FYI I couldn't address all comments from previous iterations, so plan to revisit and self-review some patches, improving commit descriptions. Still good enough for review / testing IMO.
Since v1: - Addressed Mads & Richard comments - Fixed migration by reworking memory listeners (unfortunately the current broken code has been used as base for WHPX) - Sync CNTV_CTL/CVAL_EL0 - Remove WFI racy signal implementation - Simplify PSCI Suspend (I expect the same can be done for the other hvf_psci_cpu_off() calls). - Emulate more missing registers (PMU & Monitor Dbg) >From v1: - Fix a pair of memory leak - Check a pair of return values - Mention calls which must be run on vCPU thread - Force MIDR - Use hv_vcpu_config_create/hv_vcpu_config_get_feature_reg when not running on vCPU thread - Factor hvf_handle_vmexit() / hvf_handle_exception(() out - Call hv_vcpu_run() in loop - Guard hv_vcpu_run() between cpu_exec_start/end() - Restrict ARM specific in AccelCPUState Based-on: <[email protected]> Mohamed Mediouni (2): target/arm/hvf: Hardcode Apple MIDR target/arm/hvf: switch hvf_arm_get_host_cpu_features to not create a vCPU Philippe Mathieu-Daudé (47): target/arm/hvf: Release memory allocated by hv_vcpu_config_create() target/arm/hvf: Trace vCPU KICK events target/arm/hvf: Check hv_vcpus_exit() returned value target/arm/hvf: Check hv_vcpu_set_vtimer_mask() returned value accel/hvf: Rename hvf_vcpu_exec() -> hvf_arch_vcpu_exec() accel/hvf: Rename hvf_put|get_registers -> hvf_arch_put|get_registers target/arm/hvf: Mention flush_cpu_state() must run on vCPU thread accel/hvf: Mention hvf_arch_init_vcpu() must run on vCPU thread target/arm/hvf: Mention hvf_sync_vtimer() must run on vCPU thread target/arm/hvf: Mention hvf_arch_set_traps() must run on vCPU thread accel/hvf: Mention hvf_arch_update_guest_debug() must run on vCPU target/arm/hvf: Mention hvf_inject_interrupts() must run on vCPU thread accel/hvf: Implement hvf_arch_vcpu_destroy() target/arm/hvf: Simplify hvf_arm_get_host_cpu_features() target/arm/hvf: Factor hvf_handle_exception() out target/i386/hvf: Factor hvf_handle_vmexit() out target/arm/hvf: Factor hvf_handle_vmexit() out target/arm/hvf: Keep calling hv_vcpu_run() in loop cpus: Trace cpu_exec_start() and cpu_exec_end() calls accel/hvf: Guard hv_vcpu_run() between cpu_exec_start/end() calls target/arm: Call aarch64_add_pauth_properties() once in host_initfn() accel/hvf: Restrict ARM specific fields of AccelCPUState target/arm: Rename init_cpreg_list() -> arm_init_cpreg_list() target/arm: Better describe PMU depends on TCG or HVF target/arm/hvf: Rename 'vgic' -> 'emu_reginfo' in trace events target/arm/hvf: Emulate PMU registers target/arm/hvf: Emulate Monitor Debug registers target/arm: Re-use arm_is_psci_call() in HVF target/arm: Share ARM_PSCI_CALL trace event between TCG and HVF target/arm/hvf/hvf: Document $pc adjustment in HVF & SMC accel/hvf: Trace prefetch abort accel/hvf: Enforce host alignment when calling hv_vm_protect() accel/hvf: Have WFI returns if !cpu_has_work accel/hvf: Implement WFI without using pselect() accel/hvf: Have PSCI CPU_SUSPEND halt the vCPU accel/hvf: Introduce hvf_arch_cpu_synchronize_[pre/post]exec() hooks target/i386/hvf: Flush vCPU registers once before vcpu_exec() loop target/arm/hvf: Flush vCPU registers once before vcpu_exec() loop accel/hvf: Sync CNTV_CTL_EL0 & CNTV_CVAL_EL0 accel/hvf: Model PhysTimer register accel: Introduce AccelOpsClass::cpu_target_realize() hook accel/hvf: Add hvf_arch_cpu_realize() stubs target/arm: Create GTimers *after* features finalized / accel realized target/arm/hvf: Really set Generic Timer counter frequency accel/hvf: Do not abort in hvf_arm_get_*_ipa_bit_size() hw/arm/virt: Warn when HVF doesn't report IPA bit length target/arm: Only allow disabling NEON when using TCG Richard Henderson (9): accel/hvf: Create hvf_protect_clean_range, hvf_unprotect_dirty_range target/i386/hvf: Use hvf_unprotect_page target/i386/hvf: Use address_space_translate in ept_emulation_fault accel/hvf: Simplify hvf_log_* accel/hvf: Move hvf_log_sync to hvf_log_clear accel/hvf: Simplify hvf_set_phys_mem accel/hvf: Drop hvf_slot and hvf_find_overlap_slot accel/hvf: Remove mac_slots target/arm/hvf: Implement dirty page tracking include/accel/accel-cpu-ops.h | 1 + include/system/hvf_int.h | 49 ++-- target/arm/hvf_arm.h | 11 + target/arm/internals.h | 2 +- accel/accel-common.c | 5 + accel/hvf/hvf-accel-ops.c | 28 +- accel/hvf/hvf-all.c | 184 ++++-------- cpu-common.c | 3 + hw/arm/virt.c | 8 +- target/arm/cpu.c | 71 ++--- target/arm/cpu64.c | 8 +- target/arm/helper.c | 2 +- target/arm/hvf/hvf.c | 494 +++++++++++++++++++------------ target/arm/machine.c | 10 +- target/arm/tcg/psci.c | 3 + target/i386/hvf/hvf.c | 534 ++++++++++++++++++---------------- target/i386/hvf/x86hvf.c | 4 +- accel/hvf/trace-events | 1 + target/arm/hvf/trace-events | 6 +- target/arm/trace-events | 3 + trace-events | 2 + 21 files changed, 759 insertions(+), 670 deletions(-) -- 2.51.0
