Subject: [PATCH v5 24/37] KVM: selftests: Move HYPERV_LINUX_OS_ID definition to a common header
Date: Fri, 27 May 2022 17:55:33 +0200 [thread overview]
Message-ID: <20220527155546.1528910-25-vkuznets@redhat.com> (raw)
In-Reply-To: <20220527155546.1528910-1-vkuznets@redhat.com>
HYPERV_LINUX_OS_ID needs to be written to HV_X64_MSR_GUEST_OS_ID by
each Hyper-V specific selftest.
