Subject: [PATCH v2 0/3] Add descriptor definitions for a few new DSA operations
Date: Fri,  3 Mar 2023 13:34:10 -0800	[thread overview]
Message-ID: <20230303213413.3357431-1-fenghua.yu@intel.com> (raw)

A few new DSA operations are introduced [1]:
1. Memory fill with 16 bytes of pattern.
2. Translation fetch.
3. Data Integrity Extension (DIX) generate.

This series adds descriptor definitions for the new DSA operations.
With the definitions, user can issue the DSA operations to optimize
corresponding transactions.

Change log:
v2:
- Change anonymous struct to uint64_t for pattern_upper (Dave Jiang)
v1:
https://lore.kernel.org/dmaengine/20221108003944.2095567-1-fenghua.yu@intel.com/

Reference:
1. DSA 2.0 spec: https://software.intel.com/content/www/us/en/develop/articles/intel-data-streaming-accelerator-architecture-specification.html
