2010-10-21EDAC, MCE: Complete NB MCE decodersBorislav Petkov
Add support for decoding F14h BU MCEs and improve decoding of the remaining families. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-10-21EDAC, MCE: Rename filesBorislav Petkov
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 Petkov
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>
2010-08-03amd64_edac: Remove unneeded definesBorislav Petkov
All F2x110-related bit defines are used at only one place so replace them with simple BIT() macros. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Acked-by: Doug Thompson <dougthompson@xmission.com>
2010-08-03amd64_edac: Sanitize syndrome extractionBorislav Petkov
Remove the two syndrome extraction macros and add a single function which does the same thing but with proper typechecking. While at it, make sure to cache ECC syndrome size and dump it in debug output. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2010-03-01amd64_edac: Simplify ECC override handlingBorislav Petkov
No need for clearing ecc_enable_override and checking it in two places. Instead, simply check it during probing and act accordingly. Also, rename the flag bitfields according to the functionality they actually represent. What is more, make sure original BIOS ECC settings are restored when the module is unloaded. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-08amd64_edac: bump driver versionBorislav Petkov
This was long overdue ... Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: remove early hw support checkBorislav Petkov
The .probe_valid_hardware low_ops member checked whether the DCTs are in DDR3 mode and bailed out if so. Now that all the needed changes for DDR3 support is in place, remove it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: enhance address to DRAM bank mappingBorislav Petkov
Add cs mode to cs size mapping tables for DDR2 and DDR3 and F10 and all K8 flavors and remove klugdy table of pseudo values. Add a low_ops->dbam_to_cs member which is family-specific and replaces low_ops->dbam_map_to_pages since the pages calculation is a one liner now. Further cleanups, while at it: - shorten family name defines - align amd64_family_types struct members Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: cleanup DRAM cfg low debug outputBorislav Petkov
Carve out the register-specific debug statements into a separate function, clarify meanings of the single bitfields in the register, remove irrelevant output and macros. There should be no functionality change resulting from this patch. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: wrap-up pci config read error handlingBorislav Petkov
Add a pci config read wrapper for signaling pci config space access errors instead of them being visible only on a debug build. This is important on amd64_edac since it uses all those pci config register values to access the DRAM/DIMM configuration of the nodes. In addition, the wrapper makes a _lot_ (look at the diffstat!) of error handling code superfluous and improves much of the overall code readability by removing error handling details out of the way. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-12-07amd64_edac: unify MCGCTL ECC switchingBorislav Petkov
Unify almost identical code into one function and remove NUMA-specific usage (specifically cpumask_of_node()) in favor of generic topology methods. Remove unused defines, while at it. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-10-07amd64_edac: beef up DRAM error injectionBorislav Petkov
When injecting DRAM ECC errors (F3xBC_x8), EccVector[15:0] is a bitmask of which bits should be error injected when written to and holds the payload of 16-bit DRAM word when read, respectively. Add /sysfs members to show the DRAM ECC section/word/vector. Fail wrong injection values entered over /sysfs instead of truncating them. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-10-07amd64_edac: fix chip select handlingBorislav Petkov
Different processor families support a different number of chip selects. Handle this in a family-dependent way with the proper values assigned at init time (see amd64_set_dct_base_and_mask). Remove _DCSM_COUNT defines since they're used at one place and originate from public documentation. CC: Keith Mannthey <kmannth@us.ibm.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-10-07amd64_edac: fix driver instance lookup table allocationBorislav Petkov
Allocate memory statically for 8-node machines max for simplicity instead of relying on MAX_NUMNODES which is 0 on !CONFIG_NUMA builds. Spotted by Jan Beulich. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14x86, mce: pass mce info to EDAC for decodingBorislav Petkov
Move NB decoder along with required defines to EDAC MCE core. Add registration routines for further decoding of the MCE info in the AMD64 EDAC module. CC: Andi Kleen <andi@firstfloor.org> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14amd64_edac: cleanup/complete NB MCE decodingBorislav Petkov
* don't dump info which mcheck already does * update to newest BKDG * mv amd64_process_error_info -> amd64_decode_nb_mce * shorten error struct names * remove redundant info ptr in amd64_process_error_info * remove unused ErrorCodeExt[19:16] (MCx_STATUS) defines Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14amd64_edac: cleanup amd64_process_error_infoBorislav Petkov
* mv amd64_error_info_regs -> err_regs * remove redundant info ptr Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-09-14EDAC: move MCE error descriptions to EDAC coreBorislav Petkov
This is in preparation of adding AMD-specific MCE decoding functionality to the EDAC core. The error decoding macros originate from the AMD64 EDAC driver albeit in a simplified and cleaned up version here. While at it, add macros to generate the error description strings and use them in the error type decoders directly which removes a bunch of code and makes the decoding functions much more readable. Also, fix strings and shorten macro names. Remove superfluous htlink_msgs. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-06-26amd64_edac: misc small cleanupsBorislav Petkov
- cleanup debug calls - shorten function names - cleanup error exit paths Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-06-10amd64_edac: add module registration routinesDoug Thompson
Also, link into Kbuild by adding Kconfig and Makefile entries. Borislav: - Kconfig/Makefile splitting - use zero-sized arrays for the sysfs attrs if not enabled - rename sysfs attrs to more conform values - shorten CONFIG_ names - make multiple structure members assignment vertically aligned - fix/cleanup comments - fix function return value patterns - fix err labels - fix a memleak bug caught by Ingo - remove the NUMA dependency and use num_k8_northbrides for initializing a driver instance per NB. - do not copy the pvt contents into the mci struct in amd64_init_2nd_stage() and save it in the mci->pvt_info void ptr instead. - cleanup debug calls - simplify amd64_setup_pci_device() Reviewed-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
2009-06-10amd64_edac: add ECC reporting initializersDoug Thompson
Borislav: - convert to the new {rd|wr}msr_on_cpus interfaces. - convert pvt->old_mcgctl to a bitmask thus saving some bytes - fix/cleanup comments - fix function return value patterns - add a proper bugfix found by Doug to amd64_check_ecc_enabled where we missed checking for the ECC enabled bit in NB CFG. - cleanup debug calls Reviewed-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Doug Thompson <dougthompson@xmission.com> Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
