@joevt Would you please provide more information on how to convert a device path to the formatted PciDeviceInfo bytes? Thanks!

My current theory is that I just need the device number and function number from each PCI device in the UEFI device path for the first two bytes of each node in the PciDeviceInfo path. The second two bytes I'll leave as 00 00. The last node is followed by an FF.

The following code find PCIe serial ports and outputs their paths.

ioreg -p IODeviceTree -lw0 | perl -e '
	$ioregpath=""; $pcipath=""; while (<>) {
		if ( /^([ |]*)\+\-o (.+)  <class (\w+)/ ) {
			$indent = (length $1) / 2; $name = $2; $class = $3;
			$ioregpath =~ s|^((/[^/]*){$indent}).*|$1/$name|;
			$pcipath =~ s|^((/[^/]*){$indent}).*|$1/|;
			$name = ""; $uid = 0; $classcode = "";
		}
		   if ( $class eq "IOACPIPlatformDevice" ) { if ( /^[ |]*"name" = <"([^\"]*)">/ ) { $name = $1; }; if ( /^[ |]*"_UID" = "(\d+)"/ ) { $uid = $1; } }
		elsif ( $class eq "IOPCIDevice" ) { if ( /^[ |]*"pcidebug" = "\d+:(\d+):(\d+).*"/ ) { $name = sprintf("Pci(0x%x,0x%x)", $1, $2);  } if ( /^[ |]*"class-code" = <(\w+)>/ ) { $classcode = $1; } }
		if ( /^[ |]*}/ && $name ) {
			if ( $class eq "IOACPIPlatformDevice" ) {
				   if ($name eq "PNP0A03") { $name = sprintf ("PciRoot(0x%x)", $uid); }
				elsif ($name eq "PNP0A08") { $name = sprintf ("PciRoot(0x%x)", $uid); }
				elsif ($name =~ /PNP..../) { $name = sprintf ("Acpi(%s,0x%x)", $name, $uid); }
				# not translating all ACPI types since we only care about PCI devices
			}
			$pcipath .= $name;
			if ( $classcode eq "02000700" ) {
				$serialdevicepath = $pcipath =~ s/.*PciRoot\(0x0\)//r =~ s|/Pci\(||gr =~ s|\)| 00 00 |gr =~ s|0x||gr =~ s|,| |gr =~ s|\b(\w)\b|0\1|gr =~ s|$|FF|r;
				print $ioregpath =~ s|/Root/||r . "\n";
				print $pcipath =~ s|/*||r  . "\n"; 
				print "xxd -p -r <<< \"" . $serialdevicepath . "\" | base64\n";
				print "\n";
			}
		}
	}
'

This is the result:

/PCI0@0/P0P9@9/P9P2@0/P2P4@1/PXS3@0
PciRoot(0x0)/Pci(0x9,0x0)/Pci(0x0,0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
xxd -p -r <<< "09 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 FF" | base64

/PCI0@0/P0P9@9/P9P2@0/P2P4@1/PXS3@0,2
PciRoot(0x0)/Pci(0x9,0x0)/Pci(0x0,0x0)/Pci(0x1,0x0)/Pci(0x0,0x2)
xxd -p -r <<< "09 00 00 00 00 00 00 00 01 00 00 00 00 02 00 00 FF" | base64

The following can take a UEFI device path and produce the serial PciDevicePath:

serialpath=PciRoot(0x0)/Pci(0x9,0x0)/Pci(0x0,0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)
perl -pe 's/PciRoot(0x0)//;s|/Pci\(||g;s|\)| 00 00 |g;s|0x||g;s|,| |g;s|\b(\w)\b|0\1|g; s|$|FF|' <<< "$serialpath" | xxd -p -r | base64

I'll let you know when I find out if this works.
