Most notable change is patch 4 from v1, moving up to patch 2 now, to allow the riscv_cpu_cfg() helper to be used in the MISA CSR patch. Changes in v2: - former patch 4 moved to patch 2 - patch 3 (former 2): - use riscv_cpu_cfg() - patch 9: - remove the uneeded RISCVCPUConfig and access mmu via cpu_cfg->cfg.mmu - v1 link: https://lists.gnu.org/archive/html/qemu-devel/2023-02/msg02780.html Daniel Henrique Barboza (11): target/riscv: do not mask unsupported QEMU extensions in write_misa() target/riscv: introduce riscv_cpu_cfg() target/riscv: allow users to actually write the MISA CSR target/riscv: remove RISCV_FEATURE_MISA target/riscv: remove RISCV_FEATURE_DEBUG target/riscv/cpu.c: error out if EPMP is enabled without PMP target/riscv: remove RISCV_FEATURE_EPMP target/riscv: remove RISCV_FEATURE_PMP hw/riscv/virt.c: do not use RISCV_FEATURE_MMU in create_fdt_socket_cpus() target/riscv: remove RISCV_FEATURE_MMU target/riscv/cpu: remove CPUArchState::features and friends hw/riscv/virt.c | 7 ++++--- target/riscv/cpu.c | 20 +++++--------------- target/riscv/cpu.h | 29 ++++++----------------------- target/riscv/cpu_helper.c | 6 +++--- target/riscv/csr.c | 15 ++++++--------- target/riscv/machine.c | 11 ++++------- target/riscv/monitor.c | 2 +- target/riscv/op_helper.c | 2 +- target/riscv/pmp.c | 8 ++++---- 9 files changed, 34 insertions(+), 66 deletions(-) Reviewed-by: Andrew Jones
