Rev	Age	Author	Path	Log message
1460	6570 d 15 h	jermar	/kernel/trunk/generic/	Reference counting for futexes.
1458	6571 d 6 h	palkovsky	/kernel/trunk/	Added console support to gxemul. Wider information in thread list.
1424	6574 d 10 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	6578 d 5 h	jermar	/kernel/trunk/generic/	Some shared memory stuff (not completed). Support for address space area backends. Add ELF and anonymous memory backends.
1380	6581 d 8 h	jermar	/kernel/trunk/	Turn address space lock, address space area lock and page_ht_lock into mutexes.
1358	6585 d 11 h	jermar	/kernel/trunk/generic/	Cleanup after removal of as_area_accept and as_area_send.
1288	6596 d 16 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.
1264	6600 d 16 h	jermar	/kernel/trunk/generic/	Improve Doxygen-comments.
1248	6604 d 11 h	jermar	/kernel/trunk/	Add some @file doxygen comments and improve already existing comments.
1239	6605 d 10 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	6605 d 16 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1229	6607 d 15 h	jermar	/kernel/trunk/	Remove the outdated TODO file. Improve doxygen comments here and there.
1227	6608 d 12 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.
1221	6609 d 5 h	decky	/kernel/trunk/	printf-related and other code cleanup
1210	6610 d 15 h	vana	/kernel/trunk/	Incomplete VHPT walker support for Itanium
1196	6615 d 15 h	cejka	/kernel/trunk/	Printf ported back from uspace to kernel. Printf calls changed to match new conventions.
1187	6618 d 10 h	jermar	/kernel/trunk/	Cleanup pm.c and pm.h code on ia32 and amd64. Add before_task_runs() and before_task_runs_arch() for each architecture. Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
1185	6618 d 13 h	jermar	/kernel/trunk/	Add task_create_arch() for all architectures.
1184	6618 d 13 h	jermar	/kernel/trunk/	Move arch/thread.h to arch/proc/thread.h on all architectures. Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures. Similarily, add task_arch_t arch on all architectures. On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port permission bitmap. For the same reason, define per task IO port permission bitmaps on ia32 and amd64.
1178	6619 d 11 h	jermar	/kernel/trunk/	Add task_find_by_id(). Add kernel support for SYS_MAP_PHYSMEM.
1177	6619 d 15 h	jermar	/kernel/trunk/generic/	Modify B+tree node key width to be 64-bit wide on all platforms.
1176	6619 d 16 h	jermar	/kernel/trunk/generic/	Kernel support for SYS_GET_TASK_ID syscall.
1174	6619 d 17 h	jermar	/kernel/trunk/	Start capabilities support.
1171	6619 d 19 h	jermar	/kernel/trunk/	Initialize ARCH_THREAD_DATA on all architectures. On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
1170	6620 d 11 h	vana	/kernel/trunk/	Stack size definition macro definition fix
1168	6622 d 9 h	vana	/kernel/trunk/	Thread RSE support completion (kernel)
1159	6622 d 12 h	jermar	/kernel/trunk/generic/	Replace list of all tasks with B+tree of all tasks.
1158	6622 d 13 h	jermar	/kernel/trunk/generic/	Replace list of all threads with B+tree of all threads. Add function thread_exists() for querying existence of thread.
1138	6635 d 11 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().
1115	6639 d 16 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.
1104	6640 d 11 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.
1103	6640 d 15 h	jermar	/kernel/trunk/generic/src/	Remove extra before_thread_runs() calls.
1086	6644 d 5 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.
1083	6645 d 5 h	palkovsky	/kernel/trunk/generic/src/	Fixed incorrect locking in ipc.
1078	6645 d 10 h	jermar	/kernel/trunk/	Improved uspace threads. ia64 needs fixing.
1066	6646 d 2 h	jermar	/kernel/trunk/	Support for user space threads.
1062	6646 d 5 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	6646 d 7 h	palkovsky	/kernel/trunk/	Added task_print. Fixed ipc to support connect_me_to.
1048	6646 d 13 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	6646 d 16 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.
