772 6770 d 3 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.  
771 6770 d 5 h palkovsky /kernel/trunk/generic/ Implemented malloc/free as SLABs.  
770 6770 d 12 h palkovsky /kernel/trunk/generic/include/ Fix context_save, so that it works even with inlines disabled (-O0).  
767 6771 d 6 h palkovsky /kernel/trunk/ Partially working SLAB CPU cache.  
766 6771 d 7 h palkovsky /kernel/trunk/ Basic SLAB (without CPU-cache) passes test.  
764 6771 d 12 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
763 6771 d 13 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
762 6771 d 14 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference		  
759 6772 d 3 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
756 6773 d 4 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 6774 d 4 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 6774 d 5 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 6774 d 13 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
747 6778 d 6 h jermar /kernel/trunk/ 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.		  
735 6782 d 12 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
730 6783 d 11 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6783 d 11 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
727 6785 d 6 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6787 d 8 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6789 d 7 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 6789 d 10 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
712 6789 d 12 h decky /kernel/trunk/ "Hello world" from user space :)  
703 6791 d 15 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().		  
699 6794 d 15 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6796 d 12 h bondari /kernel/trunk/ Frame alloc test #1  
687 6796 d 12 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6796 d 13 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6796 d 13 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 6796 d 14 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6796 d 16 h jermar /kernel/trunk/ Minor changes.  
678 6800 d 7 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
676 6800 d 10 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
673 6801 d 6 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
669 6805 d 6 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
664 6810 d 3 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6812 d 6 h decky /kernel/trunk/ initial syscall table support  
651 6816 d 4 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)		  
650 6816 d 6 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.		  
631 6820 d 7 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6820 d 9 h decky /kernel/trunk/ init task loading (yet buggy)
