Subject: [patch 38/57] PCI: fix 64-vbit prefetchable memory resource BARs
Date: Tue, 4 Nov 2008 15:32:56 -0800	[thread overview]
Message-ID: <20081104233256.GM659@suse.de> (raw)
In-Reply-To: <20081104233028.GA659@suse.de>

[-- Attachment #1: pci-fix-64-vbit-prefetchable-memory-resource-bars.patch --]
[-- Type: text/plain, Size: 1310 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Peter Chubb <peterc@gelato.unsw.edu.au>

commit e354597cce8d219d135d65e585dc4f30323486b9 upstream.

Since patch 6ac665c63dcac8fcec534a1d224ecbb8b867ad59 my infiniband
controller hasn't worked.  This is because it has 64-bit prefetchable
memory, which was mistakenly being  taken to be 32-bit memory.  The
resource flags in this case are PCI_BASE_ADDRESS_MEM_TYPE_64 |
PCI_BASE_ADDRESS_MEM_PREFETCH.

This patch checks only for the PCI_BASE_ADDRESS_MEM_TYPE_64 bit; thus
whether the region is prefetchable or not is ignored.  This fixes my
Infiniband.
