* 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>

* gpu: nvgpu: Use device instead of platform_deviceTerje Bergstrom2016-04-08
| | | | | | | | | Use struct device instead of struct platform_device wherever possible. This allows adding other bus types later. Change-Id: I1657287a68d85a542cdbdd8a00d1902c3d6e00ed Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1120466
