[edk2-devel] [edk2-platforms][PATCH v1] MinPlatformPkg: Update FADT-related PCD defaults to restore behaviour
Posted by Benjamin Doron 1 year, 10 months ago 
Commit f427247 (MinPlatformPkg: Add PCDs to update FADT entries from
board package) modified AcpiPlatform flow, altering the FADT for all
platforms. Now, because `FadtHeader->Gpe0BlkLen == 0`, the Linux kernel
prints "irq 9: nobody cared ..." - GPE status cannot be retrieved and
at least ACPI SCIs cannot be handled correctly. As the size of this
register is the same on Skylake/Kabylake and TigerLake, update the PCD
default value.

Several FADT register block AccessSize PCDs are updated as well. These
fields too are the same between Skylake/Kabylake and TigerLake. However,
other fields differ between platforms, such as GPE0 address and the
removal of PM{1,2}* addresses, which should be handled in a follow-up.
