[PATCH v2 11/20] ppc/xive2: Add support for notification injection on ESB pages |
Date: |
Thu, 2 Sep 2021 15:09:19 +0200 |
This is an internal offset used to inject triggers when the PQ state
bits are not controlled locally. Such as for LSIs when the PHB5 are
using the Address-Based Interrupt Trigger mode and on the END.
