Subject: [PATCH AUTOSEL 5.4 076/205] RDMA/hns: Bugfix for qpc/cqc timer configuration
Date: Thu, 16 Jan 2020 11:40:51 -0500
Message-ID: <20200116164300.6705-76-sashal@kernel.org> (raw)
In-Reply-To: <20200116164300.6705-1-sashal@kernel.org>

From: Yangyang Li <liyangyang20@huawei.com>

[ Upstream commit 887803db866a7a4e1817a3cb8a3eee4e9879fed2 ]

qpc/cqc timer entry size needs one page, but currently they are fixedly
configured to 4096, which is not appropriate in 64K page scenarios. So
they should be modified to PAGE_SIZE.

Fixes: 0e40dc2f70cd ("RDMA/hns: Add timer allocation support for hip08")
