Subject[PATCH v2 0/4] KUnit tests for RGB565 conversion
Date
Hello everyone,

This series is a follow up of the XRGB8888 to RGB332 conversion KUnit
tests.

The first patch fixes a bug reported by David Gow in the XRGB8888 to
RGB332 tests.
Note that the fix is required for this format because internally, the
drm_fb_xrgb8888_to_rgb332_line() function, calls le32_to_cpu().
The other *_line() functiones don't change the endian. That's why the
RGB565 tests don't need to make any endian conversions.

I'm not sure whether this inconsistency handling the endian could be
considered a bug or not, but at list it is confusing. It'd be
interesting to hear the opinion of the maintainers on this topic.

Patches 2 and 3 make the test generic and the last one tests
drm_fb_xrgb8888_to_rgb565().

Best wishes,
José Expósito

Changes since v1:

- Fix a bug reported by David Gow in the XRGB8888 to RGB332 tests
- Simplify the test structure as suggested by David Gow
- Add Tested-by Tales L. Aparecida and Acked-by Thomas Zimmermann
- Fix link in the last patch (Thomas Zimmermann)

José Expósito (4):
drm/format-helper: Fix test on big endian architectures
drm/format-helper: Rename test cases to make them more generic
drm/format-helper: Support multiple target formats results
drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_rgb565()
