Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.

/kernel/trunk/generic/src/mm/
Fix bug with refcounts in frame allocator after zone_merge. (it caused some
frames not to be coalesced).

/kernel/trunk/generic/src/mm/
Unlock address space area when returning error.
1070
6769 d 0 h
jermar
/kernel/trunk/
More checks for address space area conflicts.
1063

Add support for more then 2GB of address space for AMD64.
1048
6769 d 19 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.

Page table locking.

support for more init tasks
(might break some archs yet)
1026
6770 d 10 h
jermar
/kernel/trunk/generic/
Support only anonymous address space areas.
1008
6770 d 22 h
jermar
/kernel/trunk/
Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.

/kernel/trunk/generic/
More lightweighed TLB shootdown implementation.
983
6771 d 19 h

Small speed update of ipc.
Fixed some bugs regarding pages in mremap.

palkovsky
/kernel/trunk/generic/
Added simpler userspace starting.
946
6773 d 12 h
jermar
/kernel/trunk/generic/
Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.
852
6795 d 19 h
palkovsky
/kernel/trunk/
Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)
840
6798 d 21 h
jermar
/kernel/trunk/
Fix filling of hardcoded_ktext_size and hardcoded_kdata_size to use 64 bit stores on ia64.
826
6804 d 12 h
jermar
/kernel/trunk/
Add page_mapping_remove().
824
6805 d 1 h
palkovsky
/kernel/trunk/
Use less frames for zone configuration data after merge.
823
6805 d 10 h
jermar
/kernel/trunk/
Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
822
6805 d 11 h
palkovsky
/kernel/trunk/
Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
820
6805 d 12 h
jermar
/kernel/trunk/
Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
815
6805 d 21 h
jermar
/kernel/trunk/
Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile.
814
6805 d 21 h
palkovsky
/kernel/trunk/
Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
813
6806 d 10 h
jermar
/kernel/trunk/
Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.
793
6807 d 19 h
jermar
/kernel/trunk/
Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.
792
6807 d 20 h
jermar
/kernel/trunk/
Page hash table architectures now use generic hash table to manage
mappings.
791
6808 d 8 h
palkovsky
/kernel/trunk/generic/
better utilization of memory in slab alloc
removed malloc-8 slab
789
6808 d 12 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
6808 d 16 h
jermar
/kernel/trunk/
Move list and fifo data types to adt/.
787
6808 d 17 h

Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.

frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
785
6808 d 19 h
jermar
/kernel/trunk/generic/src/
Comments clarification.
783
6808 d 20 h

Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/
782
6808 d 22 h
palkovsky
/kernel/trunk/generic/src/mm/
Small locking performance tweak.
781
6809 d 9 h

/kernel/trunk/generic/
Still better locking - does not hold global spinlock when
destroying cache.
780
6809 d 12 h
palkovsky
/kernel/trunk/
Small fix in slab allocator for large-sized slabs.
778
6809 d 15 h

/kernel/trunk/
Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
776
6809 d 19 h
palkovsky
/kernel/trunk/generic/
Added more granular locking to slab allocator and thus fix
hopefully last race condition.
