907 6681 d 1 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6681 d 12 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 6683 d 23 h jermar /kernel/trunk/ Minor changes.  
897 6684 d 13 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 6691 d 13 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
842 6695 d 23 h palkovsky /kernel/trunk/ Avoid memory exhaustion in thread_create in slab2 test.  
827 6702 d 13 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
823 6703 d 13 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
822 6703 d 14 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 6704 d 0 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
788 6706 d 19 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6706 d 20 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6706 d 20 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 6706 d 22 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6706 d 22 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6706 d 23 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 6707 d 15 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 6707 d 18 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
775 6707 d 23 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 6709 d 23 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
703 6730 d 0 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 6734 d 20 h bondari /kernel/trunk/ Frame alloc test #1  
678 6738 d 16 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
675 6738 d 23 h jermar /kernel/trunk/generic/src/ Clean up.  
662 6750 d 14 h decky /kernel/trunk/ initial syscall table support  
650 6754 d 14 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 6758 d 15 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
625 6758 d 20 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.		  
624 6758 d 21 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6759 d 2 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
557 6766 d 23 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
552 6767 d 15 h palkovsky /kernel/trunk/ Named spinlocks  
548 6767 d 17 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6769 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6769 d 17 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6769 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6781 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6789 d 17 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.		  
475 6793 d 23 h jermar /SPARTAN/trunk/ Define atomic_t type.  
458 6796 d 0 h decky /SPARTAN/trunk/ make configuration variables usage consistent
