2021-02-19tests/qtest/boot-sector: Check that the guest did not panicThomas Huth1-0/+9
The s390-ccw bios code panics if it can not boot successfully. In this case, it does not make sense that we wait the full 600 seconds for the boot sector test to finish and can signal the failure immediately, thus let's check the status of the guest with the "query-status" QMP command here, too.

2021-02-19scripts/checkpatch: Improve the check for authors mangled by the mailing listThomas Huth1-1/+1
There were recently some patches on the list which had their "From:" line mangled like this: From: qemu_oss--- via <qemu-devel@nongnu.org> Since our test in the checkpatch.pl script did not trigger here, the patches finally also ended up in a pull request, with the wrong author set. So let's improve the regular expression to also complain on these new patterns, too.

Since commit ba2232bae6d ("gitlab-ci: Refactor code that show logs of failed acceptances") we display the log content of failing tests (Avocado "FAIL" event). Since we are also interested in tests timeouting, update our global Avocado config to display log content for the "INTERRUPT" event, "possible when the timeout is reached" (See [*]).

2021-02-19gitlab: always build container imagesDaniel P. Berrangé1-7/+0
Currently we attempt to skip building container images if the commits do not involve changes to the dockerfiles or gitlab CI definitions. Conceptually this makes sense, but there is a challenge in the real world implementation of this in gitlab. In the case of a CI pipeline triggered from a merge request, GitLab knows the common ancestor of the merge request and the main git repo, so it can trivially determine if any of the commits associated with the MR change the dockerfiles. In the case of a CI pipeline triggered from a push to a branch, it is much more difficult. There is no concept of a common ancestor in this case. Instead GitLab looks at the set of commits in the git push event. On the surface this may sound reasonable, but it doesn't take into account that a push event does not always contain the full set of patches from a branch. For example, consider pushing 5 commits, one of which contains a dockerfile change. This will trigger a CI pipeline for the containers. Now consider you do some more work on the branch and push 3 further commits, so you now have a branch of 8 commits. For the second push GitLab will only look at the 3 most recent commits, the other 5 were already present. Thus GitLab will not realize that the branch has dockerfile changes that need to trigger the container build. This can cause real world problems: - Push 5 commits to branch "foo", including a dockerfile change => rebuilds the container images with content from "foo" => build jobs runs against containers from "foo" - Refresh your master branch with latest upstream master => rebuilds the container images with content from "master" => build jobs runs against containers from "master" - Push 3 more commits to branch "foo", with no dockerfile change => no container rebuild triggers => build jobs runs against containers from "master" The "changes" conditional in gitlab is OK, *provided* your build jobs are not relying on any external state from previous builds. This is NOT the case in QEMU, because we are building container images and these are cached. This is a scenario in which the "changes" conditional is not usuable. The only other way to avoid this problem would be to use the git branch name as the container image tag, instead of always using "latest". The downside of this approach is that the user's gitlab registry will grow significantly until it starts to trigger GitLab's automatic deletion policy. Every time the user starts a new branch they will have to trigger a rebuild of the container images. Given this, we might as well just drop the conditional and always build the container images. Most of the time docker will be able to use the layer cache to avoid the most expensive part of the rebuild process (installing all the RPMs/debs/etc) Signed-off-by: Daniel P.

2021-02-19tests/qtest/boot-serial-test: Test Virt machine with 'max'Philippe Mathieu-Daudé1-1/+1
When using KVM, using a specific cpu type will only work if the host CPU really is that exact CPU type. During testing we can simply use the 'max' CPU which will select all the features available from the host. This allow running this test on a Cavium CN8890 (ThunderX cores).

2021-02-18accel/tcg: allow plugin instrumentation to be disable via cflagsAlex Bennée7-27/+49
When icount is enabled and we recompile an MMIO access we end up double counting the instruction execution. To avoid this we introduce the CF_MEMI cflag which only allows memory instrumentation for the next TB (which won't yet have been counted). As this is part of the hashed compile flags we will only execute the generated TB while coming out of a cpu_io_recompile. While we are at it delete the old TODO. We might as well keep the translation handy as it's likely you will repeatedly hit it on each MMIO access.
