2839	5928 d 4 h	svoboda	/branches/tracing/kernel/generic/	Add thread_attach_by_id() and use it to do ipc_connect_kbox() with proper locking
2826	5932 d 12 h	svoboda	/branches/tracing/kernel/generic/	Move debug_go_call from task struct to thread struct
2825	5932 d 12 h	svoboda	/branches/tracing/kernel/generic/	Introduce task debug-states (udebug_task_state_t)
2808	5934 d 2 h	svoboda	/branches/tracing/	add kernel answerbox+thread to mediate access to task's memory
2804	5935 d 8 h	svoboda	/branches/tracing/kernel/generic/	allow for attaching to tasks with sleeping threads
2801	5935 d 13 h	svoboda	/branches/tracing/	[tracing] initial debug interface support
2799	5935 d 14 h	svoboda	/branches/tracing/	Revert all changes in tracing branch (sync to r2785 of trunk)
2787	5944 d 6 h	decky	/branches/tracing/	add dynamic linking, debugging and tracing branch
2504	6186 d 3 h	jermar	/trunk/kernel/generic/	Give the AVL tree walkers the possibility to take an argument. Each walker is now supposed to return a bool value to support walk termination. Switch over from the tasks_btree B+tree to tasks_tree AVL tree. This makes the fix for ticket #48 complete.
2446	6244 d 6 h	jermar	/trunk/kernel/generic/	More efficient and simpler task termination. Based on the assumption, that after its creation, only the task itself can create more threads for itself, the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference counting. As for userspace threads, even though there could be a global garbage collector for joining threads, it is much simpler if the uinit thread detaches itself before switching to userspace. task_kill() is now an idempotent operation. It just instructs the threads within a task to exit. Change in the name of a thread state: Undead -> JoinMe.
2227	6297 d 16 h	decky	/trunk/kernel/	start shutdown infrastructure
2216	6299 d 2 h	decky	/trunk/	make thread ID 64 bit (task ID is 64 bit already) cleanup thread syscalls
2106	6362 d 9 h	jermar	/trunk/kernel/	Merge as_t structure into one and leave the differring parts in as_genarch_t. Indentation and formatting changes in header files.
2105	6366 d 9 h	decky	/trunk/kernel/	move ipc structures to ipc.h
2103	6367 d 2 h	decky	/trunk/kernel/generic/include/	move timeout_t to timeout.h move other helper types to thread.h
2096	6367 d 4 h	decky	/trunk/kernel/generic/include/	move thread_t to thread.h
2093	6367 d 5 h	decky	/trunk/kernel/	spinlock extern declaration macro
2092	6367 d 6 h	decky	/trunk/kernel/generic/include/	move cpu_t to cpu.h
2090	6368 d 5 h	decky	/trunk/kernel/generic/include/proc/	cleanup garbage
2089	6368 d 9 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6379 d 2 h	jermar	/trunk/	(c) versus (C)
2039	6413 d 10 h	decky	/trunk/kernel/generic/	accumulate task accounting, run tests as separate kernel task
1888	6504 d 5 h	jermar	/trunk/	C99 compliant header guards (hopefully) everywhere in the kernel. Formatting and indentation changes. Small improvements in sparc64.
1820	6551 d 23 h	decky	/trunk/kernel/generic/	initial security context support
1787	6569 d 4 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6576 d 5 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1702	6597 d 8 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1587	6605 d 5 h	jermar	/kernel/trunk/	task_destroy() implementation, fixes in as_destroy() and task_kill(). This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
1585	6605 d 8 h	jermar	/kernel/trunk/generic/	Kill task when its main thread exits.
1583	6605 d 11 h	jermar	/kernel/trunk/generic/	Make ktaskclnp call ipc_cleanup and futex_cleanup.
1579	6606 d 0 h	jermar	/kernel/trunk/generic/	Framework for task_kill(). Some pieces (e.g. implementation of ktask_cleanup() kernel thread and task_destroy() function) are missing. Changed locking order for task lock, threads_lock and thread lock from threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
1568	6606 d 6 h	palkovsky	/kernel/trunk/generic/	Slightly remodelled ipc hangups to facilitate correct cleanup. Doc updates for frame allocator.
1468	6610 d 6 h	jermar	/kernel/trunk/	Function for destroying address space for which there is no other reference in the kernel.
1460	6610 d 10 h	jermar	/kernel/trunk/generic/	Reference counting for futexes.
1358	6625 d 5 h	jermar	/kernel/trunk/generic/	Cleanup after removal of as_area_accept and as_area_send.
1235	6645 d 11 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.
1227	6648 d 6 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.
1187	6658 d 5 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	6658 d 7 h	jermar	/kernel/trunk/	Add task_create_arch() for all architectures.
1184	6658 d 8 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.
