Subject: [PATCH] DynamicTablesPkg: AcpiSsdtPcieLibArm : Add UID to slot creation
Date: Mon, 22 Aug 2022 10:21:01 -0600 [thread overview]
Message-ID: <1dc8a5cb9e3965f6adb5b84a722401d70fe11d8e.1661185223.git.jbrasen@nvidia.com> (raw)
Expose the UID value to GeneratePciSlots().
This is needed for some cases for example:
https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#identifying-externally-exposed-pcie-root-ports
