Subject: [PATCH 4.19 53/64] iommu/amd: Fix the configuration of GCR3 table root pointer
Date: Wed, 22 Apr 2020 11:57:37 +0200 [thread overview]
Message-ID: <20200422095022.347731069@linuxfoundation.org> (raw)
In-Reply-To: <20200422095008.799686511@linuxfoundation.org>
From: Adrian Huang <ahuang12@lenovo.com>
[ Upstream commit c20f36534666e37858a14e591114d93cc1be0d34 ]
The SPA of the GCR3 table root pointer[51:31] masks 20 bits. However,
this requires 21 bits (Please see the AMD IOMMU specification).
This leads to the potential failure when the bit 51 of SPA of
the GCR3 table root pointer is 1'.
