4dfe841667 No driver in dmap is NONE instead of 0. 2005-10-10 14:27:41 +00:00
Ben Gras
86ed54ee94 FS: 
. unmap device drivers from dmap when PM signals they are dead
	. new null-io function (no_dev_io) to fill in for io functions
	  of unmapped drivers
	. driver (process number) of unmapped drivers is NONE instead of
	  0 (a valid process number)

IS:
	. print mutable flag of dmap table too

FS changes require sync() to be done 'manually' (currently by
reboot/shutdown) at shutdown time; could be caught by SIGTERM in
the future.

- make clean image: only builds new boot image (about 5 sec. now!)

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).

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.

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).
