rk3399 and Visual Output Processor 2 (VOP2)

[swan]

Hello everyone!

That is VOP2 and why it is better than VOP?

I find some information about VOP v1
Can anyone show info about VOP2?

----

According this news VOP2 is used by Rockchip SoCs starting with the RK3566 / RK3568 SoCs.
Do the rk3399 is supported it?


Thanks

I have no idea what VOP is, but my RockPro64 logs have:

Code:

Appears to be supported by the kernel?

Thanks for your reply.

VOP and VOP2 are supported by the kernel, but it configure from the device tree (if i understand clearly).

In my case looks like default configuration is fault if more than one video output is used.

More over, i don't shure how it boost in highload in few video output (2 or 3) and do video output can work without any display controller eat.
