Hi, While working with CRTC color related properties (gamma and CTM for instance) and making them persistent over suspend-resume cycle it occurred to me if I am just wasting resources by storing the property values in the driver and restoring them in dev_pm_ops runtime_resume().. Wouldn't it work if I would just: 1. Add a flag in the driver to indicate that the context may have been lost since the previous atomic commit and set in runtime_resume(). 2. And write the color properties to HW if the context lost flag is set even if the drm_crtc_state color_mgmt_changed is false. The color property values are there despite the color_mgmt_changed == false, aren't they? Best regards, Jyri -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
