[PATCH 2/2] pnv/psi: Initialize the PSIHB interrupts to match hardware |
Date: |
Fri, 30 Jun 2023 16:42:42 +0200 |
On P9/P10, the PSIHB interrupts are initialized with a PQ state of
0b01, i.e. interrupts are disabled. However the real hardware
initializes them to 0b00 for the PSIHB. This patch updates it, in case
an hypervisor is in the mood of checking it.
