872687ddfc Scheduling updates to the kernel. Sched() function now is single point for 
policy. Actual policy not yet implemented.

PM calculates nice values for processes in boot image.

IS debug dumps improved (Shift+F1-F4).

a01645b788 New scheduling code in kernel. Work in progress. 
Round-robin within one priority queue works fine.
Ageing algorithm to be done.

74711a3b14 Check if kernel calls is allowed (from process' call mask) added. Not yet 
enforced. If a call is denied, this will be kprinted. Please report any such
errors, so that I can adjust the mask before returning errors instead of
warnings.

Wrote CMOS driver. All CMOS code from FS has been removed. Currently the
driver only supports get time calls. Set time is left out as an exercise
for the book readers ... startup scripts were updated because the CMOS driver
is needed early on. (IS got same treatment.) Don't forget to run MAKEDEV cmos
in /dev/, otherwise the driver cannot be loaded.

b69ca94efb Fixed 'bug' in log driver that caused kernel messages not to be displayed. 
This was caused by a change in the shared driver code. Not log's fault.

Renamed #definitions of driver process numbers, e.g., TTY now is TTY_PROC_NR.
All known (special) processes now have consistent naming scheme. Kernel tasks
don't follow this scheme.

f44725b777 Created new devctl system call to FS. Moved dmap.h header to include/minix/.

d62e515660 Small update to SYS_IRQCTL -> setting an interrupt policy now allows the caller 
to provide an index (0 .. 31) that is passed in the HARD_INT message when an
interrupt occurs. The NOTIFY_ARG field contains a bitmap with all indexes for
which an interrupt occured.

f1153541c7 Fixed bug in PM that caused update program not to be scheduled, so that 
sync was not periodically run. Chain of timers was accidentially broken.

Kernel sends SIGKSTOP signal on shutdown. FS calls sync to clean up.

f2e16763e7 Removed PM signon for INET. Now daemonized in /usr/etc/rc. 
SIGTRAP generated in PM (where it belongs / no longer in kernel).
Updated Makefiles: servers are now installed in /usr/sbin.

42050e39f8 kernel and servers send diagnostic messages to IS; IS sends them to TTY 
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.

ec24a0798c Updated function key mapping because of possible changes to NOTIFY. 
The TTY driver now only notifies the IS server about function key event,
but does not tell which keys are pressed. The IS servers queries the TTY
driver to find out about this.

c2cd510adf Removed debug dumps from the PM and FS servers. The dumps are now done by the 
IS servers, which obtains a copy of the data through the getsysinfo() system
call. CTRL-F1 now is a special TTY key to shows function key mappings.

f2a85e58d9 Various updates. 
* Removed some variants of the SYS_GETINFO calls from the kernel;
  replaced them with new PM and utils libary functionality. Fixed
  bugs in utils library that used old get_kenv() variant.
* Implemented a buffer in the kernel to gather random data.
  Memory driver periodically checks this for /dev/random.
  A better random algorithm can now be implemented in the driver.
  Removed SYS_RANDOM; the SYS_GETINFO call is used instead.
* Remove SYS_KMALLOC from the kernel. Memory allocation can now
  be done at the process manager with new 'other' library functions.

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.

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.

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.
