[Feature] rpm kmod build support #1002

Closed Hero9909 closed 2 years ago

Hero9909 commented 2 years ago

Usecase

use kvmfr in fedora silverblue as dkms isn't currently possible #1091 (minor) easier install on rpm based systems

Possible Solutions

provide a kvmfr.spec for manual rpm-build or further automatic build via copr

Required work

for a manual build, as mentioned above, the kvmfr.spec is required. this provides basic instructions on what files are needed for this kernel module and which have to be installed.

For an automatic build, which of course has to be maintained by someone, an srpm is required. This could be also generated by a GitHub action.

What I have done or what I could already provide

I have already done a manual rpm build, but I'm not sure if everything is done well enough to be used in production. I can provide a kvmfr.spec, if desired. I already got a build up and running for some frames, but the bleeding edge contains an error about Nvidia's DMA update, which didn't happen before.

ill test around with an build from the B5 - release version and give an update in the comments

After some testing, I thought I got the difference that should be the issue: my secondary VM is a QXL-powered one. But I've tested this behavior with another configuration, I've passed my secondary GPU (gtx950) to this VM, and it's the same issues again. so this is definitely an issue of the Linux build as my connection to the windows VM remains stable. even though I managed to pass a few frames around, this connection didn't last long.

Currently, I can't disguise if it's a fault in my build / configuration / setup or a deeper error.

For information, my current setup consists of my host - AMD 1950X - GTX 970 - GTX 950 and my configuration for my VMS Private - GTX 970 Secondary - GTX 950 or GTX 970 or QXL Windows - GTX 950 If I can help anyone by testing around with a special setup & looking-glass, just ask, ill try.

Anyway, for a general decision, these issues should not matter and should be resolved in a different thread.

This project doesn't target a specific distribution, if you need additional things such as this either provide them yourself or wait for packaging by your distro maintainers.
