1187	6786 d 16 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	6807 d 21 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	6808 d 16 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	6812 d 10 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	6814 d 11 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	6815 d 21 h	decky	/kernel/trunk/	ppc32: preemptive scheduling works now FPU context saving disabled for now
907	6827 d 21 h	palkovsky	/kernel/trunk/generic/src/proc/	Correct sleeping on memory allocation during FPU lazy switch.
906	6828 d 9 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	6830 d 20 h	jermar	/kernel/trunk/	Minor changes.
897	6831 d 9 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	6849 d 10 h	palkovsky	/kernel/trunk/	Unimportant changes regarding FPU context.
823	6850 d 10 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
814	6850 d 21 h	palkovsky	/kernel/trunk/	Cleanup o frame allocator. Removed early_malloc & initial heap. Will break ia64, ppc & sparc. Added e820 table print.
788	6853 d 15 h	jermar	/kernel/trunk/	Move list and fifo data types to adt/.
787	6853 d 16 h	palkovsky	/kernel/trunk/generic/	Added constructor/destructor calls to SLAB. Changed allocation of thread_t structure to use SLAB.
785	6853 d 19 h	jermar	/kernel/trunk/generic/src/	Comments clarification.
784	6853 d 19 h	palkovsky	/kernel/trunk/generic/src/proc/	Cleanup of scheduler code
783	6853 d 19 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	6854 d 12 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	6854 d 19 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.
