[PATCH 0/3] fix for two ACPI GTDT physical addresses

Posted by Miguel Luis 1 year, 7 months ago

The ACPI GTDT table contains two invalid 64-bit physical addresses according to
the ACPI spec. 6.5 [1]. Those are the Counter Control Base physical address and
the Counter Read Base physical address. Those fields of the GTDT table should be
set to 0xFFFFFFFFFFFFFFFF if not provided, rather than 0x0.
