Well the 780 comes with a DVI -> VGA adapter in the box.  (and a CD-R of the at then drivers and nothing else. You bought a GPU and that's all you get these days unless there is some Nvidia Game Promo going on).

Saw there was a new XPS 13 with that on the top i7 Model. Looks like a good chip for an IGP.

Matter of fact, I was bouncing the card between guest and host as needed without rebooting. It's just, I spent too much time in the VM to make this whole shebang worthwhile to begin with. Might as well run Windows natively. So any resources for us or do you just need a high end virtual ready processor and mobo? You are one of like 4 people online I have found messing with this... To my shame I suck at grub, I think I need to use lilo to dual boot, other than that I seem pretty tech savy.

Other than that, Linux kernel 4.4 or 4.5, QEMU 2.5 and a willingness to skip libvirt. IMO the more direct control of the QEMU command line is of advantage for maximizing guest performance. I can repost my current version of the QEMU script as reference when I'm back from work. Combat Pretzel fucked around with this message at 08:44 on Mar 15, 2016 |

Combat Pretzel posted:Eh, I had a Pastebin link in my history. Thanks a lot for posting this! I just got qemu setup to run a Windows 10 VM for games with GPU pass-through. It works pretty well thus far, but passing the GPU back and forth between the host and VM would be pretty amazing. Given that I've already setup everything for Vt-d and GPU pass-through, is there any other preparation needed to swap the GPU back and forth between the host and VM besides your script? Would you mind elaborating on your script some? For instance, does this mean you are able to run the pass-through GPU on your host's X session, take it down dynamically, and then reattach it to the X session when you're done? I notice in the script it says not to run it under X. You use Q35 as the emulated chipset, but most guides I see leave it on the 440fx chipset. It looks like you've got a lot of hyper-v stuff enabled, is that something you can re-enable after you get the nvidia driver installed? Or are you using AMD GPUs? Please tell me more

The X shutdown stuff was done in another script using systemd-run, so it'd survive a change in systemd isolate. It'd change from graphical to multi-user to kill the X session, wait for xinit to go away and then run the script I linked with Pastebin. After QEMU stops blocking the execution of the scripts, it'd change back from multi-user to graphical, which would restart X. I'd upload it, but I forgot to copy it when I reinstalled Windows. Be aware that the X session gets killed dead, and as such all apps running in it. And I was swapping the secondary controller. The primary kept running the framebuffer console. Some dude on reddit I pm'd with tried to get the primary working, seemed to have some intermittent success in releasing all drivers from it, but then I never heard again from him. Regarding 440fx, I couldn't get a decent answer for this, because the documentation is pretty non-specific and seems out of date in places (calling Q35 relatively new and unstable, despite being there for years now, plus it's being actively maintained in the git, unlike 440fx). Q35 defines the newer ICH9 chipset, which has a proper PCIe bus hierarchy, all chipset devices support MSI interrupts (less overhead) and the OVMF UEFI stuff works better with it (for me, anyway). As far as Hyper-V goes, the NVidia drivers look for the Hyper-V CPUID and refuse to start when they see it. QEMU 2.5 allows to specify a custom one for obfuscation via hv-vendor-id on the -cpu line (that's why it's there), which lets you use the NVidia driver without issues. For now, anyway, because months ago, the NVidia driver apparently didn't care about the Hyper-V CPUID to begin with. Chances are a newer version will look for other signs to identify Hyper-V eventually and then stop working again. Either way, enabling Hyper-V improves framerates a lot. If your CPU is older than a Haswell or Ivy Bridge-E, you should also specify hvapic for the Hyper-V virtual APIC. Do not specify it with these or newer CPUs, because they support hardware virtualization of the APIC, which has less hypervisor overhead. Also, check whether MSI interrupts got enabled for graphics, the HD audio device and the USB controllers, to eke out some more performance. MSI interrupts have less hypervisor overhead, too. Specifics here: http://vfio.blogspot.be/2014/09/vfio-interrupts-and-how-to-coax-windows.html Personally, I'm holding off a while of this VM stuff, hoping that NVidia will release their Wayland support finally. Pissed me off that I couldn't get a 60fps compositing desktop working with neither mutter or compton (pissed me off seeing the smooth compositing every time I booted into the VM). Load Chrome and your framerate's hosed. Worked fine with Gnome Wayland, but that required the nouveau drivers, and gently caress those. --edit: I suppose this should be moved to the Virtualization thread, anyway.

I'd been getting ready to pull the trigger on an i5 Skylake NUC. 4K@60Hz without relying on an iffy DisplayPort adapter would be nice, though, and even though I'm getting the thing mostly as an HTPC, it may be my only PC for a while, so a little extra oomph might not be a bad idea. My main concern is the extra power draw, since the PC will be in a closed media cabinet most of the time. Am I correct in thinking that idle/near-idle (e.g. I've read that HEVC decode averages like 3% CPU use) shouldn't be much higher power consumption than the lower-end NUCs?

Mobile Core i-series is a minefield. i5s are dual-core, except ones that have a Q at the end of the model number, which are quad-core. The dual-core mobile i5s are hyperthreaded, while the quad-core mobile i5s are not. All mobile i7s support hyperthreading, but similar to the mobile i5s, unless they have a Q or X in the model number they're dual-core. The mobile i7 quad-core line is generally close to par performance-wise with a similar desktop chip, unless thermal throttling kicks in. If thermal throttling kicks in though, your lap is already on fire because the Tcase for those is like 100 C.

Yea its like the only PC device with an Iris Pro that I can think of and its a reasonably good IGP chip from the looks of it. Even the Iris 540 isn't terrible. The thing about that Razer Core though is the price ($499!?!) and the fact that you are limited to PCI-E 3.0 @ 4X. Which if each PCI-E Standard is double the last, that means it is as fast as PCI-E 1.0 X16 which was good years ago, but throwing anything better than a 970 in there seems like it would bottleneck the hell out of it. Still faster than an IGP, but id like to see the reviews comparing different cards in there. The drop off after a 970 I would think would make a 980/980TI/Titan X look almost the same as it can't be fed enough to let loose. Will be interesting to see. What I really want to see though is the Core working with an XPS 13. Pair the best Ultrabook with Razer's Core and welp. Razer might have burned themselves by trying to make a Ultrabook but their Addon might get some good attention then. :/

Even the Iris 540 isn't terrible. ...but there were some outliers. I think Ryse was one, at higher resolutions it had a larger drop off. I think the assumption is that for compute heavy stuff (or something, where there's more communication back over the PCIe bus) it'll use up more of the bandwidth. Most stuff didn't at the time of that test but who knows in the future. Course realistically a bigger concern is probably just basic optimization to not run like poo poo before getting into any of that level of stuff. Tab8715 posted:I'm more concerned if the mobile i5 will be able to keep up with a modern GPU that's external. I imagine it'd depend on the game or whatever usage, and thermal constraints. Mobile i5s are generally dual core (albeit with hyper threading) so that might be a limiter if the game wants/needs a quad core CPU. Mobile i7 quads like that one should be fine. Both are generally clocked lower than the desktop counterparts which might be a concern, but I think that'd be more on the higher end of things (like I don't know how much stuff requires 3+ghz CPUs). And in both cases if the cooling isn't sufficient enough they'll have to throttle at some point. That'd be my biggest concern with a tight enclosure like that for a sustained load, and/or fan noise.

It takes up no space on my desk, supports 2 monitors and all the connectivity I need, and uses very little power. This new Skull Canyon model would actually be pretty capable for light gaming if I had to guess. I've played MGSV on a desktop with a Haswell low-power quad using integrated graphics and it was alright at 720p/low detail. A lot of older or indie games would work just fine too, and the mobile quad is going to be almost as fast as a desktop Skylake quad since it's not likely to be thermally throttled in that form factor. Of course, it probably won't compare to a discrete card costing $150+ but that card also uses as much power as the whole unit. You could add a Thunderbolt dock like the Razer Core, but by the time you do that you're using all of the power, money, and space of a real mini-ITX gaming desktop so you'd have to have another reason to go that route.

If you move pretty frequently even carting around a mini ITX case is bothersome (I am loathing the thought of moving my file server, laptops, and mini ITX desktop I use 90%+ of the time for video encoding or gaming), but I think that is one of the few situations where I'd recommend gaming laptops - you are hellbent on reducing the number of machines you have and are willing to pay for it. It's kind of a stretch for me though to try to figure out a very rational reason to have one despite potentially being in that market. I may want to give that new Razer laptop a try after selling my Macbook Pro and desktop, I dunno. One interesting scenario for having external GPUs is in a PC Room situation common in Asia where you can supply GPUs and network as an operator but everyone will bring their own machines with local storage and CPU. This could be cheaper for these folks to operate than to supply full-fledged PCs they have to actually maintain with software.

I'm looking at getting a new small laptop for use as a mobile device or around the house (my main system is a Broadwell i7 quadcore laptop I got on sale six months back, but while it's slim for a 15 inch, I really don't want to carry it around on trips or use it while I sit in a chair, it's desk only). The 11-inch laptop I'm looking at has an Intel m5-6Y54 CPU. The heaviest thing I'm likely to do on this is watch 1080p H.265/HEVC video while in a VOIP call (Skype or Discord), does the CPU sound adequate for that? (Especially since I think Skylake has hardware accelerated H.265 decoding.)
