Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.

Partially working SLAB CPU cache.
766
6713 d 15 h
palkovsky
/kernel/trunk/
Basic SLAB (without CPU-cache) passes test.

Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764

Tested basic non-cached slab allocation.

Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.

Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
759

Skeleton of SLAB allocator.

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.

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

/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
6716 d 13 h

/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

/kernel/trunk/generic/include/
Replace % operator by explicit overflow test to make this ADT compile on ia64.
747

ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).
Add missing header to sparc64.
Remove excessive header from debug.h.

Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
729
6725 d 19 h
jermar
/kernel/trunk/generic/include/
In-array FIFO implementation.
727
6727 d 15 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.

Commit of the falloc_bad branch to trunk (719:723).
718
6731 d 16 h
decky
/kernel/trunk/
interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in
717

remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
714

syscall handler return value
uspace task termination (primitive)

Make various mips32 tlb manipulation functions preserve EntryHi register.
Cleanup and more precise comments for previous commit.

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().
701
6736 d 14 h
jermar
/kernel/trunk/generic/src/mm/
Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.

Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.

Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
