[SOLVED] Process priority not applying to restarted music servers and players

[Snoopy8]

For Activated version.

When the music server/player was restarted from the Music Player tab, it did not pick up the Process Priority specified in the SnakeOil tab.  Process Priority worked when system was booted/rebooted.

Good catch.. Filed a ticket here.

I may do a quick release to fix this in the weekend if I can, and push the GUI revamp to U2.

What else will be in quick release?  Will most of the issues tagged "Gear Isolation U1" be included?

Those will be moved to U2 :p

This is fixed in Gear Isolation U1. Note the priority will only be applied approximately 25 seconds later, this is to allow the players enough time to fully initialise.

Thank you for fix in 1.2.1

Found a further issue with LMS.  Have set the priority  of squeezeboxserve to 50, but only one of the processes 1146 has been changed.  1148 has not been changed.

Code:

tuna --show_threads | grep squ
  1146      RR    50  0,1,2,3        10            8 squeezeboxserve
  1148   OTHER     0  0,1,2,3      1610         9323 squeezeboxserve
  1204      RR    50  0,1,2,3        24           70 squeeze2upnp-x8

Depending on when LMS starts the threads, e.g. when u play a song, or when it does a background task, Snakeoil may not be able to trap all. I can probably keep checking every X seconds and move threads to real time, but that could make it worse. I guess a combination of this with cpuset is probably the way to go?

Will see how it goes later down the road.

As background, my limited knowledge prevented me from getting cset itself (using -e option) to start lms; had to start lms, then move it to a specific cpuset.  That was when I discovered that there was more than one squeezeboxserve process. 


It becomes more "fun" when cpusets are involved, and there is not option to set a process priority.  But I will leave it in your capable hands to figure it out, when the time comes...

It looks like the problem has gone away in LMS 8.2 where there is now only 1 Squeezeboxserve process. Previously in 8.1, there were 2.

Is 8.2 any good audio quality wise?
