If the GIC has the security extension support enabled, then a non-secure access to ICC_PMR must take account of the non-secure view of interrupt priorities, where real priorities 0x00..0x7f are secure-only and not visible to the non-secure guest, and priorities 0x80..0xff are shown to the guest as if they were 0x00..0xff. We had the logic here wrong: * on reads, the priority is in the secure range if bit 7 is clear, not if it is set * on writes, we want to set bit 7, not mask everything else Our ICC_RPR read code had the same error as ICC_PMR. (Compare the GICv3 spec pseudocode functions ICC_RPR_EL1 and ICC_PMR_EL1.)
