VSID support (broken yet)
boot API change
cleanup		  
1726 6563 d 16 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)		  
1702 6567 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.

1511 6578 d 18 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1475 6580 d 10 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1423 6584 d 20 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1398 6590 d 13 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1388 6590 d 14 h bondari /kernel/trunk/arch/ppc32/include/mm/  
1374 6593 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1270 6610 d 12 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6610 d 14 h decky /kernel/trunk/ PHT Refill handler  
1215 6619 d 13 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1070 6655 d 23 h jermar /kernel/trunk/ More checks for address space area conflicts.  
977 6658 d 19 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
970 6658 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6658 d 22 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6659 d 13 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6659 d 18 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6660 d 14 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
934 6660 d 16 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6678 d 18 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 6684 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 6688 d 8 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6692 d 10 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
765 6698 d 12 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6698 d 18 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6698 d 20 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 6700 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 6712 d 11 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6718 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 6754 d 10 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6758 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6758 d 14 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6770 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6819 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 6819 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 6841 d 19 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
169 6864 d 11 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().
