So do these drivers provide registers etc ? How much extra effort is required to get 2d accel with a clean room userland driver ? If we can do that and also get rasterisers working we can have a fully functional gnu/linux desktop futureproofed with wayland support. Also could we reuse that multimedia decoding engine from the a20 ? On May 8, 2017 12:13 PM, "Luke Kenneth Casson Leighton" lkcl@lkcl.net wrote:

everything. the open source kernel "driver" cannot actually be called a "driver" at all. it is nothing more than a gateway to the actual hardware. peripherals on ARM are memory-mapped: the "driver" simply provides access to the shared memory region (plus maybe handles some interrupts).
this is a constant source of confusion with people believing that just because the "shim" has been released, somehow magically it's all okay.
