* gpu: nvgpu: fix zcull programmingSeema Khowala2016-10-14
| | | | | | | | | | | | | | | | | | There are eight tiles per map tile register and depending on how many tpcs are present, there is a chance that s/w will be accessing un-allocated memory for reading tile values from temp buffers.

* gpu: nvgpu: Suppress error msg from VBIOS overlayTerje Bergstrom2016-10-09
| | | | | | | | | | | | | | | | | | | | Suppress error message when nvgpu tries to load VBIOS overlay, but one is not found. This situation is normal. This is done by moving gk20a_request_firmware() to be nvgpu generic function nvgpu_request_firmware(), and adding a NO_WARN flag to it. Introduce also a NO_SOC flag to suppress attempt to load firmware from SoC specific directory in addition to the chip specific directory. Use it for dGPU firmware files.

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.

The code assumed that first entry is for graphics and second for CE, which is not always true. Improve the code to go through all entries of device_info, and preserve values across entries until we reach the last entry. Only last entry triggers a write to fifo engine info. There can also be multiple engines with same type, so accumulate interrupts and reset ids from all of them. As the code got fixed, now it reads the engine enum correctly from hardware. We used to compare that against CE0, but we should compare against CE2. gk20a_fifo_reset_engine() uses wrong constants - it is passed a internal numbering of engines, but it compares them against hardware engine enum.

* 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.
