[PATCH] selftests/tracing: Test only toplevel README file not the instances

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> For the tests that have both a README attribute as well as the instance flag to run the tests as an instance, the instance version will always exit with UNSUPPORTED. That's because the instance directory does not contain a README file. Currently, the tests check for a README file in the directory that the test runs in and if there's a requirement for something to be present in the README file, it will not find it, as the instance directory doesn't have it. Have the tests check if the current directory is an instance directory, and if it is, check two directories above the current directory for the README file: /sys/kernel/tracing/README /sys/kernel/tracing/instances/foo/../../README Signed-off-by: Steven Rostedt (Google) <rostedt(a)goodmis.org> --- tools/testing/selftests/ftrace/test.d/functions | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/tools/testing/selftests/ftrace/test.d/functions b/tools/testing/selftests/ftrace/test.d/functions index 779f3e62ec90..9f2a67fbaf4d 100644 --- a/tools/testing/selftests/ftrace/test.d/functions +++ b/tools/testing/selftests/ftrace/test.d/functions @@ -156,7 +156,13 @@ check_requires() { # Check required files and tracers exit_unsupported fi elif [ "$r" != "$i" ]; then - if ! grep -Fq "$r" README ; then + # If this is an instance, check the top directory + if echo $TRACING_DIR | grep -q "/instances/"; then + test="$TRACING_DIR/../.." + else + test=$TRACING_DIR + fi + if ! grep -Fq "$r" $test/README ; then echo "Required feature pattern \"$r\" is not in README." exit_unsupported fi -- 2.45.2

"stty sane" in kunit.py

by Brendan Jackman

Hi all, Does anyone know what the 'stty sane' invocation in kunit.py is about? The other day I ran into an issue when running it via watchexec[1]. At the time I believed that it was there to clean up after the firmware that QEMU runs potentially messed up the terminal. However, I just realised I'm not sure if that makes sense - stty is about setting terminal settings via ioctl. I don't think QEMU or its guests are messing up the terminal with ioctls, they're just writing funny control characters. What's going on here? I guess one of: 1. Terminal is messed up with ctrl chars but ioctls are the easiest/only way to reliably clean it up. 2. Nobody thought about this unimportant detail so hard before and there's no particular rationale in place here. 3. I made bad assumptions about why the `stty sane` is there. If it's 1 or 2 I wonder if there's an alternative way to clean up without getting the SIGTTOU issue. Or, maybe it doesn't matter and the fact that this was ever a problem is just a bug in watchexec (maybe you can tell I haven't actually taken the time to research the SIGTTOU thing properly). But thought I'd raise it in case this points to issues people might have using kunit.py in CI. [1] https://github.com/watchexec/watchexec/issues/874 [2] https://gist.github.com/bjackman/27fd9980d87c5556c20e67a6ed891500

[PATCH v5 00/14] iommufd: Add vIOMMU infrastructure (Part-3: vEVENTQ)

by Nicolin Chen

As the vIOMMU infrastructure series part-3, this introduces a new vEVENTQ object. The existing FAULT object provides a nice notification pathway to the user space with a queue already, so let vEVENTQ reuse that. Mimicing the HWPT structure, add a common EVENTQ structure to support its derivatives: IOMMUFD_OBJ_FAULT (existing) and IOMMUFD_OBJ_VEVENTQ (new). An IOMMUFD_CMD_VEVENTQ_ALLOC is introduced to allocate vEVENTQ object for vIOMMUs. One vIOMMU can have multiple vEVENTQs in different types but can not support multiple vEVENTQs in the same type. The forwarding part is fairly simple but might need to replace a physical device ID with a virtual device ID in a driver-level event data structure. So, this also adds some helpers for drivers to use. As usual, this series comes with the selftest coverage for this new ioctl and with a real world use case in the ARM SMMUv3 driver.
