Add a new vga-switcheroo client callback to allow clients to register
for receiving notifications when a mux switch is pending, completed,
or failed. This allows individual client drivers to prepare for or
respond to mux switches to and from the registered client device.
Signed-off-by: Daniel Dada
vga-switcheroo supports the following types of mux switch events:
* standard: checks the clients' can_switch() callbacks and switches
the mux if the client drivers report that they are prepared for a
switch. Also uses client and handler callbacks to manage power on
the GPUs and reprobe displ
Attempting to commit a modeset while mux-switched away can cause
problems due to DisplayPort links being unavailable while they are
physically disconnected. In order to avoid this, bail out of atomic
commit early if attempted while a display mux is switched away.
Signed-off-by: Daniel Dadap

vga-switcheroo clients may wish to know whether they are currently
active, i.e., whether the mux is currently switched to the client
in question. Add an in-kernel API to test whether a vga-switcheroo
client, as identified by PCI device, is actively switched.

It is not possible to train a Displayport link while the lanes are
physically disconnected by a display mux. In order to prevent problems
associated with attempting to train a disconnected link, abort eDP
link training if the i915 GPU is not an active vga-switcheroo client.
This short circuit is eD
Add a vga-switcheroo callback for reprobing displays. Use this new
callback to retrain the link on all DP encoders after a mux switch.

Changes to allow vga-switcheroo to switch the mux while modesetting
clients remain active. There is existing support for switching the
mux without checking can_switch; however, this support also does not
reprobe after the mux switch is complete. This patch series adds a new
