It doesn't really gain anything from being static, aside from requiring odd udev rules and/or init scripts to load it.

We had this discussion yesterday on irc, but I never really got this in my head.

It works ok with microcode.dat, but what happens if Intel release an update in /lib/firmware/intel-ucode/$f-$m-$s format ?

The driver will do a request_firmware, but if we build the driver in, we'll be in the initrd, where that file won't exist. To make it work, we'll either have to..

- have the firmware in the initramfs

or

- pretend the request_firmware didn't happen, and have the initscript continue to do the microcode_ctl

Which direction are we moving in ?
