* gpu: nvgpu: Allow disabling CDE functionalityTerje Bergstrom2018-02-15
| | | | | | | | | | | | | CDE is a Tegra SoC specific feature. Add new config option CONFIG_NVGPU_SUPPORT_CDE and #ifdef all CDE specific code with it. JIRA NVGPU-4 Change-Id: I6f0b0047d6ba2b5c36c2eb9b8a1514776741f5b5 Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1648002 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: Use TSG for CDE channelsTerje Bergstrom2017-12-13
| | | | | | | | | | | | | | All channels should be wrapped in TSGs so that bare channel support can be dropped. Bind all CDE channels to TSGs.

* gpu: nvgpu: don't run cde shader for 0 ctaglinesKonsta Holtta2017-11-22
| | | | | | | | | | | | | | | If the associated buffer is not compressed, it would be invalid to call the cde swizzler shader with zero lines. The fences in PREPARE_COMPRESSIBLE_READ still need to be managed, so just do a dummy submit with zero entries when lines is zero for the buffer.

* gpu: nvgpu: Fix missing #includes and fw decls in Linux codeTerje Bergstrom2017-11-06
| | | | | | | | | | | | | ioctl_channel.h and cde.h referred to multiple structures that were not forward declared or explitly #included in. Add several forward declarations and #includes. Also add #include for <uapi/linux/nvgpu.h> to multiple Linux .c files that were missing it.

* gpu: nvgpu: Move CDE code to Linux moduleTerje Bergstrom2017-09-11
CDE is only used in Linux platforms, and the code is highly dependent on Linux APIs. Move the common CDE code to Linux module and leave only the chip specific parts to HAL.
