I checked KD5+wayland, it works well. The interface is fast, there are no freezes on the video when moving the mouse cursor, as on x11. Glmark2 showed more than 400 units. test images from KDE5 on the site.

This kernel will not work in LE. It does not support panfrost (not to be confused with panfork, which has nothing to do with the main core). LE uses only the main core exclusively, it has completely removed support for mpp and BSP RK cores.

No. panfrost (open source) is in the main kernel 6.x (appropriate APIs are needed, which are not in the BSP core). In the core of RK BSP there is version of mali\bifrost (uses closed binary libraries without access to the source code), these are completely different systems.

Yes, from offical version by RK
What is the kernel version and the link to the source code ?

So it seems that there is no solution to get LE FW that supports 4K hard decoding on RK3568, does not it?
Before receiving such support, main kernels - yes.
With the information in this forum, it looks like it is possible to solve the problem of supporting panfrost ， right?
