Enable LIMA driver support for MALI450 gpu

I have been working on MALI450 gpu lately with rk3328 SoC and using mali gpu kernel driver for that purpose but couldn’t render glmark2 using GPU.

After referring to forums I have found out that the opensource LIMA driver supports MALI450 gpu and can be used for this purpose. But the LIMA driver support is added from kernel version 5.1 or later while I am using vendor kernel 4.4.194 for rk3328.

Any idea how can I get LIMA support with this kernel version and get my GPU working?

I am using Yocto (ZEUS) build system with meta-radxa provided by Radxa only.

Thanks in advance.


Can anyone help here?
