[PATCH libdrm 00/10] Add C8, 30bpp and FP16 support to modetest

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

 



This series improves the pattern generation logic to support additional
formats, as well as a new "gradient" pattern (see patch comments on why
I found it useful).

Furthermore, these formats are piped through to modetest, including the
ability to set a gamma table, which is necessary for the C8 indexed
format.

This was tested on nouveau, and used for bring-up of the C8, XB30, and
FP16 formats on the NVIDIA hardware that supports these.

Ilia Mirkin (10):
  util: add C8 format, support it with SMPTE pattern
  util: fix MAKE_RGBA macro for 10bpp modes
  util: add gradient pattern
  util: add fp16 format support
  util: add cairo drawing for 30bpp formats when available
  modetest: don't pretend that atomic mode includes a format
  modetest: add an add_property_optional variant that does not print
    errors
  modetest: add C8 support to generate SMPTE pattern
  modetest: add the ability to specify fill patterns on the commandline
  modetest: add FP16 format support
