2008-11-13i5000-edac: hold reference to mci kobjectDarrick J. Wong1-1/+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.

2008-10-16edac i5000: fix thermal issuesAristeu Rozanski1-1/+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.

2008-10-16edac i5000: fix error messagesAristeu Rozanski1-62/+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.

2008-04-29edac: fix module initialization on several modules 2nd timeHitoshi Mitake1-10/+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.

2007-11-15i5000_edac: no need to __stringify() KBUILD_BASENAMEDarrick J. Wong1-1/+1
The i5000_edac driver's PCI registration structure has the name ""i5000_edac"" (with extra set of double-quotes) which is probably not intentional. Get rid of __stringify. Signed-off-by: Darrick J.

2007-07-19drivers/edac: fix edac_mc init apisDoug Thompson1-4/+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>

2007-07-19drivers/edac: cleanup spaces-gotos after Lindent messupDouglas Thompson1-80/+80
This patch fixes some remnant spaces inserted by the use of Lindent. Seems Lindent adds some spaces when it shoulded. These have been fixed. In addition, goto targets have issues, these have been fixed in this patch.

2007-07-19drivers/edac: add dev_name getter functionDave Jiang1-0/+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.

2007-07-19drivers/edac: mod use edac_core.hDouglas Thompson1-2/+2
In the refactoring of edac_mc.c into several subsystem files, the header file edac_mc.h became meaningless. A new header file edac_core.h was created. All the files that previously included "edac_mc.h" are changed to include "edac_core.h".

2007-07-19drivers/edac: add new nmi rescanDave Jiang1-0/+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.
