Hi, The main point of this series is to improve the performance for virtio crypto: - Use wait mechanism instead of busy polling for ctrl queue, this reduces CPU and lock racing, it's possiable to create/destroy session parallelly, QPS increases from ~40K/s to ~200K/s. - Enable retry on crypto engine to improve performance for data queue, this allows the larger depth instead of 1. - Fix dst data length in akcipher service. - Other style fix. lei he (2): virtio-crypto: adjust dst_len at ops callback virtio-crypto: enable retry for virtio-crypto-dev zhenwei pi (2): virtio-crypto: wait ctrl queue instead of busy polling virtio-crypto: move helpers into virtio_crypto_common.c drivers/crypto/virtio/Makefile | 1 + .../virtio/virtio_crypto_akcipher_algs.c | 92 ++++++------ drivers/crypto/virtio/virtio_crypto_common.c | 92 ++++++++++++ drivers/crypto/virtio/virtio_crypto_common.h | 25 +++- drivers/crypto/virtio/virtio_crypto_core.c | 37 +---- .../virtio/virtio_crypto_skcipher_algs.c | 134 ++++++++---------- 6 files changed, 222 insertions(+), 159 deletions(-) create mode 100644 drivers/crypto/virtio/virtio_crypto_common.c -- 2.20.1 _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
