Subject: [PATCH v3 02/12] baseband/acc: add FFT window width in the VRB PMD
Date: Fri, 29 Sep 2023 16:35:06 +0000 [thread overview]
Message-ID: <20230929163516.3636499-3-nicolas.chautru@intel.com> (raw)
In-Reply-To: <20230929163516.3636499-1-nicolas.chautru@intel.com>
This allows to expose the FFT window width being introduced in
previous commit based on what is configured dynamically on the
device platform.
