From 895fe9bb3f8ed664d5dbdc8190013eebfaf144a7 Mon Sep 17 00:00:00 2001 From: Fenghua Yu Date: Wed, 28 Aug 2024 16:34:00 -0700 Subject: [PATCH] dmaengine: idxd: Add a new DSA device ID for Granite Rapids-D platform commit f91f2a9879cc77db1f45f690f38f42698580416e upstream. A new DSA device ID, 0x11fb, is introduced for the Granite Rapids-D platform. Add the device ID to the IDXD driver. Since a potential security issue has been fixed on the new device, it's secure to assign the device to virtual machines, and therefore, the new device ID will not be added to the VFIO denylist. Additionally, the new device ID may be useful in identifying and addressing any other potential issues with this specific device in the future. The same is also applied to any other new DSA/IAA devices with new device IDs. Intel-SIG: commit f91f2a9879cc7 dmaengine: idxd: Add a new DSA device ID for Granite Rapids-D platform Add GNR new idxd id support.
