[edk2-devel] [PATCH v1] OvmfPkg: Use DxeRuntimeCapsuleLib from DxeCapsuleLibFmp in X64 builds
Posted by Tomas Pilar (tpilar) 4 years, 9 months ago
Switching to this library enables capsule support for FMP devices. Simple
tests show that a capsule with an embedded driver now updates using
CapsuleApp.

I don't have a problem with this change unless it affects the code
size considerably.

However, isn't this only useful for updating the firmware on PCI cards
from within a VM when they are passed through from the host to the
guest? I understand this is a useful test scenario for you, but at
least clarify this in the commit log.

The library itself is tiny. The use case you describe is exactly what I am using at the moment.
I can imagine that software testing FMP implementation APIs is also something that might be
useful. I will clarify in the commit.
