      [PATCH] PCI Bus Parity Status-broken hardware attribute, EDAC foundation · bd8481e1
      由 Doug Thompson 提交于 
      Currently, the EDAC (error detection and correction) modules that are in
the kernel contain some features that need to be moved. After some good
feedback on the PCI Parity detection code and interface
(http://www.ussg.iu.edu/hypermail/linux/kernel/0603.1/0897.html) this
patch ADDs an new attribute to the pci_dev structure: Namely the
'broken_parity_status' bit.

When set this indicates that the respective hardware generates false
positives of Parity errors.

The EDAC "blacklist" solution was inferior and will be removed in a
future patch.

Also in this patch is a PCI quirk.c entry for an Infiniband PCI-X card
which generates false positive parity errors.

I am requesting comments on this AND on the possibility of a exposing
this 'broken_parity_status' bit to userland via the PCI device sysfs
directory for devices. This access would allow for enabling of this
feature on new devices and for old devices that have their drivers
updated. (SLES 9 SP3 did this on an ATI motherboard video device). There
is a need to update such a PCI attribute between kernel releases.

This patch just adds a storage place for the attribute and a quirk entry
for a known bad PCI device. PCI Parity reaper/harvestor operations are
in EDAC itself and will be refactored to use this PCI attribute instead
of its own mechanisms (which are currently disabled) in the future.

      [TG3]: 40-bit DMA workaround part 2 · 4a29cc2e
      由 Michael Chan 提交于 
      The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.

For example, some 4-port card or mother board designs have 5704 behind
the 5714.

All devices behind the EPB require the 40-bit DMA workaround.

Thanks to Chris Elmquist again for reporting the problem and testing
the patch.
