Hi Kieran, Hi Laurent, We are planning to put some efforts to improve and add, on top of the RCAR CMM patches[1] and upstream them. Following are the add-ons/improvements planned. If there are some activities with respect RCAR CMM, are ongoing already in upstream, we are happy to be involved in it and can spare efforts. 1. Double buffering support for CLU, LUT tables. 2. Add worker thread in rcar_cmm to apply the table settings. To apply the CLU settings time taken is around ~7ms. This looks a bit high and more importantly it just blocks the compositor. 3. With the patches[1] I see that CLU settings are written to registers but, the display does not show any change. Also, I see a short freeze on the display. This needs to be resolved. Also we have some patches for weston drm-backend which can set the 3DLUT, but they could not be up-streamed because drm object properties "CUBIC_LUT" and "CUBIC_LUT_SIZE" are not the standard ones yet.
