1108 6669 d 0 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6669 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.		  
1093 6672 d 1 h palkovsky /kernel/trunk/generic/src/mm/ Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced).		  
1076 6674 d 10 h jermar /kernel/trunk/generic/src/mm/ Unlock address space area when returning error.  
1070 6674 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6674 d 23 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1048 6675 d 8 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 6675 d 10 h jermar /kernel/trunk/ Page table locking.  
1037 6675 d 11 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1026 6675 d 23 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1008 6676 d 10 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.		  
1002 6676 d 22 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
983 6677 d 7 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6677 d 8 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6677 d 9 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6677 d 11 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
946 6679 d 1 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
852 6701 d 8 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
840 6704 d 9 h jermar /kernel/trunk/ Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.  
826 6710 d 1 h jermar /kernel/trunk/ Add page_mapping_remove().  
824 6710 d 13 h palkovsky /kernel/trunk/ Use less frames for zone configuration data after merge.  
823 6710 d 23 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6711 d 0 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 6711 d 0 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.		  
815 6711 d 10 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6711 d 10 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
813 6711 d 23 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.		  
793 6713 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.		  
792 6713 d 9 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
791 6713 d 21 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
789 6714 d 1 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 6714 d 5 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6714 d 6 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6714 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		  
785 6714 d 8 h jermar /kernel/trunk/generic/src/ Comments clarification.  
783 6714 d 9 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 6714 d 10 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6714 d 22 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6715 d 1 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
778 6715 d 4 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
