[PATCH] uadk: support appending tag for digest stream model
by Qi Tao 09 Jan '25

09 Jan '25

In common digest stream mode, io_bytes and iv_bytes need to be set to 0 when the final bd is calculated. Therefore, in the appending tag scenario, need to restore the values of io_bytes and iv_bytes to the values before they are set to 0. Therefore, the hardware can compute the overall hash value of the appending packet and the previously calculated packet, and reduce the repeated calculation.

[PATCH] uadk/v1 - add fair lock to replace CAS
by Qi Tao 27 Dec '24

27 Dec '24

From: Yang Shen <shenyang39(a)huawei.com> In Warpdrive sync mode, the driver writes a tag in the SQE to mark the owner and checks this tag when a request is completed. To ensure it functions properly, we added a lock to protect the receiving process. However, pthread_spin_lock is a CAS lock, which results in a situation where a thread can repeatedly acquire the lock while the completed request does not belong to it until timeout. Therefore, we introduce a fair lock to replace pthread_spin_lock. This way, every thread can acquire the lock in a round-robin manner.
