[PATCH v2 31/32] powerpc/xive: Use XIVE domain under xmon and debugfs
From: Cédric Le Goater <clg@kaod.org>
Date: 2021-07-01 13:38:18
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
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.
