From 195b79a97e6721ba8830036f47d2454545f32e44 Mon Sep 17 00:00:00 2001 From: Igor Druzhinin Date: Tue, 26 Nov 2019 17:08:19 +0000 Subject: [PATCH] AMD/IOMMU: honour IR setting while pre-filling DTEs IV bit shouldn't be set in DTE if interrupt remapping is not enabled. It's a regression in behavior of "iommu=no-intremap" option which otherwise would keep interrupt requests untranslated for all of the devices in the system regardless of wether it's described as valid in IVRS or not.
