edac: add CPC925 Memory Controller driver

2009-06-18T20:03:56+00:00

Introduce IBM CPC925 EDAC driver, which makes use of ECC, CPU and
HyperTransport Link error detections and corrections on the IBM
CPC925 Bridge and Memory Controller.

amd64_edac: add module registration routines

2009-06-10T10:19:28+00:00

Also, link into Kbuild by adding Kconfig and Makefile entries.

Borislav:
- Kconfig/Makefile splitting
- use zero-sized arrays for the sysfs attrs if not enabled
- rename sysfs attrs to more conform values
- shorten CONFIG_ names
- make multiple structure members assignment vertically aligned
- fix/cleanup comments
- fix function return value patterns
- fix err labels
- fix a memleak bug caught by Ingo
- remove the NUMA dependency and use num_k8_northbrides for initializing
  a driver instance per NB.
- do not copy the pvt contents into the mci struct in
  amd64_init_2nd_stage() and save it in the mci->pvt_info void ptr
  instead.
- cleanup debug calls
- simplify amd64_setup_pci_device()

edac: AMD8111 & AMD8131 Kconfig fixup

2009-05-29T15:40:03+00:00

The amd8111_edac.c driver will fail allmodconfig on architectures other
than PPC, introduce Kconfig dependency to avoid this, since both AMD8111
and AMD8131 chips are only adopted on Maple so far.

edac: new ppc4xx driver module

2009-04-03T02:05:03+00:00

This adds support for an EDAC memory controller adaptation driver for the
"ibm,sdram-4xx-ddr2" ECC controller realized in the AMCC PowerPC 405EX[r].

At present, this driver has been developed and tested against the
controller realization in the AMCC PPC405EX[r] on the AMCC Kilauea and
Haleakala boards (256 MiB w/o ECC memory soldered onto the board) and a
proprietary board based on those designs (128 MiB ECC memory, also
soldered onto the board).

In the future, dynamic feature detection and handling needs to be added
for the other realizations of this controller found in the 440SP, 440SPe,
460EX, 460GT and 460SX.

Eventually, this driver will likely be evolved and adapted to the above
variant realizations of this controller as well as broken apart to handle
the other known ECC-capable controllers prevalent in other PPC4xx
processors:

  - IBM SDRAM (405GP, 405CR and 405EP) "ibm,sdram-4xx"
  - IBM DDR1 (440GP, 440GX, 440EP and 440GR) "ibm,sdram-4xx-ddr"
  - Denali DDR1/DDR2 (440EPX and 440GRX) "denali,sdram-4xx-ddr2"

edac x38: new MC driver module

2008-10-30T18:38:45+00:00

I wrote a new module for Intel X38 chipset.  This chipset is very similar
to Intel 3200 chipset, but there are some different points, so I copyed
i3200_edac.c and modified.

This is Intel's web page describing this chipset.
http://www.intel.com/Products/Desktop/Chipsets/X38/X38-overview.htm

I've tested this new module with broken memory, and it seems to be working
well.

edac: i5100 new intel chipset driver

2008-07-25T17:53:48+00:00

Preliminary support for the Intel 5100 MCH.  CE and UE errors are reported
along with the current DIMM label information and other memory parameters.

Reasons why this is preliminary:

1) This chip has 2 independent memory controllers which, for best
   perforance, use interleaved accesses to the DDR2 memory.  This
   architecture does not map very well to the current edac data structures
   which depend on symmetric channel access to the interleaved data.
   Without core changes, the best I could do for now is to map both memory
   controllers to different csrows (first all ranks of controller 0, then
   all ranks of controller 1).  Someone much more familiar with the edac
   core than I will probably need to come up with a more general data
   structure to handle the interleaving and de-interleaving of the two
   memory controllers.

2) I have not yet tackled the de-interleaving of the rank/controller
   address space into the physical address space of the CPU.  There is
   nothing fundamentally missing, it is just ending up to be a lot of
   code, and I'd rather keep it separate for now, esp since it doesn't
   work yet...

3) The code depends on a particular i5100 chip select to DIMM mainboard
   chip select mapping.  This mapping seems obvious to me in order to
   support dual and single ranked memory, but it is not unique and DIMM
   labels could be wrong on other mainboards.  There is no way to query
   this mapping that I know of.

4) The code requires that the i5100 is in 32GB mode.  Only 4 ranks per
   controller, 2 ranks per DIMM are supported.  I do not have hardware
   (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks
   per controller) mode.

5) The serial presence detect code should be broken out into a "real"
   i2c driver so that decode-dimms.pl can work.

drivers-edac: add Cell MC driver

2008-02-07T16:42:23+00:00

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.
