Subject: [dpdk-stable] patch 'net/bnx2x: fix build with GCC 11' has been queued to stable release 19.11.9
Date: Thu, 10 Jun 2021 14:06:12 +0200
Message-ID: <20210610120641.885862-24-christian.ehrhardt@canonical.com> (raw)
In-Reply-To: <20210610120641.885862-1-christian.ehrhardt@canonical.com>

Hi,

FYI, your patch has been queued to stable release 19.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/12/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/aecd308c092378ae627a795f9e8c3e65595d4384

Thanks.

Christian Ehrhardt <christian.ehrhardt@canonical.com>

Subject: [PATCH] net/bnx2x: fix build with GCC 11
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit b3c740e03751215ab01841975b8f5764023f953b ]

Reproduced with '--buildtype=debugoptimized' config,
compiler version: gcc (GCC) 12.0.0 20210509 (experimental)

Build error:
In file included from ../drivers/net/bnx2x/bnx2x_rxtx.c:8:
../drivers/net/bnx2x/bnx2x_rxtx.c: In function ‘bnx2x_upd_rx_prod_fast’:

REG_WR32 requires 'uint32_t', use union instead of cast to 'uint32_t'.

Bugzilla ID: 692
Fixes: 38dff79ba736 ("net/bnx2x: update HSI")
