[PATCH 0/4] kvm: arm64: emulate ID registers
by Yang Yingliang 25 Aug '20

25 Aug '20

In AArch64, guest will read the same values of the ID regsiters with host. Both of them read the values from arm64_ftr_regs. This patch series add support to emulate and configure ID registers so that we can control the value of ID registers that guest read. Peng Liang (4): arm64: add a helper function to traverse arm64_ftr_regs kvm: arm64: emulate the ID registers kvm: arm64: make ID registers configurable kvm: arm64: add KVM_CAP_ARM_CPU_FEATURE extension arch/arm64/include/asm/cpufeature.h | 2 + arch/arm64/include/asm/kvm_host.h | 2 + arch/arm64/kernel/cpufeature.c | 13 ++++++ arch/arm64/kvm/sys_regs.c | 71 ++++++++++++++++++++++------- include/uapi/linux/kvm.h | 13 ++++++ virt/kvm/arm/arm.c | 23 ++++++++++ 6 files changed, 107 insertions(+), 17 deletions(-) -- 2.25.1

[PATCH 01/22] arm64: mm: define NET_IP_ALIGN to 0
by Yang Yingliang 25 Aug '20

25 Aug '20

From: Ard Biesheuvel <ard.biesheuvel(a)linaro.org> mainline inclusion from mainline-v4.20-rc2 commit 26a4676faa1ad5d99317e0cd701e5d6f3e716b77 category: feature bugzilla: NA CVE: NA --------------------------- On arm64, there is no need to add 2 bytes of padding to the start of each network buffer just to make the IP header appear 32-bit aligned. Since this might actually adversely affect DMA performance some platforms, let's override NET_IP_ALIGN to 0 to get rid of this padding.

We do not have a plan to support ARM32 at this point, and it would be great if you could help to do it. IMHO, the patches merged into the openEuler kernel do not break the support for ARM32. So, select a proper config would be helpful for building on arm32 platform. > > Looking for your rely. > > _______________________________________________ > Dev mailing list -- dev(a)openeuler.org > To unsubscribe send an email to dev-leave(a)openeuler.org >

20 Aug '20

This patch set aims to support the vCPU preempted check and PV qspinlock under KVM/arm64. Christoffer Dall (1): KVM: arm/arm64: Factor out hypercall handling from PSCI code Qian Cai (1): arm64/spinlock: fix a -Wunused-function warning Steven Price (3): KVM: Implement kvm_put_guest() arm/arm64: Provide a wrapper for SMCCC 1.1 calls arm/arm64: Make use of the SMCCC 1.1 wrapper Waiman Long (1): locking/osq: Use optimized spinning loop for arm64 Wanpeng Li (2): KVM: Boost vCPUs that are delivering interrupts KVM: Check preempted_in_kernel for involuntary preemption Zengruan Ye (12): arm/paravirt: Use a single ops structure KVM: arm64: Document PV-sched interface KVM: arm64: Implement PV_SCHED_FEATURES call KVM: arm64: Support pvsched preempted via shared structure KVM: arm64: Add interface to support vCPU preempted check KVM: arm64: Support the vCPU preemption check KVM: arm64: Add SMCCC PV-sched to kick cpu KVM: arm64: Implement PV_SCHED_KICK_CPU call KVM: arm64: Add interface to support PV qspinlock KVM: arm64: Enable PV qspinlock KVM: arm64: Add tracepoints for PV qspinlock arm64: defconfig: add CONFIG_PARAVIRT_SPINLOCKS in default Documentation/virtual/kvm/arm/pvsched.txt | 72 ++++++++ arch/arm/include/asm/kvm_host.h | 25 +++ arch/arm/include/asm/paravirt.h | 9 +- arch/arm/kernel/paravirt.c | 4 +- arch/arm/kvm/Makefile | 2 +- arch/arm/kvm/handle_exit.c | 2 +- arch/arm/mm/proc-v7-bugs.c | 13 +- arch/arm64/Kconfig | 14 ++ arch/arm64/configs/euleros_defconfig | 1 + arch/arm64/configs/hulk_defconfig | 1 + arch/arm64/configs/openeuler_defconfig | 1 + arch/arm64/include/asm/kvm_host.h | 20 +++ arch/arm64/include/asm/paravirt.h | 63 ++++++- arch/arm64/include/asm/pvsched-abi.h | 16 ++ arch/arm64/include/asm/qspinlock.h | 15 +- arch/arm64/include/asm/qspinlock_paravirt.h | 12 ++ arch/arm64/include/asm/spinlock.h | 26 +++ arch/arm64/kernel/Makefile | 3 +- arch/arm64/kernel/alternative.c | 5 +- arch/arm64/kernel/cpu_errata.c | 82 +++------ arch/arm64/kernel/paravirt-spinlocks.c | 18 ++ arch/arm64/kernel/paravirt.c | 188 +++++++++++++++++++- arch/arm64/kernel/setup.c | 2 + arch/arm64/kernel/trace-paravirt.h | 66 +++++++ arch/arm64/kvm/Makefile | 2 + arch/arm64/kvm/handle_exit.c | 5 +- arch/s390/kvm/interrupt.c | 2 +- drivers/xen/time.c | 4 + include/kvm/arm_hypercalls.h | 43 +++++ include/kvm/arm_psci.h | 2 +- include/linux/arm-smccc.h | 71 ++++++++ include/linux/cpuhotplug.h | 1 + include/linux/kvm_host.h | 23 +++ include/linux/kvm_types.h | 2 + kernel/locking/osq_lock.c | 23 ++- virt/kvm/arm/arm.c | 12 +- virt/kvm/arm/hypercalls.c | 72 ++++++++ virt/kvm/arm/psci.c | 76 +------- virt/kvm/arm/pvsched.c | 83 +++++++++ virt/kvm/arm/trace.h | 18 ++ virt/kvm/kvm_main.c | 17 +- 41 files changed, 939 insertions(+), 177 deletions(-) create mode 100644 Documentation/virtual/kvm/arm/pvsched.txt create mode 100644 arch/arm64/include/asm/pvsched-abi.h create mode 100644 arch/arm64/include/asm/qspinlock_paravirt.h create mode 100644 arch/arm64/kernel/paravirt-spinlocks.c create mode 100644 arch/arm64/kernel/trace-paravirt.h create mode 100644 include/kvm/arm_hypercalls.h create mode 100644 virt/kvm/arm/hypercalls.c create mode 100644 virt/kvm/arm/pvsched.c -- 2.25.1
