Jorrit Herder 0165662cd9 Replaced flagalrm() timers with another technique to check for timeouts.
This allowed removing the p_flagarlm timer from the kernel's process table.
Furthermore, I merged p_syncalrm and p_signalrm into p_alarm_timer to save
even more space. Note that processes can no longer have both a signal and
synchronous alarm timer outstanding as of now.

Jorrit Herder 322ec9ef8b Moved stime, time, times POSIX calls from FS to PM. Removed child time
accounting from kernel (now in PM).  Large amount of files in this commit
is due to system time problems during development.

Jorrit Herder 852008d669 Kinfo counts lock_notify() and lock_send() calls. 2005-05-27 14:54:40 +00:00
Jorrit Herder 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.

Jorrit Herder 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.

Jorrit Herder 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.

Jorrit Herder 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.

Jorrit Herder 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.
