Hello, i am working on improving the driver for hauppauge PVR cards (multimedia/pvrxxx). i just implemented a "fast" interrupt using a taskqueue ( like the new if_em driver ). i have a couple of questions: 1. if_em is using taskqueue_enqueue rather than taskqueue_enqueue_fast. this is contrary to what "man taskqueue" claims. how come? 2. when my capture-device is closed, i need to drain the taskqueue. however, taskqueue_drain needs a task as an argument. but i have queued 2 different tasks on the taskqueue. what to do? i guess they need to be processed "in order". 3. when and in which version will the "fast" versions of the taskqueue-functions be released? will it be backported? if i create a patch and send-pr it, is it likely to be accepted for 6.x? i am developing this on 6.1-p10, but i imported subr_taskqueue.c and taskqueue.h from cvs. thank you for your time, usleep
