| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

| | | | | | | | | | | 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.

| | | | | | | | | | | I have managed to build the bsp ods68302 and the rtti test case I made with egcs-1.1b and binutils-2.9.1. I have built our C++ application and got no link errors so it looks like this is now working. I am yet to test the code but getting the thing to link was the problem. Please find a patch attached which removes the -fno-rtti option.
* 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.

This patch fixes the two problems mentionned above + it use vpath mechanism intead of copying the irq related files in the right directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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...

| | | | | | | | | | | | | | I think I figured out why rtems_panic was locking up instead of shutting down the executive and returning to the code that called boot_card(). Later on there is code to print some messages on the standard error stream, a recursive call back to rtems_verror (through rtems_error) and finally a call to _exit(). I think that the _Thread_Disable_dispatch() is preventing the final context switch back to the boot_card() code. Does this sound right to you?

| | | | | | | | | | | | | | | | 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).

Yes, there's a bug there. I thought that Joel had patched this already, but here's a patch to fix this. This patch also addresses a concern that many others have raised regarding enabling and disabling of transmitter interrupts. First, here's the example I've been using of a simple UART-style interrupt-driven driver: =============================================================== void device_write_routine (int minor, char *buf, int count) { UART->control_register &= ~UART_TRANSMITTER_READY; UART->output_register = *buf; UART->control_register |= UART_TRANSMIT_INTERRUPT_ENABLE; } void device_transmit_interrupt_routine (int vector) { UART->control_register &= ~UART_TRANSMIT_INTERRUPT_ENABLE; rtems_termios_dequeue_characters (device_ttyp, 1); } ============================================================== Several people have expressed their concern about the disable/enable of transmitter interrupts for every character. On some machines this disable/enable is an expensive operation. With the attached patch applied you can write the two routines as: ============================================================== void device_write_routine (int minor, char *buf, int count) { code_to_clear_transmitter_ready_status (); if (device_ttyp->rawOutBufState == rob_idle) code_to_enable_transmitter_interrupts (); code_to_send_one_character_to_transmitter (*buf); } void device_transmit_interrupt_routine (int vector) { rtems_termios_dequeue_characters (device_ttyp, 1); if (device_ttyp->rawOutBufState == rob_idle) code_to_disable_transmitter_interrupts (); } ===============================================================
