Compiling this module gave a warning that the return value of 'pci_bus_add_device()' was not checked. This patch adds that check and an output message Signed-off-by:

If ERRSTS indicates that there's no error then we don't need to bother reading the other registers. In addition to making the common case faster, this actually fixes a small race where we don't see an error but we clear the error bits anyway, potentially wiping away info on an error that happened in the interim (or where a CE arrives between the first and second read of ERRSTS, causing us to falsely claim "UE overwrote CE").

1) Remove an old CVS ID string 2) change EDAC from a tristate option to a simple bool option 3) In addition to the X86 arch, PPC and MIPS also have drivers in the submission queue. This patch turns on the EDAC flag for those archs. Each driver will have its respective 'depends on ARCH' set. Signed-off-by:

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. Signed-off-by:

Added new controls for the edac_device and edac_mc sysfs folder. These can be initialized by the low level driver to provide misc controls into the low level driver for its use Signed-off-by:

The origin of this code comes from patches at sourceforge, that allow EDAC to be updated to various kernels. With kernel version 2.6.20 a new workq system was installed, thus the patches needed to be modified based on the kernel version. For submitting to the latest kernel.org those #ifdefs are removed Signed-off-by:

Here's a driver for the Intel 3000 and 3010 memory controllers, relative to today's Sourceforge code drop. This has only had light testing (I've yet to actually see it handle a memory error) but it detects my hardware correctly. Signed-off-by:

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. Signed-off-by:

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". Signed-off-by:

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. Signed-off-by:

Adding missing mem types for use in the sysfs presentation file for Memory Controller device objects. Signed-off-by:

Douglas Thompson authored
This patch adds the new 'class' of object to be managed, named: 'edac_device'. As a peer of the 'edac_mc' class of object, it provides a non-memory centric view of an ERROR DETECTING device in hardware. It provides a sysfs interface and an abstraction for varioius EDAC type devices. Multiple 'instances' within the class are possible, with each 'instance' able to have multiple 'blocks', and each 'block' having 'attributes'. At the 'block' level there are the 'ce_count' and 'ue_count' fields which the device driver can update and/or call edac_device_handle_XX() functions. At each higher level are additional 'total' count fields, which are a summation of counts below that level. This 'edac_device' has been used to capture and present ECC errors which are found in a a L1 and L2 system on a per CORE/CPU basis. Signed-off-by:

This is a large patch to refactor the original EDAC module in the kernel and to break it up into better file granularity, such that each source file contains a given subsystem of the EDAC CORE. Originally, the EDAC 'core' was contained in one source file: edac_mc.c with it corresponding edac_mc.h file. Now, there are the following files: edac_module.c The main module init/exit function and other overhead edac_mc.c Code handling the edac_mc class of object edac_mc_sysfs.c Code handling for sysfs presentation edac_pci_sysfs.c Code handling for PCI sysfs presentation edac_core.h CORE .h include file for 'edac_mc' and 'edac_device' drivers edac_module.h Internal CORE .h include file This forms a foundation upon which a later patch can create the 'edac_device' class of object code in a new file 'edac_device.c'.
