early intel microcode
« on: 2014/10/29, 19:54:12 »
I managed to create a valid initr.img holding:
Code: [Select]
# lsinitrd icoreduo.img
Image: icoreduo.img: 25K
========================================================================
Version:

Arguments:
dracut modules:
========================================================================
drwxr-xr-x   2 root     root            0 Oct 29 19:00 kernel
drwxr-xr-x   2 root     root            0 Oct 29 19:00 kernel/x86                                         
drwxr-xr-x   2 root     root            0 Oct 29 19:00 kernel/x86/microcode                               
-rw-r--r--   1 root     root        24576 Oct 29 19:00 kernel/x86/microcode/GenuineIntel.bin               
========================================================================
Now dmesg shows
Code: [Select]
# dmesg |grep microcode
[    0.000000] CPU0 microcode updated early to revision 0xa0b, date = 2010-09-28
[    0.006666] CPU1 microcode updated early to revision 0xa0b, date = 2010-09-28
[    0.567774] microcode: CPU0 sig=0x1067a, pf=0x80, revision=0xa0b
[    0.567784] microcode: CPU1 sig=0x1067a, pf=0x80, revision=0xa0b
[    0.567869] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba
The 5 seconds later occurence of "Microcode Update Driver: v2.00"
I dont know where this comes from : I have removed all of /lib/firmware/microcode.dat,iucode-intel files
. . . I am just about to reboot using a newly created dracut initrd file . . .

[edit]
not better with a new initrd, the depreciated update driver was not called by the initrd:
Code: [Select]
# dmesg |grep microcode
[    0.000000] CPU0 microcode updated early to revision 0xa0b, date = 2010-09-28
[    0.006666] CPU1 microcode updated early to revision 0xa0b, date = 2010-09-28
[    0.458514] microcode: CPU0 sig=0x1067a, pf=0x80, revision=0xa0b
[    0.458524] microcode: CPU1 sig=0x1067a, pf=0x80, revision=0xa0b
[    0.458623] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba
I will try again to get rid of the traditional "Microcode Update Driver" by deinstalling the
package intel-microcode

[edit] I am not getting rid of ... but I am pretty sure the old Update Driver has nothing left to use to update from.
