From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
I got sick and tired of staring at the line noise produced by drm.debug=0x1e,
so I decided to give the crtcs and planes human readable names. Each driver
can give whatever names it wants, and for i915 I gave something that makes
some sense w.r.t. to the spec.
The only magic gotcha here is that if the driver dynamically allocates the
name, it must be careful around drm_{crtc,plane}_cleanup() cause those
guys just memset the entire structure to 0. I didn't want to put the kfree()
into the cleanup functions to avoid having to kstrdup("") in the fallback
case or forcing drivers to always use a dynamic allocation.
Ville Syrjälä (6):
drm: Add crtc->name and use it in debug messages
drm: Add plane->name and use it in debug prints
drm/i915: Use crtc->name in debug messages
drm/i915: Use plane->name in debug prints
drm/i915: Set crtc->name to "pipe A", "pipe B", etc.
drm/i915: Give meaningful names to all the planes
