* drivers/edac: fix edac_mc sysfs completion codeDoug Thompson2007-07-191-16/+16
| | | | | | | | | | | | | | | | | This patch refactors the 'releasing' of kobjects for the edac_mc type of device. The correct pattern of kobject release is followed. As internal kobjs are allocated they bump a ref count on the top level kobj. It in turn has a module ref count on the edac_core module. When internal kobjects are released, they dec the ref count on the top level kobj. When the top level kobj reaches zero, it decrements the ref count on the edac_core object, allow it to be unloaded, as all resources have all now been released.

* drivers/edac: cleanup spaces-gotos after Lindent messupDouglas Thompson2007-07-191-5/+5
| | | | | | | | | | | 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.

* drivers/edac: mod use edac_core.hDouglas Thompson2007-07-191-2/+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".

* drivers/edac: add new nmi rescanDave Jiang2007-07-191-2/+22
| | | | | | | | | | | | | | | | | | | 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.

* drivers/edac: add edac_device classDouglas Thompson2007-07-191-9/+138
| | | | | | | | | | | | | | | | | | | | | | | 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.

* drivers/edac: split out functions to unique filesDouglas Thompson2007-07-191-0/+130
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'.
