Thank you :)

Hey Duke3d dude! :)
How's the overall experience with amd gpus?
C ya!

You're welcome
Before this HD 7950, I had a GTX 770 and honestly, I prefer the AMD card becaust it's easier to configure on Linux and because it's compatible with passthrough. But there is almost no differences except the price between AMD and Nvidia if you don't use Linux.

Care to elaborate?

Right. I let you live, for now ; )
I was kind of hoping I can get rid of NTFS, move my 7 to VHD and play some win games in vm.
No go with my laptop..

Saw similar post on Russian linux.org.ru site. Link.
On one monitor he is reading the website (linux.org.ru), on another - playing "Assassin's Creed: Black Flag".

Congrats to OP. Good job! :)

You are forced to set guest CPU to "Nehalem" (core2duo family) to be able to install Windows 10 and, it didn't detect a lot of my hardware. It even halted with something like "THREAD_DEVICE_DRIVER TIMEOUT". With 7, it's easier, you have no specific options to set.
Don't give up! And next time, buy an AMD :D
Thanks!

I didn't go linux to give up : D
I am sure there is a way to make things work my way, just not discovered yet ; )
No amd for me though, I imagine I'd need a bigger dynamo..

With optimus it's like... Impossible. Sure, there is a way to disable it on some motherboards making igpu and gpu separated in lspci and then you'll be able to bind it using vfio-pci. But, is your CPU IOMMU compatible? Does your mobo enable VT-d? And even if you finally succeed, I assume that there is no separated output for your nvidia card. You'll be forced to use spice or vnc and they aren't powerful enough to play. So if there is a way, it wasn't discovered yet ;) ;)

Hmm, interesting. I don't suppose you know if that processor setting would be applicable to both AMD and Intel, or if it only is a concern on Intel?
I bet there is. An external PCI Express chassis and graphics card in it should do it, methinks. I mean, you won't get full PCIe 16x speed, but it should work.

SHAMELESS UPDATE:

Here's my self-compiled kernel for Debian 8.3 Jessie. What are the differences? pci_stub and vfio-pci are included and not modules anymore, no need to manually load them with initrd. ACS and i915 patched for every mobos that don't have a single group containing only the vga card to passthrough. Newer kernel (3.18). GCC optimizations, added some useful drivers. REMOVED KVM_INTEL MODULE, don't use it if you have an intel cpu.

If you want to do some passthrough, use it, don't waste your time on some -already made- kernel patching ^^

My boot options:

My VM script:

sudo qemu-system-x86_64 -enable-kvm -M q35 -m 8192 -cpu host \

If you have any questions, PM me ;)
The Nehalem family is for all CPUs, AMD and Intel ^^

And also yes, I completly forget about those external PCI Express Chassis, my bad....

nvm

That's what I said : D
According to ark there is no VT-d for me..
I've heard about external PCIe, not very portable solution.
Anyway, really good job!

Arf, that moment when you really can't enjoy your laptop because some shitty engineers thought that it would be too difficult for the "normal" user to add some cool functions.

h
Nah, I can live with that. Besides, ark can be wrong ; p
But passtrough won't work for me anyway. Not on the laptop..
And honestly, I am completely fine with my hardware : )
