This particular device type is untested though, so I'd be interested in hearing results on way or another. There shouldn't be any problem using multiple qat(4) instances, though this was not tested either. In OpenCrypto's model each session is bound to a specific device and new sessions are bound to the device with fewest sessions, so if you have at least two crypto sessions active in your workload both QAT devices will be used, for better or worse. > On Mon, Nov 9, 2020 at 9:53 PM Mark Johnston <markj@freebsd.org> wrote: > > > On Mon, Nov 09, 2020 at 09:44:40PM +0300, Özkan KIRIK wrote: > > > great job! thank you! > > > > > > Does the work supports Xeon D-2100 series ?
