CKB-DAEMON consumes 25% power of the CPU after start from hibernate/sleep mode #563

Open mrstanlez opened 7 years ago

mrstanlez commented 7 years ago

This is a problem related to my keyboard K70 RGB. OS is Linux 64 bit Manjaro XFCE 4.8(icon in systray dissapears always after start up from hibernate/sleeping mode).

CPU is used 25% of power with difference with normal start only 1% maximum. The process is ckb-daemon the consumes so more cpu power.

Please can You fix this issue ?

I've had the same high cpu usage issue with that keyboard, https://github.com/mattanger/ckb-next fork seems to be a bit better.

I'm afraid there's no easy solution for Linux. MacOS has this line which can be commented out.

I dont think so. Because after normal start all is under 1% power usage. So only we must think, how to restart ckb-daemon like it was from normal start. Correct ?

I'm not yet aware of ckb codebase, this string was just what I found so far. And I didn't find any similar one for Linux. By "no easy solution" I mean without extensive refactoring of the codebase because I suppose there isn't any easy fix either.

To me it sounds like after waking up, something goes wrong with the daemon, a pthread goes loose and starts taking up 100% of one core. @mrstanlez is your CPU a quad core?

mattanger commented 7 years ago

That is strange. So, for sure, does this happen when resuming from sleep and hibernation? Or more often with one or the other?

Hi to All, yes if the system resumes from sleep or hibernation. I resume with vlc and thunar, but only ckb-daemon will comsume a lot of power cpu. Ckb application is good, but this problem still exists. Only one solution is kill ckb-daemon and restart ckb with keyboard re-plug from USB port 3.0.

@mrstanlez: To get an idea what the daemon is running, please give us some more infos:

  1. running top or similar cmd, find out the PID of the cpu consuming process.
  2. then run "sudo strace -p PID-YOU-HAVE-FOUND 2> /tmp/foo"
  3. after 1-2 seconds abort it by pressing CTRL-C
  4. Have a look at the file /tmp/foo I think you will read endless loops of the same steps (open a file or select or something similar)
  5. Copy some of that loops into this issue here or attach the whole file (may be huge, depending on your CPU speed :-)).
