KVM: X86: Use _BITUL() macro in UAPI headers

2021-05-27T11:45:57+00:00

Replace BIT() in KVM's UPAI header with _BITUL(). BIT() is not defined in the UAPI headers and its usage may cause userspace build errors.

KVM/arm64 updates for Linux 5.12 - Make the nVHE EL2 object relocatable, resulting in much more maintainable code - Handle concurrent translation faults hitting the same page in a more elegant way - Support for the standard TRNG hypervisor call - A bunch of small PMU/Debug fixes - Allow the disabling of symbol export from assembly code - Simplification of the early init hypercall handling

KVM: PPC: Book3S HV: Introduce new capability for 2nd DAWR

2021-02-10T03:31:08+00:00

Introduce KVM_CAP_PPC_DAWR1 which can be used by QEMU to query whether KVM supports 2nd DAWR or not. The capability is by default disabled even when the underlying CPU supports 2nd DAWR. QEMU needs to check and enable it manually to use the feature. Signed-off-by: Ravi Bangoria Signed-off-by: Paul Mackerras

tools kvm headers: Update KVM headers from the kernel sources

2020-11-03T11:46:30+00:00

Some should cause changes in tooling, like the one adding LAST_EXCP, but the way it is structured end up not making that happen. The new SVM_EXIT_INVPCID should get used by arch/x86/util/kvm-stat.c, in the svm_exit_reasons table. The tools/perf/trace/beauty part has scripts to catch changes and automagically create tables, like tools/perf/trace/beauty/kvm_ioctl.sh, but changes are needed to make tools/perf/arch/x86/util/kvm-stat.c catch those automatically. These were handled by the existing scripts: $ tools/perf/trace/beauty/kvm_ioctl.sh > before $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h $ tools/perf/trace/beauty/kvm_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:43:52.910728608 -0300 +++ after 2020-11-03 08:44:04.273959984 -0300 @@ -89,6 +89,7 @@ [0xbf] = "SET_NESTED_STATE", [0xc0] = "CLEAR_DIRTY_LOG", [0xc1] = "GET_SUPPORTED_HV_CPUID", + [0xc6] = "X86_SET_MSR_FILTER", [0xe0] = "CREATE_DEVICE", [0xe1] = "SET_DEVICE_ATTR", [0xe2] = "GET_DEVICE_ATTR", $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > before $ cp include/uapi/linux/vhost.h tools/include/uapi/linux/vhost.h $ $ tools/perf/trace/beauty/vhost_virtio_ioctl.sh > after $ diff -u before after --- before 2020-11-03 08:45:55.522225198 -0300 +++ after 2020-11-03 08:46:12.881578666 -0300 @@ -37,4 +37,5 @@ [0x71] = "VDPA_GET_STATUS", [0x73] = "VDPA_GET_CONFIG", [0x76] = "VDPA_GET_VRING_NUM", + [0x78] = "VDPA_GET_IOVA_RANGE", }; $ This addresses these perf build warnings: Warning: Kernel ABI header at 'tools/arch/arm64/include/uapi/asm/kvm.h' differs from latest version at 'arch/arm64/include/uapi/asm/kvm.h' diff -u tools/arch/arm64/include/uapi/asm/kvm.h arch/arm64/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/sie.h' differs from latest version at 'arch/s390/include/uapi/asm/sie.h' diff -u tools/arch/s390/include/uapi/asm/sie.h arch/s390/include/uapi/asm/sie.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/kvm.h' differs from latest version at 'arch/x86/include/uapi/asm/kvm.h' diff -u tools/arch/x86/include/uapi/asm/kvm.h arch/x86/include/uapi/asm/kvm.h Warning: Kernel ABI header at 'tools/arch/x86/include/uapi/asm/svm.h' differs from latest version at 'arch/x86/include/uapi/asm/svm.h' diff -u tools/arch/x86/include/uapi/asm/svm.h arch/x86/include/uapi/asm/svm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h' diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h Warning: Kernel ABI header at 'tools/include/uapi/linux/vhost.h' differs from latest version at 'include/uapi/linux/vhost.h' diff -u tools/include/uapi/linux/vhost.h include/uapi/linux/vhost.h Cc: Adrian Hunter Cc: Alexander Yarygin Cc: Borislav Petkov Cc: Christian Borntraeger Cc: Cornelia Huck Cc: David Ahern Cc: Ian Rogers Cc: Jiri Olsa Cc: Joerg Roedel Cc: Namhyung Kim Signed-off-by: Arnaldo Carvalho de Melo
