Rev	Age	Author	Path	Log message
2067	6351 d 14 h	jermar	/trunk/kernel/	More formatting changes.
2040	6375 d 15 h	decky	/trunk/kernel/generic/src/proc/	add forgotten btree_remove()
2030	6376 d 17 h	decky	/trunk/kernel/	thread CPU cycles accounting
1888	6466 d 12 h	jermar	/trunk/	C99 compliant header guards (hopefully) everywhere in the kernel. Formatting and indentation changes. Small improvements in sparc64.
1882	6467 d 16 h	jermar	/trunk/kernel/	Support for sparc64 FPU context.
1854	6482 d 18 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.
1787	6531 d 11 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1780	6538 d 12 h	jermar	/kernel/trunk/	Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
1757	6552 d 17 h	jermar	/kernel/trunk/	Cleanup of comments.
1708	6556 d 18 h	jermar	/kernel/trunk/	Fix some broken doxygen comments.
1705	6558 d 17 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	6559 d 14 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
1576	6568 d 9 h	jermar	/kernel/trunk/	Make use of thread_join_timeout() and thread_detach() in kernel. Improved comments in slab.h.
1571	6568 d 12 h	jermar	/kernel/trunk/generic/	thread_join_timeout() and thread_detach() implementation. Needs more thorough testing.
1380	6583 d 9 h	jermar	/kernel/trunk/	Turn address space lock, address space area lock and page_ht_lock into mutexes.
1264	6602 d 17 h	jermar	/kernel/trunk/generic/	Improve Doxygen-comments.
1248	6606 d 12 h	jermar	/kernel/trunk/	Add some @file doxygen comments and improve already existing comments.
1229	6609 d 16 h	jermar	/kernel/trunk/	Remove the outdated TODO file. Improve doxygen comments here and there.
1221	6611 d 6 h	decky	/kernel/trunk/	printf-related and other code cleanup
1196	6617 d 16 h	cejka	/kernel/trunk/	Printf ported back from uspace to kernel. Printf calls changed to match new conventions.
1187	6620 d 11 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.
1115	6641 d 17 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	6642 d 12 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.
1086	6646 d 6 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.
1062	6648 d 6 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.
1007	6649 d 17 h	decky	/kernel/trunk/	ppc32: preemptive scheduling works now FPU context saving disabled for now
907	6661 d 17 h	palkovsky	/kernel/trunk/generic/src/proc/	Correct sleeping on memory allocation during FPU lazy switch.
906	6662 d 5 h	palkovsky	/kernel/trunk/	Added lazy fpu context allocation. - threads that don't use fpu, don't get allocated fpu context - fpu context alignment on AMD64 nicely disappeared
898	6664 d 15 h	jermar	/kernel/trunk/	Minor changes.
897	6665 d 5 h	jermar	/kernel/trunk/	sparc64 work. Fix KBD_VIRT_ADDRESS. Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial. Add after_thread_ran() to the scheduler. Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack. Add dummy after_thread_ran_arch() to all other architectures. Add dtlb_insert_mapping() to promote code reuse.
827	6683 d 5 h	palkovsky	/kernel/trunk/	Unimportant changes regarding FPU context.
823	6684 d 5 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
814	6684 d 16 h	palkovsky	/kernel/trunk/	Cleanup o frame allocator. Removed early_malloc & initial heap. Will break ia64, ppc & sparc. Added e820 table print.
788	6687 d 11 h	jermar	/kernel/trunk/	Move list and fifo data types to adt/.
787	6687 d 12 h	palkovsky	/kernel/trunk/generic/	Added constructor/destructor calls to SLAB. Changed allocation of thread_t structure to use SLAB.
785	6687 d 14 h	jermar	/kernel/trunk/generic/src/	Comments clarification.
784	6687 d 15 h	palkovsky	/kernel/trunk/generic/src/proc/	Cleanup of scheduler code
783	6687 d 15 h	palkovsky	/kernel/trunk/generic/	Fixed some typos in slab allocator. Scheduler now has better algorithm on load balancing. Unfortunately it reveals deadlock in slab allocator :-/
779	6688 d 8 h	jermar	/kernel/trunk/generic/	Simplify load balancing activation. This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems.
775	6688 d 15 h	palkovsky	/kernel/trunk/generic/	Added scheduler queues output. The scheduler is buggy - on SMP the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything is on the first cpu. The slab allocator passes tests in this configuration, but in slightly different(more efficient) locking order it panics. TODO: Find out why does it panic.
