Current best practice is to configure and bind +at least one workqueue for each IAA device, but as long as there is at +least one workqueue configured and bound to any IAA device in the +system, the iaa_crypto driver will work, albeit most likely not as +efficiently. + +The IAA crypto algorigthms is operational and compression and ...

(IAA) for parallel compression of pages in large folios. 1) crypto acomp & iaa_crypto driver enablers for batching: Relevant. patches are tagged with "crypto:" in the subject: Patch 1) New acomp_alg/crypto_acomp batch_compress() and batch_decompress() interfaces, that swap modules can invoke using the new.

2025年3月3日 · With v8 of this patch series, the IAA compress batching feature will be enabled seamlessly on Intel platforms that have IAA by selecting 'deflate-iaa' as the zswap compressor, and using the iaa_crypto 'async' sync_mode driver attribute.

2023年5月8日 · From: Tom Zanussi <[email protected]> Hi, this is v4 of the IAA crypto driver, incorporating feedback from v3. v4 changes: - Added and used DRIVER_NAME_SIZE for wq driver_name. - Changed all spaces to tabs in CRYPTO_DEV_IAA_CRYPTO_STATS config menu. - Removed the private_data void * from wq and replaced with wq_confdev() instead, as suggested by Dave Jiang. - Added more Reviewed-by tags. v3 ...

The iaa compression/decompression algorithms in later patches need a way to retrieve an appropriate IAA workqueue depending on how close the associated IAA device is to the current cpu.

Define an in-kernel API for adding and removing compression modes, which can be used by kernel modules or other kernel code that implements IAA compression modes.

Will you consider using QPL/IAA as an independent compression algorithm instead of an accelerator? In this way, we can better utilize hardware performance and some features, such as IAA's canned mode, which can be dynamically generated by some statistics of data.

Re: [PATCH v5 13/15] crypto: iaa - Add support for default IAA 'canned' compression mode

For example, zswap can select the IAA fixed deflate algorithm 'deflate-iaa' via: # echo deflate-iaa > /sys/module/zswap/parameters/compressor This patch adds iaa_crypto as an idxd sub …
