Subject: [PATCH 0/4] kvm: cpuid: fix cpuid nent field
Date: Tue, 30 Mar 2021 20:58:37 +0200 [thread overview]
Message-ID: <20210330185841.44792-1-eesposit@redhat.com> (raw)
This series aims to clarify the behavior of
KVM_GET_EMULATED_CPUID and KVM_GET_SUPPORTED
ioctls, and fix a corner case where the nent field of the
struct kvm_cpuid2 is matching the amount of entries that kvm returns.
Patch 1 proposes the nent field fix to cpuid.c,
patch 2 updates the ioctl documentation accordingly and
patches 3 and 4 provide a selftest to check KVM_GET_EMULATED_CPUID
accordingly.
Emanuele Giuseppe Esposito (4):
kvm: cpuid: adjust the returned nent field of kvm_cpuid2 for
KVM_GET_SUPPORTED_CPUID and KVM_GET_EMULATED_CPUID
