951	6632 d 8 h	decky	/kernel/trunk/arch/ppc32/	ppc32 boots again (temporarily)
940	6633 d 4 h	jermar	/kernel/trunk/	Get rid of unneeded macros. Their functionality has been replaced by the ELF loader.
934	6633 d 6 h	decky	/kernel/trunk/arch/ppc32/	remove all OpenFirmware bindings from ppc32 kernel code kernel now runs in real mode (ppc32)
867	6651 d 9 h	jermar	/kernel/trunk/	Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64. sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.
843	6657 d 3 h	palkovsky	/kernel/trunk/	Made powerpc to get on PearPC to the version print when compiled with -O1: - create proper memory zones - switch to real mode on boot TODO - kernel relocation during boot - autodetection of framebuffer settings (PCI?) - now includes hardcoded settings for PearPc.
833	6660 d 23 h	jermar	/kernel/trunk/arch/ppc32/include/mm/	Fix ppc32 to at least compile again.
823	6665 d 0 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
765	6671 d 2 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
763	6671 d 8 h	jermar	/kernel/trunk/	Modify frame.h to use shifting instead of multiplication and division. Define FRAME_WIDTH for all architectures.
760	6671 d 11 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.
756	6672 d 23 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	6685 d 1 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
703	6691 d 10 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().
569	6727 d 1 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
534	6731 d 4 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6731 d 4 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6743 d 8 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
391	6792 d 1 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	6792 d 12 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().
342	6814 d 10 h	jermar	/SPARTAN/trunk/arch/	Rename ppc port to ppc32.
