1158 6656 d 6 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 6669 d 4 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 6673 d 9 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 6674 d 4 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.		  
1103 6674 d 8 h jermar /kernel/trunk/generic/src/ Remove extra before_thread_runs() calls.  
1086 6677 d 22 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.		  
1083 6678 d 22 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.  
1078 6679 d 3 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6679 d 19 h jermar /kernel/trunk/ Support for user space threads.  
1062 6679 d 22 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.		  
1060 6680 d 0 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.		  
1048 6680 d 6 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1040 6680 d 9 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.		  
1026 6680 d 21 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6680 d 22 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1007 6681 d 9 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1005 6681 d 9 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6681 d 21 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
973 6682 d 9 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6682 d 11 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6683 d 1 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
935 6684 d 3 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
907 6693 d 9 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6693 d 21 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 6696 d 7 h jermar /kernel/trunk/ Minor changes.  
897 6696 d 21 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.

ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
842 6708 d 7 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
827 6714 d 21 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
823 6715 d 21 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
