First off, thanks for all your hard work and late nights (and the rest of the
team) for the x86_64.
Initial results look promising with the latency test reporting figures in the
0.5 to 4 uSec range under light load. A kernel compile bumps the wost up to
9-14uSec. Firing up X,KDE, and a gamut of desktop apps really kills the
numbers though - ~267uSec being the worst recorded so far, however, once
X/KDE has started up, latencies are generally <30uSec.
One small problem to report from the compile... With
CONFIG_XENO_OPT_NUCLEUS=m, the build fails with:
WARNING: "cpu_gdt_descr" [kernel/xenomai/nucleus/xeno_nucleus.ko] undefined!
make: *** [__modpost] Error 1
What would the preferred solution be - Export cpu_gdt_descr as it is with
i386, or force xeno_nucleus to be built in ?
