Subject: [PATCH 01/10] atl1c: add workaround for issue of bit INTX-disable for MSI interrupt
Date: Sat, 28 Apr 2012 09:58:36 +0800	[thread overview]
Message-ID: <1335578325-21326-2-git-send-email-xiong@qca.qualcomm.com> (raw)
In-Reply-To: <1335578325-21326-1-git-send-email-xiong@qca.qualcomm.com>

All supported devices have one issue that msi interrupt doesn't assert
if pci command register bit (PCI_COMMAND_INTX_DISABLE) is set.
Add workaround in drivers/pci/quirks.c
