2011-03-17amd64_edac: Sanitize channel extractionBorislav Petkov1-50/+34
Cleanup and simplify f10_determine_channel(); make it more readable. Also drop f10_map_intlv_en_to_shift() in favor of simply counting the bits in F1x124[DramIntlvEn] which is equivalent. There should be no functionality change resulting from this patch. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Cleanup chipselect handlingBorislav Petkov2-238/+136
Add a struct representing the DRAM chip select base/limit register pairs. Concentrate all CS handling in a single function. Also, add CS looping macros for cleaner, more readable code. While at it, adjust code to F15h. Finally, do smaller macro names cleanups (remove family names from register macros) and debug messages clarification. No functional change.

2011-03-17amd64_edac: Cleanup DHAR handlingBorislav Petkov2-24/+23

2011-03-17amd64_edac: Remove DRAM base/limit subfields cachingBorislav Petkov2-188/+115
Add a struct representing the DRAM base/limit range pairs and remove all cached subfields. Replace them with accessor functions, which actually saves us some space: text data bss dec hex filename 14712 1577 336 16625 40f1 drivers/edac/amd64_edac_mod.o.after 14831 1609 336 16776 4188 drivers/edac/amd64_edac_mod.o.before Also, it simplifies the code a lot allowing to merge the K8 and F10h routines. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-17amd64_edac: Add support for F15h DCT PCI config accessesBorislav Petkov3-75/+146
F15h "multiplexes" between the configuration space of the two DRAM controllers by toggling D18F1x10C[DctCfgSel] while F10h has a different set of registers for DCT0, and DCT1 in extended PCI config space. Add DCT configuration space accessors per family thus wrapping all the different access prerequisites. Clean up code while at it, shorten names.

2011-03-17EDAC: Shut up sysfs registration debug codeBorislav Petkov1-13/+13
Raise the debug level of these routines so that their output get issued out only when the highest debug level is selected. Otherwise, don't pollute driver debug output. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-03-10drivers/edac: provide support for tile architectureChris Metcalf3-1/+264

2011-02-10amd64_edac: Fix DIMMs per DCTs outputBorislav Petkov1-20/+8
amd64_debug_display_dimm_sizes() reports the distribution of the DIMMs on each DRAM controller and its chip select sizes. Thus, the last don't have anything to do with whether we're running in ganged DCT mode or not - their sizes don't change all of a sudden. Fix that by removing the ganged-check and dump DCT0's config for DCT1 when in ganged mode since they're identical.

2011-01-19Kill off warning: ‘inline’ is not at beginning of declarationJesper Juhl1-1/+1
Fix a bunch of warning: ‘inline’ is not at beginning of declaration messages when building a 'make allyesconfig' kernel with -Wextra. These warnings are trivial to kill, yet rather annoying when building with -Wextra. The more we can cut down on pointless crap like this the better (IMHO). A previous patch to do this for a 'allnoconfig' build has already been merged. This just takes the cleanup a little further.

2011-01-07amd64_edac: Disable DRAM ECC injection on K8Borislav Petkov1-2/+3

2011-01-07EDAC: Fixup scrubrate manipulationBorislav Petkov7-63/+52
Make the ->{get|set}_sdram_scrub_rate return the actual scrub rate bandwidth it succeeded setting and remove superfluous arg pointer used for that.

2011-01-07amd64_edac: Remove two-stage initializationBorislav Petkov1-100/+68
Now that all prerequisites are in place, drop the two-stage driver instances initialization in favor of the following simple init sequence: 1. Probe PCI device: we only test ECC capabilities here and if none exit early. 2. If the hw supports ECC and it is/can be enabled, we init the per-node instance. Remove "amd64_" prefix from static functions touched, while at it. There actually should be no visible functional change resulting from this patch.

2011-01-07amd64_edac: Check ECC capabilities initiallyBorislav Petkov1-66/+75
Rework the code to check the hardware ECC capabilities at PCI probing time. We do all further initialization only if we actually can/have ECC enabled. While at it: 0. Fix function naming. 1. Simplify/clarify debug output. 2. Remove amd64_ prefix from the static functions 3. Reorganize code. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-01-07amd64_edac: Carve out ECC-related hw settingsBorislav Petkov2-24/+49
This is in preparation for the init path reorganization where we want only to 1) test whether a particular node supports ECC 2) can it be enabled and only then do the necessary allocation/initialization. For that, we need to decouple the ECC settings of the node from the instance's descriptor. The should be no functional change introduced by this patch.
