/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? :-/

/kernel/trunk/arch/amd64/
Basic amd syscall support.
802

/kernel/trunk/arch/amd64/
Userspace now starts executing correctly.
800

/kernel/trunk/arch/amd64/include/
Split AMD interrupt.h from ia32 version.

Preliminary work on AMD userspace.

/kernel/trunk/arch/amd64/src/boot/
fix init_addr virtual address
797

palkovsky
/kernel/trunk/arch/mips32/
Fixed uspace address constants.
796

Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.
794

/kernel/trunk/
Added MIPS userspace. Currently can't make it work in gxemul.
793

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.
792

Page hash table architectures now use generic hash table to manage
mappings.
786
6707 d 19 h
bondari
/kernel/trunk/
frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
778

Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
769
6710 d 9 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
6710 d 14 h

/kernel/trunk/
Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
764
6710 d 19 h
palkovsky
/kernel/trunk/
Tested basic non-cached slab allocation.
763
6710 d 20 h
jermar
/kernel/trunk/
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
762
6710 d 21 h
palkovsky
/kernel/trunk/
Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
760

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.
758

sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.
