[igt-dev] [RFC PATCH v7 3/5] lib: ioctl_wrappers: check GET/SETPARAM ioctl and build active engine list

[Andi Shyti]

The igt_require_gem_engine_list() is called whenever the test
wants to use the GET/SETPARAM ioctls.

The function checks whether the GET/SETPARAM are implemented in
the running kernel and stops the test in case these commands are
not supported.

At the first call it creates the current engine list as
implemented in the gem_init_engine_list() function.
