800 6663 d 15 h palkovsky /kernel/trunk/arch/amd64/include/ Split AMD interrupt.h from ia32 version.  
799 6663 d 15 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6663 d 15 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
797 6663 d 18 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6663 d 19 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.		  
794 6663 d 20 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6663 d 21 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
792 6663 d 22 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
791 6664 d 10 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
790 6664 d 14 h jermar /kernel/trunk/ Generic chaining hash table.  
789 6664 d 14 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 6664 d 18 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6664 d 19 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6664 d 20 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 6664 d 22 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6664 d 22 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6664 d 22 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 6665 d 0 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6665 d 11 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6665 d 15 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
779 6665 d 15 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 6665 d 17 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
777 6665 d 18 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6665 d 21 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6665 d 22 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 6666 d 10 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 6666 d 11 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6666 d 13 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
770 6666 d 20 h palkovsky /kernel/trunk/generic/include/ Fix context_save, so that it works even with inlines disabled (-O0).  
769 6667 d 10 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 6667 d 12 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6667 d 14 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6667 d 14 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6667 d 15 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6667 d 20 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6667 d 21 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6667 d 22 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
761 6667 d 23 h jermar /kernel/trunk/doc/ Remove document describing more relaxed preemption model than the one used in the current kernel.  
760 6667 d 23 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
759 6668 d 10 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.
