Hi; this is another target-arm pullreq. It's a big one but it's only two series: FEAT_MEC and FEAT_GCS.
thanks -- PMM The following changes since commit 94474a7733a57365d5a27efc28c05462e90e8944: Merge tag 'pull-loongarch-20251009' of https://github.com/gaosong715/qemu into staging (2025-10-09 07:59:29 -0700) are available in the Git repository at: https://gitlab.com/pm215/qemu.git tags/pull-target-arm-20251010 for you to fetch changes up to 00936783abf77ebb47a78312a2e6500c6a13d938: target/arm: Enable FEAT_MEC in -cpu max (2025-10-10 13:22:05 +0100) ---------------------------------------------------------------- target-arm queue: * Implement FEAT_GCS * Implement FEAT_MEC ---------------------------------------------------------------- Gustavo Romero (3): target/arm: Add a cpreg flag to indicate no trap in NV target/arm: Implement FEAT_MEC registers target/arm: Enable FEAT_MEC in -cpu max Pierrick Bouvier (1): tests/functional: update tests using TF-A/TF-RMM to support FEAT_GCS Richard Henderson (72): target/arm: Add isar feature test for FEAT_S1PIE, FEAT_S2PIE target/arm: Enable TCR2_ELx.PIE target/arm: Implement PIR_ELx, PIRE0_ELx, S2PIR_EL2 registers target/arm: Force HPD for stage2 translations target/arm: Cache NV1 early in get_phys_addr_lpae target/arm: Populate PIE in aa64_va_parameters target/arm: Implement get_S1prot_indirect target/arm: Implement get_S2prot_indirect target/arm: Expand CPUARMState.exception.syndrome to 64 bits target/arm: Expand syndrome parameter to raise_exception* target/arm: Implement dirtybit check for PIE target/arm: Enable FEAT_S1PIE and FEAT_S2PIE on -cpu max include/exec/memopidx: Adjust for 32 mmu indexes include/hw/core/cpu: Widen MMUIdxMap target/arm: Split out mmuidx.h from cpu.h target/arm: Convert arm_mmu_idx_to_el from switch to table target/arm: Remove unused env argument from regime_el target/arm: Convert regime_el from switch to table target/arm: Convert regime_has_2_ranges from switch to table target/arm: Remove unused env argument from regime_is_pan target/arm: Convert regime_is_pan from switch to table target/arm: Remove unused env argument from regime_is_user target/arm: Convert regime_is_user from switch to table target/arm: Convert arm_mmu_idx_is_stage1_of_2 from switch to table target/arm: Convert regime_is_stage2 to table target/arm: Introduce mmu indexes for GCS target/arm: Introduce regime_to_gcs target/arm: Support page protections for GCS mmu indexes target/arm: Implement gcs bit for data abort target/arm: Add GCS cpregs target/arm: Add GCS enable and trap levels to DisasContext target/arm: Implement FEAT_CHK target/arm: Make helper_exception_return system-only target/arm: Export cpsr_{read_for, write_from}_spsr_elx target/arm: Expand pstate to 64 bits target/arm: Add syndrome data for EC_GCS target/arm: Add arm_hcr_el2_nvx_eff target/arm: Use arm_hcr_el2_nvx_eff in access_nv1 target/arm: Split out access_nv1_with_nvx target/arm: Implement EXLOCKException for ELR_ELx and SPSR_ELx target/arm: Split {full,core}_a64_user_mem_index target/arm: Introduce delay_exception{_el} target/arm: Emit HSTR trap exception out of line target/arm: Emit v7m LTPSIZE exception out of line target/arm: Implement GCSSTR, GCSSTTR target/arm: Implement GCSB target/arm: Implement GCSPUSHM target/arm: Implement GCSPOPM target/arm: Implement GCSPUSHX target/arm: Implement GCSPOPX target/arm: Implement GCSPOPCX target/arm: Implement GCSSS1 target/arm: Implement GCSSS2 target/arm: Add gcs record for BL target/arm: Add gcs record for BLR target/arm: Add gcs record for BLR with PAuth target/arm: Load gcs record for RET target/arm: Load gcs record for RET with PAuth target/arm: Copy EXLOCKEn to EXLOCK on exception to the same EL target/arm: Implement EXLOCK check during exception return target/arm: Enable FEAT_GCS with -cpu max linux-user/aarch64: Implement prctls for GCS linux-user/aarch64: Allocate new gcs stack on clone linux-user/aarch64: Release gcs stack on thread exit linux-user/aarch64: Implement map_shadow_stack syscall target/arm: Enable GCSPR_EL0 for read in user-mode linux-user/aarch64: Inject SIGSEGV for GCS faults linux-user/aarch64: Generate GCS signal records linux-user/aarch64: Enable GCS in HWCAP tests/tcg/aarch64: Add gcsstr tests/tcg/aarch64: Add gcspushm tests/tcg/aarch64: Add gcsss docs/system/arm/emulation.rst | 7 + include/exec/memopidx.h | 9 +- include/hw/core/cpu.h | 7 +- linux-user/aarch64/gcs-internal.h | 38 ++ linux-user/aarch64/target_prctl.h | 96 +++++ linux-user/aarch64/target_signal.h | 1 + linux-user/qemu.h | 5 + target/arm/cpregs.h | 42 +- target/arm/cpu-features.h | 20 + target/arm/cpu.h | 253 ++---------- target/arm/internals.h | 151 ++----- target/arm/mmuidx-internal.h | 113 ++++++ target/arm/mmuidx.h | 241 ++++++++++++ target/arm/syndrome.h | 35 ++ target/arm/tcg/helper-a64.h | 5 +- target/arm/tcg/translate.h | 46 ++- tests/tcg/aarch64/gcs.h | 80 ++++ target/arm/tcg/a64.decode | 5 + accel/tcg/cputlb.c | 3 -
