11:16 PM Changeset in rtems [9968efb]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
First cut at configuration table for libchip RTC. At this point, we are pretending that the DMV177 has an M48T08.
11:03 PM Changeset in rtems [a1f514f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>

4:20 PM Changeset in rtems [04c5ac7]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed z85c30_flush(). Reworked transmit interrupt processing to remove ring buffer and to mask the TX empty interrupt when it was not expected. This code now uses termios to buffer TX output.
4:18 PM Changeset in rtems [c1da250]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Changed comment on TxBuffer?.

changed version to 980724
4:18 PM Changeset in rtems [03c0961]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from David Fiddes <D.J.Fiddes@…>: Here's a small patch I forgot about from earlier in the week that removes the hack fix Geoffroy had to use to get his BSP to work properly. The termios osend() fix took care of this.
4:09 PM Changeset in rtems [dbab462]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Eric Valette <valette@…> and Emmanuel Raguet <raguet@…> to make their patches work together.

10:13 PM Changeset in rtems [1501809]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
changed version to 980723
10:13 PM Changeset in rtems [dbaf51a]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Emmanuel Raguet <raguet@…>: Here is a patch for KA9Q stack. This patch contains an Ethernet Driver for Western Digital, some fixes for the UDP and TCP protocols (for endian conversion) and some little programs which allow the test of UDP and TCP sockets via Ethernet. I have tested that on an Intel machine. If someone can test it on a big-endian machine, …
10:02 PM Changeset in rtems [67a2288]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Eric VALETTE <valette@…>: Here is a enhanced version of my previous patch. This patch enables to potentially share the new interrupt management code for all Intel targets (pc386, go32 and force386) bsp. Note : this patch is complete only for pc386. It still needs to be completed for go32 and force386. I carrefully checked that anything needed is in for force386 (only some function name changes for IDT manipulation and GDT segment manipulation). But anyway I will not be able to test any of theses targets…
8:04 PM Changeset in rtems [73452854]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Ralf Corsepius <corsepiu@…>: Here is a pure sh-rtems bug-fix patch. The defines to enable the network to host conversion macros in netinet/in.h were missing in sh/cpu.h
7:39 PM Changeset in rtems [613ab62]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Dario Alcocer <alcocer@…> and Ralf Corsepius <corsepiu@…> which attempts to detect when the UNIX port is being configured on a system without System V IPC support. This is an optional component on both FreeBSD and Linux systems. Most Linux 2.x kernels ship with it enabled but it is still a real risk. This test may have undesirable side-effects on some hosts. We will address those conflicts as they arise.
7:32 PM Changeset in rtems [c91e032]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed consolex from build list. This file should be obsoleted by the libchip, libio, and termios efforts.

Jul 21, 1998:

1:59 PM Changeset in rtems [92fc5a5]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Fix from Chris Johns <ccj@…>. Comments: Mask interrupts and save the current USP and MSP for all 68000 processor variants.

Jul 18, 1998:

6:44 PM Changeset in rtems [bced36d]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Changed so we could test interrupts on port 3.
6:35 PM Changeset in rtems [c14a619]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed use of data port for z8530. Move some code around.
6:35 PM Changeset in rtems [3652929e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed use of data port for z8530. Tested all four ports. MC68681 as both polled and interrupt. Z8530 as polled only.
6:34 PM Changeset in rtems [91f16d5]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New file
5:47 PM Changeset in rtems [a4d34dd2]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added z85c30 specific probe routine to decide what the clock rate was. This routines could be enhanced to determine if the SCC is present since it appears from the DY-4 manual that a status registers indicates this.
5:46 PM Changeset in rtems [f8a5d54e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Addresses for SCC were wrong. A and B ports were swapped. Deleted CSS interface related items. Added items required to access DMA Control and Status Register so we could figure out dynamically what the clock speed of the SCC really is.
4:56 PM Changeset in rtems [c53e1df4]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Swapped RX and TX since doing this makes the lights blink on the RS-422 converter. We now see the TD light blink when typing characters in HyperTerminal? and when the board is reset we see the RD light blink. This leads us to believe the cabling is basically right.
4:11 PM Changeset in rtems [fe05ec5e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added RS-422 converter information and cable building information.
3:34 PM Changeset in rtems [cc3d33ac]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added information on the MC68681.
3:24 PM Changeset in rtems [f7d6e57]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added background and setup to add section on RS-422.
3:23 PM Changeset in rtems [f77670be]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Reworked to removed dependency on DY-4 CSS ROM monitor interface.
3:23 PM Changeset in rtems [e286479]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed css_iface.
3:22 PM Changeset in rtems [6d4062f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Removed. We are no longer dependent on DY-4 CSS interface code.
3:19 PM Changeset in rtems [cce1200e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New file.

10:34 PM Changeset in rtems [4555bc1e]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Initialized tty->refcount to 0. When (for whatever reason) malloc() returned a buffer which was not zero-filled, the reference count was not correct. When the application exitted, the "lastClose" handler was not being called to flush the output. This problem had manifested itself on a variety of platforms. The function rtems_termios_dequeue_characters() incorrectly incremented the buffer pointers when it was invoked and there were no characters in the ring buffer. This problem had also manifested itself on a variety of platforms. The symptom was a strange repeating of the data in the transmitter buffer when the transmitter serial device was supposed to go idle.
10:30 PM Changeset in rtems [4fb08fd]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Regenerated.
3:49 PM Changeset in rtems [f95d2b53]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Ralf Corsepius <corsepiu@…>. Comments: * Added support for bsd "install" ($(BSDINSTALL)) to host.cfg.in, i.e. the standard "install" program that most packages (including automake) use. In Makefiles outside of rtems, "install" normally is referenced by $(INSTALL), but rtems already uses $(INSTALL) for install-if-change, hence I used $(BSDINSTALL) instead to keep up backward compatibility. * Removed references to @GREP@ etc. from host.cfg.in, as configure.in doesn't check for them (Minor cleanup). * Added installation flags INST*FLAGS to host.cfg.in, which should replace -m XXXX flags for installation calls. *Changes to gcc.cfg to enable it to build host programs from multiple sources files. Should not disturb existing sources, but neccessary. * There was a not-so-minor bug in the configuration files: "make install" and "make debug_install" don't work in all subdirectories!! I tried to fix this by adding "install" to MTARGETS in main.cfg, which seems to solve most of the problems. But there still seem to be rare (?) cases where "make debug_install" still seems to have problems. * Changes to many host related tool-Makefiles to demonstrate the abilities of INST*FLAGS, BSDINSTALL and the new rules in gcc.cfg. ..of cause ... but BSDINSTALL is THE standard method to install files in most program packages besides rtems. This part of the patch fixes some minor protection setting problems, but doesn't support TARGET_VARIANTS NOTE: I hope you will like the BSDINSTALL, INST*FLAGS stuff. It is a step to get rid of "install-if-change" and to rely on a more standard installation procedure. If you don't like BSDINSTALL, removing it from the patch isn't difficult- just grep for BSDINSTALL and replace BSDINSTALL with INSTALL or MKDIR. FINALLY: I still have another patch pending (well, not a complete patch yet, it's a partial patch to demonstrate the principle), which adds automatic rebuilding of files generated by autoconf/configure. At the moment I don't dare to submit it, because integrating this patch would require to modify all Makefile.ins because we'd need to add a new "include " line to each Makefile.in.
3:43 PM Changeset in rtems [8123c635]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added scitab directory.
3:42 PM Changeset in rtems [a56e475f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Turned stack checker on.
3:19 PM Changeset in rtems [bdba552f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch fromalf Corsepius <corsepiu@…>: * c/src/lib/libbsp/sh/gensh1/scitab - NEW DIRECTORY Location for building the table generated by shgen
3:18 PM Changeset in rtems [9305e52]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Ralf Corsepius <corsepiu@…>. Changes to make/custom/gensh1.cfg. Needed for shgen support
3:17 PM Changeset in rtems [fa21a843]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New files from Ralf Corsepius <corsepiu@…>. His comments: * c/src/exec/score/tools/sh - NEW DIRECTORY - contains shgen Most of it should be self-explanatory. I am a little bit concerned about host-dependent features (getopt, floating point libraries). This shouldn't disturb much now, as this tool should be compileable on all gnu-based hosts and is only applicable for the sh. But in case somebody complains, we may need to add autoconf checks or even restructurize parts of rtems (IMO, rtems needs to be restructurized - remember the "turning rtems upside down" issue).
1:05 PM Changeset in rtems [6e65840]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Patch from Dario Alcocer <alcocer@…>. His comments: Haven't had a chance to do an extensive shake-out of 980710, but it builds just fine on FreeBSD 2.2.5 (after termios is fixed using the attached patch), and the tests run fine. FYI: FreeBSD doesn't support System V IPC out of the box, but one only needs to add three options to the kernel build configuration file, recompile the kernel, and you're ready.

Jul 16, 1998:

12:16 AM Changeset in rtems [16d0e63]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Corrected header files.
12:16 AM Changeset in rtems [a6f441b]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Minor corrections for typos to get it to compile.
12:03 AM Changeset in rtems [dd5d2f04]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Split default baud rate table into its own file. This shrinks the size of the minimum mc68681 driver. The clock speed field can not now be configured as NULL but must instead specify the address of the default table.

Jul 15, 1998:

11:58 PM Changeset in rtems [4a11d8c]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Fixed typo in which last port did not get switched to default register access routines.
11:57 PM Changeset in rtems [849dc107]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Fixed typos.
11:55 PM Changeset in rtems [670d037]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched to usign the default z8530 and mc68681 register access routines.
11:54 PM Changeset in rtems [8414c033]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added default z85c30 register access routines.
11:54 PM Changeset in rtems [cce9322]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>

11:21 PM Changeset in rtems [efaf85fa]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added interrupt mask and interrupt status register bit constants. Added prototype for mc68681_build_imr(), mc68681_process(), and mc68681_enable_interrupts().
11:20 PM Changeset in rtems [49370cd]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added default mc68681 register access routines.
11:20 PM Changeset in rtems [198d851]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched from driver's own buffering to using termios. This eliminated the need for the ringbuffer manipulation in this driver. It should also allow the removal of mc68681_flush. This greatly simplified the interrupt processing. Reworked Interrupt Mask Register handling. Added imr field to the device context. This handling makes sure that the IMR accurately reflects the state of the port in use and its mate. This required the reworking of the mc68681_enable_interrupts() routine to allow for the specification of which interrupt sources were being enabled/disabled. Reworked initialization to reset using port address rather than chip base address. Basically we were always resetting port 0. Added deviceType field which allows for multiple chips of the same class to have the same vector number.
11:15 PM Changeset in rtems [27a66bd]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added information on the deviceType field.

Added SCV64_Get_Interrupt_Enable(). Added proper headers to routines.
9:43 PM Changeset in rtems [d0cff6dc]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added SCV64_Get_Interrupt_Enable().
9:42 PM Changeset in rtems [38e717f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added chip type identifier field. This was necessary because a single interrupt vector can be shared by multiple chips of varying types.
9:40 PM Changeset in rtems [c0573d7]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added comment to remove use of TxBuffer? ring buffer in all libchip drivers. The scheme used in the mc68681 is the one to follow.

Added CSCV64 functions and addresses.
2:04 PM Changeset in rtems [30a3f76]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched from polling to interrupts and in the process added a conditional compilation section which used CONSOLE_USE_INTERRUPTS to switch all ports between interrupt and polled mode.
2:00 PM Changeset in rtems [437b5a7d]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>

1:59 PM Changeset in rtems [25e3f9a]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched CONSOLE_USE_INTERRUPTS to "1" so console would use interrupts. Switched PPC_USE_SPRG to "0" so RTEMS use of sprg would not conflict with any possible sprg usage by the DY-4 ROM monitor.
1:58 PM Changeset in rtems [be8cbbf]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched deviceOutputUsesInterrupts to TRUE so output would be interrupt driven. Redid "mate determination" code to check that the chip base address was the same but the port address was different. Moved mc68681_process and mc68681_build_imr to the bottom of the file so they would not be inlined. Removed the code which forced mc68681_build_imr to always return 0 which resulted in interrupts never being enabled from the chip. Corrected spacing in prototype of mc68681_write_support_int.
1:53 PM Changeset in rtems [e283140c]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Switched to "deviceOutput = TRUE" which made device output use interrupts.
