4691 5560 d 9 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4344 5672 d 6 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5672 d 6 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
3403 5899 d 17 h svoboda /branches/dynload/ Merge latest trunk changes into dynload  
2927 6021 d 17 h decky /branches/dynload/ added dynload branch  
2725 6120 d 13 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2721 6121 d 13 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2697 6142 d 14 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2467 6358 d 9 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6363 d 12 h jermar /trunk/ Merge arm32 into trunk.  
2089 6494 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6505 d 7 h jermar /trunk/ (c) versus (C)  
2007 6552 d 5 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.
 
1958 6587 d 14 h decky /trunk/kernel/arch/amd64/ amd64: adopt new IRQ interface  
1891 6626 d 5 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6626 d 16 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 6627 d 7 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 6630 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6695 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6702 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6723 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1511 6734 d 12 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1423 6740 d 14 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6743 d 10 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.
 
1070 6811 d 17 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1064 6812 d 3 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6812 d 3 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
977 6814 d 13 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6814 d 17 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
940 6816 d 8 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
832 6846 d 5 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6846 d 11 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
 
825 6847 d 10 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
808 6849 d 18 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
802 6850 d 5 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
765 6854 d 6 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6854 d 12 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
760 6854 d 15 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 6856 d 3 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 6868 d 5 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
