832	6656 d 6 h	jermar	/kernel/trunk/	Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.
831	6656 d 12 h	jermar	/kernel/trunk/	Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings. This helps to distinguish valid entries from not present entries with 0 content (i.e. not present entries with PFN 0 and other bits cleared).
825	6657 d 11 h	jermar	/kernel/trunk/	Remove WAKEUP_IPI stuff. Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32. Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
765	6664 d 7 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
760	6664 d 16 h	jermar	/kernel/trunk/	mips32 is not supposed to allocate page table. This is done by the generic code now. Remove PTL0 pointer as it is not needed. Remove GET_PTL0_ADDRESS from kernel. Update sparc64 comments in barrier.h.
534	6724 d 9 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6724 d 9 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6736 d 13 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
403	6779 d 8 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
394	6784 d 7 h	jermar	/SPARTAN/trunk/arch/mips32/	MIPS32 memory management work. Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14). Introduce two new bits in pte_t (i.e. 'a' and 'w'). Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)
391	6785 d 6 h	jermar	/SPARTAN/trunk/	mips32 memory management work. TLB Refill Exception implemented (passed basic testing). Remove bit g from struct entry_hi. Add generic find_mapping(). Add asid to vm_t type, define asid_t to hide architecture specific differences. Implement ASID allocation for mips32, dummy for other architectures. Add THE->vm (a.k.a. VM). Add vm_install_arch(). Move pte_t definition to arch/types.h on each architecture. Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14. Fix tlb_init_arch() to initialize all entries. Other. Remove unnecessary header files from arch.h Add missing headers here and there. Remove two unnecessary ld flags from mips32 makefile.
341	6807 d 15 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
319	6812 d 18 h	jermar	/SPARTAN/trunk/arch/mips/	Copyright notices changes.
306	6813 d 20 h	palkovsky	/SPARTAN/trunk/	Fixed mips boot process. On interrupt saving registers, save $lo, $hi. Add interrupt naming to asm files (mips). Save only necessary registers on context switch (see mips ABI). Fixed copyright info.
177	6821 d 16 h	jermar	/SPARTAN/trunk/	Add some comments to IA-32 src/boot/boot.S and src/smp.S. Make the boot stack start on page boundary. This is required by get_stack_base(). Define 'THE' macro. Implement preemption_disable() and preemption_enable(). Add memory barrier macros. IA-32 macros need support for older processors. Non IA-32 macros are dummy. Reduction of many #include paths.
169	6830 d 6 h	jermar	/SPARTAN/trunk/arch/	For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
135	6861 d 14 h	jermar	/SPARTAN/trunk/	Fix setters of page table attributes for both IA-32 and MIPS.
125	6866 d 6 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
121	6867 d 6 h	jermar	/SPARTAN/trunk/	Begin MIPS implementation of 4-level page table interface. Add email address to each item in doc/AUTHORS. Correct type names in comments in mm/vm.c. Introduce ptl0 pointer in vm_t.
120	6881 d 5 h	jermar	/SPARTAN/trunk/	Generic 4-level page tables interface & implementation (review & test). Implement more architecture dependant macros on IA-32. Provide fake implementation on IA-64 and MIPS. Convert map_page_to_frame() to use the new interface. Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
