如果是硬件加速卡未执行完,需要放弃cpu控制权,它可以调用ASYNC_pause_job把控制权交还给用户态。比如说:硬件加速卡engine加密接口afalg_fin_cipher_aio这个有调用ASYNC_pause_job,当进行aio拷贝的时候,把加解密原始数据拷贝到内核层(硬件加速卡),然后通过ASYNC_pause_job(底层实现是通过async_fibre_makecontext)把控制...

协程的本质是对cpu的分时复用,所以,我们讨论job的时候,就是在讨论cpu的时间片分配。 ssl调用了async_start_job之后,便进入了job 2356流程,当job执行完23之后,会调用api ASYNC_pause_job() 切换回主job,并将job状态设置为ASYNC_PAUSE, 这个时候CPU会交还给主job完全其他计算工作,qat并行的进行他自己的计算。 主j...
Withasync def, Python knows that, inside that function, it has to be aware ofawaitexpressions, and that it can "pause" ⏸ the execution of that function and go do something else 🔀 before coming back. When you want to call anasync deffunction, you have to "await" it. So, this ...
