* EDAC: Cleanup atomic_scrub messBorislav Petkov2015-05-281-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So first of all, this atomic_scrub() function's naming is bad. It looks like an atomic_t helper. Change it to edac_atomic_scrub(). The bigger problem is that this function is arch-specific and every new arch which doesn't necessarily need that functionality still needs to define it, otherwise EDAC doesn't compile. So instead of doing that and including arch-specific headers, have each arch define an EDAC_ATOMIC_SCRUB symbol which can be used in edac_mc.c for ifdeffery. Much cleaner. And we already are doing this with another symbol - EDAC_SUPPORT. This is also much cleaner than having CONFIG_EDAC enumerate all the arches which need/have EDAC support and drivers. This way I can kill the useless edac.h header in tile too.

With regards to ghes-edac, this fixes a longstanding BZ at Red Hat that happens with Nehalem and Sandy Bridge CPUs: when both GHES and i7core_edac or sb_edac are running, the error reports are unpredictable, as both BIOS and OS race to access the registers.

* edac: add a new per-dimm API and make the old per-virtual-rank API obsoleteMauro Carvalho Chehab2012-06-111-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old EDAC API is broken. It only works fine for systems manufatured before 2005 and for AMD 64. The reason is that it forces all memory controller drivers to discover rank info. Also, it doesn't allow grouping the several ranks into a DIMM. So, what almost all modern drivers do is to create a fake virtual-rank information, and use it to cheat the EDAC core to accept the driver. While this works if the user has enough time to discover what DIMM slot corresponds to each "virtual-rank" information, it prevents EDAC usage for users with less available time. It also makes life hard for vendors that may want to provide a table with their motherboards to the userspace tool (edac-utils) as each driver has its own logic for the virtual mapping. So, the old API should be removed, in favor of a more flexible API that allows newer drivers to not lie to the EDAC core.

* edac: Only build sb_edac on 64-bitJosh Boyer2011-11-031-1/+1
| | | | | | | | | | The sb_edac driver is marginally useful on a 32-bit kernel, and currently has 64-bit divide compile errors when building that config. For now, make this build on only for 64-bit kernels.

* x86: EDAC: carve out AMD MCE decoding logicBorislav Petkov2009-10-021-1/+13

This, beyond being separated in a cleaner way, also saves RAM by making the decoding logic modular.
