Subject: Re: [PATCH 2/2] x86, microcode: Make reload interface per system
Date: Fri, 22 Jun 2012 17:26:24 +0100	[thread overview]
Message-ID: <87d34r5n4f.fsf@spindle.srvr.nix> (raw)
In-Reply-To: <20120620101943.GE10012@aftab.osrc.amd.com> (Borislav Petkov's message of "Wed, 20 Jun 2012 12:19:43 +0200")

On 20 Jun 2012, Borislav Petkov uttered the following:

Only if supplied over the old interface. Over the new interface,
we just see

    microcode: error! Bad data in microcode data file

in the log. So clearly the driver doesn't know how to split up the
microcode.bin that Intel provides, and (until Henrique's iucode-tool or
something like it becomes ubiquitous) the old interface, and
microcode_ctl, cannot be removed.
