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

[PATCH 01/46] vfio: Introduce base object for VFIOContainer and targeted interface
by Zhou Wang 11 Jan '25

11 Jan '25

From: Zhenzhong Duan <zhenzhong.duan(a)intel.com> Introduce a dumb VFIOContainerBase object and its targeted interface. This is willingly not a QOM object because we don't want it to be visible from the user interface. The VFIOContainerBase will be smoothly populated in subsequent patches as well as interfaces. No functional change intended.
