XCP-NG 9.0 Support for GRAID Tech GPU-accelerated RAID cards.

[hydromike]

I have started a conversation with them about getting support for XCP-NG, for the VROC and the Supreme RAID solutions. I am looking at this as a forward looking effort. In these efforts I have found that Alma 10 is roughly what 9.0 is based upon. What do I need to get pulled together to make this happen. I actually am having a call with there DEV team today. To pull what is on there end that needs rot make it work. I will update this with what happens on the call today. I use there GPU-cards in 4 nodes that an are separate, each is part of GPU cluster. I have wanted to build out the next customers clusters with XCP-NG with the accelerators in them.

Thanks for chasing this with them, and for offering to post back after the call.

Your Alma 10 read looks right (the 9.0 demonstrator is Xen 4.19 with a dom0 loosely based on AlmaLinux 10 and a 6.12 kernel), but @yann said in July they're out of prototyping and rebuilding the foundations component by component, so I wouldn't treat that kernel as the one their driver ends up targeting.
On the packaging side, the kernel module policy page is the nearest thing I've found to an answer for what you'd need to pull together: https://docs.xcp-ng.org/project/development-process/kernel-module-policy

For VROC, my understanding is that it sits on VMD, though I could have that backwards. VMD stalled boot on the demonstrator kernel back in January until yann said he'd include a patch for it, so that stretch of the thread is worth a read before your call: https://xcp-ng.org/forum/topic/11698

I don't know enough about driver packaging to say what Vates would actually need from GRAID, so it might be worth pulling in @Team-Hypervisor-Kernel, since drivers are their scope.
If the call gives you a list of what they need from our side, that's probably the most useful thing to bring back here.
