AMD DDR3 ECC

AMD DDR3 ECC

[ST]

Hi

I've bought a new mainboard and i'd like to get the EDAC support running for 
this board. It seems as if my hardware is not supported but detected:
dmesg gives me after a "modprobe amd64_edac_mod":
EDAC amd64_edac:  Ver: 3.2.0 Oct  9 2009
EDAC amd64: ECC is enabled by BIOS.
EDAC MC: F10h CPU detected
EDAC amd64: f10_probe_valid_hardware() This machine is running with DDR3 
memory. This is not currently supported. DCHR0=0x3f58090d DCHR1=0x3f58090d
EDAC amd64:    Contact 'amd64_edac' module MAINTAINER to help add support.

This is with 2.6.32-rc3-00256-g36a0790. I would be thankful for any hint to 
get the HW up and running.

Thanks
ST

At this time DDR3 has not been added. We just got the driver into the kernel in 2.6.31.

I will copy boris on any planned schedule for DDR3

Yeah, it is on my TODO-list. I'll keep you posted.

ST, are you willing to test patches?

I've got the first version of patches with DDR3 support for .33 ready.
They're on my kernel.org repo (branch for-next):

git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git for-next

so if you'd like to give them a try, you can now :). I'd appreciate it
if you'd let me know of any issues you might encounter.

Thanks.
