Here are a few small fixes for issues we found while implementing support for GM20B. The first two are specific to Tegra/GK20A, but the last 3 patches may have a broader (hopefully beneficial) effect. Note that the newly introduced gf100_gr_wait_idle() function on patch 5/5 is exported on purpose. GK20A and GM20B drivers will soon make use of it. Ben, since you seemed to like these changes, a pull request follows in case you feel like playing! :) The following changes since commit 258eea3b7493a4e4e8831efbbb5d0a3e2b1a44aa: drm: Do not leak...

Second version of this patchset. Not many changes since first version - I hope this means the changes are not too controversial. Changes since v1: - Removed lookup for previous FW files in "nouveau/" - Went back to using request_firmware() since we only try to load one file Original cover letter follows: GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support

Hello everyone, GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support for it, based on a rework of the already-supported GK20A. It also introduces support for NVIDIA-provided firmware files, which is why I have added a few NVIDIA people who are relevant to this discussion. The first patch adds support for loading the FECS and GPCCS firmwares from firmware files
