[PATCH v2 0/7] drm/gud: Add some more pixel formats

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

 



Hi,

This adds some more pixel formats and gives the user the ability to
choose the xrgb8888 emulation format.

Pixel formats:
R8: For greyscale e-ink displays
RGB332: For e-ink displays and some niche displays
RGB888: Same color depth as XRGB8888 but the smaller buffer gives better
fps

Changes since first version:
- RGB332: Support Big Endian in the emulation (Daniel)

Noralf.


Noralf Trønnes (7):
  drm/fourcc: Add R8 to drm_format_info
  drm/format-helper: Add drm_fb_xrgb8888_to_rgb332()
  drm/format-helper: Add drm_fb_xrgb8888_to_rgb888()
  drm/gud: Add GUD_PIXEL_FORMAT_R8
  drm/gud: Add GUD_PIXEL_FORMAT_RGB332
  drm/gud: Add GUD_PIXEL_FORMAT_RGB888
  drm/gud: Add module parameter to control emulation: xrgb8888
