Jorrit Herder 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.
2005-08-04 19:23:03 +00:00
Jorrit Herder 3f28baac83 Disabled comments from FXP driver with #define VERBOSE 0.
Fixed all troubles reported at shutdown.
No more illegal FS calls by dead processes.
2005-08-03 16:58:22 +00:00
Jorrit Herder 89cf745fe2 Single boot driver loaded, while multiple can be included in the boot image.
The user needs to set label=... to choose the driver of his or her choice.
This driver will be mapped onto the controller that is set in controller=...

Minor cleanup of kernel source code (boot image table now is static).
2005-08-03 16:06:35 +00:00
Jorrit Herder 1ae4d41d0d Without /dev/boot ... 2005-08-03 14:17:28 +00:00
Jorrit Herder 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.
2005-08-03 08:14:08 +00:00
Jorrit Herder 0bd61375ad Miscellaneous small fixes to prettify startup output. 2005-08-02 15:56:24 +00:00

. Allow 'boot monitor' variable changes and additions by svrctl call
2005-07-22 18:29:58 +00:00
Jorrit Herder 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.
2005-07-20 15:27:42 +00:00
Jorrit Herder 5594b767c0 Renamed src/lib/utils to src/lib/sysutil --- because of new src/lib/util 2005-07-19 13:21:51 +00:00
Jorrit Herder 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.
2005-07-19 12:11:11 +00:00
Jorrit Herder eba45510a9 New alarm(2) timers mechanism.
Kernel no longer keeps track of user alarms on behalf of the PM.
Instead, the PM maintains its own list of watchdog timers, and
uses one synchronous alarm (at the kernel) to get notifications
for expired user timers.
2005-07-14 15:30:12 +00:00
Jorrit Herder 570eac1f53 Renamed system library functionality.
Updated debug dumps of IS server.
2005-07-14 15:16:12 +00:00
Ben Gras f0817fbd4c complete, tick-resolution gettimeofday() implementation 2005-07-06 07:08:36 +00:00
Ben Gras 904cf1f84d A "fix" for bug no. 2 is to check if the process slot has disappeared.
Not a really good solution (as it might not catch situations in which this
is caused by another bug), but the forrest of checks necessary might be worse
than this quick fix - because when looking for the cause, I found some other
cases in which the PM would panic as well. See info in bug 2 for details.

Another fix is to delay notification of PM by SYSTASK of signals delivered
internally until after the reply (e.g. of exec()), because the reply would
be messed up otherwise (receiving the notify instead of reply). This caused
SIGTRAP not to be delivered properly with traced processes.
2005-07-04 15:20:46 +00:00
Ben Gras 08f67dcef7 . Added printing of ppid to PM dump output
. made PM pid 0, own parent (so ppid 0) instead of -1
2005-07-04 09:36:16 +00:00
Ben Gras 9cf24c3233 Calls and functionality for get/setpriority() and fsync(). 2005-07-01 17:58:29 +00:00

Updated debugging dumps at IS server, and function key control.

NOTE: pm modified with DEBUG() output, to be removed later.
2005-06-24 16:21:21 +00:00
Ben Gras c9c6983cc1 Fixed a few quirks in misc.c
. MAX used where it should've been MIN
  . buffer byte too short
  . inobvious use of & with && without parantheses
  . funny length checking
2005-06-20 09:35:23 +00:00
Ben Gras 45ddea1cdd Fixed bug that caused the PM to brutalize the contents of the 'memory'
variable. Parsing worked, but future requests for the variable (such as
by the sysenv command) returned truncated data. This caused the system
(e.g. setup script) to think the amount of memory was tiny, and caused
the enabling of swapspace, while it is unnecessary.
2005-06-19 23:16:08 +00:00
Jorrit Herder 92f9bd02f8 Parsing of free memory chunks is now done at the process manager. 2005-06-17 09:10:30 +00:00
