From 026f84d3fa62d215b11cbeb5a5d97df941e93b5c Mon Sep 17 00:00:00 2001 From: Subramanian Ananthanarayanan Date: Fri, 6 Sep 2024 10:52:27 +0530 Subject: [PATCH 1/2] PCI: Add ACS quirk for Qualcomm SA8775P MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Qualcomm SA8775P root ports don't advertise an ACS capability, but they do provide ACS-like features to disable peer transactions and validate bus numbers in requests. Thus, add an ACS quirk for the SA8775P.

Thus, quirk the device to mark INTx masking as broken.
