2010-10-21EDAC, MCE: Add F12h DC MCE decoderBorislav Petkov1-7/+17
F12h DC MCE signatures are a subset of F10h's so reuse them. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Add support for F11h MCEsBorislav Petkov1-3/+12
F11h has almost the same MCE signatures as K8 except DRAM ECC and MC5 bank errors. Reuse functionality from the other families. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Enable MCE decoding on F14hBorislav Petkov1-4/+5
Now that all decoders have been taught about F14h, models < 0x10 MCEs, enable decoding on this family of CPUs. Also, issue a short informational message upon boot that MCE decoding gets enabled. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Fix FR MCEs decodingBorislav Petkov1-4/+10

2010-10-21EDAC, MCE: Warn about LS MCEs on F14hBorislav Petkov1-5/+13
F14h CPUs do not generate LS MCEs so exit early and warn the user in case this path is ever hit that something else might be going haywire. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Adjust IC decoders to F14hBorislav Petkov2-48/+71
Add support for IC MCEs for F14h CPUs. K8 and F10h are almost identical so use one function for both. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Adjust DC decoders to F14hBorislav Petkov2-27/+171
Add a per-family data cache decoders. Since there is a certain overlap between the different DC MCE signatures, reuse functionality between the families as far as possible. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Rename filesBorislav Petkov5-3/+4
Drop "edac_" string from the filenames since they're prefixed with edac/ in their pathname anyway. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Rework MCE injectionBorislav Petkov7-207/+203
Add sysfs injection facilities for testing of the MCE decoding code. Remove large parts of amd64_edac_dbg.c, as a result, which did only NB MCE injection anyway and the new injection code supports that functionality already. Add an injection module so that MCE decoding code in production kernels like those in RHEL and SLES can be tested. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC: Export edac sysfs class to users.Borislav Petkov6-95/+71
Move toplevel sysfs class to the stub and make it available to non-modularized code too. Add proper refcounting of its users and move the registration functionality into the reference counting routines. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Pass complete MCE info to decodersBorislav Petkov4-47/+56

2010-10-21EDAC, MCE: Add HW_ERR prefixBorislav Petkov1-17/+17

2010-10-21EDAC: Fix error returnBorislav Petkov1-1/+1

2010-09-27amd64_edac: Fix driver module removalBorislav Petkov1-0/+3
f4347553b30ec66530bfe63c84530afea3803396 removed the edac polling mechanism in favor of using a notifier chain for conveying MCE information to edac. However, the module removal path didn't test whether the driver had setup the polling function workqueue at all and the rmmod process was hanging in the kernel at try_to_del_timer_sync() in the cancel_delayed_work() path, trying to cancel an uninitialized work struct. Fix that by adding a balancing check to the workqueue removal path. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-09-24i7300_edac: Properly initialize per-csrow memory sizeMauro Carvalho Chehab1-7/+10
Due to the current edac-core limits, we cannot represent a per-channel memory size, for FB-DIMM drivers. So, we need to sum-up all values for each slot, in order to properly represent the total amount of memory found by the i7300 driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-09-24V4L/DVB: i7300_edac: better initialize page countsMauro Carvalho Chehab1-9/+9
It is still somewhat fake, as the pages may not be on this exact order, and may even be used in mirror mode, but this is a best guess than the other random fake values. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-09-20x86, k8: Rename k8.[ch] to amd_nb.[ch] and CONFIG_K8_NB to CONFIG_AMD_NBAndreas Herrmann2-2/+2
The file names are somehow misleading as the code is not specific to AMD K8 CPUs anymore. The files accomodate code for other AMD CPU northbridges as well. Same is true for the config option which is valid for AMD CPU northbridges in general and not specific to K8. Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> LKML-Reference: <20100917160343.GD4958@loge.amd.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2010-09-17x86, k8-gart: Decouple handling of garts and northbridgesAndreas Herrmann1-1/+1
So far we only provide num_k8_northbridges. This is required in different areas (e.g. L3 cache index disable, GART). But not all AMD CPUs provide a GART. Thus it is useful to split off the GART handling from the generic caching of AMD northbridge misc devices.

2010-08-30i7300_edac: Cleanup: reorganize the file contentsMauro Carvalho Chehab1-56/+60

2010-08-30i7300_edac: pre-allocate a buffer used to prepare err messagesMauro Carvalho Chehab1-17/+24
Instead of dynamically allocating a buffer for it where needed, just allocate it once. As we'll use the same buffer also during fatal and non-fatal errors, is is very risky to dynamically allocate it during an error. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-08-30i7300_edac: Cleanup: remove get_error_info logicMauro Carvalho Chehab1-36/+6
