My memory was that there was some issue of "legacy" PCIe devices showing up as duplicated and some change was put in that avoided that --but prevented "modern" PCIe devices from working. As I remember, disabling the change was one reason Greg created his variant: upstream choose which type of devices it wanted to support and Greg went the other way. (No one has support covering both contexts on the MACCHIATObin Double Short?) Looking, there was a Greg edk2-platforms update called "remove ECAM shift" that seems to be involved with that area. (Also, removal of a headless flag in FADT and adding 3 PCIe defines and some MDEPKG_NDEBUG #if changes and having some CLANG DLINK flags. My context was still actually headless but I noticed no problems from that.) There were also edk2 additions of 3 lines involving something like: MdeModulePkg/Bus/Pci/NvmExpressDxe/NvmExpressDxe.inf plus some other stuff that might be for other issues. More enabling of clang use as well. I've not tested a mainline build to check on the status of such things. But back on 2020-Jul-01 when the commits were made, Greg appearently throught that they were necessary to get his context to work. (My test context seemed to be covered as well but I did not prove Greg's variation was necessary for coverage.) > EspressoBin (and Armada 3720 in general) is very well supported - > apart from PCIE, everything should work. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
