Running IGT tool

Q&A
1

I am trying to run IGT tool on Intel KBL NUC but all test cases are failing with below error

shiva@shiva /usr/libexec/igt-gpu-tools $ ./i915_query
IGT-Version: 1.23-NO-GIT (x86_64) (Linux: 5.0.9-741.native x86_64)

Subtest query-topology-unsupported: SKIP
Subtest query-topology-coherent-slice-mask: SKIP
Subtest query-topology-matches-eu-total: SKIP

before running test i had executed below steps
systemctl | grep -i getty

systemctl | grep -i gdm

sudo systemctl stop serial-getty@ttyS0.service

sudo systemctl disable serial-getty@ttyS0.service

sudo systemctl stop getty.target

sudo systemctl stop gdm

sudo systemctl stop gdm.service

sudo systemctl stop gdm.path

sudo systemctl disable gdm.service

sudo systemctl disable gdm.path

I get:

$ sudo /usr/libexec/igt-gpu-tools/i915_query

As non-root, I get Operation not permitted errors, as is to be expected.

How can i check who is holding DRM master ?

Thanks,

@shivasku I’ve merged the second thread created on IGT into this one.

Do we have any proper procedure to run igt-gpu-tools on bare metal clear Linux ?

there are multiple issues are observed, sometimes I am getting “No known GPU found” and sometimes “Can’t become DRM master, please check if no other DRM client is running”

This seems an issue with the tool, the hardware, or the kernel driver - Nothing particularly about ClearLinux from a quick glance that could influence this… We’ll need to poke some other teams about this issue and see if they can help - this may take a bit.
