Subject: [PATCH 0/2] cxl/pci: Inactive downstream port handling
Date: Wed, 5 Mar 2025 11:01:21 +0100	[thread overview]
Message-ID: <20250305100123.3077031-1-rrichter@amd.com> (raw)

A small series with individual patches to handle inactive downstream
ports during enumeration. First patch changes downstream port
enumeration to ignore those with duplicate port IDs. Second patch only
enables active downstream ports with the link status up.

Patches are independent each and can be applied individually.

Robert Richter (2):
  cxl/pci: Ignore downstream ports with duplicate port IDs
  cxl/pci: Check link status and only enable active dports
