1968
6535 d 3 h
jermar
/tags/
Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.
1963
6535 d 3 h
jermar
/tags/0.1.1/
Tagging release 0.1.1
1070
6759 d 15 h
jermar
/kernel/trunk/
More checks for address space area conflicts.
1064
6760 d 0 h
palkovsky
/kernel/trunk/arch/amd64/
Cleanup of amd64 code.
1063
6760 d 1 h
palkovsky
/kernel/trunk/
Add support for more then 2GB of address space for AMD64.
977
6762 d 11 h
jermar
/kernel/trunk/
Add sys_mremap() syscall.
967
6762 d 14 h
palkovsky
/kernel/trunk/
Allowed userspace to include page.h.
940
6764 d 6 h
jermar
/kernel/trunk/
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
832
6794 d 2 h
jermar
/kernel/trunk/
Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.
831
6794 d 9 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
6795 d 8 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
6797 d 15 h
palkovsky
/kernel/trunk/arch/amd64/
Doc updates.
802
6798 d 2 h
palkovsky
/kernel/trunk/arch/amd64/
Userspace now starts executing correctly.
765
6802 d 4 h
jermar
/kernel/trunk/
Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
763
6802 d 10 h
jermar
/kernel/trunk/
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
760
6802 d 12 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
6804 d 1 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
6816 d 3 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
703
6822 d 12 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

sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
