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. This could still be continued which I might do in the future but I had enough of it for now. v6: - Finish breaking up ppc_jumbo_xlate by MMU model as the TODO comment said and remove it completely - Add some more small clean ups v5: - drop sc patches from this series - eliminate uninit warning work arounds and also get rid of get_physical_address_wtlb() (one memset is still needed temporarily but can be removed at the end) - use function instead of macro v4: - Add a (probably redundant) check for MPC8xx case in ppc_xlate so we don't have to care about it in lower levels - Detangle BookE related functions from mmu_ctx_t to avoid some used uninit work arounds and allow these to be moved out to mmu-booke.c - Some other tweaks asked during 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 Dr. David Alan Gilbert (1): target/ppc: Remove unused struct 'mmu_ctx_hash32' BALATON Zoltan (47): 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: 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: Don't use mmu_ctx_t for mmu40x_get_physical_address() target/ppc/mmu_common.c: Don't use mmu_ctx_t in mmubooke_get_physical_address() target/ppc/mmu_common.c: Don't use mmu_ctx_t in mmubooke206_get_physical_address() 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: Simplify ppc_booke_xlate() part 1 target/ppc/mmu_common.c: Simplify ppc_booke_xlate() part 2 target/ppc/mmu_common.c: Split off real mode handling from get_physical_address_wtlb() target/ppc/mmu_common.c: Split off 40x cases from ppc_jumbo_xlate() target/ppc/mmu_common.c: Transform ppc_jumbo_xlate() into ppc_6xx_xlate() target/ppc/mmu_common.c: Move mmu_ctx_t type to mmu_common.c target/ppc/mmu_common.c: Remove pte_update_flags() 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 function to check for page protection bit target/ppc: Move out BookE and related MMU functions from mmu_common.c target/ppc/mmu_common.c: Remove local name for a constant target/ppc/mmu_common.c: Remove single use local variable target/ppc/mmu_common.c: Remove single use local variable target/ppc/mmu_common.c: Remove another single use local target/ppc/mmu_common.c: Remove yet another single use local target/ppc/mmu_common.c: Return directly in ppc6xx_tlb_pte_check() target/ppc/mmu_common.c: Simplify ppc6xx_tlb_pte_check() target/ppc/mmu_common.c: Remove unused field from mmu_ctx_t target/ppc/mmu_common.c: Remove hash field from mmu_ctx_t target/ppc/mmu_common.c: Remove nx field from mmu_ctx_t target/ppc/mmu_common.c: Convert local variable to bool target/ppc/mmu_common.c: Remove single use local variable target/ppc/mmu_common.c: Simplify a switch statement hw/ppc/pegasos2.c | 2 +- target/ppc/cpu.h | 9 +- target/ppc/cpu_init.c | 70 +-- target/ppc/helper.h | 2 - target/ppc/helper_regs.c | 1 - target/ppc/internal.h | 75 ++- target/ppc/meson.build | 1 + target/ppc/mmu-booke.c | 531 ++++++++++++++++ target/ppc/mmu-booke.h | 17 + target/ppc/mmu-hash32.c | 60 +- target/ppc/mmu-hash64.c | 2 +- target/ppc/mmu-radix64.c | 5 +- target/ppc/mmu_common.c | 1289 ++++++++++---------------------------- target/ppc/mmu_helper.c | 37 +- 14 files changed, 954 insertions(+), 1147 deletions(-) create mode 100644 target/ppc/mmu-booke.c create mode 100644 target/ppc/mmu-booke.h
