Subject: [PATCH 5.9 37/46] net/mlx5: Fix wrong address reclaim when command interface is down
Date: Sun, 6 Dec 2020 12:17:45 +0100 [thread overview]
Message-ID: <20201206111558.245562509@linuxfoundation.org> (raw)
In-Reply-To: <20201206111556.455533723@linuxfoundation.org>
From: Eran Ben Elisha <eranbe@nvidia.com>
[ Upstream commit 1d2bb5ad89f47d8ce8aedc70ef85059ab3870292 ]
When command interface is down, driver to reclaim all 4K page chucks that
were hold by the Firmeware. Fix a bug for 64K page size systems, where
driver repeatedly released only the first chunk of the page.
Define helper function to fill 4K chunks for a given Firmware pages.
Iterate over all unreleased Firmware pages and call the hepler per each.
Fixes: 5adff6a08862 ("net/mlx5: Fix incorrect page count when in internal error")
