additions to test any API changes.

RTEMS tar does not overwrite.

Description

A host tar by default will overwrite the contents of a directory. A sort of refresh. The RTEMS tar requires you remove the existing files rather than overwrite. This is dangerous because you have to remove files yet you do not know if the tar will be successful and moving and saving files assumes you know the contents of the tar file before hand.

Tar should be changed to overwrite and so allow files to be refreshed.

Consistence of files should be managed outside of tar via hashes or checksums.

ARM CP15 arm_cp15_set_translation_table_entries fails if TTB in read-only memory

Description

If the TTB is held in the text section and the section is set to read-only, and cached when booting no section change happen at run time because the table cannot be written too to change. The table cannot be changed unless the MMU is disabled.

I suggest the MMU be disabled, the table updated and then the MMU enabled.

Note, the issue only shows up on real hardware, qemu does not complain.

RTEMS I2C API only defines Standard-mode (Sm) speed as a default.

Description

The RTEMS I2C API as defined in cpukit/dev/include/dev/i2c/i2c.h only defines the bus speed as Standard-mode (Sm) as defined by the I2C standard. This is set as I2C_BUS_CLOCK_DEFAULT. The default speed is defined by the hardware, ie the devices connected, and not this API.

The API should define the speeds as defined in the I2C standard and there should be no default. Drivers like the Cadence driver for the Zynq should be modified to require the bus speed be provided and all future drivers need to provide the speed.

rtems-doc waf configure does not detect sphinxcontrib.bibtex status

Description

The rtems-docs requires the Sphinx contribution extension for bibtex to build.

A configure check should be added to see if the extension is installed and an error raised or the documentation conditionally built.

It is not clear to me if bibtex needs Tex Alive. Requiring Tex on all hosts to build the documentation is a regression so the extension will need to be removed or a fall back position taken where degraded quality documentation in HTML is created.

Add a top level global testsuite configuration file (.tcfg) and a 'user-input' test state.

Description

Adding a top level testsuite configuration file lets us specify tests that have a common test state across all BSPs.

Adding the test state 'user-input' clearly tags the test as needing user input and test result tools can correctly determine the test result. The current practice of passing a test needing user input is actually hiding the real result of the test.

SMP assert in _Thread_Executing in libdebugger

Description

The target code in libdebugger has support to recover from exceptions related to invalid memory accesses. GDB may request the server access memory on the target that results in an exception. The exception occurs on the server's remote connection thread and the server needs to recover and return and error to GDB.

Running the debugger01 test with an SMP build of RTEMS and libbsd for xilinx_zedboard and issuing bt in GDB results in:

*** LIBBSD DEBUGGER 1 TEST ***                                                                                                                                                                                                                                                                            [144/1950]

Setting interrupt level in the mode arg on SMP returns RTEMS_UNSATISFIED

Description

If for any reason a user sets the interrupt level in the mode on an SMP build the error RTEMS_UNSATISFIED is returned. The documentation indicates this is a lack of stack and this confusing.

The reason this happens is the SMP check for an interrupt level being set is in the score's _Thread_Initialize. I propose that and is_preemptible check be converted to an assert and checks be added to the Classic API to catch these errors and report suitable error codes.

There is no meaningful error code available without abusing an existing one so I propose adding RTEMS_INVALID_MODE.

SMP build of RTEMS Testsuite does not set CONFIGURE_MAXIMUM_PROCESSORS

Description

The default setting for CONFIGURE_MAXIMUM_PROCESSORS is 1 and this means rtems_configuration_is_smp_enabled() returns false. Only the smptests set the maximum processor count to CPU_COUNT and therefore run in SMP mode.

If SMP is not running in an SMP build when running the tests are the tests really reporting a true indication of the of the system?

I would expect we have the API tests, libtests and fstests running with SMP enabled in an SMP build.

#3268 16 months ago fixed arch/powerpc Chris Johns 15 months ago
Summary

PowerPC BSP include naming mess.

Description

The PowerPC BSP family headers need some refactoring for the RTEMS 5 release. The BSP family relies on the preinstall process to get suitable headers installed to work and removing preinstall exposes this. The specific issue appears with irq.h when building the no-preinstall branch. There is a PowerPC BSP family header and a number of BSPs also have an irq.h which overrides families header. The code has #include <bsp/irq.h> and the header used depends on the include order on the GCC command line. This is fragile for any user. These headers needs to be moved to BSP specific paths, for example #include <mvme3100/irq.h>.

mhttpd's http etag can result in invalid caching in a browser.

The mhttp's http etag uses the mtime and file length and this can cause subtle issues if a target has no RTC or it is incorrect and files are being copied without preserving the mtime or changes happen that do not change the length.

The cp and untar code do not update a file's time.

Add support for an etag callback so a user can manage the tag, ie MD5 or something similar.

rtems-test should not use the env PATH to find covoar

Description

The rtems-test command should know where covoar is when invoking it. It cannot use the environment's path. The path can contain invalid or outdated versions with subtle issues that could be hard to find.

There should be no need to run install to use and test rtems-test with coverage.

The rtems-test python code for running the tests knows where it is and adjusts. For example using an absolute path to rtems-tests in a build directly results in it being able to find the development tree rtemstoolkit and configuration data. The command needs to be taught to find the development version of covoar.

Note, currently covoar needs external tools and this is currently using the environment's path however there is work underway to remove this dependence so there case does not need to be handled.

RSB and RTEMS Tools Support for python2 and python3

Description

Upstream python does not create a python command any more and creates python2 and python3. Distributions and operating systems are starting to ship without the python command.

The RSB and RTEMS Tools python commands need to be updated and tested so they run on Python2 and Python3 and support added to use the available commands.

Use a short paths for the RSB temporary build path on Windows

Description

The %{_tmproot} path is currently based on a BuildRoot setting in the build configuration files. The line is:

BuildRoot: %{_tmppath}/%{name}-root-%(%{__id_u} -n)

This is for a shared $TEMP path plus the name is not shortened so on Windowss these paths become long. Remove the BuildRoot from all configuration files and add support for a shortened temporary path. Windows needs short paths due to the 256 max. path length issue.

rtems-docs.git does not build with Sphinx 1.8.2 and 1.8.3

Description

The docs do not build with Sphinx 1.8. Recent posts indicate some changes to support unicode indexes via xindy have caused this and the solution being discussed is to use the generate Makefile ...

https://github.com/rtfd/readthedocs.org/issues/4454

The need to use the Makefile is debatable however what it contains is important as it defines what needs to happen.

This recent issue can be seen in the Tex generated file for the User Manual (user.tex). It contains:

\item[{Waf\index{Waf@\spxentry{Waf}|spxpagem}\phantomsection\label{\detokenize{glossary/index:term-waf}}}] \leavevmode
Waf build system.  For more information see \sphinxurl{http://www.waf.io/}

Our current build uses pdflatex directly and there is an error as spxpagem is not defined.

If you inspect a version 1.8 generated Makefile the command latexmk is used. This wraps the PDF generation so the correct number of passes are performed. Using this tool should be considered.

The Makefile contains:

export XINDYOPTS = -L english -C utf8  -M sphinx.xdy

The sphinx.xdy contains the needed spxpagem. I can only conclude sphinx needs to be built with xindy because the reference is always generated.

The problem for building FreeBSD is xindy is not an available command.

ARM BSP contains ARM code in THUMB only build

Description

The xilinx_zynq_a9_qemu BSP contains a memcpy that is ARM mode code and not THUMB. This can be seen with hello.exe and vlan01.exe in the libbsd examples.

The script run with the command that follows shows there is a single ARM function in the executable. The python script is:

from __future__ import print_function
import sys
for line in sys.stdin:
    ls = line.split()
    if len(ls) == 8 and ls[0][-1] == ':' and ls[3] == 'FUNC':
        addr = int(ls[1], 16)
        if addr & 1 == 0:
            print(ls[7])

Command with output:

$ arm-rtems5-readelf -a `find . -name hello.exe` | python ./arm-thumb.py
memcpy

The presence of this single function makes me wonder why and if something is wrong in the building of the memcpy function. Examination with rtems-exeinfo shows the code is built by GNU AS from the file memcpy-armv7a.S while other asm files are not generating ARM code. The section of the output from:

$ rtems-exeinfo -a `find . -name hello.exe`

is:

  GNU AS 2.31.1: 14 objects  
   | arm_exc_interrupt.S        
   | armv4-exception-default.S
   | bpabi.S        
   | bpabi.S           
   | bsp-start-memcpy.S
   | cpu_asm.S     
   | lib1funcs.S     
   | lib1funcs.S              
   | lib1funcs.S   
   | memchr.S    
   | memcpy-armv7a.S
   | start.S         
   | strcmp-armv7.S       
   | strlen-armv7.S   

GNU LD is correctly managing the interworking and the code runs however is this behavior expected and understood? Note, the existence of this code breaks libdl's loading of dhcpcd.c as section .rel.text.dhcpcd_handle_hwaddr contains a R_ARM_THM_JUMP24 relocation record which requires a veneer in large memory application as well as bl to blx support. This support could be added but I am not currently in favor of having this support for something that should not happen.

scandir() fails due to MAXNAMELEN is incorrect

Description

I have been trying to use scandir() however the newlib one does not work due to MAXNAMLEN and NAMLEN differ. scandir in libcsupport seems to have a fix for this, however my libcsupport_a-scandir.o is empty, I'm guessing because HAVE_SCANDIR is defined.

It is used in scandir() (newlib-1.17.0/newlib/libc/posix/scandir.c:117) by the macro DIRSIZ. Where DIRSIZ uses the MAXNAMELEN define which is set incorrectly. It does not match the sizeof(struct dirent) which makes the DIRSIZ return a negative number, then malloc(DIRSIZ(d)) will try to allocate 4GB which fail.

My guess is that MAXNAMELEN should be defined in newlib-1.17.0/newlib/libc/sys/rtems/sys/dirent.h or newlib-1.17.0/newlib/libc/sys/rtems/include/limits.h or in a new file.

I tried to run the code below on my FAT filesystem, taken directly from the scandir(3) man page.

/* print files in current directory in reverse order */ #include <dirent.h> main(){

struct dirent namelist; int n;

n = scandir(".", &namelist, 0, NULL); if (n < 0)

perror("scandir");

else {

while(n--) {

printf("%s\n", namelist[n]->d_name); free(namelist[n]);

} free(namelist);

}

}

Summary

Inconsistent blocking addressing in RFS

Description

Background There are two ways to address a block in RFS:

  1. Via a single 32bit block number (bno)
  2. Via a group number(gno) and a bit offset (bit)

They should be fully convertible (1-1 mapping). In other words, the equation to convert 1 to 2 should be unique within the RFS implementation.

The bug The RFS implementation contains two different conversions between 1 and 2.

Details

  1. In rtems_rfs_group_bitmap_alloc (rtems-rfs-group.c, line 172)
    bno = gno * group_blocks + bit
    
  1. In rtems_rfs_group_bitmap_alloc (rtems-rfs-group.c, line 228)
    bno = gno * group_blocks + bit + 1 (via rtems_rfs_group_block() function)
    
  1. In rtems_rfs_group_bitmap_free (rtems-rfs-group.c, line 283)
    bno = gno * group_blocks + bit + 1 (RTEMS_RFS_SUPERBLOCK_SIZE)
    
  1. In rtems_rfs_group_bitmap_test (rtems-rfs-group.c, line 332)
    bno = gno * group_blocks + bit
    

To summarize, the implementation contains two ways of converting a bno to a (gno, bit) pair:

Either:

bno = gno * group_blocks + bit

Or:

bno = gno * group_blocks + bit + 1

The Fix The RFS implementation should consistently convert a bno to a (gno, bit) pair with:

bno = gno * group_blocks + bit + RTEMS_RFS_SUPERBLOCK_SIZE

This is because the superblock is not accounted for in the block bitmaps. So places to change:

  1. rtems-rfs-group.c: all references to the conversion must be updated to use RTEMS_RFS_SUPERBLOCK_SIZE explicitly.
  1. rtems_rfs_group_block converts the pair to bno via:
    #define rtems_rfs_group_block(_g, _b) (((_g)->base) + (_b))
    

(_g)->base is calculated via rtems-rfs-format.c from:

#define rtems_rfs_fs_block(_fs, _grp, _blk) \
  ((((_fs)->group_blocks) * (_grp)) + (_blk) + 1)

The "+ 1" part should really be "+ RTEMS_RFS_SUPERBLOCK_SIZE" to be logically correct. As RTEMS_RFS_SUPERBLOCK_SIZE itself has a comment saying:

/**
 * Number of blocks in the superblock. Yes I know it is a superblock and not
 * superblocks but if for any reason this needs to change it is handled.
 */

The file libcpu/i386/cpu.h provides functions referenced in rtems/score/i386.h Relatedly, libcpu/i386/cpu.h is the only other consumer than score/cpu.h of the score/interrupts.h. The libcpu/i386/cpu.h should be refactored into rtems/score/i386.h, which could also then subsume rtems/score/interrupts.h.

bootstrap sort inconsistent with sb-bootstrap for acinclude

Description

The output of bootstrap does not use a consistent sort order with sb-bootstrap. The difference appears to be in the default behavior of the sort command versus Python's sorted. By forcing the locale to C, sort should have a consistent behavior.

Summary

Add coverage report generation support to rtems-tools

Description

This ticket is to capture the current state of the project started by Krzysztof Mięsowicz <krzysztof.miesowicz@…>. The goals of the project were to:

  • replace the existing shell scripts in rtems-testing with Python code integrated into rtems-tools
  • add the capability to generate a report per directory. This is important because a large body of code with low coverage negatively impacts the overall coverage area and makes reports harder to read. Breaking the reports down by functional area lets us do coverage reporting on more code even when some of the areas are in need of testing improvement.

The remaining effort in conjunction with other activity related to coverage such as inclusion of gcov generated reports is a good "summer of code" type project. This is an important capability to add to the rtems-tools.

The attached tar file krzy-patches.tar.bz2 contains the current code. There may be other issues to resolve but writing from memory, the following are the highest priority ones:

  • no default setting for coverage enable/disable
  • configuration file has hard coded paths. This should be able to be a template which is adjusted by the tools at run-time.
  • variable naming and coding style does not match that used in other Python code in rtems-tools

Krzysztof wrote some in his blog about this (http://kmiesowicz.blogspot.com/p/esa-socis-2014.html). Ensure that your base RTEMS tools are built with the RTEMS Source Builder and check on the development list if it builds a qemu with coverage support. This may have changed since he blogged.

sp07 needs to be split into an user extensions and a notepad test

Description

I was reviewing all code in the tree which uses deprecated methods. I will fix most of the cases. This is going to take a little more time. This test needs to be split apart. I think the notepad usage can go into a new test spnotepad02. It is primarily ensuring that two threads can exchange values through notepads.

The remaining use of notepads in sp07 can probably just be a count down on the priority.

I am starting to move code to spnotepad02 from sp07 that is not related to the tasks counting down.

Hopefully I can resolve this without much feedback.

I am addressing almost all uses of deprecated methods. They are mostly calls to rtems_clock_get() which can be easily corrected or test code which will be removed when the deprecated feature is removed.

This BSP however has what appears to be a unique feature -- the ability for a thread to add a unique exception fault handler. My inclination is to rip this out but I am not doing it now. I am just turning off deprecated warnings for the file.

Create a Public API for the Atomic Operations

Description

Ticket #2364 regarded use of a pthread mutex in three graphics driver as basically an atomic flag to ensure only one open() was active at a time. This created an unnecessary dependency on the POSIX API being enabled. I changed the code to use score Atomic flags.

This highlighted the need for a public Atomic API.

The existing tests could be converted to the public API, a macro wrapper written for Classic API Atomics, and documentation added. This may be enough to be a small GSOC project.

Remove AVR Architectural Port

Description

Remove the AVR port per the instructions at https://devel.rtems.org/wiki/Developer/Removing_a_Port.

All BSPa must be removed before the architectural port can be removed. These are tracked by the following tickets:

Rationale: The AVR port is incomplete and the largest AVR CPU models are just barely large enough to run RTEMS. This by itself is not enough to drop the port. However, the state of GCC for this target is poor. It is marginally maintained. Atmel maintains their own patch set independent of GCC. Plus they use their own small (and unique) C Library. This makes avr-rtems the only user of AVR+newlib. The target size is a challenge but that was why the port was initially interesting. It provided a real goal. But the tool state is painful for a port which is incomplete and has neither users nor anyone interested in actively maintaining it for GCC or RTEMS.

Add Thread Local Storage (TLS) support on x86

Description

The x86 is one of the architectures which does not support Thread Local Storage. Each architecture requires target architecture specific support to provide this standard language feature.

Details on the implementation by the compiler may be found at http://wiki.osdev.org/Thread_Local_Storage.

Based on this information, I think a segment register needs to be added to the thread context and some hooks to the TLS implemented.

Architecture information on TLS implementation should be added to the CPU Supplement document as this is part of the ABI and context switch.

As part of effort, the documentation for the general procedure of adding target specific TLS support should be added to the porting guide or reviewed.

Review cxx_iostream size change per function-section changes

Description

It looks like some BSPs with their own linkcmds may have shrunk too much. Norm appears to be 50% while some went to 75-80%. A second look after catching the pattern indicates that the KEEP() section requirements in the linker scripts were not correct and it was missed.

Rather than reverting a bunch of patches, this ticket is to review all function-section patches from this one back in time for cxx_iostream shrinking too much.

arm/lpc176x: linker script update (add KEEP() sections)

Description

This BSP's linker script does not include KEEP() directives and thus cannot have per-function and per-data element section support enabled.

The preferred solution is to convert the BSP to use a shared base linker script. The acceptable solution is to add the proper KEEP directives to the existing linker script(s).

Shared linker scripts for the arm, m68k, and sparc have the proper KEEP sections and can serve as examples.

POSIX Condition Variables Clock Attribute Support

Description

I am beginning to add support for the clock attribute to POSIX condition variables.

http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_condattr_getclock.html

Since the clock can't be a CPU time clock, that leaves CLOCK_MONOTONIC and CLOCK_REALTIME. The thread queue is based on CLOCK_MONOTONIC and does not have an option to use CLOCK_REALTIME. Threads and timers waiting on CLOCK_REALTIME should be impacted by time of day changes.

https://docs.google.com/document/d/1GsGer0t84p-nUfZFim4Ty0LTDYNhgKBvlwip_gLQjTY/edit?usp=sharing is a Google doc with my notes so far in it on POSIX clocks. I will move it to the Wiki as it turns into something more concrete than notes and reflects plans/code.

So the first issue is how best to alter the thread queue to support using either clock source? And what does that do to the current ticks based API since you proposed different time representations for the ticks (relative/monotonic) and seconds (absolute/realtime) structures?

rtems_heap_allocate_aligned_with_boundary() body and prototype inconsistent

Description

The first parameter is size_t in the .h and uintptr_t in the body. This resulted in a compiler error on the m32c. But it is an inconsistency which should be fixed even if no architecture complained.

The malloc.h header file has this:

void *rtems_heap_allocate_aligned_with_boundary(

size_t size, uintptr_t alignment, uintptr_t boundary

);

malloc_deferred.c has this:

void *rtems_heap_allocate_aligned_with_boundary(

pc386: ld -r issue with per function sections

Description

The pc386 BSP has an issue with "ld -r" when function-sections is enabled which does not seem to occur on any other BSP. The same lines were added to the custom .cfg file as on other BSPs. It is unknown at this point whether this is an x86 specific "ld -r" issue or a pc386 build configuration issue.

Per-function-section linking is disabled until this is addressed.

Summary

pc386 BSP has complex dependencies

Description

In 4.11, the minimum executable did not include open() and close() because the methods rtems_libio_post_driver() and rtems_libio_exit() were not included in the executable. On the master, these two methods are showing up in minimum and pulling in these methods.

The dependency chain used to be if the console driver was installed, we needed to open and close stdin, stdout, and stderr. Now even without the console configured these are included.

FWIW the minimum size looks pretty good on the master for sis. Fixing this would likely drop it at least another 5%.

linking issue for htonl, etc when using -std=c99

Description

When -std=c99 is on the compile line, there is a linking error for undefined references to htonl, htons, ntohl, and ntohs. This test case is just for htonl but others should be similar.

This likely impacts the 4.11 branch of rtems-libbsd as well but I was testing on master.

Test case ====================== #include <arpa/inet.h>

int main(

int argc, char argv

) {

uint32_t v = (uint32_t) argc; uint32_t rc = htonl(v); return v;

} ======================

This script was what I used to find what caused the linking error to go away.

Add posix_devctl()

Description

The posix_devctl() method is defined in POSIX 1003.26 and required by the FACE POSIX profiles. The only use case that needs to be supported is FIONBIO on sockets per the FACE Technical Standard.

ioctl() is not a standardized method per POSIX and is not included in the FACE Profiles.

Making operations non-blocking can also be done with fcntl() but due to RTOS qualification concerns, fcntl() is not included in the more stringent FACE profiles. Specifically, it is not in the Safety Base profile which matches the RTEMS POSIX capabilities.

This requires adding the <devctl.h> file to newlib. That has been done. I am testing my implementation but a tool update will be needed before this can be pushed to the community. This is OK because we have other reasons to move to a new gcc and newlib version soon.

Update POSIX 1003.1 Compliance Guide for ReST

Description

The POSIX 1003.1 Compliance Guide should be auto-generated from a spreadsheet into the ReST format. My vague recollection is that we used shell scripts to do this for texinfo output.

I will have to decipher what we used to do and define a new procedure.

This impacts 4.11 and newer. One issue is having correct information for what methods are present on a branch. The FACE Conformance Test Suite can be used for ~800 of the methods.

RSB requirements are missing pax

Description

Loading a new VM, I noticed that pax is needed. It isn't mentioned in the RSB manual at all.

I can only accurately fix this for Centos 7 but we can safely assume that advice applies to Centos 6, Fedora, and RHEL.

Can users of other distributions check about pax. Please

Questionable Code in resource_snapshot.c

Description

Coverity URL:

Coverity Scan doesn't like taking the address of a single uint32_t and then treating it as an array pointer. I think the code is likely doing what is intended but there is an implicit linkable between the order of the fields in the structure here and the class numbers used in the object IDs. Is there a way to improve this code and reduce the linkage?

141

  1. address_of: Taking address with &snapshot->active_posix_keys yields a singleton pointer.
  2. assign: Assigning: active = &snapshot->active_posix_keys.

  1. Condition i < 19U /* sizeof (objects_info_table) / sizeof (objects_info_table[0]) */, taking true branch.

  1. Condition information != NULL, taking true branch.

152 if (information != NULL) { CID 1399703 (#1 of 1): Out-of-bounds access (ARRAY_VS_SINGLETON)

  1. ptr_arith: Using active as an array. This might corrupt or misinterpret adjacent memory locations.

This was originally discussed here (https://sourceware.org/ml/newlib/2013/msg00626.html) with follow up discussion here (https://sourceware.org/ml/newlib/2017/msg00240.html).

The consensus seems to be that the methods as currently implemented in FreeBSD address the concerns raised in that email thread.

This ticket is complete when:

  • source for these methods is merged into newlib
  • methods are documented in newlib
  • RSB is updated appropriately
  • tests are added to RTEMS
  • RTEMS POSIX Compliance spreadsheet (https://goo.gl/AXrnxO) is updated

It looks like there are two issues in windows.py

  • tar - bsdtar must be on mingw. It doesn't appear to exist on cygwin.

I think the fix is pretty simple code-wise but I wanted to get some feedback on why there were a lot more required programs in this file than on other OS.py files.

getreent in libc.a and generated by confdefs.h

Description

Some applications are getting duplicate symbol definitions for getreent(). One of the examples-v2 programs is doing this. It is because there are two bodies for this method -- one from confdefs.h and another from newlib.

https://sourceware.org/ml/newlib/2017/msg01020.html addresses the issues and needs to be incorporated by the RSB.

https://sourceware.org/ml/newlib/2017/msg01019.html is a cleanup that was spotted at the same time. It can be picked up by a newlib snapshot.

smptests/Makefile.am Issues

Description

There appear to be two issues in smptests/Makefile.am:

  1. smppsxaffinity0[12] are listed twice. This causes a warning. I am unsure if they should always be built or only when POSIX is enabled.
  1. smppsxmutex01 is listed in the "HAS_POSIX" section. Aren't POSIX mutexes always on now so this test should not be inside the conditional?

I was updating the md5's to sha512's on qemu and made a typo which resulted in this message:

The error message did not result in the build aborting. Perhaps this should be a fatal error.

sb-check fails on Msys2 64-bit

Description

There must be a recent change to msys2 which is breaking things. I installed the 64-bit version from https://msys2.github.io/ per the instructions at https://docs.rtems.org/branches/master/user/hosts/index.html#microsoft-windows

$ ./source-builder/sb-check
error: no hosts defaults found; please add

After adding some prints, I learned this:

$ ./source-builder/sb-check
posix
made it
MSYS_NT-10.0
error: no hosts defaults found; please add

I filled in options.py and windows.py to recognize this as MSYS2. I was then able to run sb-check. But it wasn't happy. Apparently the pacman command in the User's Guide is missing some packages based on newer versions:

$ ./source-builder/sb-check

Warning in all lpc176x variants

Description

bsps/arm/lpc176x/include/bsp.h defines OPERATION_COUNT in an attempt to override the autoconf generated constant. This conflicts and results in this warning:

/home/joel/rtems-work/rtems-testing/rtems/rtems/bsps/arm/lpc176x/include/bsp.h:42:0: warning: "OPERATION_COUNT" redefined

I understand why this is lowered by the BSP but the mechanism used is not good. And if the include file order is different between tests, you could get the BSP value or the autoconf generated value based on the order.

This warning needs to be fixed and a safer mechanism for a BSP to override OPERATION_COUNT defined.

My first suggestion is to use BSP_OPERATION_COUNT and add logic to one of the common test .h files to undef OPERATION_COUNT and redefine it to BSP_OPERATION_COUNT if it is defined.

A safer option might be to change the name of the autoconf generated variable to OPERATION_COUNT_DEFAULT and rely on logic in a common test support .h to define OPERATION_COUNT to OPERATION_COUNT_DEFAULT or BSP_OPERATION_DEFAULT.

Remove Simple SMP Priority Scheduler

Description

This scheduler was the first SMP scheduler added. It was created to have an easy SMP scheduler to debug. This was especially important when all of the SMP modifications and support were new. A Simple Scheduler has a use case as a low resource alternative for small uniprocessor systems. But the SMP variant just doesn't seem to have a good use case. If you have an SMP system, the application is almost certain to have enough resources where the more complicated data structures used by the other schedulers wouldn't be a burden. The Deterministic Priority Scheduler uses ~3K for FIFO with 256 priorities. This should not be an issue for an SMP system.

This ticket is a proposal to remove this as no longer having a use case.

sb-set-builder should report disk usage of build

Description

Helping others work through the hello world, it is common for their VM images to not have enough disk space for the build to complete. It would be useful if the set-builder could report disk usage of the build/ directory. This information could be fed into the Users Guide.

It is frustrating and a bad experience to watch the build fail 90% of the way through.

Add programs to report default attributes for various POSIX objects including barriers, condition variables, message queues, mutexes, pthreads, and rwlocks. The programs should be able to run on any POSIX host and report what it uses for object attribute defaults.

Object attribute defaults are unspecified by POSIX. The portable practice is to explicitly set every attribute. These programs allow one to probe and compare various operating system implementations.

Summary

fishy behavior in termios tx task mode

Description

I have a look around in the drivers in the various BSPs and I notice that none of the termios drivers appear to transmit characters at task level even if they are running in termios task mode. Maybe all (most) of them send characters in the ISR. If there was a large frame of characters to send then this could lock out task activity for too long.

FWIW, I had a closer look at this today, and maybe something is fishy in the termios code when the TX part of termios runs in task driven mode. It seems that in task mode if the UART can accept characters immediately in the write routine then we wouldn’t need to turn on any interrupts at all. The write routine would need to somehow tell termios how many characters it sent; presumably this would occur by calling rtems_termios_dequeue_characters in the driver's write function. I see in the code that this tries to work, rtems_termios_dequeue_characters posts the semaphore of termios tx and increases the characters sent count of termios. However after the write routine returns it goes badly.

If the transmitter runs in termios TASK mode and the driver's write routine does not immediately enable an interrupt, then it returns to the code below in rtems_termios_puts and it sets the transmitter to rob_busy. After that the termios tx daemon proceeds to step through all of the characters remaining (I think that I see this in the debugger) and discards them because the transmitter stays in rob_busy state.

It's also probably odd that termios calls the write function with interrupts disabled when it is in task driven mode; we could loop outputting a large frame of characters in the write routine at task level with interrupts globally disabled.

if (tty->rawOutBufState == rob_idle) {

/* check, whether XOFF has been received */ if (!(tty->flow_ctrl & FL_ORCVXOF)) {

(*tty->device.write)(tty->minor,

(char *)&tty->rawOutBuf.theBuf[tty->rawOutBuf.Tail],1);

} else {

/* remember that output has been stopped due to flow ctrl*/ tty->flow_ctrl |= FL_OSTOP;

} tty->rawOutBufState = rob_busy;

}

Summary

rtems_iterate_over_all_threads lacks user callback private pointer pass through

Description

Typically when designing an API that calls a user callback there is a user private "void *" pointer transparently passed through to the user callback so that the user can access his private state inside of his callback without being forced to employ a global variable. A global variable doesnt work very well if there are multiple objects instances created each of them using the same method with rtems_iterate_over_all_threads. This type of "void *" private pointer is of course a standard approach allowing the users callback to behave much the same way as a virtual method in C++, but nevertheless retaining a compatible C based API.

An enhanced version of the API might look like this.

void rtems_iterate_over_all_threads_xxx( rtems_per_thread_routine routine, void * const pUserPrivatePassThrogh );

typedef void (*rtems_per_thread_routine_xxx)( Thread_Control *the_thread, void * const pUserPrivatePassThrogh );

The pUserPrivatePassThrogh is not used by the library; it is retained for the duration of the rtems_iterate_over_all_threads_xxx function only so that it can be passed through to the user's callback.

thanks for your consideration of this matter

RTL Unresolved Symbols from common section on i386/pc686 (cloned)

Description

Cloned from #3527:


By default GCC puts uninitialized global variables into a common section in the ELF file. When attempting to load the resulting ELF file at runtime using dlopen(), these global symbols are not resolved as expected.

The RTL reports unresolved symbols, and runtime code that take the address of the global get NULL instead.

This is reproducible using the libtests/dl01 example by adding a global variable to the module code. I will attach a patch that replicates the issue.

Test platform is QEMU using pc686 BSP, RTEMS source version 4.11.3 (latest on 4.11 git branch as of this writing)

Overrun Handling for general real-time models

Description

In the current implementation, if a task period is time out, the next call of rtems_rate_monotonic_period() will only release one following job and manipulate the task period with the calling moment + the next length of period. With the assumption that implicit/constraint deadline and hard real-time model, the above mechanism is okay.

However, it may not be applicable for general task models, e.g., soft real-time task, arbitrary deadline, mixed-criticality system [1-4]. It is usually assumed that multiple task jobs of a task are executed in a first-come-first-serve manner. Thus, it is sufficient to release the second task job at the moment the first task job finishes according to a strictly periodic release pattern. The current design in fact shifts the release pattern of periodic/sporadic tasks. Since there maybe more than one postponed jobs due to the preemption, these postponed jobs that should be released are never released to the system.

Although there is no standard requirement in reality for deadline misses, with this enhancement, the postponed jobs will be released with the correct number without periodic release shifting. This way of handling is already widely considered in academia from 90s [2] until now [3] or even on multicores as well [4].

I refine the following four files and handle this requirement individually. The overhead seems to me negligible. cpukit/rtems/include/rtems/rtems/ratemon.h cpukit/rtems/include/rtems/rtems/ratemonimpl.h cpukit/rtems/src/ratemontimeout.c cpukit/rtems/src/ratemonperiod.c I have tested the enhancement on Qemu and Raspberry Pi Model B+ with corresponding BSPs.

I believe this patch as a basis is required for further use for more general real-time task models. This enhancement only affect those timeout cases without changing any behaviour in normal cases. This enhancement is accepted in workshop mixed-criticality (WMC 2016) along with RTSS'16 this year [5].

To demonstrate the differences, a heuristic example is prepared in testsuites/sptests/sprmsched01 to show the benefit of the enhancement: Given two tasks with implicit deadline that task deadline is equal to its period. Task 1 period is 10000 ticks, whereas task 2 is 2000 ticks. Task 1 has the execution time 6000 ticks, and task 2 has 1000 ticks. Assume Task 1 has a higher priority than task 2. Task 1 only executes 2 times. In the expected result, we can observe that the postponed jobs are continuously released till there is no postponed job left, and the task period will still keep as it is. (Job 3-7 in task 2 are postponed jobs)

Update termios.h to match the latest FREEBSD definitions

Description

The FREEBSD struct termios separates out the input and output baud rates into individual speed_t variables. It also supports more flag options. The big benefit is that the rtems-libbsd tty code can be ported cleanly without the need to fixup the input and output baud rates. This should be a transparent change unless someone was manipulating the baud rates directly through the c_cflags (not using the cfgetispeed, cfgetospeed, cfsetispeed, cfsetospeed functions).

Termios task driven mode not compatible with SMP

Description

When the Termios task driven functioning mode is used, rtems_termios_open_tty() calls rtems_task_create() with RTEMS_NO_PREEMPT in the initial task mode parameter. RTEMS_NO_PREEMPT is not supported on SMP.

rtems_task_create() returns RTEMS_UNSATISFIED in this SMP scenario and Termios ends up in rtems_fatal_error_occurred().

Termios starts the RX and TX tasks successfully on SMP if RTEMS_NO_PREEMPT is removed from the initial task modes of these tasks. However, I suspect there may be assumptions on the NO_PREEMPT mode for the RX and TX tasks in other parts of Termios.

FAT does not support clusters bigger than 32K

Description

When used with 64KiB clusters, the FAT driver will loop forever in cpukit/libfs/src/dosfs/fat.c, line 580. This happens because struct fat_vol_s declares bytes per cluster variable as uint16_t bpc, whereas it can be as big as 256KiB.

ARM caching issues

Description

There are two problems with the caching on ARM:

  • In cases where the buffer is not aligned to line boundary at the beginning or the end, the invalidate operation would lose modifications done on the adjacent data. This applies to both L1 and L2 caches.
  • The L2C-310 cache management operations use excessive locking. According to manual, the used operations (Clean Line by PA, Clean and Invalidate Line by PA, Cache Sync) are atomic and do not require locking.

I have attached the proposed patch.

There is a section - 22.2.4 (Order of Invocation) that does discuss the operation of the sets, but it only makes sense once the reader understands that the sets are, in fact, additive.

The watchdog lock is highly contended and since the watchdog insert procedure acquires and releases the lock during the iteration of the watchdog chain several times, this yields the high thread dispatch disabled times.

To get rid of this bottleneck we should move the watchdog context into the scheduler context to use one watchdog context per scheduler instance. Take care that active watchdogs move in case of a scheduler change of a thread.

Replace red-black tree implementation, change API

Proposal:

https://github.com/sebhub/rb-bench/blob/master/test-rbtree-bsd-for-rtems.c

One benefit is that the search/insert is done inline and the red-black tree fixup is done in a general purpose _BSD_RBTree_Insert_color() function (similar to the Linux red-black tree API).

This makes it possible to get rid of the red-black tree implementation used by the JFFS2 support.

Enable function and data sections

Description

In order to reduce the size of executables it is beneficial to put all global functions and data into separate sections. This enables the linker to perform a garbage collection which removes all items not directly referenced. The following steps are necessary:

  1. Modify the build system to use the following compiler and linker flags:

CFLAGS += -ffunction-sections -fdata-sections LDFLAGS += -Wl,--gc-sections

  1. Review all linker command files and ensure that linker sets and global constructor sections are not affected by the garbage collection (e.g. use the KEEP() directive of GNU ld).

Linker set based initialization

Description

Linker sets are used for example in Linux, FreeBSD (they are used in the RTEMS port of the FreeBSD network stack, e.g. libbsd), eCos and for global C++ constructors. They provide a space efficient and flexible means to initialize modules. A linker set consists of

  • dedicated input sections for the linker (e.g. .ctors and .ctors.* in the case of global constructors),
  • a begin marker (e.g. provided by crtbegin.o, and
  • an end marker (e.g. provided by ctrend.o).

A module may place a certain data item into the dedicated input section. The linker will collect all such data items in this section and creates a begin and end marker. The initialization code can then use the begin and end markers to find all the collected data items (e.g. function pointers).

Lets look how this works using a simple example. For this we need three files myset.h,

#ifndef MYSET_H
#define MYSET_H

/* The linker set items */
typedef struct {
  void (*func)(void);
} item;

/*
 * Macro to create a linker set item.  The first parameter is
 * the designator of the item.  It must be unique within the
 * module scope.  The second parameter is the desired function.
 */
#define MYSET_ITEM(i, f) \
    __attribute__((used)) \
    __attribute__((section(".rtemsroset.myset.content"))) \
    static item i = { f }

#endif /* MYSET_H */

module.c

#include "myset.h"
#include <stdio.h>

/*
 * Some global function that needs a module specific
 * intialization done by f().
 */
void
g(void)
{

        printf("g()\n");
}

/* The module constructor */
static void
f(void)
{

        printf("f()\n");
}

/*
 * This registers the module constructor f()
 * in the linker set "myset".
 */
MYSET_ITEM(i, &f);

and init.c.

#include "myset.h"
#include <stddef.h>

/* Should be in a proper header file */
void g(void);

/* Define the start marker */
__attribute__((used))
__attribute__((section(".rtemsroset.myset.begin")))
static volatile const item begin[0];

/* Define the end marker */
__attribute__((used))
__attribute__((section(".rtemsroset.myset.end")))
static volatile const item end[0];

int main(void)
{
        size_t n = &end[0] - &begin[0];
        size_t i;

        /* Call all functions of the linker set */
        for (i = 0; i < n; ++i) {
                (*begin[i].func)();
        }

        /*
         * This will pull in the module.c and register its item in the
         * linker set "myset".  So g() can rely on f() being called first.
         */
        g();

        return (0);
}

In the linker command file of the GNU linker we need the following statement.

.rtemsroset : {
	KEEP (*(SORT(.rtemsroset.*)))

The KEEP() ensures that a garbage collection by the linker will not discard the content of this section. This would be normally the case since the linker set items are not referenced directly. The SORT() directive sorts the input sections lexicographically. Please note the lexicographical order of the .begin, .content and .end section name parts in the previous example which ensures that the position of the begin and end markers are right. The interesting part of linker map file of the previous example may look like this.

.rtemsroset     0x0000000001001990        0x4 load address 0x000000000002268c

So what is the benefit of using linker sets to initialize modules? Currently in RTEMS all available managers (semaphore, message queue, barrier, etc.) are initialized since the initialization code doesn't know what is actually used by the application. With the linker set approach we need to initialize only those managers that are used by the application. In case an application uses message queues, then it must call rtems_message_queue_create(). In the module implementing this function we can place a linker set item and register the message queue handler constructor. Otherwise, in case the application doesn't use message queues, then there will be no reference to the rtems_message_queue_create() function and the constructor is not registered, thus nothing of the message queue handler will be in the final executable.

Summary

Improved priority inheritance implementation

Description

Problem

The RTEMS mutexes implement only a very simple approximation of the priority inheritance protocol. The real priority of a thread is only restored once it releases its last mutex. Lets consider this scenario. We have a file system instance protected by one mutex (e.g. JFFS2) and a dynamic memory allocator protected by another mutex. A low priority thread performs writes some log data into a file, thus it acquires the file system instance mutex. The file system allocates dynamic memory. Now a high priority thread interrupts and tries to allocate dynamic memory. The allocator mutex is already owned, so the priority of the low priority thread is raised to the priority of the high priority thread. The memory allocation completes and the allocator mutex is released, since the low priority thread still owns the file system instance mutex it continues to execute with the high priority (the high priority thread is not scheduled). It may now perform complex and long file system operations (e.g. garbage collection, polled flash erase and write functions) with a high priority.

Functional requirements

  • The mutex shall use the priority inheritance protocol to prevent priority inversion. On SMP configurations OMIP shall be used.
  • The mutex shall allow vertical nesting (a thread owns multiple mutexes).
  • The mutex shall allow horizontal nesting (a thread waits for ownership of a mutex those owner waits for ownership of a mutex, and so on).
  • Threads from one scheduler instance shall wait in priority order. The highest priority thread shall be dequeued first.
  • The highest priority waiting thread of each scheduler instance shall wait in FIFO order.
  • The mutex shall provide an acquire operation with timeout.
  • In case a mutex is released, then the previous owner shall no longer use the priorities inherited by this mutex.
  • In case a mutex acquire operation timeout occurs, then the current owner of the mutex shall no longer use the priorities inherited by the acquiring thread.
  • The order of the mutex release operations may differ from the order of the mutex acquire operations.
  • Priority changes not originating due to the priority inheritance protocol shall take place immediately.
  • Deadlock shall be detected. In case a deadlock would occur an error status shall be returned or a fatal error shall be generated.
  • Deadlocks at application level shall not lead to a deadlock at operating system level.

Performance requirements

  • The mutex acquire operation shall use only object-specific locks in case the mutex is not owned currently.
  • The mutex release operation shall use only object-specific locks in case no threads wait for ownership of this mutex.

Invariants

  • A mutex shall be owned by at most one thread.
  • A thread shall wait for ownership of at most one mutex.

Possible implementation

Use a recursive data structure to determine the highest priority available to a thread for each scheduler instance, e.g.

typedef struct Thread_Priority_node {
  Priority_Control current_priority;
  Priority_Control real_priority;
  struct Thread_Priority_node *owner;
  RBTree_Node Node;
  RBTree_Control Inherited_priorities;
} Thread_Priority_node;

typedef struct {
  ...
  Thread_Priority_node *priority_nodes; /* One per scheduler instances */
  ...
} Thread_Control;

Initially a thread has a priority node reflecting its real priority. The Thread_Priority_node::owner is NULL. The Thread_Priority_node::current_priority is set to the real priority. The Thread_Priority_node::Inherited_priorities is empty.

In case the thread must wait for ownership of a mutex, then it enqueues its priority node in Thread_Priority_node::Inherited_priorities of the mutex owner.

In case the thread is dequeued from the wait queue of a mutex, then it dequeues its priority node in Thread_Priority_node::Inherited_priorities of the previous mutex owner (ownership transfer) or the current mutex owner (acquire timeout).

In case the minimum of Thread_Priority_node::real_priority and Thread_Priority_node::Inherited_priorities changes, then Thread_Priority_node::current_priority is updated. In case the Thread_Priority_node::owner its not NULL, the priority change propagates to the owner, and so on. In case Thread_Priority_node::current_priority changes, the corresponding scheduler is notified.

The biggest issue is the locking on SMP configurations in case of recursive minimum updates.

Somehow we must connect this to the scheduler helping protocol for OMIP. We may have to replace the return value based scheduler operations with a pre-context-switch action. Due to some recent implementation changes the run-time of the _Thread_Dispatch() function is no longer average-case performance critical.

New watchdog handler implementation

Description

Background

The watchdog handler uses delta chains. The insert operation has a O(n) worst-case time complexity with n being the count of watchdogs in the delta chain. In each step of the insert operation, the SMP lock of the corresponding watchdog header is acquired and released. The profiling data obtain by test program smptests/smpwakeafter01 showed that the current implementation leads to unacceptable latencies, thus it should be replaced by something else.

The use cases for the watchdog handler fall roughly into two categories.

  • Timeouts - used to detect if some operations needs more time than expected. Since the unexpected happens hopefully rarely, timeout timers are usually removed before they expire. The critical operations are insert and removal. They are important for the performance of a network stack.
  • Timers - used to carry out some work in the future. They usually expire and need a high resolution. An example user is a time driven scheduler, e.g. rate-monotonic or EDF.

One approach is to use a red-black tree with the expiration time as the key. This leads to O(log(n)) worst-case insert and removal operations. For each operation it is sufficient to acquire and release the lock only once. The drawback is that a 64-bit integer type must be used for the intervals to avoid a potential overflow of the key values. With a system tick interval of 1ns the system could run more than 500 years before an overflow happens. The EDF scheduler would also profit from a 64-bit interval representation, see #2173.

An alternative is the use of a timer wheel based algorithm which is used in Linux and FreeBSD for example. A timer wheel based algorithm offers O(1) worst-case time complexity for insert and removal operations. The drawback is that the run-time of the watchdog tick procedure is somewhat unpredictable due to the use of a hash table or cascading.

Which approach should we choose? Since the watchdog serves the timeout and timer services in RTEMS we have to make some trade-offs. We recommend to use the red-black tree approach which offers a more predictable run-time behaviour and sacrifice the constant insert and removal operations offered by the timer wheel algorithms, see also https://www.kernel.org/doc/ols/2006/ols2006v1-pages-333-346.pdf. We can reuse the red-black tree support already used for the thread priority queues.

The new watchdog handler implementation is a prerequisite to eliminate the Giant lock in the Classic Timer manager.

Implementation

Change the _Watchdog_Ticks_since_boot to a 64-bit integer type. Keep the Watchdog_Interval at 32-bit for backward compatibility. Replace the delta chains with a red-black tree. Use the ticks for timers with a relative expiration time. Use struct timespec or struct bintime for timers with an absolute expiration time. This has the benefit that we do not have to adjust the data structures in case the absolute time changes, e.g. due to NTP. It simplifies the POSIX timer services, since no conversion to ticks is necessary.

Eliminate the Giant lock

Description

Background

The standard approach to turn a uni-processor operating system into an SMP-capable operating system is to encapsulate virtually the complete operating system state and protect it by one global recursive lock - the Giant lock. Thus, at most one processor can modify the operating system state at a time. Under Giant lock protection interrupt disable/enable critical sections still work. This approach is easy to realize and leads to something that runs on SMP with a minimal effort. Unfortunately, such an operating system does not scale with the processor count and offers very poor performance. It is quite useless for real applications.

The first steps to get rid of the Giant lock are tackled with the introduction of fine grained locking for the scheduler, watchdog handler, timestamps, thread queues, events, semaphores and message queues. The Giant lock is still used in a couple of places, e.g. all other objects using thread queues, thread life cycle changes (termination, restart) and scheduler changes. It is a straight forward task to eliminate it entirely, but it is also somewhat labour intensive since a lot of code must be changed.

Implementation

Eliminate all remaining code areas that use

  • _ISR_Disable(),
  • _ISR_Enable(), and
  • _ISR_Flash().

Direct users of these macros are

  • _Chain_Append(),
  • _Chain_Extract(),
  • _Chain_Get(),
  • _Chain_Insert(), and
  • _Chain_Prepend().

Each spot must be dealt with individually. Once this is done, delete these macros since they are now superfluous. Rename _ISR_Disable_without_giant() into _ISR_Locale_disable(). Rename _ISR_Enable_without_giant() into _ISR_Locale_enable().

Eliminate all remaining code areas that use

  • _Thread_Disable_dispatch() and
  • _Thread_Enable_dispatch().

A prominent user of this functions is _Objects_Get(). The following components are affected by these functions

  • Classic barrier handler,
  • Classic dual-ported memory handler,
  • Classic message queue handler,
  • Classic partition handler,
  • Classic rate-monotonic handler,
  • Classic region handler,
  • Classic semaphore handler,
  • Classic timer handler,
  • extension handler,
  • IO manager,
  • multi-processing management,
  • objects management,
  • POSIX barrier handler,
  • POSIX condition handler,
  • POSIX key handler,

  • POSIX semaphore handler,
  • POSIX spinlock handler,
  • POSIX timer handler,
  • signals,
  • thread cancellation,
  • thread life-cycle changes, and
  • thread scheduler changes.

Once this is done, delete _Thread_Disable_dispatch() and _Thread_Enable_dispatch(). As a side-effect the Giant lock will be removed.

Implement the O(m) Independence-Preserving Protocol (OMIP)

Description

Background

The O(m) Independence-Preserving Protocol (OMIP) is a generalization of the priority inheritance protocol to clustered scheduling which avoids the non-preemptive sections present with priority boosting. The m denotes the number of processors in the system. Its implementation requires an extension of the scheduler helping protocol already used for the MrsP semaphores. However, the current implementation of the scheduler helping protocol has two major issues, see Catellani, Sebastiano, Luca Bonato, Sebastian Huber, and Enrico Mezzetti: Challenges in the Imple- mentation of MrsP. In Reliable Software Technologies - Ada-Europe 2015, pages 179–195, 2015. Firstly, the run-time of some scheduler operations depend on the size of the resource dependency tree. Secondly, the scheduler operations of threads which don't use shared resources must deal with the scheduler helping protocol in case an owner of a shared resource is somehow involved.

To illustrate the second issue, let us look at the following example. We have a system with eight processors and two L2 caches. We assign processor 0 to a partition P for latency sensitive real-time tasks (e.g. sensor and actuator handling), processors 1, 2 and 3 are assigned to a cluster CA and the remaining processors are assigned to a cluster CB for soft real-time worker tasks. The worker tasks use a shared resource, e.g. a file system for data storage. Let us suppose a task R of partition P sends a message to the workers. This may make a waiting worker ready, which in turn pre-empts the owner of a shared resource. In this case the scheduler helping protocol takes action and is carried out by the task R. This contradicts the intended isolation of scheduler instances.

The reason for this unfortunate coupling is a design issue of the scheduler helping protocol implementation. Some scheduler operations may return a thread in need of help. For example, if a thread is unblocked which pre-empts an owner of a shared resource, then the pre-empted thread is returned. Once a thread in need of help is returned, the ask for help operation of the scheduler is executed. An alternative to this return value based approach is the introduction of a pre-emption intervention during thread dispatching. Threads taking part in the scheduler helping protocol indicate this with a positive resource count value. In case a thread dispatch occurs and pre-empts an owner of a shared resource, the scheduler ask for help operation is invoked. So, the work is carried out on behalf of the thread which takes part in the scheduler helping protocol.

To overcome the first issue, an improved resource dependency tracking is required. One approach is to use a recursive red-black tree based data structure, see #2412.

Implementation

There are several steps necessary to implement OMIP.

  • Introduce per-scheduler locks.
  • Enable context switches with interrupts enabled.
  • Add a pre-emption intervention to the thread dispatch.
  • Add a table for priority nodes to the thread control block. For each scheduler instance there is one priority node.
  • Update the table in case the thread blocks on a resource, a timeout while waiting for a resource occurs, or ownership of a resource is transferred to the thread.
  • Use this table in the pre-emption intervention.
  • Update the MrsP implementation to the new infrastructure.

Currently, only one scheduler lock for all scheduler instances is used. This simplified the MrsP implementation and due to the presence of a Giant lock, this was not an issue. With the elimination of the Giant lock, however, we need one scheduler lock per scheduler instance to really profit from a decoupled system due to clustered scheduling.

The current implementation of thread dispatching has some implications with respect to the interrupt latency. It is crucial to preserve the system invariant that a thread can execute on at most one processor in the system at a time. This is accomplished with a boolean indicator in the thread context. The processor architecture specific context switch code will mark that a thread context is no longer executing and waits that the heir context stopped execution before it restores the heir context and resumes execution of the heir thread (the boolean indicator is basically a TTAS lock). So, there is one point in time in which a processor is without a thread. This is essential to avoid cyclic dependencies in case multiple threads migrate at once. Otherwise some supervising entity is necessary to prevent deadlocks. Such a global supervisor would lead to scalability problems so this approach is not used. Currently the context switch is performed with interrupts disabled. Thus in case the heir thread is currently executing on another processor, the time of disabled interrupts is prolonged since one processor has to wait for another processor to make progress.

If we add pre-emption intervention to the thread dispatch sequence, then there is an even greater need to avoid this issue with the interrupt latency. Interrupts normally store the context of the interrupted thread on its stack. In case a thread is marked as not executing, we must not use its thread stack to store such an interrupt context. We cannot use the heir stack before it stopped execution on another processor. If we enable interrupts during this transition, then we have to provide an alternative thread independent stack for interrupts in this time frame.

The pre-emption intervention should be added to _Thread_Do_dispatch() before the heir is read and perform the following pseudo-code actions.

pre_emption_intervention(executing):
	if executing.resource_count > 0:
		executing.lock()
		if executing.is_ready():
			for scheduler in executing.schedulers:
				scheduler.lock()
			if !executing.is_scheduled():
				for scheduler in executing.schedulers:
					scheduler.ask_for_help(executing)
			for scheduler in executing.schedulers:
				scheduler.unlock()
		else if executing.active_help_level > 0:
			idle.use(executing.scheduler_node)
		executing.unlock()

The scheduler help operation affects multiple scheduler instances. In terms of locking we have only two options,

  • use a global scheduler lock, or
  • obtain multiple per-scheduler locks at once.

A global scheduler lock is not an option. To avoid deadlocks obtain the per-scheduler locks in a fixed order. However, in this case the per-scheduler locks will observe different worst-case and average-case acquire times (depending on the order).

Use a recursive data structure to determine the highest priority available to a thread for each scheduler instance, e.g.

typedef struct Thread_Priority_node {
	Priority_Control current_priority;
	Priority_Control real_priority;
	struct Thread_Priority_node *owner;
	RBTree_Node Node;
	RBTree_Control Inherited_priorities;
} Thread_Priority_node;

typedef struct {
	...
	Thread_Priority_node *priority_nodes; /* One per scheduler instances */
	...
} Thread_Control;

Initially a thread has a priority node reflecting its real priority. The Thread_Priority_node::owner is NULL. The Thread_Priority_node::current_priority is set to the real priority. The Thread_Priority_node::Inherited_priorities is empty.

In case the thread must wait for ownership of a mutex, then it enqueues its priority node in Thread_Priority_node::Inherited_priorities of the mutex owner.

In case the thread is dequeued from the wait queue of a mutex, then it dequeues its priority node in Thread_Priority_node::Inherited_priorities of the previous mutex owner (ownership transfer) or the current mutex owner (acquire timeout).

In case the minimum of the Thread_Priority_node::real_priority and the Thread_Priority_node::Inherited_priorities changes, then Thread_Priority_node::current_priority is updated. In case the Thread_Priority_node::owner its not NULL, the priority change propagates to the owner, and so on. In case Thread_Priority_node::current_priority changes, the corresponding scheduler is notified.

Use the thread lock to protect the priority nodes.

RTEMS uses currently a signed 32-bit integer for time_t on Newlib. Thus, it is affected by the year 2038 problem. There are only 22 years left and this time span is within the realistic time frame of some RTEMS applications that are developed now.

The time_t should be changed to int64_t in Newlib. To make sure that all integer operations are carried out properly I suggest to temporarily do this

{{{#include <sys/_stdint.h>

typedef struct {

int64_t _val;

} time_t;

static inline time_t _time_add(time_t a, time_t b) {

time_t r = { a._val + b._val }; return r;

}

static inline time_t _time_sub(time_t a, time_t b) {

time_t r = { a._val - b._val }; return r;

}

static inline time_t _time_mul(time_t a, time_t b) {

time_t r = { a._val * b._val }; return r;

}

static inline time_t _time_div(time_t a, time_t b) {

time_t r = { a._val / b._val }; return r;

} }}}

Make sure that RTEMS and Newlib build with this. Add test cases to highlight the time_t integer limits.

POSIX key destructors must be called during thread restart

Description

POSIX key destructors must be called during thread restart. Just like the POSIX cleanup handlers. This ensures that the TLS object destructors are called during thread restart for example. It is important for the global construction, which uses a thread restart to run the Init task in a clean environment.

Remove descriptor objects for POSIX message queues

Description

The mq_open() function returns a descriptor to a POSIX message queue object identified by a name. This is similar to sem_open(). In contrast to the POSIX semaphore the POSIX message queues use a separate object for the descriptor. This extra object is superfluous, since the object identifier can be used directly for this purpose, just like for the semaphores.

Classic binary semaphores without a locking protocol can be released by everyone

Description

The Classic binary semaphores without a locking protocol can be released by everyone, e.g. in contrast to the POSIX mutexes (all variants) or the Classic binary semphores with priority inheritance or ceiling, there is no owner check in the release path.

This behaviour is a bit unexpected and not documented.

The following test case fails in case an owner check is added:

*** BEGIN OF TEST SP 42 ***
Exercising blocking discipline w/extract in FIFO order 
Exercising blocking discipline w/unblock in FIFO order
TA00 - unblocked - OK

rtems_semaphore_delete FAILED -- expected (RTEMS_SUCCESSFUL) got (RTEMS_RESOURCE_IN_USE)

This is actually a bug in the test, since an available mutex is released again.

Thread dispatch via interrupt is broken at least on ARM and PowerPC

Description

The ARM and PowerPC interrupt epilogues call _Thread_Dispatch() with interrupts disabled (counter example: SPARC).

On SMP configurations, since inter-processor interrupts set the thread dispatch necessary indicator this prevents a thread dispatch notification in post-switch handlers (which all run with interrupts disabled).

On all configurations, this is a serious issue for the interrupt latency.

Relax execution enviroment for thread begin extensions

Description

Currently, the thread begin extensions are invoked with thread dispatching disabled. There is an explanation for this in the code

  /*
   * Take care that 'begin' extensions get to complete before
   * 'switch' extensions can run.  This means must keep dispatch
   * disabled until all 'begin' extensions complete.
   */
  _User_extensions_Thread_begin( executing );

However, the switch extension is always invoked before the thread begin extension for all threads except the initialization thread. A thread dispatch disabled contexts drastically limits the work which can be carried out in the thread begin extensions. It is for example not possible to call malloc(), create POSIX keys or access C++ thread local storage.

The thread begin extension should execute in a normal thread context. Thread begin extensions that are disturbed by a thread dispatch should deal with this locally.

With the availability of C++ thread local storage in RTEMS being able to pre-initialize such objects in the thread begin extension would be quite handy.

Add _CPU_Get_current_per_CPU_control() on SMP configurations as an optimization for PowerPC. Use SPRG0 for the current per-CPU control. This reduces the code size a bit and is slightly faster in some benchmarks.
