d0b5cf84cb Undid usage of vector-copy function. It's a good idea but there's a bug 
there somewhere. I'll debug first, then recommit.

e782e76944 Created new findproc system call to the PM (to replace similar kernel 
functionality). Currently working on memory allocation (not yet finished).

f926f1209d Minor commit to remove conflict with update. 2005-06-01 14:34:59 +00:00

6d23f072f3 Cleaned up src/lib/utils library. Renamed server_ functions to more logical 
names. All system processes can now either use panic() or report() from
libutils, or redefine their own function. Assertions are done via the standard
<assert.h> functionality.

447b988154 exec now uses phys_zero system call to zero bss segments (instead of 
using phys_copy to copy zeroes there for every kb), which is a big
optimisation in some cases

fixed a bug that was introduced when function keys became notifies

a3d2f35993 Fixed minor bug in PM's child time administration. 2005-06-01 08:55:22 +00:00
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.

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.

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.

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.

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.

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.
