Subject: [PATCH AUTOSEL 4.14 10/35] amd/iommu: Fix Guest Virtual APIC Log Tail Address Register
Date: Thu, 29 Nov 2018 01:00:44 -0500 [thread overview]
Message-ID: <20181129060110.159878-10-sashal@kernel.org> (raw)
In-Reply-To: <20181129060110.159878-1-sashal@kernel.org>
From: Filippo Sironi <sironi@amazon.de>
[ Upstream commit ab99be4683d9db33b100497d463274ebd23bd67e ]
This register should have been programmed with the physical address
of the memory location containing the shadow tail pointer for
the guest virtual APIC log instead of the base address.
Fixes: 8bda0cfbdc1a ('iommu/amd: Detect and initialize guest vAPIC log')
