3240 5992 d 11 h decky / move unfinished ObjC support to a separate branch  
2467 6406 d 4 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6411 d 7 h jermar /trunk/ Merge arm32 into trunk.  
2125 6528 d 2 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6542 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6553 d 1 h jermar /trunk/ (c) versus (C)  
1888 6678 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1851 6702 d 8 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1787 6743 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6750 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6771 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1423 6788 d 8 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1108 6854 d 0 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
977 6862 d 8 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
832 6893 d 23 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
793 6898 d 7 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
760 6902 d 9 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 6903 d 22 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.		  
755 6904 d 21 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
684 6927 d 7 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
