And this continues to be the case for the mm3 and mm4 kernels.
Some testing here indicates that if I replace *all* the glx stuff with
that from MesaLibs, I get around 550 fps, but with 100% cpu going to
glxgears. glxinfo says drm = no
With the 6.8.1 glx stuff installed, glxinfo says drm - yes, and I get
10 fps at 0% cpu, even at full screen, something the MesaLibs stuff
can't handle at all. Other screen actions do seem to be quite snappy
even if glxgears is a crippled dog.
Noting John Smirls announce on lkml just now, I wonder if I should be
a tester of his new drm?
