I've been looking into building an i915 module so I can try CONFIG_DRM_I915_LOW_LEVEL_TRACEPOINTS=y to get at the low level information using VTune. I tried the instructions in https://software.intel.com/content/www/us/en/develop/documentation/vtune... and get the following:

N: See apt-secure(8) manpage for repository creation and user configuration details.
I'm already worried I'm gonna brick my laptop doing this, so I stopped. I then thought it might make sense to point to another source repository so I enabled "deb-src http://us.archive.ubuntu.com/ubuntu/ bionic main restricted" in /etc/apt/sources.list. (maybe this is doomed, but it seemed like a reasonable try.) It didn't help. The result was:
root@t570:~/OneAPI# apt build-dep linux linux-image-$(uname -r) Reading package lists... Done Picking 'linux-signed-hwe' as source package instead of 'linux-image-5.3.0-53-generic' E: Unable to find a source package for linux-image-5.3.0-53-generic
So, I'm kinda stuck. Anyone got some advice for me? Is building a new i915 module really worth it?
