While working on a vga_switcheroo handler for Apple's Macbook Pros I stumbled upon a few bugs regarding the usage of nouveau with other switcheroo handlers and module unloading, here are my fixes for them. Andreas Heider (3): drm/nouveau: Initialize has_optimus drm/nouveau: Check dsm on switcheroo unregister drm/nouveau: Unregister switcheroo client on exit

Another vga_switcheroo cleanup. Maintainers, is it okay to include the one-line change of each driver in here or do you want that split into separate patches?

Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5. The main obstacle on these machines is that the panel mode in VBIOS is bogus. Fortunately gmux can switch DDC independently from the display, thereby allowing the inactive GPU to probe the panel's EDID. In short, vga_switcheroo and apple-gmux are amended with hooks to switch DDC, DRM core is amended with a

Hello all, this series includes a wide range of fixes - from a few month's old one-liners from Andreas Heider regarding vga_switcheroo, via a null pointer dereference and double memory allocation, to a buffer overflow.
