AMD microcode updates.

Colin Ian King-2
Hi,

I think we should consider supporting AMD microcode updates for Natty.
The kernel microcode driver is able to load the AMD microcode file
automatically from /lib/firmware/amd-ucode/microcode_amd.bin when the
module is loaded using the firmware loading infrastructure, so we don't
need to mess around with user space tools like the Intel microcode_ctl·

The microcode is available at:
http://www.amd64.org/support/microcode.html (tarball at:
http://www.amd64.org/index.php?id=50&file=amd-ucode-latest.tar)

The caveat is we need some careful inspection of the Software License
Agreement.

Colin

The legalese in the download page is beyond me.

Me too. Perhaps I should punt this to some legal experts.

After taking to legal, this is ok to ship provided we distribute
everything in the tarball as part of the package.

Only questions I have are:

1. Is this going to be a separate package, or part of the existing
microcode package?

2. if #1 is separate then who is doing the MIR?

If we model it after the Intel method for packaging CPU microcode, then
#1. I'm also quite happy with having this new package live in Universe
right alongside intel-microcode. No MIR required for Universe packages.
