* Patch from Aleksey (Quality Quorum <qqi@world.std.com>):Joel Sherrill1998-09-232-4/+10
| | | | | | | | | | | 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'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.

This patch fixes the two problems mentionned above + it use vpath mechanism intead of copying the irq related files in the right directory. This avoid to compile them each time and is more homogenous with other Makefiles.

| | | | | | | | | | | | | | 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?

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 (); } ===============================================================

It looks like BSDINSTALL is not defined properly. BSDINSTALL is defined in make/host.cfg.in as BSDINSTALL=@INSTALL@ @INSTALL@ is generated by autoconf's standard macro AC_PROG_INSTALL, which is widely used in almost any autoconf/automake configured package. In case there is really something wrong with it, then it must be considered a bug in autoconf. I can see a doubious fragment in AC_PROG_INSTALL, which is used when no appropriate bsd-install is found. Finally Ralf saw a problem with the find on solaris which I also saw and fixed.

* Patch from Chris Johns <ccj@acm.org>. Comments follow:Joel Sherrill1998-08-131-0/+19
| | | | | | | | | | | Here is a small patch which allows the m68060 to be used. I have not tested the FP switching stuff which we know is broken. This is taken against the libchip snapshot but should merge without problems. If you have any problems please let me know. There are other smaller issues such as superscalar enable and cache control which I have not addressed yet. They are different to all other m68k processors. These can wait IMO.
