| H A D | arm-gic-v4.h | 64edfaa9 Tue Dec 24 05:10:29 CST 2019 Marc Zyngier <maz@kernel.org> irqchip/gic-v4.1: Implement the v4.1 flavour of VMAPP
The ITS VMAPP command gains some new fields with GICv4.1:
- a default doorbell, which allows a single doorbell to be used for
all the VLPIs routed to a given VPE
- a pointer to the configuration table (instead of having it in a register
that gets context switched)
- a flag indicating whether this is the first map or the last unmap for
this particular VPE
- a flag indicating whether the pending table is known to be zeroed, or not
Plumb in the new fields in the VMAPP builder, and add the map/unmap
refcounting so that the ITS can do the right thing.
