2022-06-29tests: Convert to formatted string literalsLaurent Pinchart
Use formatted string literals to replace legacy printf-style string formatting. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2022-06-29tests: Replace double quotes with single quotesLaurent Pinchart
The code base mixes single and double quotes. Standardize on single quotes except for triple-quoted strings (to match the PEP8 coding style) and where the string contains single quotes to avoid the need to escape them.

2020-08-08tests: crc: Compute reference CRC values and compare themLaurent Pinchart
Instead of only checking that the CRC value is constant, compute the expected CRC value, and compare it to the hardware-generated CRC. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-08-08tests: crc: Introduce Composer classLaurent Pinchart
The Composer gathers the computation of planes position. It is currently only used to configure the planes. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-08-08tests: crc: Disable CRTC regarless of test statusLaurent Pinchart
The CRTC should be disabled when the test completes, regardless of whether it succeeds or fails. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2020-08-08tests: crc: Fix AtomicRequest usageLaurent Pinchart
Commit 3cd7e6814cea ("kmstest.py: Fix CRTC disabling") modified the CRC test to use the kmstest.AtomicRequest class, but failed to pass the correct argument to the constructor. Fix it.

2019-06-19kmstest.py: Add output_connectors() helper to skip writeback connectorsLaurent Pinchart
Add a generator method to the KMSTest class to enumerate all non-writeback connectors, and use it through tests. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>
2019-06-18kmstest.py: Fix CRTC disablingLaurent Pinchart
The KMSTest.atomic_crtc_disable() method deactivates a CRTC but doesn't fully disable it, which requires setting the MODE_ID to 0. Furthermore it doesn't de-associate the CRTC from connectors and planes, which causes atomic check failures as a fully disabled CRTC can't be associated with connectors. It can also lead to the next test failing due to resources still being allocated to the CRTC. To fix this, introduce an AtomicRequest class that wraps around pykms.AtomicReq, and stores a copy of all the properties. When the request is committed the properties are added to a global state, which is then used to locate and release connectors and planes associated with the CRTC in KMSTest.atomic_crtc_disable().
