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. The proper solution is to make ghes_edac a proper module. Changelog: v6: - no code changes from v5 patches - add the reviewed and acked by from Toshi - describe the removal of ghes_edac_force_enable checking in Patch 05 v5: https://www.spinics.net/lists/kernel/msg4502787.html - add the review-by from Toshi for patch 04 and 06 - refine the commit msg - remove the unconditional set of ghes_edac_force_enable on Arm v4: https://lore.kernel.org/lkml/20220831074027.13849-6-justin.he@arm.com/ - move the kernel boot option to ghes module parameter - collapse th ghes_present and ghes_edac_preferred into one patch v3: https://lore.kernel.org/lkml/20220822154048.188253-1-justin.he@arm.com/ - 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 v2: https://lore.kernel.org/lkml/20220817143458.335938-1-justin.he@arm.com/ - 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 v1: https://lore.kernel.org/lkml/20220811091713.10427-1-justin.he@arm.com/ Jia He (8): efi/cper: export several helpers for ghes_edac to use EDAC/ghes: Add a notifier for reporting memory errors EDAC:ghes: Move ghes_edac.force_load to ghes module parameter ghes: Introduce a helper ghes_edac_preferred() EDAC/ghes: Make ghes_edac a proper module to remove the dependency on ghes EDAC: Add the ghes_edac_preferred check for chipset-specific edac drivers apei/ghes: Use unrcu_pointer for cmpxchg EDAC/igen6: Return consistent errno when another edac driver is enabled drivers/acpi/apei/ghes.c | 82 +++++++++++++++++++++++++++++++--- 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 | 78 ++++++++++++++++++++------------ 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/apei.h | 2 + include/acpi/ghes.h | 36 +++++---------- 17 files changed, 175 insertions(+), 63 deletions(-)
