What's behind the following ACPI error messages?

I am seeing the following ACPI error messages during boot for quite some time now. Can someone please explain what they mean and help me evaluate if they are of importance? Or even worth a bug report?

ACPI Error: Method parse/execution failed _PR.CPU0._PDC, AE_AML_OPERAND_TYPE (20170728/psparse-550) ACPI Exception: AE_AML_OPERAND_TYPE, While resolving operands for [OpcodeName unavailable] (20170728/dswexec-461) ACPI Error: Needed type [Reference], found [Integer] ffff8d2fcfbc90d8 (20170728/exresop-103)

Not sure if related, but I am also seeing this one:

Error parsing PCC subspaces from PCCT
