[PATCH 00/19] drm: Eliminate redundant drm_format_info lookups

[Ville Syrjala]

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

I noticed a bunch of redundant (and rather expensive) drm_format_info
lookups in some traces recently. This series is an attempt to eliminate
them.

Ville Syrjälä (19):
  drm: Pass pixel_format+modifier to .get_format_info()
  drm: Pass pixel_format+modifier directly to drm_get_format_info()
  drm: Look up the format info earlier
  drm: Pass the format info to .fb_create()
  drm: Allow the caller to pass in the format info to
    drm_helper_mode_fill_fb_struct()
  drm/malidp: Pass along the format info from .fb_create()
    malidp_verify_afbc_framebuffer_size()
  drm/gem: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/gem/afbc: Eliminate redundant drm_get_format_info()
  drm/amdgpu: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/armada: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/exynos: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/gma500: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/i915: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/komeda: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/msm: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/tegra: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/virtio: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm/vmwgfx: Pass along the format info from .fb_create() to
    drm_helper_mode_fill_fb_struct()
  drm: Make passing of format info to drm_helper_mode_fill_fb_struct()
    mandatory
