Subject: [PATCH v2 1/7] bbdev: add FFT version member in driver info
Date: Thu, 21 Sep 2023 20:43:43 +0000 [thread overview]
Message-ID: <20230921204349.3285318-2-nicolas.chautru@intel.com> (raw)
In-Reply-To: <20230921204349.3285318-1-nicolas.chautru@intel.com>
This can be used to distinguish different version of the
flexible pointwise windowing applied to the FFT and expose
this platform configuration to the application.
The SRS processing chain
(https://doc.dpdk.org/guides/prog_guide/bbdev.html#bbdev-fft-operation)
includes a pointwise multiplication by time window whose degrees of
liberty cannot be exposed through a standard fixed API but through a hash
matching a version of such window definition (not HW IP specific)
defined as a long array of complex numbers.
Using that mechanism user application can retrieve information related
to what tables have been dynamically programmed on any bbdev device
supporting FFT windowing operation.
