Hi Christian, Yes dma-buf is part of the picture, but rather if any work has been done to define an interface for the device itself, not the buffers.
I do know that these are mostly managed from user-space for performance reasons, however I was curious to see if anything has been in the works for kernel-space (kind of drm but for much more tailored for 2D blitters). -Ilyes On Tue, May 15, 2012 at 3:14 PM, Christian Robottom Reis <k...@linaro.org> wrote: > On Mon, May 14, 2012 at 10:18:17PM +0100, Ilyes Gouta wrote: >> I've previously read (probably on Phoronix) that Linaro is working out >> a 'standard' kernel interface for 2D blitters IPs as commonly found on >> SoCs. >> >> Has it ever been the case?
