Hi Olivier,
I've write something to express my idea, it would be great if you can
try it.
It's totally untested and only does polling in sqthread, won't be
hard
to expand it to cqring_wait. My original idea is to poll all the napi
device but seems that may be not efficient. so for a request, just
do napi polling for one napi.
There is still one problem: when to delete the polled NAPIs.
I think that I have found an elegant solution to the remaining problem!
Are you ok if I send out a patch to Jens that contains your code if I
put your name as a co-author?
No problem, go ahead.
+ ne = kmalloc(sizeof(*ne), GFP_KERNEL);
+ if (!ne)
+ return;
+
+ list_add_tail(&ne->list, &ctx->napi_list);
+}
ne->napi_id is not initialized before returning from the function!
Yes, feel free to enhance this code and fix bugs.
