The VGIC distributor struct has a number of fields which are named
subopimally when needing to add more refined handling of level-triggered
interrupts.
We also never handled writes to the GICD_ISPENDRn and GICD_ICPENDRn
properly, which was never a real concern until we started playing with
IRQ injection for assigned devices, IRQFDs, and other fun stuff.
This RFC series tries to address some of these issues.
*** WARNING ***
This series is untested!!
I am only sending it out now, untested, as is, giving people
ever-lasting right to ridicule me, because Eric Auger is blocked on this
work and I wanted to communicate my thoughts on how to handle this.
It also has the added benefit of receiving early comments (yes, please!)
and let other people who are messing around with this file a chance to
scream at me.
