Subject: [PATCH v10 0/7] Make ghes_edac a proper module
Date: Tue, 18 Oct 2022 08:22:07 +0000 [thread overview]
Message-ID: <20221018082214.569504-1-justin.he@arm.com> (raw)
Commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in
apci_init()") introduced a bug that ghes_edac_register() would be invoked
before edac_init(). 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 solution is to make ghes_edac a proper module.
Changelog:
v10:
- add the RCU_INITIALIZER and use the unrcu_pointer wrap for victim
v9:https://lore.kernel.org/lkml/20221017130140.420986-1-justin.he@arm.com/
- drop the unrcu_pointer patch 06 of v8
- add Ard's xchg_release patch to use a better memory barrier
v8:https://lore.kernel.org/lkml/20221010023559.69655-1-justin.he@arm.com/
- merge v7 two force_enable and ghes_get_devices() patches into one
- make force_enable static
v7:https://lore.kernel.org/lkml/20220929023726.73727-1-justin.he@arm.com/
- remove the ghes_edac_preferred and ghes_present (suggested by Borislav)
- adjust the patch splitting, no major functional changes
- remove the r-b tag in those changed patches
v6:https://www.spinics.net/lists/kernel/msg4511453.html
- 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/
