* gpu: nvgpu: use vidmem by default in gmmu_alloc variantsKonsta Holtta2016-07-08
| | | | | | | | | | | | | | | | | | For devices that have vidmem available, use the vidmem allocator in gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem. Because all of the buffers haven't been tested to work in vidmem yet, rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at the end to declare explicitly that vidmem is used. Enabling vidmem for each now is a matter of removing "_sys" from the function call.

* gpu: nvgpu: add PRAMIN support for mem accessorsKonsta Holtta2016-05-24
| | | | | | | | | | | | | | | | | | | | To support vidmem, implement a way to access buffers via the PRAMIN window instead of just kernel-mapped sysmem buffers for iGPU as of now. Depending on the buffer aperture, choose between the two access types in the buffer memory accessor functions. vmap()/vunmap() pairs are no-ops for buffers that can't be cpu-mapped. Two uses of DMA_ATTR_READ_ONLY are removed in the ucode loading path to support writing to them too via the indirection in addition to cpu.

* gpu: nvgpu: refactor gk20a_mem_{wr,rd} for vidmemKonsta Holtta2016-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support vidmem, pass g and mem_desc to the buffer memory accessor functions. This allows the functions to select the memory access method based on the buffer aperture instead of using the cpu pointer directly (like until now). The selection and aperture support will be in another patch; this patch only refactors these accessors, but keeps the underlying functionality as-is. gk20a_mem_{rd,wr}32() work as previously; add also gk20a_mem_{rd,wr}() for byte-indexed accesses, gk20a_mem_{rd,wr}_n() for memcpy()-like functionality, and gk20a_memset() for filling buffers with a constant. The 8 and 16 bit accessor functions are removed. vmap()/vunmap() pairs are abstracted to gk20a_mem_{begin,end}() to support other types of mappings or conditions where mapping the buffer is unnecessary or different. Several function arguments that would access these buffers are also changed to take a mem_desc instead of a plain cpu pointer. Some relevant occasions are changed to use the accessor functions instead of cpu pointers without them (e.g., memcpying to and from), but the majority of direct accesses will be adjusted later, when the buffers are moved to support vidmem.

So while testing the nvgpu module using nvgpu_submit_twod test I found that it was never initialized. 2. Inside gk20a_init_gr_setup_sw, cleanup part calls for de-allocating the already allocated chunk of memory. Whereas, cleanup also gets called when memory allocation inside the same function fails. In such cases, we should have a non-null check else we attempt to free a non-allocated memory and kernel panics.

* gpu: nvgpu: New allocator for VA spaceAlex Waterman2015-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new buddy allocation scheme for the GPU's VA space. The bitmap allocator was using too much memory and is not a scaleable solution as the GPU's address space keeps getting bigger. The buddy allocation scheme is much more memory efficient when the majority of the address space is not allocated. The buddy allocator is not constrained by the notion of a split address space. The bitmap allocator could only manage either small pages or large pages but not both at the same time. Thus the bottom of the address space was for small pages, the top for large pages. Although, that split is not removed quite yet, the new allocator enables that to happen. The buddy allocator is also very scalable. It manages the relatively small comptag space to the enormous GPU VA space and everything in between. This is important since the GPU has lots of different sized spaces that need managing. Currently there are certain limitations. For one the allocator does not handle the fixed allocations from CUDA very well. It can do so but with certain caveats. The PTE page size is always set to small. This means the BA may place other small page allocations in the buddies around the fixed allocation. It does this to avoid having large and small page allocations in the same PDE.
