[PATCH v2 0/3] drm/panic: Add kunit tests for drm_panic

[Jocelyn Falempe <jfalempe@redhat.com>]

This series adds some kunit tests to drm_panic, and a debugfs interface to easily test the panic screen rendering at different resolutions/pixel format.

The kunit tests draws the panic screens to different framebuffer size and format, and ensure it doesn't crash or draw outside of the buffer.
However it doesn't check the resulting image, because it depends on other Kconfig options, like logo, fonts, or panic colors.

v2:
 * Use debugfs instead of sending the framebuffer through the kunit logs. (Thomas Zimmermann).
 * Add a few checks, and more comments in the kunit tests. (Maxime Ripard).

Jocelyn Falempe (3):
  drm/panic: Rename draw_panic_static_* to draw_panic_screen_*
  drm/panic: Add kunit tests for drm_panic
  drm/panic: Add a drm_panic/draw_test in debugfs
