Rev	Age	Author	Path	Log message
2131	6441 d 2 h	decky	/branches/	add development branches
2071	6506 d 23 h	jermar	/trunk/	(c) versus (C)
1888	6632 d 2 h	jermar	/trunk/	C99 compliant header guards (hopefully) everywhere in the kernel. Formatting and indentation changes. Small improvements in sparc64.
1787	6697 d 1 h	decky	/	move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
1705	6724 d 8 h	cejka	/kernel/trunk/	Added file with modules definitions and descriptions. We are able to change modules order and their description in one place.
1702	6725 d 5 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
830	6848 d 5 h	jermar	/kernel/trunk/	Make ASID FIFO for mips32 be allocated statically. Make ASID FIFO for sparc64 and ia64 be allocated dynamically. Fix ia64 to call asid_fifo_init(). All three architectures now call asid_fifo_init() from as_arch_init().
756	6857 d 19 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
727	6869 d 21 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
703	6876 d 6 h	jermar	/kernel/trunk/	Memory management work. - vm.* -> as.* (as like address space is, imho, more fitting) - Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid(). - Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault(). - Add high-level page fault handler as_page_fault(). - Add as_area_load_mapping().
595	6909 d 23 h	palkovsky	/kernel/trunk/	Fixed bug in vm.c that turned off preemption. Found in versions 390:391.
534	6915 d 23 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6916 d 0 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6928 d 4 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
413	6963 d 20 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.
397	6974 d 9 h	jermar	/SPARTAN/trunk/	Small changes to mips32 mm. Small changes in mm mapping test #1.
396	6975 d 6 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.)
391	6976 d 21 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.
