xengt module cannot be added

[The-Wind]

Running sudo modprobe xengt gives me this: modprobe: ERROR: could not insert 'xengt': Invalid argument.

Tried on Linux Mint 18.3 on gvt-stable-4.14 branch

Hi, you want to run XenGT or KVMGT? Can you provide your /boot/config-4.14.15+? Make sure XenGT or KVMGT related modules are existed.

Here you go

I merely just followed the guide as I don't have an in-depth Linux knowledge. I want to run XenGT as I have a 4th gen (Haswell) CPU.

I did do something wrong though; I was not booting Xen in EFI properly. I used multiboot linux initrd instead of multiboot module module because I think that doesn't work in EFI.

I'm apparently supposed to use multiboot2 module2 module2 but that still didn't work. Someone claimed the fix is to upgrade the grub bootloader at least 2.02 beta 3 (I have beta 2). So I will try that.

Anyways, could not booting Xen properly be the issue for why the XenGT module doesn't load?

GVT-g only support 5, 6, 7th gen, not support Haswell. ☺ From: The-Wind [mailto:notifications@github.com] Sent: Wednesday, April 25, 2018 2:14 PM To: intel/gvt-linux <gvt-linux@noreply.github.com> Cc: Xu, Terrence <terrence.xu@intel.com>; Comment <comment@noreply.github.com> Subject: Re: [intel/gvt-linux] xengt module cannot be added (#34) Here you go<https://github.com/intel/gvt-linux/files/1945621/config-4.14.15.txt> I merely just followed the guide as I don't have an in-depth Linux knowledge.

I was under the impression that 4th gen was supported in XenGT according to this:

Intel GVT-g is a full GPU virtualization solution with mediated pass-through, starting from 4th generation Intel Core(TM) processors with Intel processor graphics. A virtual GPU instance is maintained for each VM, with part of performance critical resources directly assigned. The capability of running native graphics driver inside a VM, without hypervisor intervention in performance critical paths, achieves a good balance among performance, feature, and sharing capability. GVT-g for Xen hypervisor is XenGT.

I suppose the GVT-g Setup Guide says otherwise but I figured I take a shot at it.

The module now loads. I confirm that I needed to boot Xen gz properly with multiboot2 module2 module2 in the grub menuentry. I had to build grub from source because the one in Mint's repo is outdated.

Hello, only our old 4.3 kernel XenGT branch support 4th gen, which without upstream. The upstream code start from 5th gen. ☺ From: The-Wind [mailto:notifications@github.com] Sent: Thursday, April 26, 2018 12:18 AM To: intel/gvt-linux <gvt-linux@noreply.github.com> Cc: Xu, Terrence <terrence.xu@intel.com>; Comment <comment@noreply.github.com> Subject: Re: [intel/gvt-linux] xengt module cannot be added (#34) I was under the impression that 4th gen was supported in XenGT according to this<https://01.org/igvt-g/blogs/wangbo85/2017/intel-gvt-g-xengt-public-release-q32017>: Intel GVT-g is a full GPU virtualization solution with mediated pass-through, starting from 4th generation Intel Core(TM) processors with Intel processor graphics.
