[RFC PATCH v1 0/1] mm: zswap - crypto acomp/scomp support
Hi Seth, Herbert, This series adds support for kernel's new crypto acomp/scomp compression & decompression framework to zswap. We verified these changes using the kernel's crypto deflate-scomp, lzo-scomp modules and Cavium's ThunderX ZIP driver (We will post the Cavium's ThunderX ZIP driver v2 patches with acomp/scomp support soon). Patch is on top of 'crypto-2.6' branch. please provide your comments.

[RFC PATCH v2 1/3] crypto: zip - Add ThunderX ZIP driver core
Add a driver for the ZIP engine found on Cavium ThunderX SOCs. The ZIP engine supports hardware accelerated compression and decompression. It includes 2 independent ZIP cores and supports: - DEFLATE compression and decompression (RFC 1951) - LZS compression and decompression (RFC 2395 and ANSI X3.241-1994) - ADLER32 and CRC32 checksums for ZLIB (RFC 1950) and GZIP (RFC 1952) The ZIP engine is presented as a PCI device. It supports DMA and scatter-gather.

[RFC PATCH v2 0/3] Cavium ThunderX ZIP driver
Hi Herbert, This series adds support for hardware accelerated compression & decompression as found on ThunderX (arm64) SOCs. As per your suggestion, we've switched to the new crypto acomp/scomp interface. To test the ZIP driver, we modified the kernel's ZSWAP to use acomp API's. Performance numbers from ZSWAP look promising. The "average time" for compressing a 4KB page: Compression Software: 278 usec Compression HW deflate : 17 usec Compression HW LZS : 11 usec Decompression Software : 20 usec Decompression HW deflate: 8 usec Decompression HW LZS: 6 usec Addressed the review comments from the RFC v1. - Added acomp/scomp crypto interface support. - Improved the error handling. - ZIP command completion codes are renamed suitably. - Removed some un-used code. - raw_smp_processor_id() replaced with smp_processor_id(). - Some more miscellaneous changes. Patches are on top of "kernel/git/herbert/crypto-2.6.git" repository Please provide your feedback.
