[PATCH v2 31/32] powerpc/xive: Use XIVE domain under xmon and debugfs

Cédric Le Goater clg at kaod.org
Thu Jul 1 23:27:49 AEST 2021


The default domain of the PCI/MSIs is not the XIVE domain anymore. To
list the IRQ mappings under XMON and debugfs, query the IRQ data from
the low level XIVE domain.
