6b09ff9d78 drivers/edac: pci: broken parity regression
Using the EDAC code in kernel.org kernel version 2.6.23.8 I am seeing the
following problem:

    In the kernel there is a pci device attribute located in sysfs that is
    checked by the EDAC PCI scanning code. If that attribute is set,
    PCI parity/error scannining is skipped for that device. The attribute
    is:

            broken_parity_status

    as is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directorys for
    PCI devices.

I don't think this check was actually implemented.  I have a misbehaved card
that reports a parity error every 1000 ms:

Nov 25 07:28:43 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:44 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0
Nov 25 07:28:45 beta kernel: EDAC PCI: Master Data Parity Error on 0000:05:01.0

Setting that card's broken_parity_status bit did not mask the error:

echo "1" > /sys/bus/pci/devices/0000:05:01.0/broken_parity_status

I looked through the EDAC code and did not readily see any reference to
broken_parity_status at all (which makes sense based on the behavior I am
seeing).  I applied the following patch as a proof-of-concept and now EDAC's
PCI parity error reporting behaves as documented:

bryan

Good regression find, bryan. It used to work. sigh.
I added more logic to your patch, for more coverage of the error.

48764e4143 drivers-edac: add Cell MC driver
Adds driver for the Cell memory controller when used without a Hypervisor such
as on the IBM Cell blades.  There might still be some improvements to do to
this such as finding if it's possible to properly obtain more details about
the address of the error but it's good enough already to report CE counts
which is our main priority at the moment.

3514faca19 kobject: remove struct kobj_type from struct kset
We don't need a "default" ktype for a kset.  We should set this
explicitly every time for each kset.  This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.

This patch is based on a lot of help from Kay Sievers.

d4c1465b7d drivers/edac: fix edac_pci sysfs
This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner
and the previous fixes for EDAC_MC and EDAC_DEVICE.

It removes the old (and incorrect) completion model and uses reference counts
on per instance kobjects and on the edac core module.

This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI
code was missed.  In addition, this fixes a system hang after a low level
driver was unloaded.  (A cleanup function was called twice, which really
screwed things up)

period valu to be altered via sysfs control.

This patch adds that fix on the code, and allows for the changing of the
period value as well.

b2a4ac0c28 drivers/edac: fix edac_device sysfs corner case bug
Some simple fixes to properly reference counter values from the block
attribute level of edac_device objects.  Properly sequencing the array pointer
was added, resulting in correct identification of block level attributes from
their base class functions.

Added more verbose debug statement for event tracking.

Also during some corner testing, found a bug in the store/show sequence
of operations for the block attribute/controls management.

An old intermediate structure for 'blocks' was still in the processing
pipeline.  This patch removes that old structure and correctly utilizes the
new struct edac_dev_sysfs_block_attribute for passing control from the sysfs
to the low level store/show function of the edac driver.

Now the proper kobj pointer to passed downward to the store/show
functions.

8096cfafbb drivers/edac: fix edac_mc sysfs completion code
This patch refactors the 'releasing' of kobjects for the edac_mc type of
device.  The correct pattern of kobject release is followed.

As internal kobjs are allocated they bump a ref count on the top level kobj.
It in turn has a module ref count on the edac_core module.  When internal
kobjects are released, they dec the ref count on the top level kobj.  When the
top level kobj reaches zero, it decrements the ref count on the edac_core
object, allow it to be unloaded, as all resources have all now been released.

fd309a9d8e drivers/edac: fix leaf sysfs attribute
This patch fixes and enhances the driver level set of sysfs attributes that
can be added to the 'block' level of an edac_device type of driver.

There is a controller information structure, which contains one or more
instances of device.  Each instance will have one or more blocks of device
specific counters.  This patch fixes the ability to have more detailed
attributes/controls for each of the 'blocks', providing for the addition of
controls/attributes from the low level driver to user space via sysfs.

0ca84761fa drivers/edac: fix edac_device semaphore to mutex
A previous patch changed the edac_mc src file from semaphore usage to mutex
This patch changes the edac_device src file as well, from semaphore use to
mutex operation.

Use a mutex primitive for mutex operations, as it does not require a
semaphore
