relax-intel-rmrr VS docker-steam-headless

I was in a similar situation as the author: for quite a while I had to build my own Redhat kernel for a very obscure case: by pass RMRR check to pass GPU to a windows VM. (similar to https://github.com/kiler129/relax-intel-rmrr ; not my repo)

The root issue can only be addressed by ROM updates from the manufacturer but I'm running an old DL360 that's no longer supported by HPE.

The patch itself is only one line change but updating the kernel is a pain since I have to :

Good news and bad news, there is a solution: https://github.com/kiler129/relax-intel-rmrr. But it's not always easy unless you understand building kernels. I have to do this on hpe platforms that I own.

One other method I used early in my research was to build a custom kernel that had a patch to ignore the RMRR. That worked really well and everything passed through as it should without issue, but every time you need a kernel upgrade, you have that hassle to deal with. Here is that patch if you'd like to give it a try: https://github.com/kiler129/relax-intel-rmrr

So after some searching I finally found a patch. https://github.com/kiler129/relax-intel-rmrr

So basically, some servers (HP proliant G6, G7 and some more but I don't know them all, i have a g6) have issues with RMRR. In order to fix this, you need to remove the RMRR check. When I used proxmox, I used https://github.com/kiler129/relax-intel-rmrr/blob/master/README.md#proxmox---premade-packages-easy this. Premade packages because I had no clue how to do it myself. That fixed my PCIe passthrough issues. But on manjaro, there is no premade packages for this patch. I have to manually add the patch, compile the kernel and install it and then PCIe passthrough will work hopefully.

I actually just ordered a GPU for my unRaid NAS server just to be able to do Steam Headless via a nice docker image(1) and then use Moonlight (for example) as a client on my Windows laptop. If it works, it's much better than buying yet another piece of desktop hardware just to play games when my NAS is just sitting there idle most of the time. Just need to make sure I keep the power level setting on the Nvidia card to idle when not in use (hopefully a nvidia-persistenced call will do it).

This one??

There's a headless steam docker: https://github.com/Steam-Headless/docker-steam-headless

This will do what you want. Steam Headless.

I'm running Steam Headless and living with the drawbacks. I'd rather figure out how to run games on linux than install Windows, even in a VM. I don't need ads and refuse to give Microsoft any money, anymore.

Or for playing via remote I use this https://github.com/Steam-Headless/docker-steam-headless
