1468 6558 d 9 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 6558 d 13 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1424 6562 d 8 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.		  
1409 6566 d 3 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1358 6573 d 9 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6584 d 14 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.		  
1248 6592 d 8 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6593 d 8 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.		  
1235 6593 d 14 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1229 6595 d 13 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 6596 d 10 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.		  
1196 6603 d 12 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1185 6606 d 11 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1178 6607 d 9 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1177 6607 d 13 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1176 6607 d 14 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1174 6607 d 15 h jermar /kernel/trunk/ Start capabilities support.  
1170 6608 d 9 h vana /kernel/trunk/ Stack size definition macro definition fix  
1168 6610 d 7 h vana /kernel/trunk/ Thread RSE support completion (kernel)  
1159 6610 d 10 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1115 6627 d 14 h jermar /kernel/trunk/generic/src/proc/ Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.		  
1086 6632 d 3 h palkovsky /kernel/trunk/generic/ Untested better IPC functions.
* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.		  
1078 6633 d 8 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6634 d 0 h jermar /kernel/trunk/ Support for user space threads.  
1062 6634 d 3 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
1060 6634 d 5 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.		  
1048 6634 d 11 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.		  
1040 6634 d 13 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.		  
1026 6635 d 2 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6635 d 2 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1005 6635 d 14 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6636 d 2 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
973 6636 d 14 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6636 d 16 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6637 d 6 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
822 6670 d 3 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
814 6670 d 13 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
788 6673 d 8 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
703 6696 d 13 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
624 6725 d 10 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.
