| * EDAC/i10nm: Retrieve and print retry_rd_err_log registersYouquan Song2021-08-234-3/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Retrieve and print retry_rd_err_log registers like the earlier change: commit e80634a75aba ("EDAC, skx: Retrieve and print retry_rd_err_log registers") This is a little trickier than on Skylake because of potential interference with BIOS use of the same registers. The default behavior is to ignore these registers. A module parameter retry_rd_err_log(default=0) controls the mode of operation: - 0=off : Default. - 1=bios : Linux doesn't reset any control bits, but just reports values. This is "no harm" mode, but it may miss reporting some data. - 2=linux: Linux tries to take control and resets mode bits, clears valid/UC bits after reading. This should be more reliable (especially if BIOS interference is reduced by disabling eMCA reporting mode in BIOS setup).

| * EDAC/i10nm: Fix NVDIMM detectionQiuxu Zhuo2021-08-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MCDDRCFG is a per-channel register and uses bit{0,1} to indicate the NVDIMM presence on DIMM slot{0,1}. Current i10nm_edac driver wrongly uses MCDDRCFG as per-DIMM register and fails to detect the NVDIMM. Fix it by reading MCDDRCFG as per-channel register and using its bit{0,1} to check whether the NVDIMM is populated on DIMM slot{0,1}.

| * EDAC/mce_amd: Do not load edac_mce_amd module on guestsSmita Koralahalli2021-08-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hypervisors likely do not expose the SMCA feature to the guest and loading this module leads to false warnings. This module should not be loaded in guests to begin with, but people tend to do so, especially when testing kernels in VMs. And then they complain about those false warnings. Do the practical thing and do not load this module when running as a guest to avoid all that complaining.

Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

This function is used in amd64_edac_mod to do system-specific decoding for DRAM ECC errors. The function takes a "NodeId" as a parameter. In AMD documentation, NodeId is used to identify a physical die in a system. This can be used to identify a node in the AMD_NB code and also it is used with umc_normaddr_to_sysaddr(). However, the input used for decode_dram_ecc() is currently the NUMA node of a logical CPU. In the default configuration, the NUMA node and physical die will be equivalent, so this doesn't have an impact. But the NUMA node configuration can be adjusted with optional memory interleaving modes. This will cause the NUMA node enumeration to not match the physical die enumeration. The mismatch will cause the address translation function to fail or report incorrect results. Use struct cpuinfo_x86.cpu_die_id for the node_id parameter to ensure the physical ID is used.

For convenience, it uses the 0th memory controller descriptor under the assumption that if any, the 0th will be always present. However, this assumption goes wrong when the 0th node doesn't have memory and the driver doesn't initialize an instance for it: EDAC amd64: F17h detected (node 0). ... EDAC amd64: Node 0: No DIMMs detected. But looking up node instances is not really needed - all one needs is the pointer to the proper device which gets discovered during instance init. So stash that pointer into a variable and use it when setting up the EDAC PCI component. Clear that variable when the driver needs to unwind due to some instances failing init to avoid any registration imbalance.
