* Update of network driver from Erik Ivanenko <erik.ivanenko@utoronto.ca>.Joel Sherrill1999-01-206-165/+399
| | | | | | | | | | | Comments follow: Here is the contents of the network directory of the i386ex BSP. The reset function has been recently added, and tested through a command line interface. A reset event to the reset thread to reset the NIC. This is done when the ISR detects that the NIC is in an invalid state. It has not been tested "in real life" since the board has not seen an invalid state since the reset function was implemented.

I'd like to propose to remove these flags from the files mentioned above.

* Patch from Ian Lance Taylor <ian@airs.com>:Joel Sherrill1998-10-281-8/+60
| | | | | | | | | | | | | | | The RTEMS i386 stub in c/src/lib/libbsp/i386/shared/comm/i386-stub.c doesn't take advantage of some of the newer gdb remote features which permits shorter and fewer packets. Here is a patch which uses the 'T' response to report the registers which gdb generally needs, and implements the 'P' request to set only a single register. The general effect is to avoid sending all the register contents back and forth between gdb and the stub every time the stub stops. This also implements the 'D' request which handles the gdb detach command, so you can cleanly quit out of the debugger and leave the target board running.

* Patch from Ian Lance Taylor <ian@airs.com>:Joel Sherrill1998-10-221-0/+1
| | | | | | | | | I noticed that in the 4.0.0-beta4a tar file, the file c/src/lib/libbsp/i386/pc386/startup/linkcmds was changed so that it no longer handles the .gnu.linkonce.r* sections. The appended patch was applied to the file. I'm not sure why. I think this patch should probably be backed out, although it's not critical for the release.

* Large patch from Erik Ivanenko <erik.ivanenko@utoronto.ca> whichJoel Sherrill1998-10-0531-376/+3515
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Changed based on patch from pc386 linkcmds from Ian Lance TaylorJoel Sherrill1998-09-301-1/+1
| | | | | | | | | <ian@airs.com>: 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 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.
* Patch from Aleksey (Quality Quorum <qqi@world.std.com>):Joel Sherrill1998-09-236-57/+54
| | | | | | | | | | | 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.

| | | | | | 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 Sherrill1998-09-214-16/+16
| | | | | | 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 Eric Valette <valette@crf.canon.fr>. Most of this was includedJoel Sherrill1998-09-101-1/+8
| | | | | | | | | | | | in a previous patch. Comments from Eric: 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a brief description of the attached patch : 1) There was a bug in the code for the COM2 serial line driver. Aleksey gave me a fix that fixes the driver code itself. I would like to thank him again publicly, 2) I introduced constants in the serial driver code because I had a hard time reading the meanning of hexadecimal values in the NS data book :) 3)You can now mix printk and printf on serial line (tested on COM2). There is a #ifdef PRINTK_ON_SERIAL in console.c that enables to have printk on console while printf on serial line, 4) Removed call to displayCpuInfo because anyway if was at the wrong place for serial line console (too early). It can anyway be called at application level, 5) The original printk was unable to display negative integer values and was also recursive. It now works corectly, All the modifications have been tested here on the COM2 port from a PC running RTEMS to a PC running linux, NB : there is still a bug on PC386 serial line : exit does not flush the remaining output queue. As this is not a bug in the driver itself but somewhere in PC386 initialization/termios relationship it will be part of another patch. NB2 : As Emmanuel excerced the exception hanlder code, while porting the SMC driver to the new BSD stack, we found a bug in the exception handler : it shall not delete the current thread in case we are running at interrupt level. This will be part of another patch...

| | | | | | | | | | | | | | | | Celso Labinaz <labinaz@tin.it> pointed to me thatthe console on serial line was not working. After spending quite a time to find the right cable and software, I confirm this. I'm going to debug this in the next days because I want to use the serial line for debugging. In the meantime, in order to be sure that this was a driver initialization/bug, I made printk work on the serial line in order to be sure the receiver part and configuration was OK. Here is the for printk on serial line. BTW, does anyone else use the serial line facilities for PC? printf seems to output nothing (hello.exe output everything that has a printk but application printf seems to be broken).
