From 1a2aefae6627170fdee689b394a65f76080c068a Mon Sep 17 00:00:00 2001 From: Artyom Tarasenko Date: Sun, 12 Jun 2016 22:19:43 +0200 Subject: [PATCH] target-sparc: on UA2005 don't deliver Interrupt_level_n IRQs in hypervisor mode As described in Chapter 5.7.6 of the UltraSPARC Architecture 2005, outstanding disrupting exceptions that are destined for privileged mode can only cause a trap when the virtual processor is in nonprivileged or privileged mode and PSTATE.ie = 1. At all other times, they are held pending.
