Subject: [PATCH] backend/native: Don't warn on EACCES if headless
|
|
|
|
Since commit 1bf70334 "tests/runner: Make test runner use the headless
|
|
backend", tests are run with the native backend in headless mode, which
|
|
will attempt to open each GPU and show a warning (fatal during tests)
|
|
if it cannot.
|
|
|
|
However, in headless mode we might not be logged in on any seat (for
|
|
example we might be logged in via ssh instead), which means we might
|
|
legitimately not have permission to use any GPUs, even if they exist.
|
|
Downgrade the warning to a debug message in this case.
|
