787 6677 d 17 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6677 d 18 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		  
785 6677 d 20 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6677 d 20 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6677 d 20 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 :-/		  
782 6677 d 22 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6678 d 9 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6678 d 13 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
779 6678 d 13 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 15 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
777 6678 d 16 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6678 d 19 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6678 d 20 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 6679 d 8 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 6679 d 9 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6679 d 11 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
769 6680 d 8 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 6680 d 10 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6680 d 12 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6680 d 12 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.
