782 6666 d 7 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6666 d 18 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6666 d 22 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
778 6667 d 0 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
776 6667 d 5 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6667 d 6 h palkovsky /kernel/trunk/generic/ Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.		  
773 6667 d 18 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.		  
772 6667 d 19 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6667 d 20 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
769 6668 d 17 h palkovsky /kernel/trunk/ SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.		  
768 6668 d 20 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6668 d 21 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6668 d 22 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6668 d 22 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6669 d 3 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6669 d 4 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6669 d 6 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6669 d 18 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.
