Nvidia optimus kvm. Update your graphics card drivers today. The objective is to enable nvidia gpu of an optimus based laptop all the time and use it for every single activity. This is stretch with the bios set to nvidia optimus and os aware. You ll see disabling iommu for graphics on this chipset in the dmesg and the integrated gpu will not be visible to vfio.

Hi guys i m making this post to show what i ve done endured over the last few weeks while playing with qemu kvm intel gvt g and an nvidia discrete graphics chip on a hp laptop in a hope to help people trying to find a way to get the damn beast working without dual boot and get insight over problems i m currently unaware unable to fix. Kvm vfio don t care about and especially red hat developers don t give a fuck about nvidia dick policies so here we go. This no longer works for intel broadwell integrated gpus as of linux 5 4.

Yeah looks like kvm it is. I have a w530 lenovo with the nvidia optimus. In the combination of intel nvidia optimus nvidia drivers are in charge of moving the workload to dgpu. Normally a modified driver nvidia optimus or bumblebee on linux exposes the results of a window running on the nvidia card as a texture to the intel graphics.

Thanks to alyssais for pointing this out. Please do not use this guide if you want to render your desktop using the integrated gpu and specifically select applications to be rendered using the nvidia gpu. Looks like i ll have to give it a whirl to be sure. But nvidia drivers won t accept intel gvt g into the combination and optimus won t be enabled.

First things first my specs. Intel video k2000m i am trying to pass the k2000m to the windows 10 virtual machine. We can probably patch nv acpi rom method in kernel nvidia nv acpi c to simply return our vbios from a hard coded buffer just for testing. I feel like i am so close but so far.

Which means games will run on the integrated graphics unless the game engine proactively detects and uses the dgpu. Nvidia websites use cookies to deliver and improve the website experience. Everyone can use passthrough on that hardware.
