And found this theme http://forums.grsecurity.net/viewtopic.php?t=1654 So, for access ioperm() and iopl() you need disable "Disable Privileged I/O (CONFIG_GRKERSEC_IO)" option in kernel config. Can we print this message when found such configuration? Are there way to make port access without iopl()?
No. The whole reason of CONFIG_GRKERSEC_IO is to prevent you from running tools like flashrom. ;-)
