b421423c77 SENDREC now always has flag FRESH_ANSWER to prevent pending notifications 
to be used as answer to a SENDREC call.

826fee4c6d Fixed clear_proc(): properly release resources (IRQ hooks, notify buffers); 
Cleaned up comments in proc.c (old code still present for comparison);

07d582872f Fixed a bug in PM: sending of reply messages didn't check if destination 
process is still alive. This caused a panic in some situations, e.g., when
all processes are killed on a shutdown.

c2be104821 Improved NOTIFY system: fixed a minor error, ignore pending notifications 
on SENDREC system calls. To be done: resource (buffer pool) management;
make it structurally impossible to run out of buffers.

77c3213948 Optimized scheduling code. Old code is still available withing DEAD_CODE 
and NEW_SCHED_Q definitions. Some minor problems are being traced at the
moment. This commit is meant to backup my files.

dcffa17db2 this test breaks on the new pre-i/o i/o buffer check. it wants to read 
more than its buffer allowed, so it is reasonable that it breaks. reducing
read request size 'fixes' it.

6a3519f3a8 Added 2 checks to mapping function - one for overflow (virtual address + 
size wraparound), one to see if the size fits in the designated segment.

It seems this check wasn't done. This came to light when trying to pre-check
the users buffer for read() and write() in using the vectored virtual
copy system call in servers/fs/read.c.

ccd17ecfed New NOTIFY system call! Queued at kernel. Duplicate messages (with same source 
and type) are overwritten with newer flags/ arguments. The interface from
within the kernel is lock_notify(). User processes can make a system call with
notify(). NOTIFY fully replaces the old notification mechanism.

64ecaca24b Changed something in default no. of inodes in mkfs (I run out of inodes 
often with the defaults).

Made setup script not make root filesystem with 1kB filesystem blocks,
as that restriction is out of the boot monitor now.

f8bd2691ec Removed root filesystem blocksize restriction by reducing boot monitor 
stack size from 16kB to 8kB. No apparent adverse affects.

cff515edd8 made time use times() system call to get higher resolution (1/60s clock 
ticks instead of 1s) for real time measurement.

307c825515 New NOTIFY trap (IPC call) to send queued notification messages. 
The call works. Permission check, restriction of outstanding notifications
to be added. Low level code to make it work from within interrupt handlers
will be added as well.

e248f7c1a3 If the file (created by setup) exists, use boot parameters from there 
for the boot floppy instead of copying it from the current root partition.
This makes making a boot floppy at installation time before booting from
the new system possible (conveniently).

6f9848f51c Added feature to remember root parameter in /usr/src/tools, so make fdboot 
will know how to make a boot floppy before actually booting from the new
system.

873e44b41f Some #defines for removing registered irq handler 2005-05-12 16:07:15 +00:00
Ben Gras
d0c3e8f818 . added rm_irq_handler which un-links an irq handler from the linked 
list of handlers, callable by irqctl system call
 . workaround for hanging keyboard bug after shutdown.. if key is pressed
   during or after shutdown procedure, keyboard stops working. It looks like
   irq 1 gets stuck high if no keyboard reading is done (e.g. because the
   irq is masked or tty driver has exited). Workaround is to leave irqs
   enabled until the last second, and call shutdown() immediately after the
   last driver has stopped (tty task). This way the chance of an unserviced
   interrupt occuring is negligible.
