It also contains some other changes that I've come up with while working on this. The Simplify ppc_booke_xlate() part 1 and part 2 patches could be squashed together but left them separate for easier review. v3: - Address review comments from Nick - Rebase on master - Squashed some patches together - Add some more patches I've done since last version v2: - Fix user mode issue in patch 1 by keeping old behaviour for user mode - Add some more MMU clean up patches Regards, BALATON Zoltan BALATON Zoltan (33): target/ppc: Fix gen_sc to use correct nip target/ppc: Move patching nip from exception handler to helper_scv target/ppc: Simplify syscall exception handlers target/ppc: Remove unused helper target/ppc/mmu_common.c: Move calculation of a value closer to its usage target/ppc/mmu_common.c: Remove unneeded local variable target/ppc/mmu_common.c: Simplify checking for real mode target/ppc/mmu_common.c: Drop cases for unimplemented MPC8xx MMU target/ppc/mmu_common.c: Introduce mmu6xx_get_physical_address() target/ppc/mmu_common.c: Move else branch to avoid large if block target/ppc/mmu_common.c: Move some debug logging target/ppc/mmu_common.c: Eliminate ret from mmu6xx_get_physical_address() target/ppc/mmu_common.c: Split out BookE cases before checking real mode target/ppc/mmu_common.c: Split off real mode cases in get_physical_address_wtlb() target/ppc/mmu_common.c: Inline and remove check_physical() target/ppc/mmu_common.c: Simplify mmubooke_get_physical_address() target/ppc/mmu_common.c: Simplify mmubooke206_get_physical_address() target/ppc/mmu_common.c: Fix misindented qemu_log_mask() calls target/ppc/mmu_common.c: Deindent ppc_jumbo_xlate() target/ppc/mmu_common.c: Replace hard coded constants in ppc_jumbo_xlate() target/ppc/mmu_common.c: Make get_physical_address_wtlb() static target/ppc: Remove pp_check() and reuse ppc_hash32_pp_prot() target/ppc/mmu_common.c: Remove BookE from direct store handling target/ppc/mmu_common.c: Split off BookE handling from ppc_jumbo_xlate() target/ppc/mmu_common.c: Remove BookE handling from get_physical_address_wtlb() target/ppc/mmu_common.c: Simplify ppc_booke_xlate() part 1 target/ppc/mmu_common.c: Simplify ppc_booke_xlate() part 2 target/ppc/mmu_common.c: Move BookE MMU functions together target/ppc: Remove id_tlbs flag from CPU env target/ppc: Split off common embedded TLB init target/ppc/mmu-hash32.c: Drop a local variable target/ppc/mmu-radix64.c: Drop a local variable target/ppc: Add a macro to check for page protection bit hw/ppc/pegasos2.c | 2 +- target/ppc/cpu.h | 1 - target/ppc/cpu_init.c | 69 ++- target/ppc/excp_helper.c | 67 +-- target/ppc/helper.h | 2 - target/ppc/helper_regs.c | 1 - target/ppc/internal.h | 72 +-- target/ppc/mmu-hash32.c | 54 +-- target/ppc/mmu-hash64.c | 2 +- target/ppc/mmu-radix64.c | 5 +- target/ppc/mmu_common.c | 954 +++++++++++++++++---------------------- target/ppc/mmu_helper.c | 36 +- target/ppc/translate.c | 21 +- 13 files changed, 517 insertions(+), 769 deletions(-)
