2048 6451 d 7 h jermar /trunk/ Formatting and indentation changes.  
2042 6453 d 10 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again		  
2041 6453 d 11 h decky /trunk/kernel/generic/src/proc/ revert 2040  
2040 6453 d 13 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 6453 d 14 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2035 6454 d 11 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2032 6454 d 12 h decky /trunk/kernel/generic/src/proc/ proper initialization of last_cycle  
2030 6454 d 14 h decky /trunk/kernel/ thread CPU cycles accounting  
2000 6469 d 15 h decky /trunk/kernel/ move files to more proper locations  
1888 6544 d 9 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6545 d 13 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1880 6548 d 5 h jermar /trunk/ Small improvements here and there.  
1864 6555 d 3 h jermar /trunk/ sparc64 update.
- Prototype userspace layer implementation that
at least relates to sparc64 and compiles cleanly.
- Fixes for kernel's preemptible_handler and code
related to running userspace.
- Enable userspace. Several dozen instructions
are now run in userspace! We are pretty near
the userspace milestone for sparc64.		  
1854 6560 d 15 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1839 6584 d 10 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6592 d 3 h decky /trunk/kernel/generic/ initial security context support  
1787 6609 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6616 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6624 d 16 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6627 d 10 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1757 6630 d 14 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6632 d 15 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6634 d 15 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6636 d 15 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6637 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6640 d 13 h jermar /kernel/trunk/generic/src/proc/ Fix double thread_join() in ktaskgc.
In thread_create(), lock TASK with interrupts disabled again.
thread_join_timeout() can use ordinary waitq_sleep_timeout().		  
1684 6640 d 16 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1680 6641 d 2 h jermar /kernel/trunk/generic/src/proc/ Add interrupts_restore() to thread_join_timeout(). Note that this is not necessary, because
waitq_sleep_finish() does the job for thread_join_timeout(). However, the code looks more
correct in the form with interrupts_restore().		  
1676 6641 d 13 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 6642 d 17 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1636 6644 d 2 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1600 6644 d 17 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 6644 d 18 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6644 d 19 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1589 6645 d 8 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6645 d 8 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().		  
1587 6645 d 9 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 6645 d 12 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6645 d 15 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1581 6645 d 18 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.
