c9ab8cce43 Changed minor number of /dev/zero from 6 to 5. 
(Make sure to update your system accordingly or /dev/zero won't work.)
Cleaned up comments in MEMORY driver.

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.

e561081545 Miscellaneous clean ups and fixes to the kernel. 
Support for FLOPPY in boot image. (Set controller=fd at boot monitor.)
Moved major device numbers to <minix/dmap.h> (maybe rename to dev.h?)

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).

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.

Renamed SYS_SETPRIORITY to SYS_NICE.

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.

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.

e44e9ad261 small compile fixes; initial select() stubs; release.sh script doesn't 
need /tmp any more since 16MB root device; increase to 3.0.5 to make new
CD with working FXP driver. (not tagged 3.0.5 yet as at driver bios-copy
workaround hasn't been done.)

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

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

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.

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.

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.

0899f82ab2 Fixed some minor issues with the NOTIFY call. 2005-05-24 14:35:58 +00:00
Jorrit Herder
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.
 2005-05-24 10:06:17 +00:00

e5a694b126 Added note to indicate how touchy MAX_BLOCK_SIZE is at the moment. 2005-05-20 12:30:37 +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.
