Title:
kvm_unit_tests: emulator test fails on 4.15 kernel, timeout
Status in ubuntu-kernel-tests:
In Progress
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Bionic:
In Progress
Bug description:
[Impact]
Our Bionic 4.15 kernel lacks of movups/movupd emulation support.
With the following commit added into the emulator test in
ubuntu_kvm_unit_tests:
8726f9771911d6749dbd36ab2fc70f0f25e2b1a9 is the first bad commit
commit 8726f9771911d6749dbd36ab2fc70f0f25e2b1a9
Author: Jacob Xu <jacob...@google.com>
Date: Wed Apr 21 16:12:57 2021 -0700
x86: add movups/movupd sse testcases to emulator.c
Here we add movups/movupd tests corresponding to functionality
introduced in commit 29916968c486 ("kvm: Add emulation for
movups/movupd").

It will cause the emulator test in ubuntu_kvm_unit_tests fail with timeout:
