Dvga_switcheroo.c2 * vga_switcheroo.c - Support for laptop with dual GPU using one set of outputs
33 #include <linux/apple-gmux.h>
71 * handler to control the power state of the discrete GPU, its ->switchto
72 * callback is a no-op for obvious reasons. The discrete GPU is often equipped
74 * register as a client so that vga_switcheroo can take care of the correct
77 * client (on the discrete GPU). The code is mostly prepared to support
81 * active client in vga_switcheroo parlance. The GPU not in use is the
82 * inactive client. When the inactive client's DRM driver is loaded,
86 * a client may alternatively request that the DDC lines are temporarily
93 * struct vga_switcheroo_client - registered client
