If/when we use more registers, we can update driver to clear them on start.We know the registers we care about, we don't know the ones we don't.
It seems easier to clear registers we care about.We could save/restore the registers we care about.Shouldn't a reset be equivalent to power cycling?If we did this, driver would need to restore registers
such as BAR etc.
I'm talking about FLRing all cards, not just those you want to use.reset using FLR/PM is complex because of the need to save/restore
config space. Doing this on a crashing kernel sounds scary.
Not for FLR. Too late to reset on PA write.It's also too lateWhy? the FLR is triggered by the guest kernel, so all drivers will be
now: changing behaviour will break old drivers.
aware it was FLRed.
