/kernel/trunk/arch/amd64/src/smp/
Simics GS patch even in SMP.
808

palkovsky
/kernel/trunk/arch/amd64/
Doc updates.

/kernel/trunk/arch/amd64/src/boot/
I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics.

/kernel/trunk/arch/amd64/
Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/
803

/kernel/trunk/arch/amd64/
Basic amd syscall support.
802
6759 d 20 h
palkovsky
/kernel/trunk/arch/amd64/
Userspace now starts executing correctly.
800
6759 d 21 h
palkovsky
/kernel/trunk/arch/amd64/include/
Split AMD interrupt.h from ia32 version.

Preliminary work on AMD userspace.
798

/kernel/trunk/arch/amd64/src/boot/
fix init_addr virtual address
793
6760 d 3 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.
778
6761 d 23 h

Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
769
6763 d 16 h
palkovsky
/kernel/trunk/
SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception.
765
6763 d 21 h
jermar
/kernel/trunk/
Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
763
6764 d 3 h
jermar
/kernel/trunk/
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
760
6764 d 5 h

/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
6765 d 18 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
6766 d 17 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.
727
6777 d 20 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
717
6781 d 23 h
decky
/kernel/trunk/
remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
703
6784 d 5 h

/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().
