SYNOPSIS

struct vga_switcheroo_client {
struct pci_dev * pdev;
struct fb_info * fb_info;
enum vga_switcheroo_state pwr_state;
const struct vga_switcheroo_client_ops * ops;
enum vga_switcheroo_client_id id;
bool active;
bool driver_power_control;
struct list_head list;
};

MEMBERS

pdev

client pci device

fb_info

framebuffer to which console is remapped on switching

pwr_state

current power state

ops

client callbacks

id

client identifier. Determining the id requires the handler, so gpus are initially assigned VGA_SWITCHEROO_UNKNOWN_ID and later given their true id in vga_switcheroo_enable

active

whether the outputs are currently switched to this client

driver_power_control

whether power state is controlled by the driver's runtime pm. If true, writing ON and OFF to the vga_switcheroo debugfs interface is a no-op so as not to interfere with runtime pm

list

client list

DESCRIPTION

Registered client. A client can be either a GPU or an audio device on a GPU. For audio clients, the fb_info, active and driver_power_control members are bogus.
