1780 6513 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6521 d 8 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6524 d 2 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1757 6527 d 5 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6534 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1682 6537 d 10 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1677 6538 d 3 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1554 6543 d 20 h jermar /kernel/trunk/generic/src/mm/ Improve comment in slab.c.  
1428 6550 d 19 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.		  
1288 6573 d 6 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1248 6581 d 0 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1224 6585 d 3 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1196 6592 d 4 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1144 6606 d 23 h jermar /kernel/trunk/ Completed B+-tree support.
Enable btree_remove().
Reorder some static functions and group them together.
Fix order of nodes in the leaf_head list.		  
822 6658 d 19 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 6659 d 5 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
791 6661 d 16 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
789 6661 d 20 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
788 6662 d 0 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6662 d 1 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6662 d 2 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 6662 d 3 h jermar /kernel/trunk/generic/src/ Comments clarification.  
783 6662 d 4 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 :-/		  
782 6662 d 5 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6662 d 16 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6662 d 20 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
778 6662 d 23 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
776 6663 d 3 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6663 d 4 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.		  
773 6663 d 16 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.		  
772 6663 d 17 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6663 d 18 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
769 6664 d 15 h palkovsky /kernel/trunk/ SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.		  
768 6664 d 18 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6664 d 19 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6664 d 20 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6664 d 20 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6665 d 1 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6665 d 3 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6665 d 4 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
