I run a SiliconDust tuner that converts OTA TV to mp2, which I'm then
able to play back using mplayer. An hard-wired ethernet connection is
used between the tuner and the main CPU.
I notice that there are leftover kworker processes. They are mostly idle
and only a few have non-zero time, and then at most only a couple of
seconds.
I don't know why you think they are "leftover". They are kernel
processes that are started internally as necessary.
For example,
87547 ? I 0:00 [kworker/u16:1-phy0]
87554 ? I 0:00 [kworker/7:2-events]
87555 ? I 0:00 [kworker/5:2-events]
87556 ? I 0:00 [kworker/u16:2-btrfs-endio-write]
87557 ? I 0:00 [kworker/u16:3-btrfs-delalloc]
87558 ? I 0:00 [kworker/u16:5-btrfs-endio-write]
87559 ? I 0:00 [kworker/u16:7-events_unbound]
87560 ? I 0:00 [kworker/u16:9-btrfs-freespace-write]
87561 ? I 0:00 [kworker/u16:10]
87626 ? I< 0:00 [kworker/u17:1]
On my computer right now:
$ ps auxw | grep kworker | wc -l
84
Should I be concerned? In particular, I was not aware that I had
installed the btrfs filesystem.
btrfs is the default now, but if you aren't using it, I don't know why
those would be there. But in general, kworker processes are normal.
