intel-microcode: Add ability to filter microcode

2014-10-21T20:50:37+00:00

The microcode data file released by Intel has microcode for many Intel processors, which by default all get installed onto the target image. In some situations it may desirable to choose microcode for only a selected processor or processors. This change provides an easier way to filter and select only the microcode of interest for BSPs from recipe space. A new variable, UCODE_FILTER_PARAMETERS, is introduced, which can be defined to contain parameters to the iucode_tool which will filter the microcode of interest for the BSP under consideration. More information on the iucode-tool parameters is available here: http://manned.org/iucode-tool. This filtering makes the generated microcode files very machine-specific, hence making the recipe machine-specific. BSPs using the common Intel kernel will not be using the filtered microcode, and will be able to share the intel-microcode packages with the common Intel package arch for the recipe.

package_deb doesn't yet handle non-ASCII characters in control files, so remove a unicode "registered trademark" character. Signed-off-by: Ross Burton Signed-off-by: Tom Zanussi

intel-microcode: a recipe for Intel microcode datafile

2014-09-04T13:46:30+00:00

This recipe provides the microcode datafile for Intel Processors. The recipe provides: 1. microcode.dat file for microcode updating from user space with the iucode-tool utility. 2. the microcode cpio file which gets bundled with the initrd to support microcode loading at early boot time.

iucode-tool: a new recipe for loading Intel CPU microcode

2014-09-04T13:44:50+00:00

iucode_tool is a program to manipulate Intel i686 and X86-64 processor microcode update collections, and to use the kernel facilities to update the microcode on Intel system processors. Signed-off-by: Ross Burton Signed-Off-By: Nitin A Kamble Reviewed-by: Darren Hart Signed-off-by: Tom Zanussi
