mikedpitt420 Posted June 25, 2015 Share Posted June 25, 2015 That pretty much sums up my question. I have the equipment below in my sig. and the CPU is an A10 with a Radeon HD 7660D onboard. It is the only display, but the server is headless. I'm sure this is probably a silly question, but wouldn't it just be possible to get into the BIOS etc. if I needed to via a serial connection? Passing the primary GPU to this KVM? I just have little to no experience with this at all, so apologies if this is an entirely misguided or dumb question. Would I be better off trying to passthrough a small PCI card of some type? I haven't really noticed the need for it yet, as this is only an instance of Mythbuntu 12.04 running as a backend only and tuning 2x HDHR Prime's. I wasn't sure if I really started to push this thing and tune a bunch of channels at once, if it would even benefit me in any way to try to passthrough a GPU or just continue emulating one as I have been. Any direction would be greatly appreciated. EDIT: I see in the manual this is not supported. Is this planned for in the future? Link to comment

There is a project in the works called KVMgt which sounds promising, but is not available yet. That said, even if it does become available, there's a good chance it will require new hardware (not guaranteed to, but if I was betting man, I would wager so). There is a long list of reasons why integrated graphics aren't supported, but the short reason is that they do not conform to the standards of discrete PCI-based graphics (add-on cards) or frankly, the standards of any other type of PCI device. The uniqueness of integrated graphics from chipset to chipset combined with other factors are the primary issues at play. And of course, there is the economical reason this isn't a priority: getting a add-on GPU isn't expensive, and many low-end cards are fanless. Longer term, I am hopeful that we will see a day where all PCI devices are assignable, regardless of type, but that day may still be a bit down the road just yet... Link to comment
mikedpitt420 Posted June 25, 2015 Author Share Posted June 25, 2015 I'll do some research on a discrete fanless GPU. Thanks a ton! Link to comment
mikedpitt420 Posted June 26, 2015 Author Share Posted June 26, 2015 When I click on the Info button on the unRAID UI main screen, my system reports that it has HVM and IOMMU enabled. Does this mean I am able to pass though a PCI discrete GPU then? I haven't been able to find any definitive answer anywhere If it is indeed a yes, what would be a good small preferably fanless PCI GPU that is most likely to work without issue? This is for a Gigabyte F2A88X-D3H motherboard. Link to comment
jonp Posted June 27, 2015 Share Posted June 27, 2015 Yes, if both are enabled then yes, it Should Work. The documentation is in the wiki. It's linked from the support menu on our website as well. As far as a GPU recommendation, what are you looking to do with this GPU and for what VMs (windows, Linux, etc)? Link to comment
mikedpitt420 Posted June 27, 2015 Author Share Posted June 27, 2015 I'm looking to run a VM instance of Mythtbuntu to tune 2 HDHomerun Primes. Link to comment
jonp Posted June 27, 2015 Share Posted June 27, 2015 Hmm, I've not actually set that up myself, but bet some others have. Generally speaking, nvidia cards have been easier to work with, but that's not to say that AMD devices don't work. We have a 5450 and 6450 AMD that we've had success with passing through, but like I said, NVIDIA is my preference for this right now. Link to comment
mikedpitt420 Posted June 27, 2015 Author Share Posted June 27, 2015 There isn't any place that I'd be able to confirm that a certain GPU would passthrough my Mobo anywhere before I order? My mobo reports IOMMU is enabled, nowhere to check that? Link to comment
jonp Posted June 27, 2015 Share Posted June 27, 2015 See the wiki in my signature. There is a spreadsheet on GPU pass through combos that have worked that is maintained outside of this community. The link is in the wiki. Link to comment

I see the model in the Graphics Card: drop down menu. Link to comment
