About half of this patch set is cleanup of the qemu tlb handling leading up to the actual implementation of VHE, and the biggest piece of that: The EL2&0 translation regime.
Testing so far has been limited to booting a debian 9 system with a 4.9 kernel, and a fedora 30 system with a 5.1 kernel. Both have KVM enabled, and both report enabling VHE is successful. r~ Richard Henderson (24): cputlb: Add tlb_set_asid_for_mmuidx cputlb: Add tlb_flush_asid_by_mmuidx and friends target/arm: Install ASIDs for long-form from EL1 target/arm: Install ASIDs for short-form from EL1 target/arm: Install ASIDs for EL2 target/arm: Define isar_feature_aa64_vh target/arm: Enable HCR_E2H for VHE target/arm: Add CONTEXTIDR_EL2 target/arm: Add TTBR1_EL2 target/arm: Update CNTVCT_EL0 for VHE target/arm: Add the hypervisor virtual counter target/arm: Add VHE system register redirection and aliasing target/arm: Split out vae1_tlbmask, vmalle1_tlbmask target/arm: Simplify tlb_force_broadcast alternatives target/arm: Reorganize ARMMMUIdx target/arm: Add regime_has_2_ranges target/arm: Update arm_mmu_idx for VHE target/arm: Update arm_sctlr for VHE target/arm: Install asids for E2&0 translation regime target/arm: Flush tlbs for E2&0 translation regime target/arm: Update arm_phys_excp_target_el for TGE target/arm: Update regime_is_user for EL2&0 target/arm: Update {fp,sve}_exception_el for VHE target/arm: Enable ARMv8.1-VHE in -cpu max include/exec/cpu-all.h | 11 + include/exec/cpu-defs.h | 2 + include/exec/exec-all.h | 35 ++ include/qom/cpu.h | 1 + target/arm/cpu-qom.h | 1 + target/arm/cpu.h | 259 +++++----- target/arm/internals.h | 62 ++- target/arm/translate.h | 2 +- accel/tcg/cputlb.c | 77 +++ target/arm/arch_dump.c | 2 +- target/arm/cpu.c | 2 + target/arm/cpu64.c | 1 + target/arm/debug_helper.c | 50 +- target/arm/helper-a64.c | 2 +- target/arm/helper.c | 985 ++++++++++++++++++++++++++----------- target/arm/m_helper.c | 6 +- target/arm/pauth_helper.c | 9 +- target/arm/translate-a64.c | 14 +- target/arm/translate.c | 17 +- 19 files changed, 1058 insertions(+), 480 deletions(-) -- 2.17.1
