This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. This version is mostly identical to v2 but fixes an important issue: the drvdata must be set to the drm_device for sysfs to work, so the platform device structure now includes the

This series adds support for probing platform devices on Nouveau, as well as the DT bindings for GK20A. It doesn't enable the GPU yet on Tegra boards since a few extra things need to be supported before that. Thanks to the input received for v1, this version is more self-contained and shares less stuff between nouveau_drm and nouveau_platform. The major change is that nouveau_platform is now

This patch series is the final (?) step towards the initial support of GK20A, allowing it to be probed and used (currently at a very slow speed, and for offscreen rendering only) on the Jetson TK1 and Venice 2 boards. The main piece if the first patch which adds platform devices probing support to Nouveau. There are probably lots of things that need to be discussed about it, e.g.: * The way the

GP10B is the chip used in Tegra X2 SoCs. This patchset adds support for its base engines after reworking secboot a bit to accomodate its calling convention better. This patchset has been tested rendering simple off-screen buffers using Mesa and yielded the expected result. Alexandre Courbot (15): secboot: allow to boot multiple falcons secboot: pass instance to LS firmware loaders secboot:
