[PATCH v2] selftests/vm: Fix building protection keys test

by Harish

The patch d8cbe8bfa7d tries to include a ARCH check for powerpc, however ARCH is not defined in the Makefile before including lib.mk. This makes test building to skip on both x86 and powerpc. Fix the arch check by replacing it using machine type as it is already defined and used in the test.

[PATCH v2 0/3] RFC: Precise TSC migration

by Maxim Levitsky

Hi! This is the second version of the work to make TSC migration more accurate, as was defined by Paulo at: https://www.spinics.net/lists/kvm/msg225525.html I omitted most of the semi-offtopic points I raised related to TSC in the previous RFC where we can continue the discussion. I do want to raise another thing that I almost forgot. On AMD systems, the Linux kernel will mark the guest tsc as unstable unless invtsc is set which is set on recent AMD hardware. Take a look at 'unsynchronized_tsc()' to verify this. This is another thing that IMHO should be fixed at least when running under KVM. Note that I forgot to mention that X86_FEATURE_TSC_RELIABLE also short-circuits this code, thus giving another reason to enable it under KVM. Changes from V1: - added KVM_TSC_STATE_TIMESTAMP_VALID instead of testing ns == 0 - allow diff < 0, because it is still better that capping it to 0 - updated tsc_msr_test unit test to cover this feature - refactoring Patches to enable this feature in qemu are in the process of being sent to qemu-devel mailing list. Best regards, Maxim Levitsky Maxim Levitsky (3): KVM: x86: implement KVM_{GET|SET}_TSC_STATE KVM: x86: introduce KVM_X86_QUIRK_TSC_HOST_ACCESS kvm/selftests: update tsc_msrs_test to cover KVM_X86_QUIRK_TSC_HOST_ACCESS Documentation/virt/kvm/api.rst | 65 +++++++++++++ arch/x86/include/uapi/asm/kvm.h | 1 + arch/x86/kvm/x86.c | 92 ++++++++++++++++++- include/uapi/linux/kvm.h | 15 +++ .../selftests/kvm/x86_64/tsc_msrs_test.c | 79 ++++++++++++++-- 5 files changed, 237 insertions(+), 15 deletions(-) -- 2.26.2

[PATCHv2] selftests: test_vxlan_under_vrf: mute unnecessary error message

[PATCH v2 1/3] kunit: tool: surface and address more typing issues

by Daniel Latypov

The authors of this tool were more familiar with a different type-checker, https://github.com/google/pytype. That's open source, but mypy seems more prevalent (and runs faster). And unlike pytype, mypy doesn't try to infer types so it doesn't check unanotated functions. So annotate ~all functions in kunit tool to increase type-checking coverage. Note: per https://www.python.org/dev/peps/pep-0484/, `__init__()` should be annotated as `-> None`. Doing so makes mypy discover a number of new violations. Exclude main() since we reuse `request` for the different types of requests, which mypy isn't happy about. This commit fixes all but one error, where `TestSuite.status` might be None.

[PATCH] selftests: propagate CC to selftest submakes

by Andrew Delgadillo

lib.mk defaults to gcc when CC is not set. When building selftests as part of a kernel compilation, MAKEFLAGS is cleared to allow implicit build rules to be used. This has the side-effect of clearing the CC variable, which will cause selftests to be built with gcc regardless of if we are using gcc or clang. To remedy this, propagate the CC variable when clearing makeflags to ensure the correct compiler is used.

[PATCH] selftests: test_vxlan_under_vrf: mute uncessary error message

by Po-Hsu Lin

The cleanup function in this script that tries to delete hv-1 / hv-2 vm-1 / vm-2 netns will generate some uncessary error messages: Cannot remove namespace file "/run/netns/hv-2": No such file or directory Cannot remove namespace file "/run/netns/vm-1": No such file or directory Cannot remove namespace file "/run/netns/vm-2": No such file or directory Redirect it to /dev/null like other commands in the cleanup function to reduce confusion.
