Hi all,
If drm/panic is enabled, a user-friendly message is shown on screen when
a kernel panic occurs, together with an ASCII art penguin logo.
Of course we can do better ;-)
Hence this patch series extends drm/panic to draw the monochrome
graphical boot logo, when available, preceded by the customary fixes.
Changes compared to v1:
- Rebase against today's drm-misc-next, where drm_panic is broken on
all current drivers due to an uninitialized pointer dereference.
Presumably this was only tested with an out-of-tree driver change?
- New fixes [1/7], [3/7], and [4/7],
- New cleanup [5/7],
- Inline trivial draw_logo_mono().
This has been tested with rcar-du.
Thanks for your comments!
