Current arm64 systems that use the ghes driver lack kernel support for a proper memory error reporting. Following issues are seen: * Error record shows insufficient data, such as "EDAC MC0: 1 CE unknown error on unknown label", * DMI DIMM labels are not decoded for error reporting, * No memory hierarchy known (NUMA topology), * No per layer reporting, * Significant differences to x86 error reports. This patch set addresses all the above involving a rework of the ghes_edac and edac_mc driver. Patch #1-#4: Fix of grain calculation in edac_mc.c (#1) and ghes_edac.c (#2) including unification of trace_mc_event() code (#3, #4). Patches #5-#12: General fixes and improvements of the ghes and mc drivers. Most of it is a rework of existing code without functional changes to improve, ease, cleanup and join common code. The changes are in preparation of and a requirment for the following patches that improve ghes error reports. Patches #13-#22: Improve error memory reporting of the ghes driver including: * support for legacy API (patch #12), * NUMA detection, one mc device per node (patches #13-#16), * support for DMI DIMM label information (patch #17), * per-layer reporting (patches #18-#20). Patch #23: Documentation updates. Patch #24: Disable legacy API for ARM64 ghes driver (optional, need to be ack'ed by James, I vote for not applying it). All changes should keep existing systems working as before. All systems that are using ghes will also benefit from the update. There is a fallback in the ghes driver that disables NUMA or enters a fake mode if some of the NUMA or DIMM information is inconsistent. So it should not break existing systems that provide broken firmware tables. The series has been tested on a Marvell/Cavium ThunderX2 system. Here some example logs and sysfs entries: Boot log of memory hierarchy and dimm detection: EDAC DEBUG: mem_info_setup: DIMM0: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x0038, label: N0 DIMM_A0 EDAC DEBUG: mem_info_setup: DIMM1: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x0039, label: N0 DIMM_B0 EDAC DEBUG: mem_info_setup: DIMM2: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003a, label: N0 DIMM_C0 EDAC DEBUG: mem_info_setup: DIMM3: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003b, label: N0 DIMM_D0 EDAC DEBUG: mem_info_setup: DIMM4: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003c, label: N0 DIMM_E0 EDAC DEBUG: mem_info_setup: DIMM5: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003d, label: N0 DIMM_F0 EDAC DEBUG: mem_info_setup: DIMM6: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003e, label: N0 DIMM_G0 EDAC DEBUG: mem_info_setup: DIMM7: Found mem range [0x0000008800000000-0x0000009ffcffffff] on node 0, handle: 0x003f, label: N0 DIMM_H0 EDAC DEBUG: mem_info_setup: DIMM8: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x004f, label: N1 DIMM_I0 EDAC DEBUG: mem_info_setup: DIMM9: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0050, label: N1 DIMM_J0 EDAC DEBUG: mem_info_setup: DIMM10: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0051, label: N1 DIMM_K0 EDAC DEBUG: mem_info_setup: DIMM11: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0052, label: N1 DIMM_L0 EDAC DEBUG: mem_info_setup: DIMM12: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0053, label: N1 DIMM_M0 EDAC DEBUG: mem_info_setup: DIMM13: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0054, label: N1 DIMM_N0 EDAC DEBUG: mem_info_setup: DIMM14: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0055, label: N1 DIMM_O0 EDAC DEBUG: mem_info_setup: DIMM15: Found mem range [0x0000009ffd000000-0x000000bffcffffff] on node 1, handle: 0x0056, label: N1 DIMM_P0 DIMM label entries in sysfs: # grep . /sys/devices/system/edac/mc/mc*/dimm*/dimm_label /sys/devices/system/edac/mc/mc0/dimm0/dimm_label:N0 DIMM_A0 /sys/devices/system/edac/mc/mc0/dimm1/dimm_label:N0 DIMM_B0 /sys/devices/system/edac/mc/mc0/dimm2/dimm_label:N0 DIMM_C0 /sys/devices/system/edac/mc/mc0/dimm3/dimm_label:N0 DIMM_D0 /sys/devices/system/edac/mc/mc0/dimm4/dimm_label:N0 DIMM_E0 /sys/devices/system/edac/mc/mc0/dimm5/dimm_label:N0 DIMM_F0 /sys/devices/system/edac/mc/mc0/dimm6/dimm_label:N0 DIMM_G0 /sys/devices/system/edac/mc/mc0/dimm7/dimm_label:N0 DIMM_H0 /sys/devices/system/edac/mc/mc1/dimm0/dimm_label:N1 DIMM_I0 /sys/devices/system/edac/mc/mc1/dimm1/dimm_label:N1 DIMM_J0 /sys/devices/system/edac/mc/mc1/dimm2/dimm_label:N1 DIMM_K0 /sys/devices/system/edac/mc/mc1/dimm3/dimm_label:N1 DIMM_L0 /sys/devices/system/edac/mc/mc1/dimm4/dimm_label:N1 DIMM_M0 /sys/devices/system/edac/mc/mc1/dimm5/dimm_label:N1 DIMM_N0 /sys/devices/system/edac/mc/mc1/dimm6/dimm_label:N1 DIMM_O0 /sys/devices/system/edac/mc/mc1/dimm7/dimm_label:N1 DIMM_P0 Memory error reports in the kernel log: {1}[Hardware Error]: Error 4, type: corrected {1}[Hardware Error]: section_type: memory error {1}[Hardware Error]: error_status: 0x0000000000000400 {1}[Hardware Error]: physical_address: 0x000000bd0db44000 {1}[Hardware Error]: node: 1 card: 3 module: 0 rank: 0 bank: 256 column: 10 bit_position: 16 {1}[Hardware Error]: DIMM location: N1 DIMM_L0 EDAC MC1: 1 CE ghes_mc on N1 DIMM_L0 (card:3 module:0 page:0xbd0db44 offset:0x0 grain:0 syndrome:0x0 -
