1086 6650 d 21 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 6651 d 21 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.  
1078 6652 d 2 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1066 6652 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1062 6652 d 21 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 6652 d 23 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.
 
1048 6653 d 5 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 6653 d 7 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 6653 d 20 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6653 d 20 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1007 6654 d 8 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now
 
1005 6654 d 8 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6654 d 20 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
973 6655 d 8 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6655 d 10 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.
 
955 6656 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
935 6657 d 2 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
907 6666 d 8 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6666 d 20 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 6669 d 6 h jermar /kernel/trunk/ Minor changes.  
897 6669 d 20 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.
 
860 6676 d 20 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
842 6681 d 6 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
827 6687 d 20 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
823 6688 d 20 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
822 6688 d 21 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
814 6689 d 7 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
788 6692 d 2 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6692 d 3 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
786 6692 d 4 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
 
785 6692 d 5 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6692 d 6 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6692 d 6 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 6692 d 23 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.
 
777 6693 d 2 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
775 6693 d 6 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.
 
762 6695 d 6 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
703 6715 d 7 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
689 6720 d 3 h bondari /kernel/trunk/ Frame alloc test #1  
678 6723 d 23 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir
