EDAC: Delete edac_stub.c

2017-04-10T15:14:48+00:00

Move the remaining functionality to edac_mc.c. Convert "edac_report=" to a module parameter. Signed-off-by: Borislav Petkov

EDAC: Remove EDAC_MM_EDAC

2017-04-10T15:14:41+00:00

Move all the EDAC core functionality behind CONFIG_EDAC and get rid of that indirection. Update defconfigs which had it. While at it, fix dependencies such that EDAC depends on RAS for the tracepoints.

EDAC: Move edac_op_state to edac_mc.c

2017-04-10T15:14:29+00:00

... as part of moving stuff away from edac_stub.c Signed-off-by: Borislav Petkov

EDAC: Remove edac_err_assert

2017-04-10T15:14:21+00:00

... and the glue around it. It is not needed anymore. Signed-off-by: Borislav Petkov

EDAC: Get rid of edac_handlers

2017-04-10T15:14:17+00:00

Use mc_devices list instead to check whether we have EDAC driver instances successfully registered with EDAC core. Signed-off-by: Borislav Petkov

x86/nmi, EDAC: Get rid of DRAM error reporting thru PCI SERR NMI

2017-04-10T15:13:48+00:00

Apparently, some machines used to report DRAM errors through a PCI SERR NMI. This is why we have a call into EDAC in the NMI handler. See c0d121720220 ("drivers/edac: add new nmi rescan"). From looking at the patch above, that's two drivers: e752x_edac.c and e7xxx_edac.c. Now, I wanna say those are old machines which are probably decommissioned already. Tony says that "[t]the newest CPU supported by either of those drivers is the Xeon E7520 (a.k.a. "Nehalem") released in Q1'2010. Possibly some folks are still using these ... but people that hold onto h/w for 7 years generally cling to old s/w too ... so I'd guess it unlikely that we will get complaints for breaking these in upstream." So even if there is a small number still in use, we did load EDAC with edac_op_state == EDAC_OPSTATE_POLL by default (we still do, in fact) which means a default EDAC setup without any parameters supplied on the command line or otherwise would never even log the error in the NMI handler because we're polling by default: inline int edac_handler_set(void) { if (edac_op_state == EDAC_OPSTATE_POLL) return 0; return atomic_read(&edac_handlers); } So, long story short, I'd like to get rid of that nastiness called edac_stub.c and confine all the EDAC drivers solely to drivers/edac/. If we ever have to do stuff like that again, it should be notifiers we're using and not some insanity like this one. Signed-off-by: Borislav Petkov Acked-by: Thomas Gleixner Cc: Tony Luck

EDAC: Rip out the edac_subsys reference counting

2015-12-11T15:56:39+00:00

This was really dumb - reference counting for the main EDAC sysfs object. While we could've simply registered it as the first thing in the module init path and then hand it around to what needs it. Do that and rip out all the code around it, thus simplifying the whole handling significantly. Move the edac_subsys node back to edac_module.c. Signed-off-by: Borislav Petkov

EDAC, edac_stub: Drop arch-specific include

2015-05-29T20:01:00+00:00

contains only the arch-specific scrubbing function and is thus not needed in edac_stub.c. Kill it. Signed-off-by: Borislav Petkov

EDAC: Add an edac_report parameter to EDAC

2013-12-11T17:06:47+00:00

This new parameter is used to control how to report HW error reporting, especially for newer Intel platform, like Ivybridge-EX, which contains an enhanced error decoding functionality in the firmware, i.e. eMCA.
