Subject: [dpdk-stable] [PATCH v2 01/18] net/mlx5/windows: fix miss callback register for mem event
Date: Thu, 7 Oct 2021 01:03:33 +0300
Message-ID: <20211006220350.2357487-2-michaelba@nvidia.com> (raw)
In-Reply-To: <20211006220350.2357487-1-michaelba@nvidia.com>

From: Michael Baum <michaelba@oss.nvidia.com>

In device initialization, the driver registers to free hugepages events.
When husepage is released, this callback frees all its related MRs.

In Windows initialization, this callback is not registered what may
cause to use invalid memory.

This patch adds memory event callback registration in Windows
initialization.

Fixes: 980826dc6f0f ("net/mlx5: probe on Windows")
