792 6667 d 10 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
791 6667 d 22 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab
 
790 6668 d 2 h jermar /kernel/trunk/ Generic chaining hash table.  
789 6668 d 2 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 6668 d 6 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6668 d 7 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
786 6668 d 8 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 6668 d 9 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6668 d 10 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6668 d 10 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 6668 d 11 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6668 d 23 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.
 
780 6669 d 2 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
779 6669 d 3 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 6669 d 5 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
777 6669 d 6 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6669 d 9 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.
 
775 6669 d 10 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 6669 d 22 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 6669 d 23 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.
