This is my current set of patches for running SVE in system mode. The first half deal with the system registers that affect SVE. I recall that Peter has said he'd like the first patch to be done a different way, but we haven't had a chance to talk about what form it should take. I've left it as-is since it does what I need for now.
The second half re-implement the SVE memory operations. The FF and NF loads had been stubbed out. Getting those to work requires some infrastructure that can be reused to speed up normal loads -- one guest-to-host tlb lookup can be reused for the rest of the page. r~ Based-on: <20180809034033.10579-1-richard.hender...@linaro.org> Richard Henderson (20): target/arm: Set ISAR bits for -cpu max target/arm: Set ID_AA64PFR0 bits for SVE for -cpu max target/arm: Define ID_AA64ZFR0_EL1 target/arm: Adjust sve_exception_el target/arm: Fix arm_cpu_data_is_big_endian for aa64 user-only target/arm: Fix arm_current_el for user-only target/arm: Fix is_a64 for user-only target/arm: Pass in current_el to fp and sve_exception_el target/arm: Handle SVE vector length changes in system mode target/arm: Adjust aarch64_cpu_dump_state for system mode SVE target/arm: Clear unused predicate bits for LD1RQ target/arm: Rewrite helper_sve_ld1*_r using pages target/arm: Rewrite helper_sve_ld[234]*_r target/arm: Rewrite helper_sve_st[1234]*_r target/arm: Split contiguous loads for endianness target/arm: Split contiguous stores for endianness target/arm: Rewrite vector gather loads target/arm: Rewrite vector gather stores target/arm: Rewrite vector gather first-fault loads target/arm: Pass TCGMemOpIdx to sve memory helpers target/arm/cpu.h | 47 +- target/arm/helper-sve.h | 385 +++++-- target/arm/internals.h | 5 + target/arm/cpu.c | 24 +- target/arm/cpu64.c | 93 +- target/arm/helper.c | 237 +++-- target/arm/op_helper.c | 1 + target/arm/sve_helper.c | 2062 +++++++++++++++++++++++++----------- target/arm/translate-a64.c | 8 +- target/arm/translate-sve.c | 670 ++++++++---- 10 files changed, 2453 insertions(+), 1079 deletions(-) -- 2.17.1
