Yes, this is justified by the fact that the kernel interface currently supports up to 320 registers. So 256 was too small to cover for it. I decided to double it to be okay for a while. We could reduce it to 320 as well. -- -Stephane _______________________________________________ perfmon mailing list [email protected] http://www.hpl.hp.com/hosted/linux/mail-archives/perfmon/
