* 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.

* gpu: nvgpu: fix allocation and map size mismatch while mappingDeepak Nibade2016-09-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to allocate larger size than user requested e.g. If we allocate at 64k granularity, and user asks for 32k buffer, we end up allocating 64k chunk. User still asks to map the buffer with size 32k and hence we reserve mapping addresses only for 32k But due to bug in mapping in update_gmmu_ptes_locked() we end up creating mappings considering size of 64k and corrupt some mappings Fix this by considering min(chunk->length, map_size) while mapping address range for a chunk Also, map_size will be zero once we map all requested address range.

* gpu: nvgpu: improve sync create/destroy logicSachit Kadle2016-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change improves the aggressive sync creation & destruction logic to avoid lock contention in the submit path. It does the following: 1) Removes the global sync destruction (channel) threshold, and adds a per-platform parameter. 2) Avoids lock contention in the clean-up/submit path when aggressive sync destruction is disabled. 3) Creates sync object at gpfifo allocation time (as long as we are not in aggressive sync destroy mode), to enable faster first submits Bug 1795076 Change-Id: Ifdb680100b08d00f37338063355bb2123ceb1b9f Signed-off-by: Sachit Kadle <skadle@nvidia.com> Reviewed-on: http://git-master/r/1202425 (cherry picked from commit ac0978711943a59c6f28c98c76b10759e0bff610) Reviewed-on: http://git-master/r/1202427 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
