tools headers UAPI: Sync linux/kvm.h with the kernel sources

2021-09-10T21:15:22Z

To pick the changes in: f95937ccf5bd5e0a ("KVM: stats: Support linear and logarithmic histogram statistics") f0376edb1ddcab19 ("KVM: arm64: Add ioctl to fetch/store tags in a guest") ea7fc1bb1cd1b92b ("KVM: arm64: Introduce MTE VM feature") That just rebuilds perf, as these patches don't add any new KVM ioctl to be harvested for the the 'perf trace' ioctl syscall argument beautifiers. This is also by now used by tools/testing/selftests/kvm/, so that will pick the new KVM_STATS_TYPE_LINEAR_HIST and KVM_STATS_TYPE_LOG_HIST defines.

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

2021-05-27T11:45:57Z

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

2021-02-10T03:31:08Z

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
