[PATCH 02/19] drm: Pass pixel_format+modifier directly to drm_get_format_info()

[PATCH 02/19] drm: Pass pixel_format+modifier directly to drm_get_format_info()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Decouple drm_get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.

We may want to use drm_get_format_info() outside of the normal
addfb paths where we won't have a struct drm_mode_fb_cmd2, and
creating a temporary one just for this seems silly.

Done with cocci:

AFAICT you can also remove the forward declaration of struct 
drm_mode_fb_cmd2 from this header.

Best regards

[PATCH v2 02/19] drm: Pass pixel_format+modifier directly to drm_get_format_info()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Decouple drm_get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.

We may want to use drm_get_format_info() outside of the normal
addfb paths where we won't have a struct drm_mode_fb_cmd2, and
creating a temporary one just for this seems silly.

Done with cocci:

[PATCH 04/19] drm: Pass the format info to .fb_create()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Pass long the format information from the top to .fb_create()
so that we can avoid redundant (and somewhat expensive) lookups
in the drivers.

Done with cocci (with some manual fixups):

[PATCH v2 04/19] drm: Pass the format info to .fb_create()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Pass along the format information from the top to .fb_create()
so that we can avoid redundant (and somewhat expensive) lookups
in the drivers.

Done with cocci (with some manual fixups):

[PATCH 05/19] drm: Allow the caller to pass in the format info to drm_helper_mode_fill_fb_struct()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Soon all drivers should have the format info already available in the
places where they call drm_helper_mode_fill_fb_struct(). Allow it to
be passed along into drm_helper_mode_fill_fb_struct() instead of doing
yet another redundant lookup.

Start by always passing in NULL and still doing the extra lookup.
The actual changes to avoid the lookup will follow.

Done with cocci (with some manual fixups):

[PATCH 15/19] drm/msm: Pass along the format info from .fb_create() to drm_helper_mode_fill_fb_struct()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Plumb the format info from .fb_create() all the way to
drm_helper_mode_fill_fb_struct() to avoid the redundant
lookups.

For the fbdev case a manual drm_get_format_info() lookup
is needed.
