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 -- J.A.
