Ben Gras 629453fba8 Added explanation of SIGKILL, REBOOT order. 2005-10-21 11:10:16 +00:00
Ben Gras 5333d4f4e4 . don't kill tty, send it messages on signals 
. kill processes first, then tell fs to reboot (otherwise fs will have
  exited its processes and be confused when they exit again)

IS: prints out hole list + stats such as largest contiguous chunk
 2005-10-13 12:48:43 +00:00
Jorrit Herder 5a9dec8bd2 New signal handling behaviour at PM (services can be killed). 
New Shift-F6 dump for RS server at IS.
New getnpid, getnproc, getpproc library calls at PM.

Various updates to support dynamically starting servers and suppress output.

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
Ben Gras 9cf24c3233 Calls and functionality for get/setpriority() and fsync(). 2005-07-01 17:58:29 +00:00
Jorrit Herder 042c4ac395 Changed Makefiles for mkdep script. 
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
Jorrit Herder 92f9bd02f8 Parsing of free memory chunks is now done at the process manager. 2005-06-17 09:10:30 +00:00
Jorrit Herder 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.
 2005-06-07 14:43:35 +00:00
Jorrit Herder 2f74381dcc Fixed 'ps' utility: now get process table addresses with getsysinfo() calls. 
To be done: get copies of process tables instead of using /dev/(k)mem.
 2005-06-06 13:51:50 +00:00
Jorrit Herder 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.
 2005-06-03 13:55:06 +00:00
Jorrit Herder e782e76944 Created new findproc system call to the PM (to replace similar kernel 
functionality). Currently working on memory allocation (not yet finished).
 2005-06-02 12:43:21 +00:00
Jorrit Herder 9646824fce Fixed PM send() failed warning: don't reply to killed process that did reboot. 
:  `VS: Enter Log.  Lines beginning with `CVS:' are removed automatically
 2005-05-30 09:29:48 +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.
 2005-05-27 13:10:58 +00:00
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.
