From 61cc78be359d1f0031f65c0e94152d744f1ebec4 Mon Sep 17 00:00:00 2001 From: Tanmay Shah Date: Fri, 27 Oct 2023 23:53:59 +0530 Subject: [PATCH] soc: xilinx: fix unhandled SGI warning message [ Upstream commit 9c6724abf969251af53cdae525ad8100ec78d3c2 ] Xen broadcasts SGI to each VM when multiple VMs run on Xen hypervisor. In such case spurious SGI is expected if one event is registered by one VM and not registered by another VM. We let users know that Unhandled SGI is not error and expected if kernel is running on Xen hypervisor.
