2016-11-28EDAC, amd64: Read MC registers on AMD Fam17hYazen Ghannam1-0/+13
Fam17h has a different set of registers and bitfields. Most of these registers are read through SMN (System Management Network) rather than PCI config space.

2015-09-29EDAC, amd64_edac: Extend scrub rate support to F15hM60hAravind Gopalakrishnan1-0/+2
The scrub rate control register has moved to function 2 in PCI config space and is at a different offset on family 0x15, models 0x60 and later. The minimum recommended scrub rate has also changed. (Refer to D18F2x1c9_dct[1:0][DramScrub] in Fam15hM60h BKDG). Adjust set_scrub_rate() and get_scrub_rate() functions to accommodate this. Tested on F15hM60h, Fam15h, models 00h-0fh and Fam10h systems.

2014-10-30amd64_edac: Add F15h M60h supportAravind Gopalakrishnan1-3/+12
This patch adds support for ECC error decoding for F15h M60h processor. Aside from the usual changes, the patch adds support for some new features in the processor: - DDR4(unbuffered, registered); LRDIMM DDR3 support - relevant debug messages have been modified/added to report these memory types - new dbam_to_cs mappers - if (F15h M60h && LRDIMM); we need a 'multiplier' value to find cs_size. This multiplier value is obtained from the per-dimm DCSM register. So, change the interface to accept a 'cs_mask_nr' value to facilitate this calculation - switch-casing determine_memory_type() - done to cleanse the function of too many if-else statements and improve readability - This is now called early in read_mc_regs() to cache dram_type Misc cleanup: - amd64_pci_table[] is condensed by using PCI_VDEVICE macro. Testing details: Tested the patch by injecting 'ECC' type errors using mce_amd_inj and error decoding works fine.

2014-09-23amd64_edac: Modify usage of amd64_read_dct_pci_cfg()Aravind Gopalakrishnan1-5/+0
Rationale behind this change: - F2x1xx addresses were stopped from being mapped explicitly to DCT1 from F15h (OR) onwards. They use _dct[0:1] mechanism to access the registers. So we should move away from using address ranges to select DCT for these families. - On newer processors, the address ranges used to indicate DCT1 (0x140, 0x1a0) have different meanings than what is assumed currently. Changes introduced: - amd64_read_dct_pci_cfg() now takes in dct value and uses it for 'selecting the dct' - Update usage of the function. Keep in mind that different families have specific handling requirements - Remove [k8|f10]_read_dct_pci_cfg() as they don't do much different from amd64_read_pci_cfg() - Move the k8 specific check to amd64_read_pci_cfg - Remove f15_read_dct_pci_cfg() and move logic to amd64_read_dct_pci_cfg() - Remove now needless .read_dct_pci_cfg Testing: - Tested on Fam 10h; Fam15h Models: 00h, 30h; Fam16h using 'EDAC_DEBUG' and mce_amd_inj - driver obtains info from F2x registers and caches it in pvt structures correctly - ECC decoding works fine Signed-off-by: Aravind Gopalakrishnan <aravind.gopalakrishnan@amd.com> Link: http://lkml.kernel.org/r/1410799058-3149-1-git-send-email-aravind.gopalakrishnan@amd.com Signed-off-by: Borislav Petkov <bp@suse.de>

2013-08-12amd64_edac: Add ECC decoding support for newer F15h modelsAravind Gopalakrishnan1-4/+54
On newer models, support has been included for upto 4 DCT's, however, only DCT0 and DCT3 are currently configured (cf BKDG Section 2.10). Also, the routing DRAM Requests algorithm is different for F15h M30h. Thus it is cleaner to use a brand new function rather than adding quirks to the more generic f1x_match_to_this_node(). Refer to "2.10.5 DRAM Routing Requests" in the BKDG for further info. Tested on Fam15h M30h with ECC turned on using mce_amd_inj facility and verified to be functionally correct. While at it, verify if erratum workarounds for E505 and E637 still hold. From email conversations within AMD, the current status of the errata is: * Erratum 505: fixed in model 0x1, stepping 0x1 and later. * Erratum 637: not fixed.
