Hi all...
Just a comment about a weird thing I have noticed wrt scheduling in latest
kernels.
My last two tests are 2.6.7-mm2 and 2.6.7-mm2+staircase-7.4 (plus a couple
other things, like aic updated driver). I use GLMatrix as screensaver,
running with nVidia drivers (yup, tainted kernels, but both are tainted ;)).
What I have noticed:
- With standard -mm, as GLMatrix runs, the framerate drops even to something
like a frame every couple seconds
- With staircase, it keeps running smoothly at 25fps.
Something is strange in -mm. It keeps stoling cycles to the screensaver.
Is this expected ?
TIA
