drm: try harder to avoid regression when merging mode bits

2014-04-30T23:26:53+00:00

For QXL hw we really want the bits to be replaced as we change
the preferred mode on the fly, and the same goes for virgl when
I get to it, however the original fix for this seems to have caused
a wierd regression on Intel G33 that in a stunning display of failure
at opposition to his normal self, Daniel failed to diagnose.

So we are left doing this, ugly ugly ugly ugly, Daniel you fixed
that G33 yet?, ugly, ugly.

drm: remove drm_display_mode->private_size

2014-03-13T11:48:45+00:00

It' unused and there's also not really any way to make it work with
the current code. So better rip it out.

drm: polish function kerneldoc for drm_modes.[hc]

2014-03-13T11:48:44+00:00

- Tune down yelling RETURNS.
- OCD align all the parameters the same.
- Add missing kerneldoc, which also means that we need to include the
  kerneldoc from the drm_modes.h header now.
- Add missing Returns: sections.
- General polish and clarification - especially the kerneldoc for the
  mode creation helpers seems to have been some good specimen of
  copypasta gone wrong.

All actual code changes have all been extracted into prep patches
since there was simply too much to polish.

v2: More polish for the command line modeline functions.

drm/modes: drop maxPitch from drm_mode_validate_size

2014-03-13T11:48:43+00:00

Totally unused and actually redundant with maxX for display mode
validation. The fb helper otoh needs to check pitch limits,
but that is delegated into drivers instead.

drm/modes: drop return value from drm_display_mode_from_videomode

2014-03-13T11:48:42+00:00

It never fails and no one ever checked anyway.

drm/modes: remove drm_mode_height/width

2014-03-13T11:48:41+00:00

There's a neat FIXME asking whether this is really need. I'd
say really no.

drm: extract drm_modes.h for drm_crtc.h functions

2014-03-13T11:48:41+00:00

I want to also include kerneldoc from the header (for static inline
functions and structs), but fishing the right pieces out of a giant
header is a real pain. So split things out.

Note that it's not a really clean header with sane include orders, but
given's drm historical knack for giant headers detangling this is a
major task.

v2: Also extract struct drm_cmdline_mode.
