What is the API that a user space apps will use to control the state of
VGA devices?

For example:
1) a standard device exposing IOCTLs needing an header file describing
it.
or 2) Building a new tree in /sys/class/vga that uses attributes to
control the state. you turn the device on by copying a '1' to the
attribute.

Once we pick sysfs or ioctl API, what should the full set of calls look
like?

I know internally how to find the VGA cards using the PCI class. I
meant this in the context of how do you enumerate all of the VGA
devices in a domain from a user space app. What is the API for

this?

I don't follow the logic behind the question. Once you have the vga
locking device then that needs to handle the vga on/off.
