This series introduces the MC68040 MMU.
But first of all, we need to modify the prototype
of tlb_fill() and handle_mmu_fault handler to pass
the size of the access. MC68040 stores this value
in the exception stack frame.
Following patches add:
- MMU page table and fault handlers,
- Transparent Translation Registers
- instruction "moves" to move data
between user and kernel space
- instructions pflush/ptest, to flush TLB and
convert virtual address to physical address
- "info tlb" HMP command
I have tested it doesn't break QEMU linux-user mode
emulation and coldfire softmmu machine.
With the help of these patches I'm able to start
a debian etch-m68k, but the following patches
are still missing in master:
- m68k softfloat series
- Quadra 800 machine emulation series
(VIA emulation, Nubus emulation,
ESCC control/data address bit selector,
video card emulation, ESP Pseudo-DMA,
SWIM floppy controller, Apple Sound Chip
emulation, and some big-endian fixes for
dp8393x)
v2: use "0" for the access size when we don't know
the size of the access
move mmu_fault to CPUM68KState
set TARGET_PAGE_BITS to 12 to avoid tlb_add_large_page() path
use -page_size to mask address instead of TARGET_PAGE_MASK
add ACCESS_DEBUG to not update page table USED/MODIFIED bits
on gdb access
rename ACCESS_INT to ACCESS_DATA
add index parameter to gen_load()/gen_store()
copy bit 2 of SFC and DFC to tb->flags to
inline memory access in moves decoder
change ACCESS_PTEST value because of new ACCESS_DEBUG
