I would like to test my hardware and I am surprised the ebuild does not install the testsuite as well. While I admit the binaries themselves might be usefull on their own for skilled users, but others it is more usefull to have the testsuite and runn the stress tests. Quiting from README: tests/ This is a set of automated tests to run against the DRM to validate changes. Hopefully this can cover the relevant cases we need to worry about, including backwards compatibility. Run this tests with "make test" as root from this directory. Note that no other drm clients (X server) may run. That means ebuild must install the generated tests/Makefile as well.
If I understand correctly, these tests do not test the hardware, but instead the kernel driver and DRM interface.
These are really for developers or debugging. They're not really meant to be installed.
Debugging is indeed the *main* reasone because I install intel-gpu-tools.
sounds like a good use for USE=debug then
The test programs for DRM driver development are now installed if you set USE="test-programs". However these were not designed to run outside their build directory and may or may not work. testdisplay for example hardcodes the path to pass.png in the binary and will probably not run correctly.
