1007 6621 d 18 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now
 
907 6633 d 19 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6634 d 6 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 6636 d 17 h jermar /kernel/trunk/ Minor changes.  
897 6637 d 7 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 6655 d 7 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
823 6656 d 7 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
814 6656 d 18 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
788 6659 d 13 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6659 d 14 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
785 6659 d 16 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6659 d 16 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6659 d 17 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 6660 d 10 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 6660 d 17 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.
 
703 6682 d 18 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().
 
675 6691 d 17 h jermar /kernel/trunk/generic/src/ Clean up.  
650 6707 d 8 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.
 
631 6711 d 9 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
625 6711 d 14 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
