The default VGA device is a somewhat fluid concept on platforms with
|
|
|
bf91a40 |
multiple GPUs. Add support for setting it so switching code can update
|
|
|
bf91a40 |
things appropriately, and make sure that the sysfs code returns the right
|
|
|
bf91a40 |
device if it's changed.

vga-switcheroo currently changes the default VGA device by fiddling with
|
|
|
bf91a40 |
the IORESOURCE_ROM_SHADOW flag on the device. This isn't strictly accurate,
|
|
|
bf91a40 |
since there's no guarantee that switching also changes the ROM decoding.
|
|
|
bf91a40 |
Switch over to using the vgaarb functions for this.

fall back if nothing's set them.

EFI doesn't typically make use of the legacy VGA ROM, but it may still be
|
|
|
bf91a40 |
configured to pass that through to a given video device. This may lead to
|
|
|
bf91a40 |
an inaccurate choice of default video device. Add support to efifb to pick
|
|
|
bf91a40 |
out the correct active video device.
