8214e5e284 Removed racy COW optimization 
- enabling writing in COW once phys block is reference only once is racy if VM
  is preemptible. original memory location may get overwritten before COW copies
  the memory

- problem when DEBUG_RACE is on and a big problem for SMP

a mountpoint until that's properly fixed.)

ed0b81c25c Removed some unused variables and functions. 2010-06-02 19:41:38 +00:00
Thomas Veerman
6bbcab3ec4 Clean up MFS a bit: 
- Remove unused includes.
 - Add include guards to headers.
 - Use unsigned variables in case they're never going to hold a negative
   value. This causes GCC's complaints to disappear and should make flexelint
   a lot happier, too.
 - Make functions private when they're used only within a module.
 - Remove unused variables.
 - Add casts where appropriate.

a8111c5027 Various small scheduling related fixes 2010-05-26 07:16:39 +00:00
Tomas Hruby
451a6890d6 scheduling - time quantum in miliseconds 
- Currently the cpu time quantum is timer-ticks based. Thus the
  remaining quantum is decreased only if the processes is interrupted
  by a timer tick. As processes block a lot this typically does not
  happen for normal user processes. Also the quantum depends on the
  frequency of the timer.

- This change makes the quantum miliseconds based. Internally the
  miliseconds are translated into cpu cycles. Everytime userspace
  execution is interrupted by kernel the cycles just consumed by the
  current process are deducted from the remaining quantum.

- It makes the quantum system timer frequency independent.

- The boot processes quantum is loosely derived from the tick-based
  quantas and 60Hz timer and subject to future change

- the 64bit arithmetics is a little ugly, will be changes once we have
  compiler support for 64bit integers (soon)

bcdaf033b5 pm - fix sched interaction

dcc81d73e8 boot image - no need for entry point

  to 0 and RS uses a.out headers.
