Instead of blabbering further about this topic, I decided to put my code where my mouth is and spent the weekend porting the perfmon2 kernel bits, and the user bits (libpfm and pfmon) to sparc64.
As a result I've found that perfmon2 is quite nice and allows incredibly useful and powerful tools to be written. The syscalls aren't that bad and really I see not reason to block it's inclusion. I rescind all of my earlier objections, let's merge this soon :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
