10 bit HDMI output

Konrad.Z

I'm considering using FireFly RK3399 board to use in my project where i need HDMI output with 10 bits to run a 4K LCD module. In the datasheet or RK3399 there is a information about supporting 10 bit for 4K on HDMI, but what about software ? Is it support or I will have a problem with it ?

 HDMI interface
 Support 480p/480i/576p/576i/720p/1080p/1080i/4k
   Support RGB/YUV420(up to 10bit) format
Cut it from http://www.t-firefly.com/downloa ... t_V0.7_20160219.pdf

Thanks! I know that RK3399 chip hardware support it but what about software side ? Does linux distribution and drivers that you provide allow to use it ?

For example: I was thinking of using nvidia tegra chip for driving 30 bpp (10 bit per pixel) LCD, but I find out that their hardware allow it on every video output, but on software site there were limitation on linux and in the end you can drive only 8 bit per pixel (24 bpp).

Software will be updated later, I saw rk3399 newest sdk had already support 10bit from Rockchip SDK.
