Date: Tue, 15 Sep 2015 08:45:44 -0400 From: Stephane Viau <sviau@...eaurora.org> To: dri-devel@...ts.freedesktop.org Cc: linux-arm-msm@...r.kernel.org, linux-kernel@...r.kernel.org, robdclark@...il.com, Stephane Viau <sviau@...eaurora.org> Subject: [PATCH] rnndb: Add Pixel Extension registers Pixel Extension are extra pixels fed to the QSEED2 scalar; this information is needed to produce an output image. These values depend on various parameters, such as scalar type, initial phase, phase step, etc. Pixel extension values used to be handled and calculated by hardware; however, software could also overwrite those values for optimization. In some hardware (eg: MDP5 v1.7), software *must* program those values since they are not handled in hardware.
