* gpu: nvgpu: remove SOF event generationThomas Fleury2016-05-21
| | | | | | | | | | | | | | | | | | | | | | | | FECS trace are currently collected using periodic polling every 16.66 ms. Whenever polling thread finds some events from FECS, it generates a SOF event with current PTIMER value. These events may introduce out of order timestamps, and extra processing would be required in driver to insert them in the right order. This change removes SOF event generation, as they is currently no use case for them.

| | | | | | | | | | | | | | | | | | | | | fecs_trace.disable() method kills polling thread and waits until it completes. dev->lock must not be held while calling this function, as polling thread may attempt to acquire it, leading to a deadlock.

* gpu: nvgpu: Read all fields of device_infoTerje Bergstrom2016-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | We were not using the engine_type field in device info, and the code did not handle chained entries properly. 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.
