| H A D | vas.c | c20e1e29 Thu Apr 16 01:00:06 CDT 2020 Haren Myneni <haren@linux.ibm.com> powerpc/vas: Alloc and setup IRQ and trigger port address
Allocate a xive irq on each chip with a vas instance. The NX coprocessor
raises a host CPU interrupt via vas if it encounters page fault on user
space request buffer. Subsequent patches register the trigger port with
the NX coprocessor, and create a vas fault handler for this interrupt
mapping.
