From e8d2d82d4a73f37b3270e4fd19ba83e48b589656 Mon Sep 17 00:00:00 2001 From: Jay Cornwall Date: Wed, 26 Feb 2014 15:49:31 -0600 Subject: [PATCH] iommu/amd: Fix PASID format in INVALIDATE_IOTLB_PAGES command This patch corrects the PASID format in the INVALIDATE_IOTLB_PAGES command, which was caused by incorrect information in the AMD IOMMU Architectural Specification v2.01 document. Incorrect format: cmd->data[0][16:23] = PASID[7:0] cmd->data[1][16:27] = PASID[19:8] Correct format: cmd->data[0][16:23] = PASID[15:8] cmd->data[1][16:23] = PASID[7:0] However, this does not affect the IOMMUv2 hardware implementation, and has been corrected since version 2.02 of the specification (available through AMD NDA).
