Intel GPU tools crash with "Couldn't map MMIO region"

[Robert Markovski]

Trying to run anything in intel-gpu-tools (tested intel_gpu_top, intel_gpu_time and intel_backlight) on my laptop (which has hybrid graphics, GTX 760m (proprietary nvidia driver not installed right now) + Intel 4th gen iGPU) as root yields the following output:

I have exactly the same "Couldn't map MMIO region: Operation not permitted" problem with Ubuntu 14.04.5 with 1.3-0ubuntu2.1 build. My CPU is Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz on my ASUS VivoMini PC.

[Robert Hooker (sarvatt)]

They need to be run under sudo. also the intel-gpu-tools in 14.04 shouldn't have support for an i7-7700.

[John Yang (johnyang2000)]

Yes I did run with sudo. The error message is different without sudo. I think the new 14.04.5 fixed a lot of problems with the new intel cpu. At least it fixed all my graphics card driver issue in one shot. However, how do I find out what is supported with intel-gpu-tools?

[John Yang (johnyang2000)]

but of course the intel-gpu-tool for trusty hasn't been updated since 2014 so likely it doesn't support i7-7700 (released in 2017) as you described. However it's the same MIMO error message I am getting. I'm hoping the same fix will be updated to the version for trusty.

Status changed to 'Confirmed' because the bug affects multiple users.

I've hit this too on 18.04.
It may be related to kernel lockdown in UEFI secure boot.
