Subject: [PATCH v2 0/2] arm64/PPTT ACPI 6.3 thread flag support
Date: Fri, 14 Jun 2019 17:31:56 -0500
Message-ID: <20190614223158.49575-1-jeremy.linton@arm.com> (raw)

ACPI 6.3 adds a flag to the CPU node to indicate whether
the given CPU is a thread. Add a function to return that
information for a given linux logical CPU and then utilize
it while building the arm64 topology.

v1->v2:
	Return ENOENT instead on ENONET.

  ACPI/PPTT: Add support for ACPI 6.3 thread flag
  arm64: topology: Use PPTT to determine if PE is a thread
