Subject: [dpdk-dev] [PATCH] raw/ioat: fix missing ring pointer reset
Date: Thu, 17 Jun 2021 14:18:15 +0000 [thread overview]
Message-ID: <20210617141815.93367-1-kevin.laatz@intel.com> (raw)
In the event of a device reconfigure, "hdls_avail" is not being reset. This
can lead to miscalculations in rte_ioat_completed_ops(), causing the
function to report an incorrect amount of completed operations. This patch
fixes the issue by resetting "hdls_avail" during the device configure.
Fixes: 74464005a2af ("raw/ioat: rework SW ring layout")
Signed-off-by: Kevin Laatz <kevin.laatz@intel.com>
