This might be a known python issue. What is the output of "python3 --version"?

This is actually rather simple, you'd specified conflicting arguments:
"-t igt/gem_pread/basic" and "-x igt/gem_pread/basic"

-t tells piglit to *only* run tests that match igt/gem_pread/basic, and -x tells
piglit to *not* run any tests that match igt/gem_pread/basic. You should drop
the "-x ..." and it should do what you want.
