2089 6384 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6395 d 16 h jermar /trunk/ (c) versus (C)  
2007 6442 d 15 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
1891 6516 d 15 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6517 d 1 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1889 6517 d 17 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6520 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6585 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6592 d 20 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1730 6609 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup		  
1726 6609 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)		  
1702 6613 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1609 6620 d 23 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1511 6624 d 22 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1475 6626 d 14 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1423 6630 d 23 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1398 6636 d 16 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1388 6636 d 18 h bondari /kernel/trunk/arch/ppc32/include/mm/  
1374 6639 d 13 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1270 6656 d 16 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6656 d 17 h decky /kernel/trunk/ PHT Refill handler  
1215 6665 d 17 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1070 6702 d 3 h jermar /kernel/trunk/ More checks for address space area conflicts.  
977 6704 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
970 6705 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6705 d 2 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6705 d 17 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6705 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6706 d 18 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
934 6706 d 19 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6724 d 22 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 6730 d 16 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 6734 d 12 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6738 d 13 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
765 6744 d 16 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6744 d 22 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6745 d 0 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 6746 d 13 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 6758 d 15 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6765 d 0 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().
