* gpu: nvgpu: cde: set err properly in oom conditionKonsta Holtta2015-03-18
| | | | | | | | | | | | When gk20a_gmmu_map runs out of memory, set the error code before returning early, so that caller knows about that cde load didn't succeed and wouldn't use the bad context.

| | | | | | | | | | | | | | | | | -Change cde_buf to use writecombined cpu mapping. -Since reading writecombined cpu data is still slow, avoid reads in gk20a_replace_data by checking whether a patch overwrites a whole word. -Remove unused distinction between src and dst buffers in cde_convert. -Remove cde debug dump code as it causes a perf hit.

* gpu: nvgpu: rename gpu ioctls and structs to nvgpuKonsta Holtta2015-03-18
| | | | | | | | | | | | | | To help remove the nvhost dependency from nvgpu, rename ioctl defines and structures used by nvgpu such that nvhost is replaced by nvgpu. Duplicate some structures as needed. Update header guards and such accordingly.

* gpu: nvgpu: cde: CDE swizzling optimizationsJussi Rasanen2015-03-18
| | | | | | | | | | | | | | | | | Change CDE swizzling shader kernel size to 8x8 to avoid waste with relatively small surfaces. Map compbit backing store and destination surface as cacheable. Clean up kernel size calculation.

Actually store the color in kernel so that the feature works.

| | | | | | | | | | | | | | | | | | | | Defer CDE app initialization to the point where we actually need to launch the app. This allows us to use the compression state API also on T124 where we never use the CDE app. Also return the error code correctly from gk20a_prepare_compressible_read.

| | | | | | | | | 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.
