Used shared sbrk.c.
10:41 AM Changeset in rtems [825a2bb]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Use shared initialization.
10:32 AM Changeset in rtems [55b517c]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Rewrote in C to avoid Makefile problems.
10:17 AM Changeset in rtems [9c559acc]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New file -- from rtems-LM-980406 based on a 12/97 RTEMS snapshot.
10:09 AM Changeset in rtems [c932d85]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
New files -- from rtems-LM-980406 which was based on an RTEMS from 12/97. This was called the dmv170 BSP in that source tree but since the DMV171 is now obsolete, we have transitioned to the DMV177 and have no intention of checking compatibility with any other models.

Deleted blank lines.
10:09 PM Changeset in rtems [bb6d368]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Added "speaker on" debug code.

7:34 PM Changeset in rtems [4050a7f]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Numerous changes including the following: + DEBUG_EARLY_START re-added (Eric Valette) + segment register initialization (Aleksey/Quality? Quorum) + heap size use correction + more debug printk's + increased heap size. Now works with grub boot on all systems I have access to including desktops and a laptop. This is with the i386-rtems tools. Neither i386-rtemself nor netboot produces a working executable.

Fixed spacing
12:21 PM Changeset in rtems [139e6efe]4.104.114.84.9 by Joel Sherrill <joel.sherrill@…>
Fix from Jiri Gaisler <jgais@…> for a problem in which external interrupt priorities were not being honored. Here is some of his original report: using rtems/erc32, I have a problem with interrupt priority when interrupts occure simultaneously. Erc32 has an interrupt force register where interrupts can be generated. If more than one interrupt is generated, the interrupt handlers are scheduled in the wrong order, i.e. with the lowest priority first. I have attched a program that generates three interrupts, 0x11, 0x12 and 0x13. Interrupt 0x13 should be handled first, but is actually handled last. Below is the output from sis: sis> go resuming at 0x02000000 RAM size: 4096 K, ROM size: 2048 K Watchdog disabled Waitstates = RAM read: 0, RAM write: 0, ROM read: 0, ROM write: 0 Power-down mode enabled infinite UART baudrate External interrupt received with vector 0x11 External interrupt received with vector 0x12 External interrupt received with vector 0x13 I have verified that sis generates the interrupts in the correct order, i.e. 0x13 first, then 0x12 and then 0x11. So the problem seems to be in the rtems interrupt handler. Do you use the PIL field in the %psr register to mask lower priority interrupts or are all external interrupts considered to have the same priority ..? Here is a description of the fix: it turned out that lower priority interrupts were not at all masked off during interrupt handling. I made the following fix to cpu_asm.s: ... fix is in the code ... There might be a simpler way of doing this, but this works…
