600	6743 d 7 h	jermar	/kernel/trunk/arch/mips32/	Different sizes of TLB on mips32. R4000 has 48 entries, 4kc has only 16 entries.
599	6743 d 8 h	jermar	/kernel/trunk/arch/mips32/	Fixes for mips32 invalidation functions.
594	6744 d 3 h	jermar	/kernel/trunk/	ptlb command (currently usable on mips32 only).
573	6745 d 4 h	palkovsky	/kernel/trunk/	Added MIPS ARC memory initializaiton.
534	6750 d 3 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6750 d 3 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6762 d 7 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
403	6805 d 2 h	jermar	/SPARTAN/trunk/arch/	Small improvement in pte_t type definition.
399	6807 d 23 h	jermar	/SPARTAN/trunk/	mips32 memory management work. TLB exceptions seem to be working on at least simics. msim handles TLB Refill and TLB Invalid exceptions well, but seems to skip writes to the mapped addressies in mm mapping test #1 (the data is not written and exception is not triggered).
396	6809 d 10 h	jermar	/SPARTAN/trunk/	Add mm/mapping1 test. (Will not make it past TLB Invalid exception on mips32.) Fixes in asid.c. Make TLB register types union with __u32 value. Implement tlb_invalidate() for mips32. (TLB invalidation and shootdown path will have to be revised.)
394	6810 d 1 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	6811 d 0 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	6811 d 11 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	6833 d 9 h	jermar	/SPARTAN/trunk/	Rename mips port to mips32.
329	6835 d 5 h	palkovsky	/SPARTAN/trunk/	Basic changes to boot it on SGI Indy.
319	6838 d 12 h	jermar	/SPARTAN/trunk/arch/mips/	Copyright notices changes.
317	6838 d 13 h	palkovsky	/SPARTAN/trunk/	MIPS exception now saves all necesssary information only on stack.
313	6838 d 23 h	palkovsky	/SPARTAN/trunk/arch/	MIPS bug fixes. Added usermode to MIPS, unfortunately impossible to test until MM is ready.
306	6839 d 13 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	6847 d 10 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.
