* gpu: nvgpu: cde: Map backing store as read-onlyLauri Peltonen2015-03-18
| | | | | | | | | The cde shader will only read data from the global compbit backing store. Map it as read-only to enforce this. Change-Id: If5be44b8daedd5e7fdee650a6e76befa7bdecfd6 Signed-off-by: Lauri Peltonen <lpeltonen@nvidia.com> Reviewed-on: http://git-master/r/486679
* gpu: nvgpu: cde: Re-use contextArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | Currently cde reinitialises the context each time before submitting work to the channel. This was done to ensure that we are able to get clean context for the shader during development phase. However, as the shader has been tested to work w/o reinitialising the context, we can remove the reinitialisation to gain better performance.

* gpu: nvgpu: cde: Allow large surfacesArto Merilainen2015-03-18
| | | | | | | | | | | | | Currently cde swizzling application forces upper limit to surface size. The limitation is artificial (i.e. nothing prevents shader handling larger surfaces). Therefore, make the error condition a warning.
