Thanks to Gonglei. v4 -> v5: - Fix potentially dereferencing uninitialized variables in 'virtio-crypto: use private buffer for control request'. Thanks to Dan Carpenter! v3 -> v4: - Don't create new file virtio_common.c, the new functions are added into virtio_crypto_core.c - Split the first patch into two parts: 1, change code style, 2, use private buffer instead of shared buffer - Remove relevant change. - Other minor changes. v2 -> v3: - Jason suggested that spliting the first patch into two part: 1, using private buffer 2, remove the busy polling Rework as Jason's suggestion, this makes the smaller change in each one and clear. v1 -> v2: - Use kfree instead of kfree_sensitive for insensitive buffer. - Several coding style fix. - Use memory from current node, instead of memory close to device - Add more message in commit, also explain why removing per-device request buffer. - Add necessary comment in code to explain why using kzalloc to allocate struct virtio_crypto_ctrl_request. v1: 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 (3): virtio-crypto: change code style virtio-crypto: use private buffer for control request virtio-crypto: wait ctrl queue instead of busy polling .../virtio/virtio_crypto_akcipher_algs.c | 95 ++++++------ drivers/crypto/virtio/virtio_crypto_common.h | 21 ++- drivers/crypto/virtio/virtio_crypto_core.c | 55 ++++++- .../virtio/virtio_crypto_skcipher_algs.c | 140 ++++++++---------- 4 files changed, 182 insertions(+), 129 deletions(-)
