/kernel/trunk/generic/
Added more granular locking to slab allocator and thus fix
hopefully last race condition.
775
6766 d 10 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.

/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.

/kernel/trunk/
Fixed non-initialized cpu-cache.
771
6767 d 0 h

/kernel/trunk/generic/
Implemented malloc/free as SLABs.
770
6767 d 7 h
palkovsky
/kernel/trunk/generic/include/
Fix context_save, so that it works even with inlines disabled (-O0).
769
6767 d 21 h

/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
6768 d 0 h
palkovsky
/kernel/trunk/
Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.
767
6768 d 1 h
palkovsky
/kernel/trunk/
Partially working SLAB CPU cache.
766
6768 d 2 h
palkovsky
/kernel/trunk/
Basic SLAB (without CPU-cache) passes test.
765
6768 d 2 h

Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764
6768 d 7 h
palkovsky
/kernel/trunk/
Tested basic non-cached slab allocation.
763
6768 d 8 h
jermar
/kernel/trunk/
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
762
6768 d 9 h
palkovsky
/kernel/trunk/
Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
759
6768 d 22 h
palkovsky
/kernel/trunk/
Skeleton of SLAB allocator.
757
6769 d 3 h
jermar
/kernel/trunk/
Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.
756
6769 d 23 h

/kernel/trunk/
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
755
6770 d 23 h
jermar
/kernel/trunk/
Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.
754
6771 d 0 h
jermar
/kernel/trunk/generic/
Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.
752
6771 d 8 h
jermar
/kernel/trunk/generic/include/
Replace % operator by explicit overflow test to make this ADT compile on ia64.
