826 6678 d 6 h jermar /kernel/trunk/ Add page_mapping_remove().  
824 6678 d 18 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
823 6679 d 4 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6679 d 5 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
820 6679 d 6 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
 
817 6679 d 14 h palkovsky /kernel/trunk/ Small cleanup.  
816 6679 d 14 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
 
815 6679 d 15 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
814 6679 d 15 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
813 6680 d 4 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.
 
799 6681 d 7 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
794 6681 d 12 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6681 d 13 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 6681 d 14 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
791 6682 d 2 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab
 
790 6682 d 6 h jermar /kernel/trunk/ Generic chaining hash table.  
789 6682 d 6 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 6682 d 10 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6682 d 11 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
786 6682 d 12 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 6682 d 13 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6682 d 14 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6682 d 14 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 6682 d 16 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6683 d 3 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.
 
780 6683 d 6 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
779 6683 d 7 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 6683 d 9 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
777 6683 d 10 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6683 d 13 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.
 
775 6683 d 14 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 6684 d 2 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 6684 d 3 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6684 d 5 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
770 6684 d 12 h palkovsky /kernel/trunk/generic/include/ Fix context_save, so that it works even with inlines disabled (-O0).  
769 6685 d 2 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 6685 d 4 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6685 d 5 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6685 d 6 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6685 d 7 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
