Have you updated your mesa from apt source?
Like the post you linked said. You have to keep mesa version with coolpi ppa if you want hardware accelaration.
Kernel 5.10 is using panfork, Which is specific mesa version needed.
If you want newer version mesa you have to switch to kernel 6.10 and use panthor driver instead.

There are many models in the driver kernel source code of the camera, but this can only ensure that the system recognizes the nodes. For the camera part, it is more important to debug the ISP effect file, which is highly specialized and difficult for those who have not been exposed to it to handle.

At present, the mainline kernel EDP interface is not supported. The CM5-LAPTOP configuration has been submitted for mainline review and should be released soon.
