From 0c271f90a07a02ae947c69efb45fd08bb3b5d583 Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Sat, 29 May 2021 07:03:22 +0000 Subject: [PATCH] Documentation: Generalize the "pci=noats" boot parameter maillist inclusion category: feature bugzilla: 51855 CVE: NA Reference: https://jpbrucker.net/git/linux/commit/?h=sva/2021-03-01&id=25fe4fbaddf2401ab711d800e89452f41930f98b --------------------------------------------- The "pci=noats" kernel parameter disables PCIe ATS globally, and affects any ATS-capable IOMMU driver. So rather than adding Arm SMMUv3, which recently gained ATS support, to the list of relevant build options, simplify the noats description.
