1.22 会议 follow up
by Zhangfei Gao 23 Jan '25

1. longfang 问的ctx的问题 adapter 方案 ctx 是在worker 内部的，每个worker有pool, ctx 等资源，完全解耦/不相关的比如sve 是支持异步的， hw+sve 异步是完全没问题的，代码 wd_cipher_init2_ for (i = 0; i < adapter->workers_nb; i++) { // 依次初始化各worker wd_alg_attrs_init(worker, &wd_cipher_init_attrs); switch (driver_type) { case UADK_ALG_SVE_INSTR: 分配sve的ctxs // sve, ce 其实可以合并 case UADK_ALG_HW: 分配hw的ctx wd_cipher_common_init -> wd_init_async_request_pool(&worker->pool, // 分配worker自己的pool } 另外，adapter方案的调度是选择worker, 是以worker为调度单元比如小包 sw，大包 hw，我们之前的调度，是期望每次过来能选择不同的ctx，实际中多线程需要加锁，性能跟不上，所以被废弃掉了。直接改成了alloc_sess的时候就绑定ctx，即每个线程就指定一个ctx 我理解这个其实就是ctx_allocator adapter 方案是把ctx 封装到worker内部了，即只管怎么选worker, 如果是硬件，还是按现在这样，绑定ctx的目前get_worker 选择worker 是放在算法层 2. To longfang 之前想到的问题, 在群里也提过前提是如果用户初始化的时候init(mix) 指定了选择异构调度， a, 这个代码不好改，比如已经上传了dpdk/ceph社区 b. 即使能改，init 很费时间，uadk_engine 基本是初始化的时候就init 了，即 init 一旦选择了异构调度方案就不会随便动了。 1）流模式下，不能运行一半发生切换，如何避免即调度器如何知道现在是不是流模式，算法层的信息如何传递给调度层。 ps. adapter 方案是在算法层做的，所以直接就能判断是否是流模式 2. 如何实现threshold, 很多场景就只是小包，无论怎么优化，就是指令集快调度器如何知道包的大小，需要传给调度层 ps. adapter 方案是在算法层，直接获取包的大小，这个数据结构各算法还不一样比如req->src_len vs req->in_bytes 3. 硬件出错怎么处理，fb 异步能否实现，fb方案其实我们没验证过。代码 cipher.c wd_do_cipher_async msg_id = wd_get_msg_from_pool(&wd_cipher_setting.pool, idx, (void **)&msg); //ctx_id a drv: temp_msg = wd_cipher_get_msg(qp->q_info.idx, tag); // ctx_id_a 如果fb-> drv_b temp_msg = wd_cipher_get_msg(ctx_id_b, tag); // 这里我理解拿不到msg, 可能有坑 ps：adapter方案的做法是设标记，上层retry进来选worker[1] 4. 多个加速器，如何选, hw/ce/sve 龙芳群里的回答：指定业务运行方式，配置设备驱动不懂目前的做法删掉ce的库，然后指定sve ps：adapter方案可以在uadk.conf 配置，通过命令行也可以即生成个配置文件 /tmp/pid.conf， setenv 5. 不同平台加速器不一样，920 hw, 920b hw/ce/sve, 920c? 一套模式/算法在一个平台上调好，其他平台是否适用龙芳群里的回答：自动适配，不区分硬件平台不同算法可能有区别比如rsa 就是硬件好 cipher/digest 就是小包指令集更好。 6. 未来如果有办法读取带宽，能否/怎么支持。这个龙芳群里回答过带宽查询功能具备以后，通过驱动的get_usage()直接读取，然后再新建一个调度器根据设备利用率实施调度 ps：adapter方案可能做法是get_worker里面加if/else 【腾讯文档】adapter方案 https://docs.qq.com/doc/DRUxFaVJDdHJFUWdM
