If our immediate reaction to tests failing on a new architecture is to
disable them, then the tests have no purpose.

As I asked before: do mutter-based window managers *work* on loong64?

At the moment, the only evidence we have for whether this package is
usable on loong64 is whether its tests pass.

This is a problem with your test environment: please set up /dev correctly.
If you had read the log file, you would already have seen this.

This is an assertion failure: by definition, it should not occur. The
first assumption when a test fails should be that the failing test
indicates that the software under test is broken in some way on the
relevant architecture.

It might be a bug in mutter, or in Mesa, or in some related component,
or it might even be a bug in the test - but disabling the test and hoping
it wasn't important is not a solution.

Please investigate why this assertion is failing: perhaps your
build environment's OpenGL driver differs from the OpenGL drivers on
architectures where this works correctly?

Same as -gl3 (and probably the same root cause).

Again, this assertion failure indicates a bug somewhere; please investigate.

A file that should have been readable was not readable. Please investigate
why.
