[Kernel-packages] [Bug 1954464] Re: kvm SPR support for AMX
Hi Paul, Bugs in launchpad are filed against source packages, and "src:kvm" doesn't exist for more than 8 years now :-) Instead you'd want to file it against the package the code is in, in your case most likely src:qemu [1] or src:linux [2]. Also you should talk about the target Ubuntu release you want the fix to be in. I assume from the type of bug that you want to feature request for the coming LTS Ubuntu 22.04 - but please clarify to be sure. Finally referencing to features/commits works much better if you could please include the hashes of the commits. Please consider doing so once they exist upstream. If they are not existing there someone needs to provide the patches upfront and convince the team that they are stable enough to be picked up. The referred kernel version is in the future, so that might be a normal bug for a new feature. I'll re-assign this to src:linux for now as your bug indicates that is the target.
