I have an issue that is fixed by changing the lpfc driver to run using MSI interrupts. This is done by adding “options lpfc lpfc_use_msi=2” /etc/modprobe.conf.local file.

Is there a way to make this change using kernel boot parameters?


From the Linux kernel documentation:

Module parameters for modules that are built into the kernel image
are specified on the kernel command line with the module name plus
'.' plus parameter name, with '=' and value if appropriate, such as:


Note that this is for modules that are built into the kernel. If it is compiled as a loadable module, it will have to be modprobe'd sometime after the kernel starts, and this is the correct time to pass parameters to the module.

  • The module is not built into the kernel. How do you pass parameters to the module when it loads if it is not compiled into the kernel? – countingtoten Apr 4 '11 at 22:00

    @countingtoten In /etc/modprobe.conf or related, as you originally found. – Juliano Apr 4 '11 at 22:36
