** Package changed: ubuntu => microcode-initrd (Ubuntu)
** Changed in: microcode-initrd (Ubuntu)
Status: New => Fix Released
** Also affects: microcode-initrd (Ubuntu Focal)
Importance: Undecided
Status: New
** Changed in: cloud-images
Status: New => Fix Committed
** Description changed:
+ [Impact]
+
+ * New package to provide micorocode-only initrd for application of
+ microcode on boot, when otherwise no initrd is in use.
+
+ [Test Case]
+
+ * install microcode-initrd in AWS cloud x86 metal instance
+ * reboot, observe that microcode has been applied, and yet the boot was
without initrd (observe journalctl -b -k to see that initrd was not used for
boot)
+
+ [Regression Potential]
+
+ * This is a brand new package, that will be used by AWS images.
+ Otherwise this package will not be automatically installed anywhere. Re
+ spinning & promoting AWS images are tested and gated by the CPC team.
+
+ [Other Info]
+
+ * Original bug report for groovy:
+
Normally Ubuntu boots using initrd that has three archives: early amd64
microcode, early intel microcode, and compressed main initrd.
When booting without initrd, simply kernel is loaded without any initrd
and thus without microcode.
However, grub supports booting with multiple initrds and one can specify
a standalone early initrd which contains microcode only, and separate
main initrd.
As an added bonus one can also specify just eary microcode initrd
without a main one, to allow kernel to load microcode early, but
otherwise boot without an initrd.
To achieve that I need to introduce a microcode-initrd package will will
only provide early initrd which only has microcode.
The intention is to seed microcode-initrd to targets that boot on
baremental without initrd.
** Summary changed:
- ITP: Please support loading microcode early, whilst otherwise booting without
initrd
