[meta-intel] [PATCH 09/10] core-image-minimal-initramfs: extend to support early microcode loading

2014-06-20 Thread nitin . a . kamble 
From: Nitin A Kamble 

Consumes the intel-earlyload-microcode-image to generate an initrd which is
extended with the earlyload microcode support.

This recipe now generates this additional initrd image:
  core-image-minimal-initramfs-${MACHINE}.cpio.gz.ucode

This takes effect for *all* machines/distros and is therefore not an
acceptable thing to be doing, at the very least this needs to be x86
only using some form of override. 

It again makes me think that using image generation for that image type
is perhaps not the best option...

Cheers,

Richard

Re: [meta-intel] [PATCH 09/10] core-image-minimal-initramfs: extend to support early microcode loading

2014-06-24 Thread Burton, Ross 
Hi,

I've been having a quick look at the image generation code and am
wondering if appending supplementary cpio blobs to an initramfs is
something that is actually common and we should add support for that
directly to the initramfs generation.

Alternatively, using IMAGE_POSTPROCESS_COMMAND in
core-image-minimal-initramfs.bbappend should let you trivially append
a cpio (generated directly using cpio, not image.bbclass) to the
generated image.

I think it is not common. But like there are uboot pieces, we can add x86 ucode 
pieces.

This along with RP's do_deploy solution should give the same results as my 
initial ucode image solution. I am trying these out now.
