775 6758 d 8 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 6758 d 20 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 6758 d 21 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6758 d 22 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
769 6759 d 19 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 6759 d 22 h palkovsky /kernel/trunk/ Debugged slab allocator. It currently supports per-CPU cache on 1 cpu.  
767 6759 d 23 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6760 d 0 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
765 6760 d 0 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6760 d 5 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6760 d 6 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6760 d 7 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6760 d 20 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6761 d 1 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 6761 d 21 h jermar /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 6762 d 21 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 6762 d 22 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.		  
740 6769 d 7 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
735 6771 d 5 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
727 6773 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6776 d 1 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6778 d 0 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		  
711 6778 d 5 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
704 6780 d 5 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6780 d 8 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().		  
701 6782 d 23 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.		  
699 6783 d 8 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6785 d 5 h bondari /kernel/trunk/ Frame alloc test #1  
687 6785 d 5 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6785 d 6 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6785 d 6 h jermar /kernel/trunk/ 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.		  
683 6785 d 7 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
677 6789 d 3 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6789 d 3 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
654 6804 d 4 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.		  
629 6809 d 2 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6809 d 5 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 6809 d 6 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6809 d 11 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.		  
615 6811 d 10 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.
