1968 6426 d 3 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.
 
1963 6426 d 3 h jermar /tags/0.1.1/ Tagging release 0.1.1  
1329 6592 d 7 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1306 6595 d 9 h jermar /kernel/trunk/generic/ Add SYS_AS_AREA_DESTROY syscall.
Add few error codes to errno.h
and change as.c accordingly.
 
1288 6601 d 13 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1239 6610 d 7 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.
 
1238 6610 d 8 h jermar /kernel/trunk/generic/ Rename SYS_AS_AREA_SHARE_APPROVE and SYS_AS_AREA_SHARE_PERFORM, resp., to
SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND, resp. in syscall_t.

Fix prototype of as_area_send() to take only base address of the address
space area as a parameter and read size and flags from the address space
area found at this base address.
 
1236 6610 d 13 h jermar /kernel/trunk/generic/ Add frame_reference_add().  
1235 6610 d 13 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.
 
1229 6612 d 12 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1227 6613 d 9 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
 
1178 6624 d 8 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.
 
1149 6633 d 2 h jermar /kernel/trunk/generic/include/mm/ s/B+-tree/B+tree/  
1147 6633 d 2 h jermar /kernel/trunk/generic/ Deploy B+tree in address space area management.
Change as_remap() to check for conflicts with other address space areas only when the area in question grows.
 
1139 6637 d 6 h jermar /kernel/trunk/generic/include/ Fix comments.  
1138 6640 d 8 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 6645 d 7 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 6650 d 15 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1063 6651 d 1 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1048 6651 d 10 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 6651 d 12 h jermar /kernel/trunk/ Page table locking.  
1026 6652 d 1 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1002 6653 d 0 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
977 6653 d 11 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6653 d 13 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6653 d 15 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.
 
955 6654 d 5 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
946 6655 d 2 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.
 
940 6655 d 6 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
935 6655 d 7 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
880 6669 d 14 h jermar /kernel/trunk/generic/include/mm/ Fix conflict between asid_get() macro and function definitions.  
878 6670 d 11 h vana /kernel/trunk/ Active keyboard read for ia32  
869 6673 d 1 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
827 6686 d 1 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6686 d 3 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 6687 d 1 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6687 d 2 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 6687 d 2 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 6687 d 11 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
 
814 6687 d 12 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
