Deadlock event test failure

[bl4ckb0ne]

Hi,

I'm packaging level-zero for AlpineLinux 1 and with the latest release both tests_event_deadlock and tests_event_deadlock_reset are failing on all arches.

Internal ctest changing into directory: /builds/alpine/aports/testing/level-zero/src/level-zero-1.19.2/build

Hi @bl4ckb0ne

In our environment we have not encountered this error. Can you please provide details of the environment where you have encountered the error? Perhaps a docker image for us to reproduce. What GCC are you using, is it 14.2?

How urgent is this for your release? The event_deadlock is an optional feature to validate the usage of event at runtime to find if there is a circular dependency introduced by improper usage of L0 API. In that sense it is not part of the L0 API. We can disable the event_deadlock and you will be able to proceed with your build. In the meantime, we can fix the error for your environment so that you can merge it in your next release. Please let us know.

You can find the official Alpinelinux dockerfiles here, edge is the closest to the setup. We're indeed using GCC 14.2

No hurry on my side, there's no release planed anytime soon, I'm just packaging the release for the distribution. I disabled both tests in the package for the time being.
