Subject: [PATCH 1/3] KVM: selftests: Test MONITOR and MWAIT, not just MONITOR for quirk
Date: Mon, 11 Jul 2022 22:57:51 +0000 [thread overview]
Message-ID: <20220711225753.1073989-2-seanjc@google.com> (raw)
In-Reply-To: <20220711225753.1073989-1-seanjc@google.com>
Fix a copy+paste error in monitor_mwait_test by switching one of the two
"monitor" instructions to an "mwait". The intent of the test is very
much to verify the quirk handles both MONITOR and MWAIT.
Fixes: 2325d4dd7321 ("KVM: selftests: Add MONITOR/MWAIT quirk test")
Reported-by: Yuan Yao <yuan.yao@linux.intel.com>
