2071 6497 d 2 h jermar /trunk/ (c) versus (C)  
2007 6544 d 1 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 6579 d 9 h decky /trunk/kernel/arch/amd64/ amd64: adopt new IRQ interface  
1888 6622 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6687 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6694 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6715 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1423 6732 d 9 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6735 d 6 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.
 
1064 6803 d 22 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6803 d 23 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
977 6806 d 9 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6806 d 12 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
832 6838 d 0 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6838 d 7 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 6839 d 6 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 6841 d 13 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
765 6846 d 2 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
760 6846 d 10 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.
 
534 6906 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
