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 Laurent Vivier (7): accel/tcg: add size paremeter in tlb_fill() target/m68k: add MC68040 MMU target/m68k: add Transparent Translation target/m68k: add index parameter to gen_load()/gen_store() and Co. target/m68k: add moves target/m68k: add pflush/ptest target/m68k: add HMP command "info tlb" accel/tcg/cputlb.c | 13 +- accel/tcg/softmmu_template.h | 14 +- accel/tcg/user-exec.c | 2 +- hmp-commands-info.hx | 2 +- include/exec/exec-all.h | 6 +- include/qom/cpu.h | 2 +- target/alpha/cpu.h | 2 +- target/alpha/helper.c | 4 +- target/alpha/mem_helper.c | 6 +- target/arm/cpu.c | 4 +- target/arm/op_helper.c | 4 +- target/cris/cpu.h | 2 +- target/cris/helper.c | 4 +- target/cris/op_helper.c | 6 +- target/hppa/cpu.h | 3 +- target/hppa/helper.c | 2 +- target/hppa/op_helper.c | 2 +- target/i386/cpu.h | 2 +- target/i386/excp_helper.c | 4 +- target/i386/mem_helper.c | 6 +- target/lm32/cpu.h | 2 +- target/lm32/helper.c | 2 +- target/lm32/op_helper.c | 6 +- target/m68k/cpu.c | 4 +- target/m68k/cpu.h | 145 +++++++++- target/m68k/helper.c | 604 +++++++++++++++++++++++++++++++++++++++++- target/m68k/helper.h | 2 + target/m68k/monitor.c | 22 ++ target/m68k/op_helper.c | 101 ++++++- target/m68k/qregs.def | 2 + target/m68k/translate.c | 247 ++++++++++++----- target/microblaze/cpu.h | 2 +- target/microblaze/helper.c | 4 +- target/microblaze/op_helper.c | 6 +- target/mips/helper.c | 2 +- target/mips/internal.h | 2 +- target/mips/op_helper.c | 10 +- target/moxie/cpu.h | 2 +- target/moxie/helper.c | 10 +- target/nios2/cpu.h | 2 +- target/nios2/helper.c | 6 +- target/nios2/mmu.c | 6 +- target/openrisc/cpu.h | 2 +- target/openrisc/mmu.c | 8 +- target/openrisc/mmu_helper.c | 6 +- target/ppc/cpu.h | 2 +- target/ppc/mmu_helper.c | 4 +- target/ppc/user_only_helper.c | 2 +- target/s390x/excp_helper.c | 4 +- target/s390x/internal.h | 2 +- target/s390x/mem_helper.c | 8 +- target/sh4/cpu.h | 2 +- target/sh4/helper.c | 4 +- target/sh4/op_helper.c | 6 +- target/sparc/cpu.h | 2 +- target/sparc/ldst_helper.c | 6 +- target/sparc/mmu_helper.c | 6 +- target/tilegx/cpu.c | 4 +- target/tricore/op_helper.c | 4 +- target/unicore32/cpu.h | 2 +- target/unicore32/helper.c | 2 +- target/unicore32/op_helper.c | 6 +- target/unicore32/softmmu.c | 2 +- target/xtensa/op_helper.c | 4 +- 64 files changed, 1166 insertions(+), 201 deletions(-) -- 2.14.3
