Subject: [PATCH 1/3] fix on Store individual VF BAR size in struct pci_sriov
Date: Thu,  5 Feb 2015 14:34:23 +0800	[thread overview]
Message-ID: <1423118065-6250-2-git-send-email-weiyang@linux.vnet.ibm.com> (raw)
In-Reply-To: <1423118065-6250-1-git-send-email-weiyang@linux.vnet.ibm.com>

__pci_read_base() will return 1 when it is a 64-bit BAR, which makes the
resource index not correct. So i could not be the index in this case.
