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.
