394	6840 d 10 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	6841 d 9 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.
389	6841 d 20 h	jermar	/SPARTAN/trunk/	MIPS work. Fix some name inconsistencies between cp0 functions' declarations and definitions. Add and implement tlb_init_arch(). Add tlb_modified() exception handler. Other architectures: add dummy tlb_init_arch().
341	6863 d 18 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
329	6865 d 14 h	palkovsky	/SPARTAN/trunk/	Basic changes to boot it on SGI Indy.
319	6868 d 21 h	jermar	/SPARTAN/trunk/arch/mips/	Copyright notices changes.
317	6868 d 22 h	palkovsky	/SPARTAN/trunk/	MIPS exception now saves all necesssary information only on stack.
313	6869 d 8 h	palkovsky	/SPARTAN/trunk/arch/	MIPS bug fixes. Added usermode to MIPS, unfortunately impossible to test until MM is ready.
306	6869 d 23 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	6877 d 20 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	6886 d 9 h	jermar	/SPARTAN/trunk/arch/	For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
147	6916 d 17 h	jermar	/SPARTAN/trunk/arch/	Add missing memory_init.h files for IA-64 and MIPS architectures. Fix typo in IA-32's memory_init.h.
135	6917 d 18 h	jermar	/SPARTAN/trunk/	Fix setters of page table attributes for both IA-32 and MIPS.
134	6917 d 18 h	decky	/SPARTAN/trunk/arch/mips/include/mm/	Add missing asid.h
125	6922 d 10 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
121	6923 d 9 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	6937 d 8 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.
105	6965 d 8 h	jermar	/SPARTAN/trunk/	Big changes in IA-32 address space map. Now the kernel is mapped above 0x80000000. Finally! Userspace address space starts at 0x00000000. Changes in many places. This improvement temporarily breaks SMP and most likely also other stuff. Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32. Changes in linker script. Changes required because of the above. Do not patch hardcoded_* variables but assign to them instead. Cosmetic changes here and there.
1	7069 d 14 h	jermar	/SPARTAN/	Initial import
