1139 6625 d 5 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6628 d 7 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1104 6633 d 6 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1070 6638 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6639 d 0 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1048 6639 d 9 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1044 6639 d 11 h jermar /kernel/trunk/ Page table locking.  
1026 6640 d 0 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1002 6640 d 23 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
977 6641 d 9 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6641 d 11 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6641 d 14 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6642 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
946 6643 d 1 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
940 6643 d 5 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
935 6643 d 6 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
880 6657 d 13 h jermar /kernel/trunk/generic/include/mm/ Fix conflict between asid_get() macro and function definitions.  
878 6658 d 9 h vana /kernel/trunk/ Active keyboard read for ia32  
869 6661 d 0 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
827 6674 d 0 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6674 d 2 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 6675 d 0 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6675 d 1 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 6675 d 1 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.		  
816 6675 d 9 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.		  
814 6675 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
793 6677 d 8 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.		  
791 6677 d 22 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
789 6678 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 6678 d 5 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6678 d 7 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6678 d 7 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		  
781 6678 d 22 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
778 6679 d 4 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
776 6679 d 8 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
771 6680 d 0 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
767 6681 d 1 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6681 d 2 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6681 d 7 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6681 d 8 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
