Originally both SW and HW crypto PMDs use rte_crypot_op based API to process the crypto workload asynchronously. This way provides uniformity to both PMD types, but also introduce unnecessary performance penalty to SW PMDs that have to "simulate" HW async behavior (crypto-ops enqueue/dequeue, HW addresses computations, storing/dereferencing user provided data (mbuf) for each crypto-op, etc).
The aim is to introduce a new optional API for SW crypto-devices to perform crypto processing in a synchronous manner. v3 to v4 changes: - add feature discovery in the ipsec example application when using cpu-crypto - add gmac in aesni-gcm - add tests for aesni-gcm/cpu crypto mode - add documentation: pg and rel notes - remove xform flags as no longer needed - add some extra API comments - remove compilation error from v3 Marcin Smoczynski (8): cryptodev: introduce cpu crypto support API crypto/aesni_gcm: cpu crypto support test/crypto: add CPU crypto tests security: add cpu crypto action type ipsec: introduce support for cpu crypto mode examples/ipsec-secgw: cpu crypto support examples/ipsec-secgw: cpu crypto testing doc: add cpu crypto related documentation app/test/Makefile | 1 + app/test/cpu_crypto_all_gcm_perf_test_cases.h | 11 + app/test/cpu_crypto_all_gcm_unit_test_cases.h | 49 + .../cpu_crypto_all_gmac_unit_test_cases.h | 7 + app/test/meson.build | 1 + app/test/test_cryptodev_cpu_crypto.c | 930 ++++++++++++++++++ doc/guides/cryptodevs/aesni_gcm.rst | 5 + doc/guides/prog_guide/cryptodev_lib.rst | 31 + doc/guides/prog_guide/ipsec_lib.rst | 8 + doc/guides/prog_guide/rte_security.rst | 15 +- doc/guides/rel_notes/release_20_02.rst | 8 + drivers/crypto/aesni_gcm/aesni_gcm_ops.h | 9 + drivers/crypto/aesni_gcm/aesni_gcm_pmd.c | 220 ++++- drivers/crypto/aesni_gcm/aesni_gcm_pmd_ops.c | 3 + .../crypto/aesni_gcm/aesni_gcm_pmd_private.h | 11 +- examples/ipsec-secgw/ipsec.c | 23 +- examples/ipsec-secgw/ipsec_process.c | 134 ++- examples/ipsec-secgw/sa.c | 28 +- examples/ipsec-secgw/test/common_defs.sh | 21 + examples/ipsec-secgw/test/linux_test4.sh | 11 +- examples/ipsec-secgw/test/linux_test6.sh | 11 +- .../test/trs_3descbc_sha1_common_defs.sh | 8 +- .../test/trs_aescbc_sha1_common_defs.sh | 8 +- .../test/trs_aesctr_sha1_common_defs.sh | 8 +- .../test/tun_3descbc_sha1_common_defs.sh | 8 +- .../test/tun_aescbc_sha1_common_defs.sh | 8 +- .../test/tun_aesctr_sha1_common_defs.sh | 8 +- lib/librte_cryptodev/rte_crypto_sym.h | 61 ++ lib/librte_cryptodev/rte_cryptodev.c | 33 + lib/librte_cryptodev/rte_cryptodev.h | 20 + lib/librte_cryptodev/rte_cryptodev_pmd.h | 19 + .../rte_cryptodev_version.map | 1 + lib/librte_ipsec/esp_inb.c | 154 ++- lib/librte_ipsec/esp_outb.c | 134 ++- lib/librte_ipsec/misc.h | 118 +++ lib/librte_ipsec/rte_ipsec.h | 18 +- lib/librte_ipsec/sa.c | 112 ++- lib/librte_ipsec/sa.h | 17 + lib/librte_ipsec/ses.c | 3 +- lib/librte_security/rte_security.h | 6 +- 40 files changed, 2119 insertions(+), 162 deletions(-) create mode 100644 app/test/cpu_crypto_all_gcm_perf_test_cases.h create mode 100644 app/test/cpu_crypto_all_gcm_unit_test_cases.h create mode 100644 app/test/cpu_crypto_all_gmac_unit_test_cases.h create mode 100644 app/test/test_cryptodev_cpu_crypto.c -- 2.17.1
