1423	6735 d 5 h	jermar	/kernel/trunk/	Update page fault handlers to distinguish between different access modes that had caused the page fault.
1411	6738 d 1 h	jermar	/kernel/trunk/	Modify the hierarchy of page fault handlers to pass access mode that caused the fault. Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC to as_page_fault(), depending on the cause of the fault.
977	6809 d 4 h	jermar	/kernel/trunk/	Add sys_mremap() syscall.
967	6809 d 8 h	palkovsky	/kernel/trunk/	Allowed userspace to include page.h.
957	6809 d 22 h	decky	/kernel/trunk/arch/	run ppc32 kernel above 2 GB
832	6840 d 20 h	jermar	/kernel/trunk/	Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.
831	6841 d 2 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	6842 d 1 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	6848 d 21 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
760	6849 d 5 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	6908 d 23 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6908 d 23 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6921 d 3 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
391	6969 d 20 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.
300	6999 d 6 h	palkovsky	/SPARTAN/trunk/arch/ia32/	Backported AMD64 linker and boot changes back to IA32.
169	7014 d 20 h	jermar	/SPARTAN/trunk/arch/	For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
135	7046 d 4 h	jermar	/SPARTAN/trunk/	Fix setters of page table attributes for both IA-32 and MIPS.
120	7065 d 19 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.
119	7066 d 21 h	jermar	/SPARTAN/trunk/	Start with generic 4-level page table interface. Usual cleanup.
105	7093 d 18 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.
