Proposed: A Tainted Performance State For The Linux Kernel

Similar to the kernel states of having a tainted kernel for using binary blob kernel modules or unsigned modules, a new tainting method has been proposed for warning the user about potentially adverse kernel performance. Dave Hansen of Intel has proposed a new "TAINT_PERFORMANCE" for the kernel that would proactively print a warning message about not using the kernel for any performance measurements. Dave explained in his RFC announcement, "I have more than once myself been the victim of an accidentally-enabled kernel configuration option being mistaken for a true performance problem. I'm sure I've also taken profiles or performance measurements and assumed they were real-world when really I was measuring the performance with an option that nobody turns on in production. A warning like this late in boot will help remind folks when these kinds of things are enabled." Read more
