From dmesg.boot:

...

panfrost0: info: clock rate = 500000000
panfrost0: info: mali-t860 id 0x860 major 0x2 minor 0x0 status 0x0

There is one function in the linux compat layer that is still a stub
that needs to be written to allocate space for the MMU page table.

It will probably have the same problem as the lima driver when trying to
load shaders from userland, but it provides another platform to use to
debug this.

Then it needs to be made to build as a module as the source is GPL.

Maybe need to decide what to do about MesaLib in userland, is it worth
committing the Makefile changes to build lima and panfrost before the
branch for NetBSD-10? There are no source changes needed to MesaLib, one
small change to libdrm.
