From: Maxime Ripard @ 2026-10-21 14:29 UTC (permalink / raw)
  To: igt-dev; +Cc: Maxime Ripard

The kernel gained a DRM_MODE_ATOMIC_RESET flag that resets KMS object
states to their defaults before applying the properties carried in a
commit. This flag is advertised through DRM_CAP_ATOMIC_RESET.

When the commit comes from a lessee, only the objects part of its
lease are reset, and every other object is left untouched. Indeed, a
lessee has no access to the objects outside of its lease, and must not
be able to affect them.

Add a test covering both the basic semantics of the flag and its
interaction with leases:

- cap-atomic-reset: the capability is reported.
- invalid-reset-with-async: ATOMIC_RESET rejects PAGE_FLIP_ASYNC.
- reset-test-only: TEST_ONLY succeeds without altering committed
state.
- reset-disables-crtc: a bare reset brings ACTIVE back to 0.
- reset-with-crtc-enable: explicit properties in the same commit
override the reset defaults.
- lessee-reset: a reset from a lessee shuts down its leased pipeline.
It is run with the planes added implicitly by the kernel, with only
the primary plane, and with all the planes of the CRTC.
- lessee-reset-unleased-pipe: a reset from a lessee leaves the
pipelines outside of its lease untouched.

The latter requires two pipelines, and will be skipped on the default
vkms instance.
