I have an efl application which starts some pthreads, each one starting
a shell (with ecore_exe_run) :
terminology -e vim xxxxx
I see these processes in htop, and I see that each terminology thread
"uses" a "full" core and 100%CPU (sometimes 96%...).
Nobody is typing in vim....
Why do they use 100%CPU ? Is it true or is it an error of htop...?
threads may be doing different things depending on the thread. efl starts a
bunch of threads (3 or 4 at least) generally speaking. one may be the vsync
event thread which does very little except tries to exactly wake up when either
a vsync event comes in from the drm/drm/kms driver core or use a clock based
timer instead if that doesn't work. one could be evas's slave thread it wakes
up for software rendering. one could be a special software scaler thread for
scaling image data for the software engine.... one the main loop.
now something shouldn't be using 100% cpu. that doesn't sound right. i don't
see this here so... something special in your environment is different causing
this to happen... what is it? where is it consuming the cpu? why?
Mmm, thank you. es that deos not sound right...
