* Large patch from Erik Ivanenko <erik.ivanenko@utoronto.ca> whichJoel Sherrill1998-10-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Patch from Aleksey (Quality Quorum <qqi@world.std.com>):Joel Sherrill1998-09-231-12/+2
| | | | | | | | | | | 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.
* Patches from Aleksey which were not in 980911.Joel Sherrill1998-09-211-1/+4
| | | | | | 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.
* Update from Eric Valette <valette@crf.canon.fr>:Joel Sherrill1998-09-211-3/+6
| | | | | | 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.
* Patch from Emmanuel Raguet <raguet@crf.canon.fr>:Joel Sherrill1998-09-101-0/+6
| | | | | | | | | 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.
* Patch from Eric Valette <valette@crf.canon.fr>:Joel Sherrill1998-08-211-2/+5
| | | | | | | | | | Here is a patch that enables to catch exception and get message before crashing RTEMS :) It should be generic to any Intel port although enabled only for pc386 BSP... [Joel] I fixed the bug I introduced in irq_asm.s...
* Patch from Aleksey <qqi@world.std.com>:Joel Sherrill1998-08-191-4/+45
| | | | | | | | | | | | This patch has same changes as one I sent to you earlier plus it fixes _heap_size problem for pc386 we had discussed earlier. Now, _heap_size is defined and set to 0 in pc386/startup/bspstart.c It can be patched to desireable value in binary image. If it is left unpatched, then startup code will determine size of memory (on the assumption that at least 2MB are present) and use max possible heap.
* Automatic CPU type detection code from Eric Valette <valette@crf.canon.fr>.Joel Sherrill1998-08-051-2/+4
| | | | Enabled on the pc386.
* Patch from Eric VALETTE <valette@crf.canon.fr>:Joel Sherrill1998-07-231-1/+7
| | | | | | | | | | | | | 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...

* Numerous changes including the following:Joel Sherrill1998-05-271-2/+26
| | | | | | | | | | | | + 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.
* Update from Pedro Romano <pmcnr@camoes.rnl.ist.utl.pt>.Joel Sherrill1998-04-271-9/+12

* Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1998-04-151-25/+0
| | | | | | | | | | | | code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
* Transitioned to shared bsp_libc_init() and cleaned up comments.Joel Sherrill1998-04-151-42/+9
|
* Per suggestion from Eric Norum, went from one initial extension setJoel Sherrill1998-04-151-12/+0
| | | | | | to multiple. This lets the stack check extension be installed at system initialization time and avoids the BSP having to even know about its existence.
* Stack checker extension now accounted for in confdefs.hJoel Sherrill1998-04-141-6/+0
|
* Now accounts for region used by RTEMS malloc and extension usedJoel Sherrill1998-04-141-10/+0
| | | | by newlib.
* Moved bsp_postdriver_hook() to a shared file and made it a commonJoel Sherrill1998-03-301-33/+4
| | | | component.
* Switch to using a shared main() for all of the embedded BSPsJoel Sherrill1998-03-211-9/+6
| | | | | | | | based on the GNU tools. This usually involved correcting the type of bsp_start(), bsp_cleanup(), adjusting the start code to call the right start routine (the shared boot_card()), and then removing code from bsp_start() which was performed in the new boot_card()/main() path.

I try to keep w\up with it. Now that you have asked -- I'll attach a list of files lacking an RCS-Id to this mail. This list has been generated by a little sh-script I'll also enclose.
