Given that the series accumulated a bunch of cleanups, I'd suggest to move all cleanups/renamings not related to new HEST lookup and new src id mapping to the beginning of the series, so once they reviewed they could be split up into a separate series that could be merged while we are ironing down the new functionality. > --- > > v10: > - Patch 1 split on several patches to make reviews easier; > - Added a migration patch; > - CPER QMP command was renamed; > - Updated some comments to better reflect exact ACPI version; > - Removed a code to reset acks when OSPM fails to read records; > - Removed a duplicated config GHES_CPER symbol; > - There is now an arch-independent namespace for GHES source IDs; > - Fixed the size of hest_ghes_notify array when creating tables; > - acpi-hest.json is now a section of ACPI; > - QMP command renamed from @ghes-cper to inject-ghes-error. > > v9: > - Patches reorganized to make easier for reviewers; > - source ID is now guest-OS specific; > - Some patches got a revision history since v8; > - Several minor cleanups. > > v8: > - Fix one of the BIOS links that were incorrect; > - Changed mem error internal injection to use a common code; > - No more hardcoded values for CPER: instead of using just the > payload at the QAPI, it now has the full raw CPER there; > - Error injection script now supports changing fields at the > Generic Error Data section of the CPER; > - Several minor cleanups. > > v7: > - Change the way offsets are calculated and used on HEST table. > Now, it is compatible with migrations as all offsets are relative > to the HEST table; > - GHES interface is now more generic: the entire CPER is sent via > QMP, instead of just the payload; > - Some code cleanups to make the code more robust; > - The python script now uses QEMUMonitorProtocol class. > > v6: > - PNP0C33 device creation moved to aml-build.c; > - acpi_ghes record functions now use ACPI notify parameter, > instead of source ID; > - the number of source IDs is now automatically calculated; > - some code cleanups and function/var renames; > - some fixes and cleanups at the error injection script; > - ghes cper stub now produces an error if cper JSON is not compiled; > - Offset calculation logic for GHES was refactored; > - Updated documentation to reflect the GHES allocated size; > - Added a x-mpidr object for QOM usage; > - Added a patch making usage of x-mpidr field at ARM injection > script; > > v5: > - CPER guid is now passing as string; > - raw-data is now passed with base64 encode; > - Removed several GPIO left-overs from arm/virt.c changes; > - Lots of cleanups and improvements at the error injection script. > It now better handles QMP dialog and doesn't print debug messages. > Also, code was split on two modules, to make easier to add more > error injection commands. > > v4: > - CPER generation moved to happen outside QEMU; > - One patch adding support for mpidr query was removed. > > v3: > - patch 1 cleanups with some comment changes and adding another place where > the poweroff GPIO define should be used.

I've rebased the series placing the preparation stuff (cleanups and renames) at the beginning. So, what I have now is: 1) preparation patches: 41709f0898e1 acpi/ghes: get rid of ACPI_HEST_SRC_ID_RESERVED 5409daa41c78 acpi/ghes: simplify acpi_ghes_record_errors() code 2539f1f662b9 acpi/ghes: better handle source_id and notification 3f19400549c1 acpi/ghes: Remove a duplicated out of bounds check f0b06ecede46 acpi/ghes: Change the type for source_id 9f08301ac195 acpi/ghes: Prepare to support multiple sources on ghes 2426cd76e868 acpi/ghes: make the GHES record generation more generic 3fb7ec864700 acpi/ghes: better name GHES memory error function 1a22dad3211e acpi/ghes: don't crash QEMU if ghes GED is not found 726968d4ee20 acpi/ghes: rename etc/hardware_error file macros f562380da7ce docs: acpi_hest_ghes: fix documentation for CPER size 69850f550f99 acpi/generic_event_device: add an APEI error device Patches were changed to ensure that they won't be add any new new features. They are just code shift in order to make the diff of the next patches smaller. There is a small point here: the logic was simplified to only support a single source ID (I added an assert() to enforce it) and simplified the calculus in preparation for the HEST and migration series. 2) add a BIOS pointer to HEST, using it. The migration stuff will be along those: c24f1a8708e3 acpi/ghes: add a firmware file with HEST address 853dce23ec39 acpi/ghes: Use HEST table offsets when preparing GHES records c148716fd7c8 acpi/generic_event_device: Update GHES migration to cover hest addr Up to that, still no new features, but the offset calculus will be relative to HEST table and will use the bios pointers stored there; 3) Add support for generic error inject: f5ec0d197d82 acpi/ghes: add a notifier to notify when error data is ready f5e015537209 arm/virt: Wire up a GED error device for ACPI / GHES 3b6692dbf473 qapi/acpi-hest: add an interface to do generic CPER error injection 620a5a49f218 scripts/ghes_inject: add a script to generate GHES error inject 4) MPIDR property: 2dd6e3aae450 target/arm: add an experimental mpidr arm cpu property object 02c88cd4daa2 scripts/arm_processor_error.py: retrieve mpidr if not filled I'm still testing if the rebase didn't cause any issues. So, the above may still change a little bit. I also need to address your comments to the cleanup patches and work at the migration, but just want to double check if this is what you want. If OK to you, my plan is to submit you the cleanup patches after I finish testing the hole series. The migration logic will require some time, and I don't want to bother with the cleanup stuff while doing it. So, perhaps while I'm doing it, you could review/merge the cleanups. We can do the same for each of the 4 above series of patches, as it makes review simpler as there will be less patches to look into on each series. Would it work for you? Thanks, Mauro

For the migration, there are how two functions at ghes.c: The one compatible with current behavior (up to version 9.1): https://gitlab.com/mchehab_kernel/qemu/-/blob/qemu_submission_v11b/hw/acpi/ghes.c?ref_type=heads#L411 And the new one using offsets calculated from HEST (newer versions): https://gitlab.com/mchehab_kernel/qemu/-/blob/qemu_submission_v11b/hw/acpi/ghes.c?ref_type=heads#L437 With that, the migration logic can decide what function should be called (currently, it is just checking if hest_addr_le is zero, but I guess I'll need to change it to match some variable added by the migration path. Also, in preparation for the migration tests, I created a separate branch at: https://gitlab.com/mchehab_kernel/qemu/-/commits/ghes_on_v9.1.0?ref_type=heads which contains the same patches on the top of 9.1, except for the HEST ones. It also contains a hack to use ACPI_GHES_NOTIFY_GPIO instead of ACPI_GHES_NOTIFY_SEA. With that, we have a way to use the same error injection logic on both 9.1 and upstream, hopefully being enough to test if migration works. Thanks, Mauro
This series add support for injecting generic CPER records. Such records are generated outside QEMU via a provided script. On this version, the patch reworking the way offsets are calculated were split on several other patches, to make one logical change per patch and make review easier. Despite the number of patches increased from 12 to 21, there is just one real new patch (as the other ones are a split from a big change): acpi/generic_event_device: Update GHES migration to cover hest addr --- v10: - Patch 1 split on several patches to make reviews easier; - Added a migration patch; - CPER QMP command was renamed; - Updated some comments to better reflect exact ACPI version; - Removed a code to reset acks when OSPM fails to read records; - Removed a duplicated config GHES_CPER symbol; - There is now an arch-independent namespace for GHES source IDs; - Fixed the size of hest_ghes_notify array when creating tables; - acpi-hest.json is now a section of ACPI; - QMP command renamed from @ghes-cper to inject-ghes-error. v9: - Patches reorganized to make easier for reviewers; - source ID is now guest-OS specific; - Some patches got a revision history since v8; - Several minor cleanups. v8: - Fix one of the BIOS links that were incorrect; - Changed mem error internal injection to use a common code; - No more hardcoded values for CPER: instead of using just the payload at the QAPI, it now has the full raw CPER there; - Error injection script now supports changing fields at the Generic Error Data section of the CPER; - Several minor cleanups. v7: - Change the way offsets are calculated and used on HEST table. Now, it is compatible with migrations as all offsets are relative to the HEST table; - GHES interface is now more generic: the entire CPER is sent via QMP, instead of just the payload; - Some code cleanups to make the code more robust; - The python script now uses QEMUMonitorProtocol class. v6: - PNP0C33 device creation moved to aml-build.c; - acpi_ghes record functions now use ACPI notify parameter, instead of source ID; - the number of source IDs is now automatically calculated; - some code cleanups and function/var renames; - some fixes and cleanups at the error injection script; - ghes cper stub now produces an error if cper JSON is not compiled; - Offset calculation logic for GHES was refactored; - Updated documentation to reflect the GHES allocated size; - Added a x-mpidr object for QOM usage; - Added a patch making usage of x-mpidr field at ARM injection script; v5: - CPER guid is now passing as string; - raw-data is now passed with base64 encode; - Removed several GPIO left-overs from arm/virt.c changes; - Lots of cleanups and improvements at the error injection script. It now better handles QMP dialog and doesn't print debug messages. Also, code was split on two modules, to make easier to add more error injection commands. v4: - CPER generation moved to happen outside QEMU; - One patch adding support for mpidr query was removed. v3: - patch 1 cleanups with some comment changes and adding another place where the poweroff GPIO define should be used. No changes on other patches (except due to conflict resolution). v2: - added a new patch using a define for GPIO power pin; - patch 2 changed to also use a define for generic error GPIO pin; - a couple cleanups at patch 2 removing uneeded else clauses.
