Supercedes: 20220412003326.588530-1-richard.hender...@linaro.org ("target/arm: 8 new features, A76 and N1")
Changes for v3: * More field updates for H.a. This is not nearly complete, but what I've encountered so far as I've begun implementing SME. * Use bool instead of uint32_t for env->{aarch64,thumb}. I had anticipated other changes for implementing PSTATE.{SM,FA}, but dropped those; these seemed like worth keeping. * Use tcg_constant_* more -- got stuck on this while working on... * Lots of cleanups to ARMCPRegInfo. * Discard unreachable cpregs when ELx not available. * Transform EL2 regs to RES0 when EL3 present but EL2 isn't. This greatly simplifies registration of cpregs for new features. Changes contextidr_el2, minimal_ras_reginfo, scxtnum_reginfo within this patch set; other uses coming for SME. r~ Richard Henderson (60): tcg: Add tcg_constant_ptr target/arm: Update ISAR fields for ARMv8.8 target/arm: Update SCR_EL3 bits to ARMv8.8 target/arm: Update SCTLR bits to ARMv9.2 target/arm: Change DisasContext.aarch64 to bool target/arm: Change CPUArchState.aarch64 to bool target/arm: Extend store_cpu_offset to take field size target/arm: Change DisasContext.thumb to bool target/arm: Change CPUArchState.thumb to bool target/arm: Remove fpexc32_access target/arm: Split out set_btype_raw target/arm: Split out gen_rebuild_hflags target/arm: Use tcg_constant in translate-a64.c target/arm: Simplify GEN_SHIFT in translate.c target/arm: Simplify gen_sar target/arm: Simplify aa32 DISAS_WFI target/arm: Use tcg_constant in translate.c target/arm: Use tcg_constant in translate-m-nocp.c target/arm: Use tcg_constant in translate-neon.c target/arm: Use smin/smax for do_sat_addsub_32 target/arm: Use tcg_constant in translate-sve.c target/arm: Use tcg_constant in translate-vfp.c target/arm: Use tcg_constant_i32 in translate.h target/arm: Split out cpregs.h target/arm: Reorg CPAccessResult and access_check_cp_reg target/arm: Replace sentinels with ARRAY_SIZE in cpregs.h target/arm: Make some more cpreg data static const target/arm: Reorg ARMCPRegInfo type field bits target/arm: Change cpreg access permissions to enum target/arm: Name CPState type target/arm: Name CPSecureState type target/arm: Update sysreg fields when redirecting for E2H target/arm: Store cpregs key in the hash table directly target/arm: Cleanup add_cpreg_to_hashtable target/arm: Handle cpreg registration for missing EL target/arm: Drop EL3 no EL2 fallbacks target/arm: Merge zcr reginfo target/arm: Add isar predicates for FEAT_Debugv8p2 target/arm: Adjust definition of CONTEXTIDR_EL2 target/arm: Move cortex impdef sysregs to cpu_tcg.c target/arm: Update qemu-system-arm -cpu max to cortex-a57 target/arm: Set ID_DFR0.PerfMon for qemu-system-arm -cpu max target/arm: Split out aa32_max_features target/arm: Annotate arm_max_initfn with FEAT identifiers target/arm: Use field names for manipulating EL2 and EL3 modes target/arm: Enable FEAT_Debugv8p2 for -cpu max target/arm: Enable FEAT_Debugv8p4 for -cpu max target/arm: Add isar_feature_{aa64,any}_ras target/arm: Add minimal RAS registers target/arm: Enable SCR and HCR bits for RAS target/arm: Implement virtual SError exceptions target/arm: Implement ESB instruction target/arm: Enable FEAT_RAS for -cpu max target/arm: Enable FEAT_IESB for -cpu max target/arm: Enable FEAT_CSV2 for -cpu max target/arm: Enable FEAT_CSV2_2 for -cpu max target/arm: Enable FEAT_CSV3 for -cpu max target/arm: Enable FEAT_DGH for -cpu max target/arm: Define cortex-a76 target/arm: Define neoverse-n1 docs/system/arm/emulation.rst | 10 + docs/system/arm/virt.rst | 2 + include/tcg/tcg.h | 2 + target/arm/cpregs.h | 459 +++++++++++++++++ target/arm/cpu.h | 475 ++++-------------- target/arm/helper.h | 1 + target/arm/internals.h | 16 + target/arm/syndrome.h | 5 + target/arm/translate-a32.h | 13 +- target/arm/translate.h | 17 +- target/arm/a32.decode | 16 +- target/arm/t32.decode | 18 +- hw/arm/pxa2xx.c | 2 +- hw/arm/pxa2xx_pic.c | 2 +- hw/arm/sbsa-ref.c | 2 + hw/arm/virt.c | 2 + hw/intc/arm_gicv3_cpuif.c | 6 +- hw/intc/arm_gicv3_kvm.c | 3 +- linux-user/arm/cpu_loop.c | 2 +- target/arm/cpu.c | 88 ++-- target/arm/cpu64.c | 349 +++++++------ target/arm/cpu_tcg.c | 232 ++++++--- target/arm/gdbstub.c | 5 +- target/arm/helper-a64.c | 4 +- target/arm/helper.c | 897 ++++++++++++++++++---------------- target/arm/hvf/hvf.c | 2 +- target/arm/m_helper.c | 6 +- target/arm/op_helper.c | 113 +++-- target/arm/translate-a64.c | 395 ++++++--------- target/arm/translate-m-nocp.c | 12 +- target/arm/translate-neon.c | 21 +- target/arm/translate-sve.c | 207 +++----- target/arm/translate-vfp.c | 76 +-- target/arm/translate.c | 400 +++++++-------- 34 files changed, 2026 insertions(+), 1834 deletions(-) create mode 100644 target/arm/cpregs.h -- 2.25.1
