  • Describe the issue

At some point between May 22 and May 24, the uring IO support on the ppc64le koji builders seems to have been turned off.

A package I maintain at this time stared failing one of its tests in koschei on ppc64le. The test is testing the software's use of uring IO.

https://koschei.fedoraproject.org/package/root?

The error in the build.log says:

Received unexpected diagnostic of severity 2000 at 'RIoUring' reading 'io_uring is unexpectedly not available because:
Failed to allocate memory for the smallest possible io_uring instance. 'memlock' memory has been exhausted for this user'.

Before no such error was triggered.
Did something change in the setup of the ppc64le koji instances? If so, was this intentional?

We'll investigate, but is there a reason the uring support has to be enabled for builds?

Can you skip the tests that require uring, if no uring is available?

So, I suspect this was because some of the ppc64le builders were reinstalled recently, and when they are reinstalled we have to manually go in and set nested virt on them.

I have gone through them and set it on all of them.

Can you see if that fixes the issue? If it doesn't, can you provide more links to the new failed builds?

I assume this was fixed... and actually we are now on a seperate power10 server.

If you still see problems, please re-open or file a new issue.
