Subject: [PATCH 0/4]: Resolve MSI vs. INTX_DISABLE quirks, V2.
Date: Thu, 25 Oct 2007 01:14:45 -0700 (PDT) [thread overview]
Message-ID: <20071025.011445.80152909.davem@davemloft.net> (raw)
Ok, I've respun the patches including all of the feedback I've
obtained. Again, it's at:
kernel.org:/pub/scm/linux/kernel/git/davem/msiquirk-2.6.git
Greg, I think this stuff is ready to go so if you would pull
them in I would really appreciate it.
These changes clean up the handling of the common quirk wherein
setting INTX_DISABLE will mistakedly disable MSI generation for some
devices.
For devices without that problem, we want to keep the pci_intx() calls
in drivers/pci/msi.c because those help protect against devices with
the opposite problem. Such devices always generate INTX interrupts
even when MSI is enabled, unless INTX_DISABLE is set.
In addition to the Tigon3 cases, I added quirk entries for the
SB700/800 SATA chips and the IXP SB400 USB controllers. And as
a result of the latter we can remove several AMD full-chipset
MSI disable quirks which are no longer necessary.
