* gpu: nvgpu: add missing busy calls for ctrl ioctlsKonsta Holtta2017-04-19
| | | | | | | | | | | | | | | | | | | | The following ioctls: - NVGPU_GPU_IOCTL_WAIT_FOR_PAUSE - NVGPU_GPU_IOCTL_RESUME_FROM_PAUSE - NVGPU_GPU_IOCTL_TRIGGER_SUSPEND - NVGPU_GPU_IOCTL_CLEAR_SM_ERRORS access hardware registers, so they should make sure that the gpu is powered on first. Add gk20a_{busy,idle}() pairs for them.

Then there's the function name which is is right justified and post-fixed with a line number. This keeps all statements lined up so long as the function name does not exceed the length of characters alloted for function names (33 currently). Lines are also left justified with 4 available spaces since there are currently no source files with over 9999 lines. The type of message (DBG, WRN, ERR) is then printed in brackets. Finally there's whatever message is to be printed. The new API will be largely the same except there will be an additional print of the GPU that the message has originated from in order to help debug cases where both an iGPU and dGPU are active. Also the implicit newline added in the legacy API has been removed. This is inline with essentially every other print function in the C world. There are numerous places where '\n' is added despite it not being needed which results in log files being littered with blank lines. This makes the logs much harder to read. Bug ...

This is done so that each GPU driver instance can accurately track how much memory it is using. In order to support this on older kernels a new NVGPU API has been made, nvgpu_kmem_cache_create(struct gk20a *g, size_t size) To handle the possibility that caches cannot be created with the same name. This patch also fixes numerous places where kfree() was wrongly used to free kmem_cache allocs.

* gpu: nvgpu: Add timeout APIAlex Waterman2016-12-05
Add a timeout API to nvgpu since this is a common operation done all across the nvgpu driver. Also add two new directories for this common code: drivers/gpu/nvgpu/common drivers/gpu/nvgpu/include/nvgpu The common directory is for common C code. The include directory is for common include files.
