492	6746 d 9 h	jermar	/SPARTAN/trunk/	Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find(). New names should make it more apparent that these two belong together.
430	6766 d 9 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
413	6781 d 8 h	jermar	/SPARTAN/trunk/	Rename cpu_priority_{high\|low\|restore\|read} functions to interrupts_{disable\|enable\|restore\|read}. Rename pri_t to ipl_t (Interrupt Priority Level). Rename thread_t::pri to thread_t::priority.
391	6794 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.
257	6825 d 22 h	palkovsky	/SPARTAN/trunk/	Added basic FPU context (not working). Added CPU utilities from ia32 Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.
236	6827 d 15 h	jermar	/SPARTAN/trunk/src/	Add missing header into kinit.c. Do not use PA2KA() on dst_ptl0.
227	6827 d 17 h	jermar	/SPARTAN/trunk/	Add couple of assertions CPU != NULL. Change type of nrdy from int to count_t. Rewrite halt() to avoid page fault when CPU == NULL.
205	6828 d 22 h	jermar	/SPARTAN/trunk/	Get rid of memcopy(). All we now have is memcpy() and _memcpy(). memcpy() is defined to be builtin. Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
198	6829 d 10 h	jermar	/SPARTAN/trunk/	Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy. Cleanup.
195	6829 d 12 h	vana	/SPARTAN/trunk/	1) memcopy and _memcopy functions rewriten to ANSI C norm. 2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions 3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
168	6839 d 10 h	jermar	/SPARTAN/trunk/	Add type cast to __address in vm_create(). This seems to fix the problem with userspace. Looks like KA2PA() returned wrong address when applied on pte_t *. Uncomment panic() in gp_fault(). Get rid of cli and sti in userspace code.
167	6840 d 18 h	jermar	/SPARTAN/trunk/	Switch over to per vm_t page tables. (breaks ia32 userspace) Define dummy memcopy() for amd64 and ppc to satisfy compiler. Get rid of problematic #include <arch/mm/page.h> in mm/page.h. Indentation fixes and small changes here and there.
121	6876 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.
115	6911 d 8 h	jermar	/SPARTAN/trunk/	Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file. Gain both better speed and size.
72	6940 d 11 h	decky	/SPARTAN/trunk/	size_t usage const qualifier code cleanup
68	6940 d 12 h	decky	/SPARTAN/trunk/	NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode indentation fixes, ASSERTs
35	6950 d 20 h	jermar	/SPARTAN/trunk/	Early support for IA-64 architecture.
31	6955 d 15 h	jermar	/SPARTAN/trunk/	Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation. The implementation is a variant of the CMU TLB consistency algorithm. Very inefficient implementation of a very inefficient (but correct) algorithm.
6	7018 d 23 h	jermar	/SPARTAN/trunk/	shootdown vs. shutdown
5	7019 d 10 h	jermar	/SPARTAN/trunk/	TLB shootdown.
