Right. And as I mentioned in the bug report,
The driver enables the Data Streaming Accelerator or DSA
capability for the 4th generation of the Intel Scalable Xeon
processor family, with code name Sapphire Rapids, and for future
Intel processors.
So, yes, it is relevant only for relatively recent x86_64 chips
produced by Intel (> 2019). For further details,
