Hi,
i recently updated my Arch linux system, to to the following version:
Linux 4.18.6-arch1-1-ARCH #1 SMP PREEMPT
Afterwards, i noticed that something has changed regarding the realtime
permissions
and that i had to install a new package called 'realtime-priviliges',
which i never needed before,
and subsequently add my main user to the 'realtime' group.
In that wake, i updated the processor microcode, which i didn't use at
all before (there always was some
error message during bootup, but nothing else).
After being able to start JACK in realtime again, i felt that there was
a significant loss of performance.
Things that didn't cause any dropouts before now start to crackle and
gristle (as a sidenote, i mostly
use SuperCollider to make sound).
Also, and this puzzled me especially, there were dropouts, but no XRuns
... normally, when i push the
system to the limits, i get XRuns, that'd be expected. But now, it's
dropouts without, and they start way
earlier.
My machine has an Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz Processor if
that info is of user for anyone ...
Anybody else noticed something like that recently ?
Best,
nik
