* gpu: nvgpu: APIs to dump GR statusDeepak Nibade2015-04-04
| | | | | | | | | | | | | | | | | | Add below APIs to dump various GR status registers 1. debugfs : /d/gpu.0/gr_status Read this debugfs at runtime to get status registers 2. API gk20a_gr_debug_dump() Add this API in code to dump registers at any point Bug 200062436 Change-Id: Ic1115b5a2fc16362954b5ed8a9e70afb872a8d91 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/486465 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: Add NULL pointer check to debug codeArto Merilainen2015-03-18
| | | | | | | | | | | | | | | nvgpu exposes debug dump functionality. Currently this function misses NULL pointer checks and therefore in cases where the driver is compiled but the device is disabled, the driver crashes kernel. This patch adds the missing NULL pointer check.

* gpu: nvgpu: add __must_check to gk20a_busyKonsta Holtta2015-03-18
| | | | | | | | | | | | | | | The return value of gk20a_busy must be checked since it may not succeed in some cases. Add the __must_check attribute that generates a compiler warning for code that does not read the return value and fix all uses of the function to take error cases into account.

* 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.

* Revert "gpu: nvgpu: Dump offending push buffer fragment"Arto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | | | Channel and gpfifo allocations are entirely separated from each other, however, the code here assumes that active channel means that the channel also has a gpfifo. This reverts commit a24602f094380539788696d1b1567a4f4d914b17 which added gpfifo dump. Changing debug dumping to be safe requires refactoring the channel release code to use proper locking.

| | | | | | | | | | | | | | When outputting debug dump, print the contents of current push buffer segment. Also changes the debug dump to use pr_cont when applicable, and dumps state before recovering in case channel was not loaded to an engine.

| | | | | | | | | | | | | | | Currently the gpu driver assumes that the GPU is a child of host1x. This is an invalid assumption and therefore we need to get the host1x device from device tree based on nvidia,host1x property.
