[edk2-devel] Help getting Capsule-On-Disk working (CapsuleOnDiskLoadPei and gEdkiiPeiBootInCapsuleOnDiskModePpiGuid)

["Rebecca Cran" <rebecca@bsdio.com>]

I'm trying to get capsule-on-disk support added to some firmware, and 
while I can get the CoD via NVRAM method working (where fwupd-efi runs 
as a boot option) I'm struggling to get the native CoD process working 
where I'm expecting to be able to see a progress bar as firmware is 
flashed. At the moment I see OsIndications being set correctly, but I'm 
missing some driver to handle it.


Should I be using CapsuleOnDiskLoadPei? If so, where is 
gEdkiiPeiBootInCapsuleOnDiskModePpiGuid supposed to get produced? I 
don't see any drivers that PRODUCES it - is each platform supposed to 
implement it?

I'm working on an AArch64 system where I'm pretty sure memory isn't 
retained between reboots so Capsule-In-Memory won't work.
