Because at that time, the bus "edac" hasn't been even registered, this created sysfs /devices/mc0 instead of /sys/devices/system/edac/mc/mc0 on an Ampere eMag server. Changelog: v3: - refine the commit logs - introduce ghes preferred and present flag (by Toshi) - move force_load to setup parameter - add the ghes_edac_preferred() check for x86/Arm edac drivers (incompleted list) v2: - add acked-by tag of Patch 1 from Ard - split the notifier patch - add 2 patch to get regular drivers selected when ghes edac is not loaded - fix an errno in igen6 driver - add a patch to fix the sparse warning of ghes - refine the commit logs Jia He (9): efi/cper: export several helpers for ghes_edac to use EDAC/ghes: Add a notifier for reporting memory errors EDAC/ghes: Make ghes_edac a proper module to remove the dependency on ghes EDAC/ghes: Move ghes_edac.force_load to setup parameter EDAC: Don't load chipset-specific edac drivers when ghes_edac is preferred ghes: Introduce a flag ghes_present apei/ghes: Use unrcu_pointer for cmpxchg EDAC/igen6: Keep returned errno consistent when edac mc has been enabled edac: Don't load Arm specific edac drivers when ghes_edac is preferred .../admin-guide/kernel-parameters.txt | 5 + drivers/acpi/apei/ghes.c | 94 ++++++++++++++-- drivers/edac/Kconfig | 4 +- drivers/edac/amd64_edac.c | 3 + drivers/edac/armada_xp_edac.c | 3 + drivers/edac/edac_module.h | 1 + drivers/edac/ghes_edac.c | 102 +++++++++++------- drivers/edac/i10nm_base.c | 3 + drivers/edac/igen6_edac.c | 5 +- drivers/edac/layerscape_edac.c | 3 + drivers/edac/pnd2_edac.c | 3 + drivers/edac/sb_edac.c | 3 + drivers/edac/skx_base.c | 3 + drivers/edac/thunderx_edac.c | 3 + drivers/edac/xgene_edac.c | 3 + drivers/firmware/efi/cper.c | 3 + include/acpi/ghes.h | 38 +++---- 17 files changed, 204 insertions(+), 75 deletions(-) Signed-off-by: Some, one
