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

From: Sui Jingfeng <suijingfeng at loongson.cn> Currently, the default VGA device selection is not perfect. Potential problems are: 1) This function is a no-op on non-x86 architectures. 2) It does not take the PCI Bar may get relocated into consideration. 3) It is not effective for the PCI device without a dedicated VRAM Bar. 4) It is device-agnostic, thus it has to waste the effort to

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

From: Sui Jingfeng <suijingfeng at loongson.cn> On a machine with multiple GPUs, a Linux user has no control over which one is primary at boot time. This series tries to solve above mentioned problem by introduced the ->be_primary() function stub. The specific device drivers can provide an implementation to hook up with this stub by calling the vga_client_register() function. Once the

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
