- reinstalled priority changing, now in sched() and unready()
- reinstalled check on message buffer in sys_call()
- reinstalled check in send masks in sys_call()
- changed do_fork() to get new privilege structure for SYS_PROCs
- removed some processes from boot image---will be dynamically started later
sys_privctl() call to dynamically start servers and drivers.
- Shutdown sequence slightly adjusted: called as watchdog timer to let the
busy sys_abort() call from the PM return first.
- Changed umap_bios() to have more restrictive check: BIOS memory is now
allowed in BIOS_MEM_BEGIN to END (interrupt vectors) and BASE_MEM_TOP
to UPPER_MEM_END. Hopefully this keeps QEMU and Bochs happy.
New configuration header file to include/ exclude functionality.
Extracted privileged features from struct proc and create new struct priv.
Renamed various system calls for readability.
and the new log driver if enabled.
new usyslogd is started from /usr/etc/rc. New device created by
MAKEDEV.sh. /var/log created by etc/mtree/minix.tree (on root for
now). Made select() slightly more generic, with less code duplication.
- current and maximum priority per process;
- quantum size and current ticks left per process;
- max number of full quantums in a row allow
(otherwise current priority is decremented)
Removed stop sequence when MINIX is shut down.
Disabled send mask checks --- to be replaced by proper mechanism.
Fixed bug relating to 'shutdown -x'.
Simplified clock accounting of realtime.
Updated Makefiles for mkdept script.
