vga_switcheroo: Add the support for audio clients

2012-05-13T09:27:21+00:00

Add the support for audio clients to VGA-switcheroo for handling the
HDMI audio controller together with VGA switching.  The id of the
audio controller should be given explicitly at registration time
unlike the video controller.

vga_switcheroo: Introduce struct vga_switcheroo_client_ops

2012-05-13T09:24:09+00:00

This changes the API as a clean-up.  Instead of passing multiple
function pointers at each time, introduce a new struct holding the
whole callback functions and pass it to the registration.

The same struct will be used for the upcoming audio client
registration, too.

vga-switcheroo: Use vga_default_device()

2012-04-24T08:50:16+00:00

vga-switcheroo currently changes the default VGA device by fiddling with
the IORESOURCE_ROM_SHADOW flag on the device. This isn't strictly accurate,
since there's no guarantee that switching also changes the ROM decoding.
Switch over to using the vgaarb functions for this.

vgaarb: Add support for setting the default video device (v2)

2012-04-24T08:50:15+00:00

The default VGA device is a somewhat fluid concept on platforms with
multiple GPUs. Add support for setting it so switching code can update
things appropriately, and make sure that the sysfs code returns the right
device if it's changed.

v2: Updated to fix builds when __ARCH_HAS_VGA_DEFAULT_DEVICE is false.

drivers/gpu/vga/vgaarb.c: add missing kfree

2011-11-22T20:21:10+00:00

kbuf is a buffer that is local to this function, so all of the error paths
leaving the function should release it.

vgaarb: a NULL bridge is acceptable for root devices.

2011-11-14T10:03:15+00:00

I assumed all PCI buses had a bridge, but playing with qemu recently, I
discovered vgaarb bug where it wasn't detecting both devices shared a bridge
at the root level.

Don't check for NULL, if two buses have a NULL bridge, assume they share the
root bus.
