VSID support (broken yet)
boot API change
cleanup		  
1726 6625 d 16 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)		  
1702 6629 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.

1511 6640 d 19 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1475 6642 d 11 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1423 6646 d 20 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1398 6652 d 13 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1388 6652 d 15 h bondari /kernel/trunk/arch/ppc32/include/mm/  
1374 6655 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1270 6672 d 12 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6672 d 14 h decky /kernel/trunk/ PHT Refill handler  
1215 6681 d 13 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1070 6717 d 23 h jermar /kernel/trunk/ More checks for address space area conflicts.  
977 6720 d 19 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
970 6720 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6720 d 23 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6721 d 14 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6721 d 18 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6722 d 15 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
934 6722 d 16 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6740 d 19 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 6746 d 13 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 6750 d 9 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6754 d 10 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
765 6760 d 12 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6760 d 18 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6760 d 21 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 6762 d 9 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 6774 d 11 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6780 d 20 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 6816 d 11 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6820 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6820 d 14 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6832 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6881 d 11 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 6881 d 22 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 6903 d 20 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
169 6926 d 11 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
