Release has been announced here. http://lists.debian.org/debian-user/2013/09/msg00126.html This update needs to be added to the meta-intel layer. 36504 1 ross.burton 2013-09-10 19:28:37 +0000 I can take this. 36918 2 ross.burton 2013-09-18 22:37:09 +0000 http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-contrib/log/?h=ross/ucode has basic recipes for the microcode and the tool. Just need to actually glue them together now. 41130 3 alexandrux.palalau 2014-03-12 10:31:15 +0000 Any ideea if this is going to make 1.6? 41131 4 ross.burton 2014-03-12 10:37:37 +0000 It's a feature, so no. The tricky bit is integrating the loader into the early boot (ie initramfs) so we should bump this to 1.7. 44047 5 nitin.a.kamble 2014-06-18 01:52:34 +0000 I have few commits which will get this implemented. Testing the commits now. 44133 6 nitin.a.kamble 2014-06-20 23:24:41 +0000 Sent the commits to meta-intel mailing list. 45026 7 nitin.a.kamble 2014-08-07 18:51:42 +0000 keeping this on hold for a while. Meanwhile these side tasks are ongoing related to this work: * I proposed Intel publishing the microcode data files through linux-firmware, to make it easier for the Linux community. I had good discussions with the people involved, and there is a good chance this will happen in a week or 2. Once this happens then the intel-microcode recipe can go away, which simplifies the licensing issue. * The INITRD variable usage is changed in the oecore layer. Now multile filesystem images can be specified, which makes the code for bundling the microcode in the initrd much simpler. 45360 8 nitin.a.kamble 2014-09-02 16:36:07 +0000 We are working to get the Intel microcode published through the linux-firmware repository hosted on kernel.org. It is taking some time, and till that happens the intel-microcode recipe is used to fetch the Intel microcode data. When the Intel microcode is available through the linux-firmware repository, at that time the intel-microcode recipe will be replaced by extensions to the linux-firmware recipe. 45497 9 nitin.a.kamble 2014-09-09 16:24:50 +0000 commit 50abd223b626fc7508e24b55fc1b22c7b3a66e97 Author: Nitin A Kamble <nitin.a.kamble@intel.com> Date: Tue Jun 17 18:10:54 2014 -0700 meta-intel BSPs: enable microcode loading support for images For the BSPs using the meta-intel.inc file enable the early boot-time kernel as well as the user space microcode loading support.

With the exception of few, many of the meta-intel BSP configuration files already include the meta-intel.inc file. With this commit now, all the remaining BSPs from the meta-intel layer also include the meta-intel.inc file. The Intel platforms BSPs hosted outside of the meta-intel layer, such as minnow, need to include the meta-intel.inc file to get the common features from the meta-intel layer.
