* i5000-edac: hold reference to mci kobjectDarrick J. Wong2008-11-131-1/+3
| | | | | | | | | | | | | | | It turns out that edac_mc_del_mc will kobject_put the last kref on the mci object. If the timing is just right, that means that the mci object is freed before before i5000_remove_one has a chance to free the resources associated with it, causing a null pointer exceptions when unloading the driver. Insert a kobject_{get,put} pair so that this doesn't happen. Signed-off-by: Darrick J.

* edac x38: new MC driver moduleHitoshi Mitake2008-10-303-0/+532
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Make the Thermal messages (temperature got past Tmid) be displayed only once because: 1) it's the BIOS job to configure and handle the memory throttling 2) if the BIOS is broken or is aware about the condition, flooding the system logs won't help anything. 3) According to the specification update for Intel 5000 MCHs, all the revisions of this MCH have problems on the thermal sensors, making not automatic (a.k.a. intelligent thermal throttling) impossible.

* edac: core fix added newline to sysfs dimm labelsArthur Jones2008-07-251-1/+5
| | | | | | | | | | | | | | | | | | | | | The channel DIMM label does not seem to be used much in the edac code. However, where it is used (in the core code), it is assumed to not have a newline embedded. This leaves the sysfs file newline free which looks funny when cat'ing it. Here we just add the trailing newline to the sysfs chX_dimm_label output... [Doug Thompson note: the DIMM label is one of the primary uses of EDAC. User space daemon scripts, edac-utils@sourceforge, populate the DIMM label fields, via /sys/devices/system/edac attributes, with the silk screen labels of the motherboard in use. dmidecode access BIOS tables, but BIOS tables are well known to be incorrect and useless in these respects. edac-utils will strip off any newlines before its use of the output, when displaying DIMM slot silk screen labels.

Here we provide a new module parameter set method to call out to the update routine.

* edac: i5100 new intel chipset driverArthur Jones2008-07-253-0/+835
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | Add a module parameter "sysbus_parity" to allow forcing system bus parity error checking on or off. Also add support to automatically disable system bus parity errors for processors which do not support it. If the sysbus_parity parameter is specified, sysbus parity detection will be forced on or off. If it is not specified, the driver will attempt to look at the CPU identifier string and determine if the CPU supports system bus parity. A blacklist was used instead of a whitelist so that system bus parity would be enabled by default and to minimize the chances of breaking things for those people already using the driver which for some reason have a processor that does not have a valid CPU identifier string.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
