Thank you for providing this information. I was cross compiling for an x86 hardware where ctm and gamma_lut are supported. It was not possible to run "make check" with reasonable efforts spent. Now fixed the stuck problem with version v3. Also tested on Ubuntu and on a custom hardware.

Currently we do not have any DRM-specific tests. It is possible to choose the backend to run with, see https://wayland.freedesktop.org/testing.html , and if a test is DRM-specific, it should skip on other backends.

I basically execute three commands (within weston's root dir): $ ./autogen.sh --prefix=$WLD $ make $ make check The output for `autogen.sh` (which is the same regardless patches application) is attached. All tests in suite run fine (24 passed, 1 skipped) when running these commands without the paches. I'm applying the patches by downloading the mbox and `git am patches.mbox`. Are you able to run all tests in suite by just `make check` after building the project?

Hi Matheus, Thank you for the test. Weston needs to be rebuilt. But, no new library versions dependencies. I did not run though other Weston tests. Just running gamma and ctm test works at my desk. The way I ran tests was by modifying Weston.ini to add gamma-test.so and ctm-test.so to modules. I will run now all the other test in sequence, by modifying Weston.ini. Any additional hint to reproduce this problem will help me to fix the issue faster.
