Subject: [PATCH v4 0/9 drm: rcar-du: Add Color Management Module (CMM)
Date: Fri,  6 Sep 2019 15:54:27 +0200
Message-ID: <20190906135436.10622-1-jacopo+renesas@jmondi.org> (raw)

[ Ugh, sorry for the double sending, but I forgot --cc-cover to git-send
  email and the series has not been delivered to the mailing lists.
  Sorry about that. ]

Hello, new iteration of CMM support, with quite a few changes compared to
v3:

References:
A reference to the v1 cover letter, with some background on the CMM is
available here:
https://lkml.org/lkml/2019/6/6/583
v2:
https://lore.kernel.org/linux-renesas-soc/20190706140746.29132-10-jacopo+renesas@jmondi.org/
v3:
https://lore.kernel.org/linux-renesas-soc/20190825135154.11488-1-jacopo+renesas@jmondi.org/

Change log:

*Bindings/DT:
- Rebased on renesas-devel-2019-09-03-v5.3-rc7
- Bindings converted to yaml: thanks Laurent for help
- s/'cmms'/'renesas,cmms'/ in DU bindings as suggested by Rob
- s/cmm-<soctype>/<soctype>-cmm/ as suggested by Geert
- squashed CMM addition for Gen3 SoCs in a single path at the end of
  the series

*CMM/DU:
- Only accept fully populated LUT tables, remove the 'size' from the CMM
  configuration structure as suggested by Laurent
- Simplify CMM configuration logic: only rely on color_mgmt_changed flag and
  unconditionally provide a populated LUT table to the cmm_setup() function
- Protect against probing order inversion (DU is operation while CMM still has
  not been probed) by adding rcar_cmm_init() operation as it is done for VSP as
  suggested by Laurent
- Add CMM function stubs to fix compilation erros when CONFIG_DRM_RCAR_CMM is
  not selected
- Minors in the CMM driver as suggested by Laurent
  - Remove per-soc strings
  - Make comments style consistent (not using /** anywhere in the .c file,
    unify comment style)
  - s/rcar_cmm_load()/rcar_cmm_write()/
  - Squash cmm configuration and suspend/resume support in rcar_du_kms.c

Testing:
I have tested by injecting a color inversion LUT table at test program
initialization:
https://jmondi.org/cgit/kmsxx/commit/?h=gamma_lut&id=3c6af4db165e5b3dc8996f0a288746c35dbb1cb9
And by changing the CMM content to switch between a color inversion table
and a linear table every 50 frames:
https://jmondi.org/cgit/kmsxx/commit/?h=gamma_lut&id=fe178a43861da7c8e79618e2a13fa0f19dbcd03d

Pretty happy with the result, which seems to be consistent across system
suspend/resume.

Testing with real world use cases might be beneficial. Rajesh are you still
interested in giving this series a spin?

Thanks
