From 78e883585db49aa6d86b8817b770d7717699ab4e Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Thu, 22 Jan 2015 11:15:43 -0700 Subject: [PATCH] PCI: Add Wellsburg (X99) to Intel PCH root port ACS quirk Intel has confirmed that the Wellsburg chipset, while not reporting ACS, does provide the proper isolation through the RCBA/BSPR registers, so the same quirk works for this set of device IDs.
