Subject: Regression: pci=realloc fails to modify bridge windows, causing devices to fail BAR allocation
Date: Thu, 31 Jul 2014 09:14:18 +0100	[thread overview]
Message-ID: <53D9FADA.6020304@iam.tj> (raw)

See https://bugzilla.kernel.org/show_bug.cgi?id=81431

Summary:

Up until v3.15.7 booting with "pci=realloc,use_crs" successfully modifies the PCI bridge windows to allow an external ExpressCard <> ViDock4 + Nvidia Quadro NVS420 with its 2 GPUs to be configured.

With v3.16rc6 and rc7 it fails to do this, leaving the NVS420 inoperable.
