756 6722 d 12 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 6723 d 12 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 6723 d 13 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.		  
753 6723 d 20 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
752 6723 d 20 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
751 6723 d 22 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
750 6724 d 16 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.		  
749 6725 d 19 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6726 d 20 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6727 d 13 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.		  
746 6727 d 22 h jermar /kernel/trunk/ Page hash table modifications.  
745 6728 d 15 h jermar /kernel/trunk/test/mm/ Fix and cleanup frame allocator tests.
falloc1:
- fix so that it compiles on ia64
- check that frames is not NULL
falloc2:
- threads cannot be passed argument in the way this test did
(otherwise some threads will use the same value for val)
- check that frames is not NULL
- free frames at the end of the test		  
744 6728 d 16 h jermar /kernel/trunk/arch/ia64/ Remove ia64 boot as it is not needed by the simulator.  
743 6729 d 15 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.		  
742 6729 d 15 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6729 d 16 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6729 d 22 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6731 d 19 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
735 6731 d 19 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6731 d 21 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
730 6732 d 19 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6732 d 19 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
728 6734 d 13 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
727 6734 d 14 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6734 d 14 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
724 6736 d 15 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
723 6736 d 16 h palkovsky /kernel/branches/falloc_bad/generic/src/mm/ Cannot printf in frame_alloc, because on ia32/amd64 it
would print before ega_init and that stucks fs.		  
722 6736 d 17 h palkovsky /kernel/branches/falloc_bad/generic/src/main/ Fixed bad stack settings in main for main_bsp_separated_stack.  
721 6736 d 22 h bondari /kernel/branches/falloc_bad/ Failing frame allocator changes.  
720 6736 d 22 h bondari /kernel/branches/falloc_bad/ Failing frame_alloc branch - revision 719

map init directly from the physical frames it is loaded in		  
717 6738 d 18 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
