Version 8 incorporates quite a bit of review (thanks, PMM): * Include HCR_DCT in the HCR_EL2 update. * Use a separate decode function for ADDG/SUBG. * Use the system arm_cpu_do_unaligned_access for user-only as well. * Fix alignment for LDG. * Fix no-fault for mte_probe1. * Rearrage how tagged pages are recorded.
and perhaps most visibly, for those tracking the kernel patches: * Add arm,armv8.5-memtag to the dtb. r~ In need of review: 0010-target-arm-Revise-decoding-for-disas_add_sub_imm.patch 0011-target-arm-Implement-the-ADDG-SUBG-instructions.patch 0014-target-arm-Define-arm_cpu_do_unaligned_access-for.patch 0015-target-arm-Implement-LDG-STG-ST2G-instructions.patch 0025-target-arm-Implement-helper_mte_check1.patch 0028-target-arm-Use-mte_checkN-for-sve-unpredicated-lo.patch 0029-target-arm-Use-mte_checkN-for-sve-unpredicated-st.patch 0030-target-arm-Use-mte_check1-for-sve-LD1R.patch 0031-target-arm-Tidy-trans_LD1R_zpri.patch 0032-target-arm-Add-arm_tlb_bti_gp.patch 0033-target-arm-Add-mte-helpers-for-sve-scalar-int-loa.patch 0034-target-arm-Add-mte-helpers-for-sve-scalar-int-sto.patch 0035-target-arm-Add-mte-helpers-for-sve-scalar-int-ff-.patch 0036-target-arm-Handle-TBI-for-sve-scalar-int-memory-o.patch 0037-target-arm-Add-mte-helpers-for-sve-scatter-gather.patch 0038-target-arm-Complete-TBI-clearing-for-user-only-fo.patch 0041-target-arm-Always-pass-cacheattr-to-get_phys_addr.patch 0042-target-arm-Cache-the-Tagged-bit-for-a-page-in-Mem.patch 0043-target-arm-Create-tagged-ram-when-MTE-is-enabled.patch 0044-target-arm-Add-allocation-tag-storage-for-system-.patch 0045-target-arm-Enable-MTE.patch Richard Henderson (45): target/arm: Add isar tests for mte target/arm: Improve masking of SCR RES0 bits target/arm: Add support for MTE to SCTLR_ELx target/arm: Add support for MTE to HCR_EL2 and SCR_EL3 target/arm: Rename DISAS_UPDATE to DISAS_UPDATE_EXIT target/arm: Add DISAS_UPDATE_NOCHAIN target/arm: Add MTE system registers target/arm: Add MTE bits to tb_flags target/arm: Implement the IRG instruction target/arm: Revise decoding for disas_add_sub_imm target/arm: Implement the ADDG, SUBG instructions target/arm: Implement the GMI instruction target/arm: Implement the SUBP instruction target/arm: Define arm_cpu_do_unaligned_access for user-only target/arm: Implement LDG, STG, ST2G instructions target/arm: Implement the STGP instruction target/arm: Restrict the values of DCZID.BS under TCG target/arm: Simplify DC_ZVA target/arm: Implement the LDGM, STGM, STZGM instructions target/arm: Implement the access tag cache flushes target/arm: Move regime_el to internals.h target/arm: Move regime_tcr to internals.h target/arm: Add gen_mte_check1 target/arm: Add gen_mte_checkN target/arm: Implement helper_mte_check1 target/arm: Implement helper_mte_checkN target/arm: Add helper_mte_check_zva target/arm: Use mte_checkN for sve unpredicated loads target/arm: Use mte_checkN for sve unpredicated stores target/arm: Use mte_check1 for sve LD1R target/arm: Tidy trans_LD1R_zpri target/arm: Add arm_tlb_bti_gp target/arm: Add mte helpers for sve scalar + int loads target/arm: Add mte helpers for sve scalar + int stores target/arm: Add mte helpers for sve scalar + int ff/nf loads target/arm: Handle TBI for sve scalar + int memory ops target/arm: Add mte helpers for sve scatter/gather memory ops target/arm: Complete TBI clearing for user-only for SVE target/arm: Implement data cache set allocation tags target/arm: Set PSTATE.TCO on exception entry target/arm: Always pass cacheattr to get_phys_addr target/arm: Cache the Tagged bit for a page in MemTxAttrs target/arm: Create tagged ram when MTE is enabled target/arm: Add allocation tag storage for system mode target/arm: Enable MTE include/hw/arm/boot.h | 3 + target/arm/cpu.h | 50 +- target/arm/helper-a64.h | 16 + target/arm/helper-sve.h | 488 ++++++++++++ target/arm/helper.h | 2 + target/arm/internals.h | 153 +++- target/arm/translate-a64.h | 5 + target/arm/translate.h | 23 +- hw/arm/boot.c | 12 +- hw/arm/virt.c | 57 +- target/arm/cpu.c | 77 +- target/arm/cpu64.c | 1 + target/arm/helper-a64.c | 94 +-- target/arm/helper.c | 423 +++++++--- target/arm/m_helper.c | 11 +- target/arm/mte_helper.c | 901 +++++++++++++++++++++ target/arm/op_helper.c | 16 + target/arm/sve_helper.c | 616 +++++++++++--- target/arm/tlb_helper.c | 13 +- target/arm/translate-a64.c | 652 +++++++++++++-- target/arm/translate-sve.c | 1366 +++++++++++++++++++++----------- target/arm/translate-vfp.inc.c | 2 +- target/arm/translate.c | 16 +- target/arm/Makefile.objs | 1 + 24 files changed, 4164 insertions(+), 834 deletions(-) create mode 100644 target/arm/mte_helper.c -- 2.25.1
