It allows the hypervisor to deliver NMI-alike event to guest and it's needed by asynchronous page fault to deliver page-not-present notification from hypervisor to guest. The code and the required qemu changes can be found from: https://developer.arm.com/documentation/den0054/latest https://github.com/gwshan/linux ("kvm/arm64_sdei") https://github.com/gwshan/qemu ("kvm/arm64_sdei") The SDEI event is identified by a 32-bits number. Bits[31:24] are used to indicate the SDEI event properties while bits[23:0] are identifying the unique number. The implementation takes bits[23:22] to indicate the owner of the SDEI event. For example, those SDEI events owned by KVM should have these two bits set to 0b01. Besides, the implementation supports SDEI events owned by KVM only. The design is pretty straightforward and the implementation is just following the SDEI specification, to support the defined SMCCC intefaces, except the IRQ binding stuff. There are several data structures introduced. Some of the objects have to be migrated by VMM. So their definitions are split up for VMM to include the corresponding states for migration. struct kvm_sdei_kvm Associated with VM and used to track the KVM exposed SDEI events and those registered by guest. struct kvm_sdei_vcpu Associated with vCPU and used to track SDEI event delivery. The preempted context is saved prior to the delivery and restored after that. struct kvm_sdei_event SDEI events exposed by KVM so that guest can register and enable. struct kvm_sdei_kvm_event SDEI events that have been registered by guest. struct kvm_sdei_vcpu_event SDEI events that have been queued to specific vCPU for delivery. The series is organized as below: PATCH[01] Introduces template for smccc_get_argx() PATCH[02] Introduces the data structures and infrastructure PATCH[03-14] Supports various SDEI related hypercalls PATCH[15] Supports SDEI event notification PATCH[16-17] Introduces ioctl command for migration PATCH[18-19] Supports SDEI event injection and cancellation PATCH[20] Exports SDEI capability PATCH[21] Adds self-test case for SDEI virtualization Testing ======= There are additional patches in the following repositories to create procfs entries, allowing inject SDEI event and test driver in the guest to handle the SDEI event. Besides, the additional QEMU changes are needed so that guest can detect the SDEI service through ACPI table. https://github.com/gwshan/linux ("kvm/arm64_sdei") https://github.com/gwshan/qemu ("kvm/arm64_sdei") The SDEI event is received and handled in the guest after it's injected through the procfs entries from host side. host# /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \ -accel kvm -machine virt,gic-version=host \ -cpu host -smp 8,sockets=2,cores=4,threads=1 -m 1024M \ : \ -kernel /home/gavin/sandbox/linux.guest/arch/arm64/boot/Image \ -initrd /home/gavin/sandbox/images/rootfs.cpio.xz \ -append 'earlycon=pl011,mmio,0x9000000' host# echo > /proc/kvm/kvm-10842/vcpu-0 guest# =========== SDEI Event (CPU#0) =========== num=0x40400000, arg=0xdabfdabf SP: 0xffff800011613e90 PC: 0x0 pState: 0x0 Regs: 000000000002ac4 ffff00001ff947a0 0000000000002ac2 ffff00001ff976c0 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 ffff80001121a000 ffff8000116199e0 ffff800011619ad8 ffff80001122d8b8 ffff800011619afc 0000000000000000 0000000000000000 ffff800011622140 ffff800011150108 00000000582c0018 ffff800011613e90 ffff800010bd0248 Query context: x[00]: 0000000000002ac4 errno: 0 x[01]: ffff00001ff947a0 errno: 0 : x[18]: ffff800010bd01d8 errno: 0 x[19]: fffffffffffffffe errno: -22 x[20]: fffffffffffffffe errno: -22 : x[30]: fffffffffffffffe errno: -22 host# echo > /proc/kvm/kvm-10842/vcpu-7 guest# =========== SDEI Event (CPU#7) =========== num=0x40400000, arg=0xdabfdabf SP: 0xffff800011b73f20 PC: 0x0 pState: 0x0 Regs: 00000000000010d0 ffff00003fde07a0 00000000000010ce 7fffffff1999999a 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 0000000000000000 ffff80001121a000 ffff8000116199e0 ffff800011619ad8 ffff80001122d8b8 ffff800011619afc 0000000000000000 0000000000000000 ffff000020032ac0 0000000000000000 0000000000000000 ffff800011b73f20 ffff800010bd0248 Query context: x[00]: 00000000000010d0 errno: 0 x[01]: ffff00003fde07a0 errno: 0 : x[18]: ffff800010bd01d8 errno: 0 x[19]: fffffffffffffffe errno: -22 : x[30]: fffffffffffffffe errno: -22 Changelog ========= v4: * Rebased to v5.14.rc5 (Gavin) v3: * Rebased to v5.13.rc1 (Gavin) * Use linux data types in kvm_sdei.h (Gavin) v2: * Rebased to v5.11.rc6 (Gavin) * Dropped changes related to SDEI client driver (Gavin) * Removed support for passthrou SDEI events (Gavin) * Redesigned data structures (Gavin) * Implementation is almost rewritten as the data structures are totally changed (Gavin) * Added ioctl commands to support migration (Gavin) Gavin Shan (21): KVM: arm64: Introduce template for inline functions KVM: arm64: Add SDEI virtualization infrastructure KVM: arm64: Support SDEI_VERSION hypercall KVM: arm64: Support SDEI_EVENT_REGISTER hypercall KVM: arm64: Support SDEI_EVENT_{ENABLE, DISABLE} hypercall KVM: arm64: Support SDEI_EVENT_CONTEXT hypercall KVM: arm64: Support SDEI_EVENT_UNREGISTER hypercall KVM: arm64: Support SDEI_EVENT_STATUS hypercall KVM: arm64: Support SDEI_EVENT_GET_INFO hypercall KVM: arm64: Support SDEI_EVENT_ROUTING_SET hypercall KVM: arm64: Support SDEI_PE_{MASK, UNMASK} hypercall KVM: arm64: Support SDEI_{PRIVATE, SHARED}_RESET hypercall KVM: arm64: Impment SDEI event delivery KVM: arm64: Support SDEI_EVENT_{COMPLETE, COMPLETE_AND_RESUME} hypercall KVM: arm64: Support SDEI event notifier KVM: arm64: Support SDEI ioctl commands on VM KVM: arm64: Support SDEI ioctl commands on vCPU KVM: arm64: Support SDEI event injection KVM: arm64: Support SDEI event cancellation KVM: arm64: Export SDEI capability KVM: selftests: Add SDEI test case arch/arm64/include/asm/kvm_emulate.h | 1 + arch/arm64/include/asm/kvm_host.h | 8 + arch/arm64/include/asm/kvm_sdei.h | 136 ++ arch/arm64/include/uapi/asm/kvm.h | 1 + arch/arm64/include/uapi/asm/kvm_sdei.h | 86 ++ arch/arm64/kvm/Makefile | 2 +- arch/arm64/kvm/arm.c | 19 + arch/arm64/kvm/hyp/exception.c | 7 + arch/arm64/kvm/hypercalls.c | 18 + arch/arm64/kvm/inject_fault.c | 27 + arch/arm64/kvm/sdei.c | 1519 ++++++++++++++++++++ include/kvm/arm_hypercalls.h | 34 +- include/uapi/linux/kvm.h | 4 + tools/testing/selftests/kvm/Makefile | 1 + tools/testing/selftests/kvm/aarch64/sdei.c | 171 +++ 15 files changed, 2014 insertions(+), 20 deletions(-) create mode 100644 arch/arm64/include/asm/kvm_sdei.h create mode 100644 arch/arm64/include/uapi/asm/kvm_sdei.h create mode 100644 arch/arm64/kvm/sdei.c create mode 100644 tools/testing/selftests/kvm/aarch64/sdei.c -- 2.23.0
