[edk2-devel] About the feasibility of detaching Fdt16550SerialProtHookLib from ArmVirtPkg

Hi Ard,

I'm porting the LoongArch virt-machine to edk2. LoongArch virt-machine 
uses Fdt16550SerialPortHookLib to handle the UartBase, and the 
gEarly16550UartBaseAddressGuid is defined in ArmVirtPkg.dec.

I think this library can be used in other Arch, like RISC-V LoongArch 
and so on, so can we feasibility this library into OvmfPkg?

Hope to hear back from you.


Thanks,
Chao

Sorry, the last mail was misspelled, what I meant was: can we detaching 
the Fdt16550SerialPortHookLib into OvmfPkg?


Thanks,
Chao

Yes, OvmfPkg is the home for virtualization-related packages.  We moved
libs from ArmVirtPkg to OvmfPkg before so risc-v can easily share them.

take care,
  Gerd

Hi Gerd,

So, what I understand that is I can move the Fdt16550SerialPortHookLib 
into OvmfPkg?


Thanks,
Chao

Ok, I will move this lib when submit LoongArch virtual-machine patch set.
