Modernize vga_switcheroo by using a device link to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into, v2. Changes since v1: - Replace patch [1/7] to use pci_save_state() / pci_restore_state() for consistency between runtime PM code path of bound and unbound devices. (Rafael, Bjorn) - Patch [5/7]: Drop an unnecessary initialization. (Bjorn) Rephrase

Modernize vga_switcheroo by using a "device link" to enforce a runtime PM dependency from an HDA controller to the GPU it's integrated into. Remove thereby obsoleted code and fix a bunch of bugs. Device links were introduced in v4.10. Users might see a small power saving if the discrete GPU is in use and its HDA controller is not, because the HDA controller is now allowed to runtime

Hello everyone, GK20A is the Kepler-based GPU used in the upcoming Tegra K1 chips. The following patches perform architectural changes to Nouveau that are necessary to support non-PCI GPUs and add initial support for GK20A. Although the support is still very basic and more user-space changes will be needed to make the full graphics stack run on top of it, we were able to successfully open

Hi everyone, Here is the second batch of patches to add GK20A support to Nouveau. This time we are adding the actual chip support, and this series brings the driver to a point where a slightly-tweaked Mesa successfully runs shaders and renders triangles on GBM! Many thanks to Thierry Reding and the people on the #nouveau IRC channel for their help without which we would not have reached this
