* gpu: nvgpu: reset patch_ctx.data_countSeema Khowala2017-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch buffer can hold 128 u32 entries. Each patch write takes total of 2 u32 entries, 1 u32 for addr and 1 u32 for data. Ideally 64 entries could be written before buffer overflows. Driver patch some things when creating the channel, and later when context switch type is changed after channel is loaded. Reset patch_ctx.data_count before beginning patch write otherwise system might not be in a state to accept all patch writes even if patch buffer has valid entries. If the patch buffer has non-zero entries, then the patch buffer would be read and all pri writes would be sent out. Once done, ucode updates the main header patch buffer count to 0.

* gpu: nvgpu: Convert VIDMEM work_struct to threadAlex Waterman2017-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert the work_struct used by the vidmem background clearing to a thread to make it more cross platform. The thread waits on a condition variable to determine when work needs to be done. The signal comes from the DMA API when it enqueues a new nvgpu_mem that needs clearing. Add logic for handling suspend: the CE cannot be accessed while the GPU is suspended. As such the background thread must be paused while the GPU is suspended and the CE is not available. Several other changes were also made: o Move the code that enqueues a nvgpu_mem from the DMA API code to a function in the VIDMEM code. o Move nvgpu_vidmem_get_pending_alloc() to the Linux specific code as this function is only used there. It's a trivial function that QNX can easily implement as well. o Remove the was_empty logic from the enqueue. Now just always signal the condition variable when anew nvgpu_mem comes in. o Move CE suspend to after MM suspend.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move most of the dma_buf usage present in the mm_gk20a.c code out to Linux specific code and some commom/mm code. There's two primary groups of code: 1. dma_buf priv field code (for holding comptag data) 2. Comptag usage that relies on dma_buf pointers For (1) the dma_buf code was simply moved to common/linux/dmabuf.c since most of this code is clearly Linux specific. The comptag code was a bit more complicated since there is two parts to the comptag code. Firstly there's the code that manages the comptag memory. This is essentially a simple allocator. This was moved to common/mm/comptags.c since it can be shared across all chips. The second set of code is moved to common/linux/comptags.c since it is the interface between dma_bufs and the comptag memory. Two other fixes were done as well: - Add struct gk20a to the comptag allocator init so that the proper nvgpu_vzalloc() function could be used. - Add necessary includes to common/linux/vm_priv.h.
