2071 6324 d 11 h jermar /trunk/ (c) versus (C)  
2067 6334 d 16 h jermar /trunk/kernel/ More formatting changes.  
2050 6353 d 21 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2042 6358 d 14 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again		  
2039 6358 d 19 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2032 6359 d 17 h decky /trunk/kernel/generic/src/proc/ proper initialization of last_cycle  
2030 6359 d 19 h decky /trunk/kernel/ thread CPU cycles accounting  
1854 6465 d 20 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 6489 d 15 h decky /trunk/kernel/generic/ finish security context isolation  
1820 6497 d 8 h decky /trunk/kernel/generic/ initial security context support  
1787 6514 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6521 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6529 d 21 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6532 d 15 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 6535 d 19 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6537 d 20 h decky /kernel/trunk/ make kernel prints case consistent  
1702 6542 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 6545 d 17 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().		  
1680 6546 d 7 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().		  
1661 6547 d 22 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1636 6549 d 7 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1595 6549 d 23 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 6550 d 12 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1585 6550 d 17 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1581 6550 d 23 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.		  
1579 6551 d 9 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.		  
1571 6551 d 14 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.		  
1502 6553 d 19 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1458 6556 d 9 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1288 6581 d 19 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 6589 d 14 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1210 6595 d 18 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1196 6600 d 18 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1184 6603 d 17 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.		  
1177 6604 d 19 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1171 6604 d 22 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1158 6607 d 16 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 6620 d 14 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 6624 d 19 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 6625 d 14 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.
