On this series, the first 6 patches chang to the math used to calculate offsets at HEST table and hardware_error firmware file, together with its migration code. Migration tested with both latest QEMU released kernel and upstream, on both directions. The next patches add a new QAPI to allow injecting GHESv2 errors, and a script using such QAPI to inject ARM Processor Error records. --- v4: - added an extra comment for AcpiGhesState structure; - patches reordered; - no functional changes, just code shift between the patches in this series. v3: - addressed more nits; - hest_add_le now points to the beginning of HEST table; - removed HEST from tests/data/acpi; - added an extra patch to not use fw_cfg with virt-10.0 for hw_error_le v2: - address some nits; - improved ags cleanup patch and removed ags.present field; - added some missing le*_to_cpu() calls; - update date at copyright for new files to 2024-2025; - qmp command changed to: inject-ghes-v2-error ans since updated to 10.0; - added HEST and DSDT tables after the changes to make check target happy. (two patches: first one whitelisting such tables; second one removing from whitelist and updating/adding such tables to tests/data/acpi) Mauro Carvalho Chehab (14): acpi/ghes: prepare to change the way HEST offsets are calculated acpi/ghes: add a firmware file with HEST address acpi/ghes: Use HEST table offsets when preparing GHES records acpi/ghes: don't hard-code the number of sources for HEST table acpi/ghes: add a notifier to notify when error data is ready acpi/ghes: create an ancillary acpi_ghes_get_state() function acpi/generic_event_device: Update GHES migration to cover hest addr acpi/generic_event_device: add logic to detect if HEST addr is available acpi/generic_event_device: add an APEI error device tests/acpi: virt: allow acpi table changes for a new table: HEST arm/virt: Wire up a GED error device for ACPI / GHES tests/acpi: virt: add a HEST table to aarch64 virt and update DSDT qapi/acpi-hest: add an interface to do generic CPER error injection scripts/ghes_inject: add a script to generate GHES error inject MAINTAINERS | 10 + hw/acpi/Kconfig | 5 + hw/acpi/aml-build.c | 10 + hw/acpi/generic_event_device.c | 43 ++ hw/acpi/ghes-stub.c | 7 +- hw/acpi/ghes.c | 231 ++++-- hw/acpi/ghes_cper.c | 38 + hw/acpi/ghes_cper_stub.c | 19 + hw/acpi/meson.build | 2 + hw/arm/virt-acpi-build.c | 37 +- hw/arm/virt.c | 19 +- hw/core/machine.c | 2 + include/hw/acpi/acpi_dev_interface.h | 1 + include/hw/acpi/aml-build.h | 2 + include/hw/acpi/generic_event_device.h | 1 + include/hw/acpi/ghes.h | 54 +- include/hw/arm/virt.h | 2 + qapi/acpi-hest.json | 35 + qapi/meson.build | 1 + qapi/qapi-schema.json | 1 + scripts/arm_processor_error.py | 476 ++++++++++++ scripts/ghes_inject.py | 51 ++ scripts/qmp_helper.py | 702 ++++++++++++++++++ target/arm/kvm.c | 7 +- tests/data/acpi/aarch64/virt/DSDT | Bin 5196 -> 5240 bytes .../data/acpi/aarch64/virt/DSDT.acpihmatvirt | Bin 5282 -> 5326 bytes tests/data/acpi/aarch64/virt/DSDT.memhp | Bin 6557 -> 6601 bytes tests/data/acpi/aarch64/virt/DSDT.pxb | Bin 7679 -> 7723 bytes tests/data/acpi/aarch64/virt/DSDT.topology | Bin 5398 -> 5442 bytes 29 files changed, 1677 insertions(+), 79 deletions(-) create mode 100644 hw/acpi/ghes_cper.c create mode 100644 hw/acpi/ghes_cper_stub.c create mode 100644 qapi/acpi-hest.json create mode 100644 scripts/arm_processor_error.py create mode 100755 scripts/ghes_inject.py create mode 100755 scripts/qmp_helper.py
