789 6677 d 13 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
788 6677 d 17 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6677 d 18 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6677 d 19 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed		  
783 6677 d 21 h palkovsky /kernel/trunk/generic/ Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/		  
781 6678 d 10 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
779 6678 d 14 h jermar /kernel/trunk/generic/ Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems.		  
778 6678 d 16 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
777 6678 d 17 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6678 d 20 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6678 d 21 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.		  
772 6679 d 10 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6679 d 12 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
770 6679 d 19 h palkovsky /kernel/trunk/generic/include/ Fix context_save, so that it works even with inlines disabled (-O0).  
767 6680 d 13 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6680 d 14 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6680 d 19 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6680 d 20 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6680 d 21 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6681 d 9 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.
