moves pieces of the pc386 bsp up to a shared level for all i386 BSPs
and modifies the i386ex BSP to use those shared pieces. Serial remote
debugging is included for both targets. Erik's notes:
There are several workarounds in it:
1) #define NEXT_GAS is hardcoded in pc386/start/start.s
2) #define NEXT_GAS is hardcoded in i386ex/start/start.s
3) #define NEW_GAS is hardcoded in pc386/start16.s
4) #undef __assert and redeclare _assert hardcoded in console.c for
both pc386 and i386ex due to my egcs1.1b ~ newlib problem. Should have
modified t-rtems.cfg ( no time )
I've tested pc386 with both video and serial consoles and GDB remote.
All work fine, except that GDB acts weird. ( re: other posting)
I hope this will work for you. It took quite some time to locate the
autoconf error. The remainder was just grunt work.
Unfortunately, I think I've unwound the removal of the IBMPCInitVideo
stuff. Sorry. I REALLY can't spend more time... I've been at this
conversion to 4.0 locally and updating the release since Sept. 8th, and
have yet to compile my network driver.... This is as much as I can do
right now.
I look forward to the next patch to really test i368ex. I did make sure
that the sample tests worked for pc386.

The reentrant versions of the malloc functions in
c/src/lib/libc/malloc.c
do not match the definitions in newlib. These will be used if you use
newlib routines such as fdopen. I believe this patch to malloc.c is
needed to provide the correct versions.

Finally I am through: I have found the last bugs that made RTEMS-
4.0-beta3 start on my ppc403 board from ROM. So now the '403
support is up to date again.
Roughly I have added the following features:
- support for the on-chip interrupt controller (in a separate module)
- interrupt support for the console device
- termios support for the console device
==============================================
Since the BSP behaivour changed in some details (console no
longer is polling, other memory layout etc) I have created a new
BSP "helas403" rather than changing the "papyrus" BSP. The old
"polled" console driver still sticks around in "console.c.polled"
To get the BSP up and running, I had to create the new BSP files
(derived from papyrus). Besides that, the following source areas
have been changed:
- c/src/lib/libcpu/powerpc/ppc403: changes to console driver, small
changes to clock driver, new "ictrl" interrupt controller driver
- c/src/exec/score/cpu/powerpc/ppc.h: some small changes
(added ppc403 characteristics like a exception vector prefix
register, some special register definitions). I am quite sure, they
are compatible with the existing sources, although I did not check
- c/src/exec/score/cpu/powerpc/cpu.c: There is one severe
limitation in the exception entries: Due to the current code
arrangement, the "branch absolute" to the ISR handler may only
jump to the first 128MByte or the last 128MByte of the 4GByte
address range. When the ppc403 is running out of ROM, the ROM
functions are located in the last 128MByte (0xFFF00000 and up).
These addresses were not handled correctly (sign reduced) in
"install_raw_handler". The change I added should work on existing
ppc BSPs aswell...
- c/src/lib/libc/termios.c: During my tests, I added one change you
sent me, so this patch will already be incorporated in the current
source tree.
There are some smaller changes, see the attached diff file.
=========================================
Concerning the GNU toolchain:
I tried several tool chains. Finally I almost succeeded with
egcs-1.0.3a with patch egcs-1.0.3-rtems-diff-19980527
I had to add the following lines to the egcs files. Without them
configure complaint that the cross compiler could not generate
executable output.
- additional lines needed in egcs distribution in file
gcc/config/rs6000/rtems.h:
+++ lines start
#undef STARTFILE_DEFAULT_SPEC
#define STARTFILE_DEFAULT_SPEC "ecrti.o%s"
#undef ENDFILE_DEFAULT_SPEC
#define ENDFILE_DEFAULT_SPEC "ecrtn.o%s"
++++ lines end
As far as I have seen in the Changelog of egcs, you have recently
sent two patches affecting the powerpc support, but they were
added in the wrong order.... :-(
egcs-19980628 with patch egcs-19980628-rtems-diff-19980707 does
not work!
I used binutils 2.9.1 with patch binutils-2.9.1-rtems-diff-19980515
(binutils 2.8.1 does not work, internal error in gas)
and newlib-1.8.0 with patch newlib-1.8.0-rtems-diff-19980707
Finally I had to poke a line in the "bit" script, since, on my LINUX
machine, the GNU make is only available as "make", not as
"gmake"...
For all the tools and newlib I selected configuration "powerpc-
rtems".

The pc386 linker scripts omits .gnu.linkonce.r* sections. It's not a
big deal, but they should be treated like .rodata sections. ELF
versions of g++ generate them for static constants defined in template
classes, such as string::npos.

Please find enclosed a patch which enables me to build the bare-bsp for
sh-rtems.
Changes:
1. Add preinstall to libbsp/bare/include/Makefile.in
2. Removed FORCEIT, add preinstall to
libbsp/sh/gensh1/include/Makefile.in
3. Disabled support of set_vector from sh code (shared/setvec.c is still
present but isn't used anymore), set_vector replaced with standard rtems
functions.
Problems still present:
1. Support of spin-delays in bare bsp
2. Proper support of cpu frequency
To configure I used:
<srcdir>/configure \
--target=sh-rtems \
--prefix=<instdir>/sh-bare \
--enable-bare-cpu-model=sh7032 \
--enable-bare-cpu-cflags='-Wall -m1 -DMHZ=20
-DCPU_CONSOLE_DEVNAME="\"/dev/null\""'
--enable-rtemsbsp=bare \
--disable-networking \
--disable-cxx \
--disable-posix \
--disable-tests
IMO, if there are no objections to this patch, a similar approach should
be applied to all CPUs/BSPs (esp. hppa1.1, mips64orion, ppc403, because
they apply set_vector inside of libcpu).

Remember the test to see if a socket could be read and written at
the same time by two different tasks? I discovered that if both
tasks attempt to close the socket a panic can occur from inside the
BSD code.
Closing the same socket twice from two different threads is
certainly an error, but a panic is not the greatest error reporting
method :-)
The following small change to the socket close routine should reduce
the chances of the panic.

Please find attached a start.s that includes a cli prior to the hlt
instruction. This ensures that external interrupts cannot restart
the system after returning to the startup code. ( According to the hlt
docs, they will! )
Also find a new timer.c. ( I forgot to update the countdowm value
in the timer when I changed the PSCLK frequency in start.s) . This
improves timer accuracy.
The raw_idt_notify messages are no longer infinite, I tested sp11 and
sp05, both which were bad, and I have seen the message print once in
one test. I think it's ok if it prints out once. In fact, I don't
think you can effectively stop it!

Please find attached the two files that have been changed relative to
980921 . The changes here are in the handling of the counter-timer used
as the basis for the rtems executive clock. For the most part, these
are housekeeping changes.
The PSCLK frequency change in start.s... was a part of several
bug-fixes. The fix improves executive clock and timer accuracy.
changes :
start.s -- All timers are disabled by the initialization routine
-- PSCLK ( used by clock and timers ) frequency changed to 1MHz
The clock_initialize routine now assumes that the PSCLK frequency is
exactly 1 MHz.
ckinit.c
Clock_isr -- removed division by 1000. Now use 'static'
variable -- clock_intial_isr_value -- to reset Clock_isrs variable.
clock_initialize -- moved counter timer initialization here. Values
used to configure the timer are totally dependent on
BSP_configuration.microseconds_per_tick ( and the PSCLK assumption).
Initializes clock_initial_isr_value used by th Clock_isr to reset
Clock_isrs.
clock_on -- no longer configures the timer, just enables it.
Since altering the number of sections in the BSP, I decided to give it a
good "once over" . The clock handling is now cleaner.

1. Finally fixes raw interrupts for pc386
2. Makes some minor cleanup in console and startup
3. Makes rtems_termios_dequeue_characters() to return count of
outstanding chars - it allows to simplify console isrs a little
bit.
4. pc386 uart modified to be friendlier to termios parameter changes,
to have minor performance improvement and to take advantage of
of above termios modification.

Here's a patch to make the rtems_showroute routine a little more
useful. For `host' route table entries the link-level address is now
displayed. This is equivalent to the old `show arp table'
information displayed by the KA9Q code.

I am sending you patch which was lost. As far as I remember there
were minor patches on top of it, either by Eric Valette or
by Eric Norum or by both.
|
|
|
|

Here are patches that bring 980911 back to what I think is a correct
version of raw IDT management as well as a correct initialisation
of video console and rtems managed interrupts.

I fixed the problems noted by Victor Vengerov.

2) In rtems_termios_open, ensure that args->iop->data1 is set before calling
device-specific open routine.

I've fixed a few minor probs with the optimised version that Eric put
together for me the other day and sent the fixes back to him. Provided he
doesn't have a problem with it we've got a pretty solid in_cksum for the
ColdFire as well as straight m68k. I've enclosed my updated in_cksum_m68k.c
At the moment my own bottlenecks are elsewhere...as my driver is pulling
16bit data chunks through a libchip-esq access routine from the chip which
for a polled I/O device is never going to be quick.

patch_com2 was before your own fixes of raw IDT vector management
routine.
It mainly use human readable constants for the serial line driver code
+ the patch you gave me for com2 write routine.
I applied your patch for raw IDT mngt on top of that. Then made minor
cleaning in patch_idt_mngt. I hope this helps.

After some good comments from Eric Norum [thanks, Eric !],
I have added some modifications to my previous driver patch :
- wait for transmitter ready before sending a packet,
- new delay management in case of ring-overwritting.
