62456726d7 Fix 82875 PCI setup
The 82875 EDAC driver enables an otherwise-hidden PCI device, but doesn't
register it as a PCI device properly.  Therefore, the device list in
/proc/bus/pci/devices is different than the tree in /sys/bus/pci.  This
usually manifests as the X server failing to start, since it expects the
two lists to be consistent.

9794f33dde [PATCH] EDAC: Add Fully-Buffered DIMM APIs to core
Eric Wollesen ported the Bluesmoke Memory Controller driver for the Intel
5000X/V/P (Blackford/Greencreek) chipset to the in kernel EDAC model.

This patch incorporates those required changes to the edac_mc.c and edac_mc.h
core files by added new Fully Buffered DIMM interface to the EDAC Core module.

4f423ddf56 [PATCH] EDAC: Add memory scrubbing controls API to core
This is an attempt of providing an interface for memory scrubbing control in
EDAC.

This patch modifies the EDAC Core to provide the Interface for memory
controller modules to implment.

The following things are still outstanding:

 - K8 is the first implemenation,

   The patch provide a method of configuring the K8 hardware memory scrubber
   via the 'mcX' sysfs directory.  There should be some fallback to a generic
   scrubber implemented in software if the hardware does not support
   scrubbing.

   Or .. the scrubbing sysfs entry should not be visible at all.

 - Only works with SDRAM, not cache,

   The K8 can scrub cache and l2cache also - but I think this is not so
   useful as the cache is busy all the time (one hopes).

   One would also expect that cache scrubbing requires hardware support.

 - Error Handling,

   I would like that errors are returned to the user in "terms of file
   system".

 - Presentation,

   I chose Bandwidth in Bytes/Second as a representation of the scrubbing
   rate for the following reasons:

   I like that the sysfs entries are sort-of textual, related to something
   that makes sense instead of magical values that must be looked up.

   "My People" wants "% main memory scrubbed per hour" others prefer "%
   memory bandwidth used" as representation, "bandwith used" makes it easy to
   calculate both versions in one-liner scripts.

   If one later wants to scrub cache, the scaling becomes wierd for K8
   changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to
   "blocks of 64 bit".  Using "bandwidth used" makes sense in all three cases,
   (I.M.O.  anyway ;-).

 - Discovery,

   There is no way to discover the possible settings and what they do
   without reading the code and the documentation.

   *I* do not know how to make that work in a practical way.

 - Bugs(??),

   other tools can set invalid values in the memory scrub control register,
   those will read back as '-1', requiring the user to reset the scrub rate.
   This is how *I* think it should be.

 - Afflicting other areas of code,

   I made changes to edac_mc.c and edac_mc.h which will show up globally -
   this is not nice, it would be better that the memory scrubbing fuctionality
   and interface could be entirely contained within the memory controller it
   applies to.

Frithiof Jensen

edac_mc.c and its .h file is a CORE helper module for EDAC
driver modules. This provides the abstraction for device specific
drivers. It is fine to modify this CORE to provide help for
new features of the the drivers

9962fd017b [PATCH] EDAC: e752x byte access fix
The reading of the DRA registers should be a byte at a time (one register at a
time) instead of 4 bytes at a time (four registers).  Reading a dword at a
time retrieves erroneous information from all but the first register.  A
change was made to read in each register in a loop prior to using the data in
those registers.

49c0dab7e6 [PATCH] Fix and enable EDAC sysfs operation
When EDAC was first introduced into the kernel it had a sysfs interface,
but due to some problems it was disabled in 2.6.16 and remained disabled in
2.6.17.

With feedback, several of the control and attribute files of that interface
had some good constructive feedback.  PCI Blacklist/Whitelist was a major
set which has design issues and it has been removed in this patch.  Instead
of storing PCI broken parity status in EDAC, it has been moved to the
pci_dev structure itself by a previous PCI patch.  A future patch will
enable that feature in EDAC by utilizing the pci_dev info.

The sysfs is now enabled in this patch, with a minimal set of control and
attribute files for examining EDAC state and for enabling/disabling the
memory and PCI operations.

The Documentation for EDAC has also been updated to reflect the new state
of EDAC operation.

2d7bbb91c8 [PATCH] EDAC: mc numbers refactor 1-of-2
Remove add_mc_to_global_list().  In next patch, this function will be
reimplemented with different semantics.

1 Reimplement add_mc_to_global_list() with semantics that allow the caller to
  determine the ID number for a mem_ctl_info structure.  Then modify
  edac_mc_add_mc() so that the caller specifies the ID number for the new
  mem_ctl_info structure.  Platform-specific code should be able to assign the
  ID numbers in a platform-specific manner.  For instance, on Opteron it makes
  sense to have the ID of the mem_ctl_info structure match the ID of the node
  that the memory controller belongs to.

2 Modify callers of edac_mc_add_mc() so they use the new semantics.

96941026a5 [PATCH] EDAC Coexistence with BIOS
Address the issue of EDAC/BIOS coexistence for the e752x chip-sets.

We have found a problem where the BIOS will start the system with the error
registers (dev0:fun1) hidden and assuming it has exclusive access to them.
The edac driver violates this assumption.

The workaround this patch offers is to honor the hidden-ness as an
indication that it is not safe to use those registers.

472678ebd3 [PATCH] EDAC: kobject/sysfs fixes
- After we unregister a kobject, wait for our kobject release method
  to call complete().  This causes us to wait until the kobject
  reference count reaches 0.  Otherwise, a task accessing the EDAC
  sysfs interface can hold the reference count above 0 until after the
  EDAC module has been unloaded.  When the reference count finally
  drops to 0, this will result in an attempt to call our release
  method inside the EDAC module after the module has already been
  unloaded.

  This isn't the best fix, since a process can get stuck sleeping forever
  uninterruptibly if the user does the following:

      rmmod my_module < /sys/my_sysfs/file

  I'll go back and implement a better fix later.  However this should
  be ok for now.

- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather
  than from edac_mc_free().  Since edac_mc_add_mc() calls
  edac_create_sysfs_mci_device(), edac_mc_del_mc() should call
  edac_remove_sysfs_mci_device().

- Add ctl_dev field to "struct e752x_dev_info".  Then we can eliminate
  ugly switch statement from e752x_probe1().

- Remove code from e752x_probe1() that clears initial PCI bus parity
  errors.  The core EDAC module already does this.

680cbbbb0e [PATCH] EDAC: name cleanup
Perform the following name substitutions on all source files:

    sed 's/BS_MOD_STR/EDAC_MOD_STR/g'
    sed 's/bs_thread_info/edac_thread_info/g'
    sed 's/bs_thread/edac_thread/g'
    sed 's/bs_xstr/edac_xstr/g'
    sed 's/bs_str/edac_str/g'

The names that start with BS_ or bs_ are artifacts of when the code
was called "bluesmoke".

ceb2ca9cb0 [PATCH] EDAC: disable sysfs interface
- Disable the EDAC sysfs code.  The sysfs interface that EDAC presents to
  user space needs more thought, and is likely to change substantially.
  Therefore disable it for now so users don't start depending on it in its
  current form.

- Disable the default behavior of calling panic() when an uncorrectible
  error is detected (since for now, there is no sysfs interface that allows
  the user to configure this behavior).

4136cabff3 [PATCH] edac: disable a few sysfs files to avoid them becoming an ABI
Disable (via ugly #if 0's) the 3 sysfs files that I think by now we all
agree are very much wrong.  These files shouldn't become part of the ABI by
the 2.6.16 release, so I rather have this minimal patch merged to disable
them for now, the real fix can then come during the 2.6.17 devel window.

da9bb1d27b [PATCH] EDAC: core EDAC support code
This is a subset of the bluesmoke project core code, stripped of the NMI work
which isn't ready to merge and some of the "interesting" proc functionality
that needs reworking or just has no place in kernel.  It requires no core
kernel changes except the added scrub functions already posted.

The goal is to merge further functionality only after the core code is
accepted and proven in the base kernel, and only at the point the upstream
extras are really ready to merge.

From: doug thompson <norsk5@xmission.com>

  This converts EDAC to sysfs and is the final chunk neccessary before EDAC
  has a stable user space API and can be considered for submission into the
  base kernel.
