2011-02-10amd64_edac: Enable driver on F15hBorislav Petkov
Add the PCI device ids required for driver registration. Remove pvt->ctl_name and use the family descriptor directly, instead. Then, bump driver version and fixup its format. Finally, enable DRAM ECC decoding on F15h. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Adjust ECC symbol size to F15hBorislav Petkov
F15h has the same ECC symbol size options as F10h revD and later so adjust checks to that. Simplify code a bit. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Simplify scrubrate settingBorislav Petkov
Drop per-instance variable and compute min scrubrate dynamically. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Improve DRAM address mappingBorislav Petkov
Drop static tables which map the bits in F2x80 to a chip select size in favor of functions doing the mapping with some bit fiddling. Also, add F15 support. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Sanitize ->read_dram_ctl_registerBorislav Petkov
This function is relevant for F10h and higher, and it has only one callsite so drop its function pointer from the low_ops struct. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Adjust sys_addr to chip select conversion routine to F15hBorislav Petkov
F15h sys_addr to chip select mapping is almost identical to F10h's so reuse that. Rename functions on that path accordingly. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Beef up early exit reportingBorislav Petkov
Add paranoid checks for the sys address before going off and decoding it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Revamp online spare handlingBorislav Petkov
Replace per-DCT macros with smarter ones, drop hack and look for the spare rank on all chip selects on a channel. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Fix channel interleave removalBorislav Petkov
Remove the channel interleave select bit properly. See F2x110[DctSelIntLvAddr] for details. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Correct node interleaving removalBorislav Petkov
When node interleaving is enabled, a subset of the addr[14:12] bits has to be removed in order to get the normalized DCT address of the DRAM channel. The actual number of bits to remove is determined by F1x[1, 0][7C:40][IntlvEn]. Do this correctly. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Add support for interleaved region swappingBorislav Petkov
On revC3 and revE Fam10h machines and later, non-interleaved graphics framebuffer memory under the 16G mark can be swapped with a region located at the bottom of memory so that the GPU can use the interleaved region and thus two channels. Add support for that. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Unify get_error_addressBorislav Petkov
The address bits from MC4_STATUS differ only between K8 and the rest so no need for a per-family method. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Simplify decoding pathBorislav Petkov
Use the struct mce directly instead of copying from it into a custom struct err_regs. No functionality change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Adjust channel counting to F15hBorislav Petkov
The only difference is that F10h used to sport ganged DCTs and F15h doesn't so adjust the F10h routine and reuse it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup old defines cruftBorislav Petkov
Remove unused defines, drop family names from define names. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup NBSH cruftBorislav Petkov
Remove reporting of errors with UC bit set - this is done by the MCE decoding code anyway and this driver deals with DRAM ECC errors only. UC (NB uncorrectable error) doesn't necessarily mean it is a DRAM error. Remove unused macros while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup NBCFG handlingBorislav Petkov
The fact whether we are chipkill capable or not does not have any bearing when computing the channel index on a ganged DCT configuration so remove that. Also, simplify debug statements. Finally, remove old error injection leftovers, while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup NBCTL codeBorislav Petkov
Remove family names from macro names, drop single bit defines and comment their meaning instead. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup DCT Select Low/High codeBorislav Petkov
Shorten macro names, remove family name from macros, fix macro arguments, shorten debug strings. No functionality change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup Dram Configuration registers handlingBorislav Petkov
* Restrict DCT ganged mode check since only Fam10h supports it * Adjust DRAM type detection for BD since it only supports DDR3 * Remove second and thus unneeded DCLR read in k8_early_channel_count() - we do that in read_mc_regs() * Cleanup comments and remove family names from register macros * Remove unused defines There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup DBAM handlingBorislav Petkov
Do not read DBAM regs twice and simplify code around them. There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Replace huge bitmasks with a macroBorislav Petkov
Replace hard to read hex constants with a continuous masks macro. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Sanitize f10_get_base_addr_offsetBorislav Petkov
This function maps the system address to the normalized DCT address. Document what the code does for more clarity and wrap insane bitmasks in a more understandable macro which generates them. Also, reduce number of arguments passed to the function. Finally, rename this function to what it actually does. No functional change. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Sanitize channel extractionBorislav Petkov
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>
2011-02-10amd64_edac: Cleanup chipselect handlingBorislav Petkov
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. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Cleanup DHAR handlingBorislav Petkov
Adjust to F15h, simplify code, fixup macros. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10amd64_edac: Remove DRAM base/limit subfields cachingBorislav Petkov
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>
2011-02-10amd64_edac: Add support for F15h DCT PCI config accessesBorislav Petkov
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. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2011-02-10EDAC: Shut up sysfs registration debug codeBorislav Petkov
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>
2011-02-10amd64_edac: Fix DIMMs per DCTs outputBorislav Petkov
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 Juhl
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.
