* edac: i5000_edac critical fix panic out of boundsTamas Vincze2010-01-161-1/+7
| | | | | | | | | | | | | | | | | | EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4) Kernel panic - not syncing: EDAC MC0: Uncorrected Error (XEN) Domain 0 crashed: 'noreboot' set - not rebooting. This happens because FERR_NF_FBD bit 28 is not updated on i5000. Due to that, both bits 28 and 29 may be equal to one, returning channel = 3. As this value is invalid, EDAC core generates the panic.

* edac: i5100 fix initialization codeKeith Mannthey2009-10-291-3/+4
| | | | | | | | | | | | | | | | Allow csrows to properly initialize when the topology only has active channels on 2 and 3. This new check allows proper detection and initialization in this topology. Only checking the first mrt that represented channels 0 and 1 is not sufficient. I also fixed up the related debug information path. I can submit as a 2nd patch if needed.

* i5000-edac: hold reference to mci kobjectDarrick J. Wong2008-11-121-1/+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 i5000: fix thermal issuesAristeu Rozanski2008-10-161-1/+16
| | | | | | | | | | | | | | | | | | 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 i5000: fix error messagesAristeu Rozanski2008-10-161-62/+119
| | | | | | | | | | | | | | | Update the i5000_edac messages, making everything pass through the EDAC (so the log controls will work) and being more specific about the errors. Also, it makes the miscellaneous errors optional and disabled by default. As I didn't found anywhere information about M23ERR-M26ERR (FERR_NF_THERMAL) on FERR_NF_FBD, I'm removing them.

* edac: fix module initialization on several modules 2nd timeHitoshi Mitake2008-04-291-10/+4
| | | | | | | | | | | | | | | | | | | | | I implemented opstate_init() as a inline function in linux/edac.h. added calling opstate_init() to: i82443bxgx_edac.c i82860_edac.c i82875p_edac.c i82975x_edac.c I wrote a fixed patch of edac-fix-module-initialization-on-several-modules.patch, and tested building 2.6.25-rc7 with applying this. It was succeed. I think the patch is now correct.

* drivers/edac: fix edac_mc init apisDoug Thompson2007-07-191-4/+2
| | | | | | | | | | | | | | | | Refactoring of sysfs code necessitated the refactoring of the edac_mc_alloc() and edac_mc_add_mc() apis, of moving the index value to the alloc() function. This patch alters the in tree drivers to utilize this new api signature. Having the index value performed later created a chicken-and-the-egg issue. Moving it to the alloc() function allows for creating the necessary sysfs entries with the proper index number Cc: Alan Cox alan@lxorguk.ukuu.org.uk Signed-off-by: Doug Thompson <dougthompson@xmission.com> Cc: Greg KH <greg@kroah.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* drivers/edac: add dev_name getter functionDave Jiang2007-07-191-0/+1
| | | | | | | | | | | | | | | Move dev_name() macro to a more generic interface since it's not possible to determine whether a device is pci, platform, or of_device easily. Now each low level driver sets the name into the control structure, and the EDAC core references the control structure for the information. Better abstraction.

* drivers/edac: add new nmi rescanDave Jiang2007-07-191-0/+13
| | | | | | | | | | | | | | | | | | | Provides a way for NMI reported errors on x86 to notify the EDAC subsystem pending ECC errors by writing to a software state variable. Here's the reworked patch. I added an EDAC stub to the kernel so we can have variables that are in the kernel even if EDAC is a module. I also implemented the idea of using the chip driver to select error detection mode via module parameter and eliminate the kernel compile option. Please review/test. Thx! Also, I only made changes to some of the chipset drivers since I am unfamiliar with the other ones. We can add similar changes as we go.
