755 6692 d 5 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 6692 d 6 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 6692 d 13 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
752 6692 d 14 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
751 6692 d 16 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
750 6693 d 10 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 6694 d 13 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6695 d 14 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6696 d 7 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 6696 d 16 h jermar /kernel/trunk/ Page hash table modifications.  
745 6697 d 9 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 6697 d 9 h jermar /kernel/trunk/arch/ia64/ Remove ia64 boot as it is not needed by the simulator.  
743 6698 d 9 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.		  
742 6698 d 9 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6698 d 10 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 6698 d 15 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6700 d 12 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
735 6700 d 13 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
733 6700 d 15 h bondari /kernel/trunk/test/mm/falloc2/ frame allocator test #2  
730 6701 d 12 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
729 6701 d 12 h jermar /kernel/trunk/generic/include/ In-array FIFO implementation.  
728 6703 d 7 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
727 6703 d 8 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
726 6703 d 8 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
724 6705 d 9 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6707 d 9 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 6707 d 11 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
716 6707 d 12 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6707 d 12 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
714 6707 d 12 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)		  
712 6707 d 13 h decky /kernel/trunk/ "Hello world" from user space :)  
711 6707 d 14 h decky /kernel/trunk/generic/src/mm/ fix wrong frame memory access  
710 6707 d 15 h vana /kernel/trunk/arch/ia64/include/mm/ VHPT entry  
707 6707 d 16 h decky /kernel/trunk/ allow setting ARCH from Makefile argument  
705 6707 d 17 h decky /kernel/trunk/ update phony targets  
704 6709 d 14 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.		  
703 6709 d 17 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().		  
702 6709 d 18 h jermar /kernel/trunk/arch/amd64/src/ Fix amd64 interrupt_handler to properly remove error code from stack before iretq.  
701 6712 d 7 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.		  
700 6712 d 16 h jermar /kernel/trunk/arch/sparc64/include/ Remove fmath.h
