dnbd3.git/src/shared/crc32.c, branch isfant Distributed Network Block Device 3 --rewrite for Kernel 3.x https://git.openslx.org/dnbd3.git/atom/src/shared/crc32.c?h=isfant 2020-10-16T15:15:49+00:00 [BUILD] rewrite CMake build system to track changes of source files 2020-10-16T15:15:49+00:00 Manuel Bentele 2020-10-16T15:15:49+00:00 urn:sha1:969496f15e1e0359e26c2c6e995ad4ef82720f86 This change restructures the source code directories, separates shared form non-shared application code and adds CMake dependencies. These dependencies allow the tracking of changes and trigger a rebuild of those build targets where changed files are involved. WARNING: Note that the support of the DNBD3_SERVER_AFL build option is not supported yet. Thus, the option should be never turned on. [SHARED] crc32: Don't skip table lookup if PCLMUL is unavailable 2020-03-19T20:45:12+00:00 Simon Rettberg 2020-03-19T20:45:12+00:00 urn:sha1:be628c705594a36f6aa649613ddf6c86039192a1 [SERVER] crc32: Fix compile with optimizations 2020-03-19T20:15:42+00:00 Simon Rettberg 2020-03-19T20:15:42+00:00 urn:sha1:0f47d29912b0e3d0e387db715a16b7b4f273f389 Should have tested in "Release" mode I guess. Seems we're at about 24x performance this way, so hooray. [SERVER] Use PCLMUL for crc32 on AMD64 if available 2020-03-19T19:43:15+00:00 Simon Rettberg 2020-03-19T19:43:15+00:00 urn:sha1:3d2f1f605e07b511c4ebf79c936c7061dd918957 This is about 16x as fast as before with the lookup table for processing 4 bytes at a time and should work on any AMD64 CPU made in the last decade. We still need an AltiVec implementation for G5 though. [SERVER] Get rid of zlib dependency 2017-10-24T12:19:53+00:00 Simon Rettberg 2017-10-24T12:19:53+00:00 urn:sha1:3bf0f5cfbe96b8aa8681f8fb26868188b52ec8e8 We only used it for CRC-32, so now the source tree includes a stripped down version of the crc32 code from the zlib project.
