You want to pass-through the Intel iGPU, yet your list of blacklisted modules only lists modules for Nvidia and AMD. See the issue? hint: i915. At some point you seem to have tried it on the kernel commandline, but then commented it out again. Right? Next question: Did you pass the PCI-id of...

Forget about the ASPEED! This is the BMC graphics, which only has very rudimentary graphics functions. No video-codec and/or 3D-acceleration. So, scratch that thought! However, you might be lucky: Your CPU does actually have an integrated GPU. See here...

Had an effect just yesterday, that sounds very similar. For me, recreating the EFI-partition without the "Pre-Enroll keys" option solved it. Found the hint online and worked like a charm. Don't know the exact background. As I wrote, just found the information online.

Just FYI, after having tried the opt-in 5.19 kernel some time ago (see https://forum.proxmox.com/threads/opt-in-linux-5-19-kernel-for-proxmox-ve-7-x-available.115090/#post-498817) I now gave the opt-in 6.2 a try. Behavior seemed to be indentical to my experience with 5.19. In general it seems...

See here for how to retrieve the vbios file: https://pve.proxmox.com/wiki/PCI_Passthrough Additional hint: In order to save the legacy vbios, you will most likely need to make sure, that CSM is enabled in your system BIOS and that the "Video" Sub-Option for the CSM-ROM settings is actually set...

Try to use the saved Legacy VBIOS file (option "romfile=") and use legacy boot on your VM. This seems to have the best bet to get this working. At least it does work for my own Win10 VM on CoffeeLake.

OK, so you can scratch my request, as I obviously did not know about that option. Just tested and works fine with 5.15 and 5.19. Now that you mentioned it, I think I remember having read about it some time ago, but then forgot to try it out. Thanks anyway! Much appreciated input.

BTW, another quick question, about the upcoming kernel 5.19: Is there a chance to solve that dreadful simplefb dilemma with the 5.19 configuration, concerning simplefb. I have a Proxmox CoffeeLake system with passed-though iGPU. Up until 5.13 this worked (and still works) beautifully. However...

Tried all three kernel parameters with the current 5.19 pve-kernel. Sadly none brought back the previous functionality, as seen on 5.15. I do not have measurements, but it felt like "voluntary" was the worst, followed by "full" and the most acceptable (yet not nearly as good as on 5.15) was "none".

Just tried the Kernel 5.19 on my Xeon E5 v4 system with passed through GTX 980 Ti under Windows. Experienced massive lags/delays in games. Same setup runs smooth if I switch back to 5.15. I guess there still is work to do. BTW, nothing obvious in the system log, when the delays hit. And the...

Just FYI, the workaround did work perfectly for a Nvidia GTX980 Ti. However, on my other system, where the CoffeeLake iGPU gets passed-through, it did NOT work. I would guess because the GPU is an internal function there, instead of an external card. When the workaround is applied there, it...

Set PCIe speed for all hardware connected through the "bifurcator" to Gen2 or Gen1. If it runs then, you have a signal integrity issue, concerning the operation on PCIe Gen3, in combination with the "bifurcator". Remember, the more transitions over connectors the signals have to make, the worse...

Also would like to thank StephenM64 for his suggested workaround. Although it seems kind of hacky, it does indeed work. Confirmed here with a Nvidia GTX GPU. Non-working for pass-through by default, due to the mentioned "BAR" issue, with Kernel 5.15. After applying the workaround, it is...

Tim, are you sure, that grub is even used? Have a look at "/etc/kernel/cmdline", edit as required and then run "pve-efiboot-tool refresh". Besides, follow the usual how-tos.

And last update: The patch from kernel org worked flawlessly on the 5.9.1 kernel of my debian testing VM.

Could be, that I just found the explanation myself: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/i915/i915_drv.h?h=v5.10-rc3&id=8195400f7ea95399f721ad21f4d663a62c65036f Edit: Mixed something up. This will need to find its way into the kernel of the...

Hi guys, I have a Intel CoffeeLake system (i3-8300 on C246 chipset), with installed Proxmox VE 6.2 (latest update status) that I wanted to use with several containers and one VM with fully passed-through i915 graphics. Found a setup, that is nearly fully working (vm conf excerpt): ...
