Hi Marc, This is a trivial update to the previously posted v7 [1]. The only changes are a couple of minor cosmetic changes requested by reviewers, on-list and the addition of Acked-by/Reviewed-by tags received since the series was posted. Let me know if you need anything else on this. Cheers ---Dave [1] [PATCH v7 00/16] KVM: arm64: Optimise FPSIMD context switching http://lists.infradead.org/pipermail/linux-arm-kernel/2018-May/576595.html The following changes since commit 6da6c0db5316275015e8cc2959f12a17584aeb64: Linux v4.17-rc3 (2018-04-29 14:17:42 -0700) are available in the git repository at: git://linux-arm.org/linux-dm.git for you to fetch changes up to 90255dd95fe71a9bd1c4ce728abad4b0eec240d9: KVM: arm64: Invoke FPSIMD context switch trap from C (2018-05-16 10:44:00 +0100) ---------------------------------------------------------------- Christoffer Dall (1): KVM: arm/arm64: Introduce kvm_arch_vcpu_run_pid_change Dave Martin (15): thread_info: Add update_thread_flag() helpers arm64: Use update{,_tsk}_thread_flag() KVM: arm64: Convert lazy FPSIMD context switch trap to C arm64: fpsimd: Generalise context saving for non-task contexts arm64/sve: Refactor user SVE trap maintenance for external use KVM: arm64: Repurpose vcpu_arch.debug_flags for general-purpose flags KVM: arm64: Optimise FPSIMD handling to reduce guest/host thrashing arm64/sve: Move read_zcr_features() out of cpufeature.h arm64/sve: Switch sve_pffr() argument from task to thread arm64/sve: Move sve_pffr() to fpsimd.h and make inline KVM: arm64: Save host SVE context as appropriate KVM: arm64: Remove eager host SVE state saving KVM: arm64: Remove redundant *exit_code changes in fpsimd_guest_exit() KVM: arm64: Fold redundant exit code checks out of fixup_guest_exit() KVM: arm64: Invoke FPSIMD context switch trap from C arch/arm/include/asm/kvm_host.h | 9 ++- arch/arm64/Kconfig | 7 ++ arch/arm64/include/asm/cpufeature.h | 29 ------- arch/arm64/include/asm/fpsimd.h | 21 ++++++ arch/arm64/include/asm/kvm_asm.h | 3 - arch/arm64/include/asm/kvm_host.h | 32 +++++--- arch/arm64/include/asm/processor.h | 2 + arch/arm64/kernel/fpsimd.c | 147 +++++++++++++++++++----------------- arch/arm64/kernel/ptrace.c | 1 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/Makefile | 2 +- arch/arm64/kvm/debug.c | 8 +- arch/arm64/kvm/fpsimd.c | 111 +++++++++++++++++++++++++++ arch/arm64/kvm/hyp/debug-sr.c | 6 +- arch/arm64/kvm/hyp/entry.S | 43 ----------- arch/arm64/kvm/hyp/hyp-entry.S | 19 ----- arch/arm64/kvm/hyp/switch.c | 124 ++++++++++++++++++++---------- arch/arm64/kvm/hyp/sysreg-sr.c | 4 +- arch/arm64/kvm/sys_regs.c | 9 +-- include/linux/kvm_host.h | 9 +++ include/linux/sched.h | 6 ++ include/linux/thread_info.h | 11 +++ virt/kvm/Kconfig | 3 + virt/kvm/arm/arm.c | 25 +++++- virt/kvm/kvm_main.c | 7 +- 25 files changed, 406 insertions(+), 233 deletions(-) create mode 100644 arch/arm64/kvm/fpsimd.c _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
