Subject: [PATCH AUTOSEL 4.14 15/36] irqchip/gic-v3-its: Fix ITT_entry_size accessor
Date: Thu, 28 Feb 2019 10:13:16 -0500 [thread overview]
Message-ID: <20190228151337.12176-15-sashal@kernel.org> (raw)
In-Reply-To: <20190228151337.12176-1-sashal@kernel.org>
From: Zenghui Yu <yuzenghui@huawei.com>
[ Upstream commit 56841070ccc87b463ac037d2d1f2beb8e5e35f0c ]
According to ARM IHI 0069C (ID070116), we should use GITS_TYPER's
bits [7:4] as ITT_entry_size instead of [8:4]. Although this is
pretty annoying, it only results in a potential over-allocation
of memory, and nothing bad happens.
Fixes: 3dfa576bfb45 ("irqchip/gic-v3-its: Add probing for VLPI properties")
