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.

Me too. Perhaps I should punt this to some legal experts. > > -- > Tim Gardner [hidden email] > -- kernel-team mailing list [hidden email] https://lists.ubuntu.com/mailman/listinfo/kernel-team |

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? ~pete -- Pete Graner <[hidden email]> Manager Ubuntu Kernel Canonical Ltd. http://www.canonical.com/ -- kernel-team mailing list [hidden email] https://lists.ubuntu.com/mailman/listinfo/kernel-team |

I'm also quite happy with having this new package live in Universe right alongside intel-microcode. No MIR required for Universe packages. rtg -- Tim Gardner [hidden email] -- kernel-team mailing list [hidden email] https://lists.ubuntu.com/mailman/listinfo/kernel-team |
