EDAC/amd64: Issue probing messages only on properly detected hardware

2021-01-22T10:13:47Z

amd64_edac was converted to CPU family autoprobing (from PCI device IDs) to not have to add a new PCI device ID each time a new platform is shipped but to support the whole family out-of-the-box. However, this caused a lot of noise in dmesg even when the machine doesn't have ECC DIMMs or ECC has been disabled in the BIOS: EDAC MC: Ver: 3.0.0 EDAC amd64: F17h detected (node 0). EDAC amd64: Node 0: DRAM ECC disabled. EDAC amd64: F17h detected (node 1). EDAC amd64: Node 1: DRAM ECC disabled. EDAC amd64: F17h detected (node 2). EDAC amd64: Node 2: DRAM ECC disabled. EDAC amd64: F17h detected (node 3). EDAC amd64: Node 3: DRAM ECC disabled. EDAC amd64: F17h detected (node 4). EDAC amd64: Node 4: DRAM ECC disabled. EDAC amd64: F17h detected (node 5). EDAC amd64: Node 5: DRAM ECC disabled. EDAC amd64: F17h detected (node 6). EDAC amd64: Node 6: DRAM ECC disabled. EDAC amd64: F17h detected (node 7). EDAC amd64: Node 7: DRAM ECC disabled. or even $ grep EDAC dmesg.log | sed 's/\[.*\] //' | sort | uniq -c 128 EDAC amd64: F17h detected (node 0). 128 EDAC amd64: Node 0: DRAM ECC disabled. 1 EDAC MC: Ver: 3.0.0 on a big machine. Yap, that's once per CPU for 128 of them. So move the init messages after all probing has succeeded to avoid unnecessary spew in dmesg.

EDAC/xgene: Do not print a failure message to get an IRQ twice

2021-01-19T09:22:23Z

Coccinelle reports a redundant error print in xgene_edac_probe() because platform_get_irq() will already print an error message when it is unable to get an IRQ. Use platform_get_irq_optional() instead which avoids the error message and keep the driver-specific one.

EDAC/amd64: Limit error injection functionality to supported hw

2020-12-28T18:36:37Z

Families up to and including 0x16 allow access to the injection hardware. Starting with family 0x17, access to those registers is blocked by security policy. Limit that only on the families which support it. Suggested-by: Yazen Ghannam Signed-off-by: Borislav Petkov Link: https://lkml.kernel.org/r/20201222180013.GD13463@zn.tnic

EDAC/amd64: Merge error injection sysfs facilities

2020-12-28T18:36:25Z

Merge them into the main driver and put them inside an EDAC_DEBUG ifdeffery to simplify the driver and have all debugging/injection stuff behind a debug build-time switch. No functional changes.

EDAC/amd64: Merge sysfs debugging attributes setup code

2020-12-28T18:36:17Z

There's no need for them to be in a separate file so merge them into the main driver compilation unit like the other EDAC drivers do. Drop now-unneeded function export, make the function static and shorten static function names. No functional changes.

EDAC/amd64: Tone down messages about missing PCI IDs

2020-12-28T18:18:03Z

Give these messages a debug severity as they are really only useful to the module developers. Also, drop the "(broken BIOS?)" phrase, since this can cause churn for BIOS folks. The PCI IDs needed by the module, at least on modern systems, are fixed in hardware.

EDAC/amd64: Do not load on family 0x15, model 0x13

2020-12-28T11:18:11Z

Those were only laptops and are very very unlikely to have ECC memory. Currently, when the driver attempts to load, it issues: EDAC amd64: Error: F1 not found: device 0x1601 (broken BIOS?) because the PCI device is the wrong one (it uses the F15h default one). So do not load the driver on them as that is pointless.
