[PATCH 1/3] [v2] drm: Add new DRM_IOCTL_MODE_GETPLANE2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Originally based off of a patch by Kristian.

This new ioctl extends DRM_IOCTL_MODE_GETPLANE, by returning information
about the modifiers that will work with each format.

It's modified from Kristian's patch in that the modifiers and formats
are setup by the driver, and then a callback is used to create the
format list. The LOC was enough difference that I don't think it made
sense to leave his authorship, but the new UABI was primarily his idea.

Additionally, I hit a couple of drivers which Kristian missed updating.

It also contains a change requested by Daniel to make the modifiers
array a sentinel based structure instead of a sized one. Upon discussion
on IRC, it was determined that having an invalid modifier might make
sense in general as well.

v2:
  - Make formats uint32_t, and use an offset, see the comment in the
  patch. Add a WARN_ON and early bail for when there are more than 32
  formats. (Rob)
  - Name format_modifiers annotation properly (Ville)
  - Remove DRM_DEBUG_KMS (Ville)
  - make flags come before count in struct (Ville)
