git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac Pull EDAC fixes and ghes-edac from Mauro Carvalho Chehab: "For: - Some fixes at edac drivers (i7core_edac, sb_edac, i3200_edac); - error injection support for i5100, when EDAC debug is enabled; - fix edac when it is loaded builtin (early init for the subsystem); - a "Firmware First" EDAC driver, allowing ghes to report errors via EDAC (ghes-edac). 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. With ghes-edac, the EDAC core will refuse to register any other concurrent memory error driver. This patchset moves the ghes struct definitions to a separate header file (include/acpi/ghes.h) and adds 3 hooks at apei/ghes.c to register/unregister and to report errors via ghes-edac.

2013-02-25ghes_edac: Register at EDAC core the BIOS reportMauro Carvalho Chehab1-0/+23
Register GHES at EDAC MC core, in order to avoid other drivers to also handle errors and mangle with error data. The edac core will warrant that just one driver will be used, so the first one to register (BIOS first) will be the one that will be reporting the hardware errors. For now, the EDAC driver does nothing but to register at the EDAC core, preventing the hardware-driven mechanism to interfere with GHES. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-01-07EDAC: Fix EDAC Kconfig menuBorislav Petkov1-5/+3
After f65aad41772f("MIPS: Cavium: Add EDAC support."), when entering the "Device Drivers" toplevel menu in menuconfig, the suboptions behind EDAC appeared merged with the rest of the device drivers types. This was because the menuconfig option EDAC is querying an EDAC_SUPPORT Kconfig bool which was defined after the menu definition. When pushing EDAC_SUPPORT up, before the menu definition, the variable is defined earlier and the above menuconfig artifact doesn't happen. Drop a useless menuconfig comment while at it.

2012-12-12MIPS: Cavium: Add EDAC support.Ralf Baechle1-1/+32
Drivers for EDAC on Cavium. Supported subsystems are: o CPU primary caches. These are parity protected only, so only error reporting. o Second level cache - ECC protected, provides SECDED. o Memory: ECC / SECDEC if used with suitable DRAM modules. The driver will will only initialize if ECC is enabled on a system so is safe to run on non-ECC memory. o PCI: Parity error reporting Since it is very hard to test this sort of code the implementation is very conservative and uses polling where possible for now.

2012-06-11edac: add a new per-dimm API and make the old per-virtual-rank API obsoleteMauro Carvalho Chehab1-0/+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.

2010-05-10edac_mce: Add an interface driver to report mce errors via edacMauro Carvalho Chehab1-1/+7
edac_mce module is an interface module that gets mcelog data and forwards to any registered edac module that expects to receive data via mce. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-05-10i7core_edac: Add an EDAC memory controller driver for Nehalem chipsetsMauro Carvalho Chehab1-0/+7
This driver is meant to support i7 core/i7core extreme desktop processors and Xeon 35xx/55xx series with integrated memory controller. It is likely that it can be expanded in the future to work with other processor series based at the same Memory Controller design. For now, it has just a few MCH status reads.

2009-10-02x86: EDAC: carve out AMD MCE decoding logicBorislav Petkov1-1/+13
This converts the MCE decoding logic into a standalone config option which can be built-in or a module, the first one being the default for MCEs happening early on in the boot process. This, beyond being separated in a cleaner way, also saves RAM by making the decoding logic modular.

2009-09-24edac: i3200 memory controller driverJason Uhlenkott1-0/+7
A driver for the Intel 3200 and 3210 memory controllers. It has only had light testing so far, and currently makes no attempt to decode error addresses at anything finer than csrow granularity.

2009-09-24edac: mpc85xx add mpc83xx supportIra W. Snyder1-3/+3
Add support for the Freescale MPC83xx memory controller to the existing driver for the Freescale MPC85xx memory controller. The only difference between the two processors are in the CS_BNDS register parsing code, which has been changed so it will work on both processors. The L2 cache controller does not exist on the MPC83xx, but the OF subsystem will not use the driver if the device is not present in the OF device tree. I had to change the nr_pages calculation to make the math work out. I checked it on my board and did the math by hand for a 64GB 85xx using 64K pages. In both cases, nr_pages * PAGE_SIZE comes out to the correct value. Signed-off-by: Ira W.
