Currently, offsets needed to store ACPI HEST offsets and read ack are calculated based on a previous knowledge from the logic which creates the HEST table. Such logic is not generic, not allowing to easily add more HEST entries nor replicates what OSPM does. As the next patches will be adding a more generic logic, add a new use_hest_addr, set to false, in preparation for such changes.

The start address of the CPER block to be stored; 2. The address of the read ack. It is preferable to calculate them from the HEST table. This allows checking the source ID, the size of the table and the type of the HEST error block structures. Yet, keep the old code, as this is needed for migration purposes from older QEMU versions.

As the number of sources should be arch-dependent, as it will depend on what kind of notifications will exist, and how many errors can be reported at the same time, change the logic to be more flexible, allowing the number of sources to be defined when building the HEST table by the caller.

Error injection uses ACPI_HEST_SRC_ID_QMP source ID to be platform independent. This is mapped at arch virt bindings, depending on the types supported by QEMU and by the BIOS. So, on ARM, this is supported via ACPI_GHES_NOTIFY_GPIO notification type. This patch is co-authored: - original ghes logic to inject a simple ARM record by Shiju Jose; - generic logic to handle block addresses by Jonathan Cameron; - generic GHESv2 error inject by Mauro Carvalho Chehab; Co-authored-by: Jonathan Cameron Co-authored-by: Shiju Jose Co-authored-by: Mauro Carvalho Chehab Signed-off-by: Jonathan Cameron Signed-off-by: Shiju Jose Signed-off-by: Mauro Carvalho Chehab Acked-by: Igor Mammedov Acked-by: Markus Armbruster --- MAINTAINERS | 7 +++++++ hw/acpi/Kconfig | 5 +++++ hw/acpi/ghes.c | 2 +- hw/acpi/ghes_cper.c | 38 ++++++++++++++++++++++++++++++++++++++ hw/acpi/ghes_cper_stub.c | 19 +++++++++++++++++++ hw/acpi/meson.build | 2 ++ hw/arm/virt-acpi-build.c | 1 + hw/arm/virt.c | 7 +++++++ include/hw/acpi/ghes.h | 1 + include/hw/arm/virt.h | 1 + qapi/acpi-hest.json | 35 +++++++++++++++++++++++++++++++++++ qapi/meson.build | 1 + qapi/qapi-schema.json | 1 + 13 files changed, 119 insertions(+), 1 deletion(-) create mode 100644 hw/acpi/ghes_cper.c create mode 100644 hw/acpi/ghes_cper_stub.c create mode 100644 qapi/acpi-hest.json diff --git a/MAINTAINERS b/MAINTAINERS index 692628cd7801..479664a4f6e8 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -2091,6 +2091,13 @@ F: hw/acpi/ghes.c F: include/hw/acpi/ghes.h F: docs/specs/acpi_hest_ghes.rst =20 +ACPI/HEST/GHES/ARM processor CPER +R: Mauro Carvalho Chehab +S: Maintained +F: hw/arm/ghes_cper.c +F: hw/acpi/ghes_cper_stub.c +F: qapi/acpi-hest.json + ppc4xx L: qemu-ppc@nongnu.org S: Orphan diff --git a/hw/acpi/Kconfig b/hw/acpi/Kconfig index 1d4e9f0845c0..daabbe6cd11e 100644 --- a/hw/acpi/Kconfig +++ b/hw/acpi/Kconfig @@ -51,6 +51,11 @@ config ACPI_APEI bool depends on ACPI =20 +config GHES_CPER + bool + depends on ACPI_APEI + default y + config ACPI_PCI bool depends on ACPI && PCI diff --git a/hw/acpi/ghes.c b/hw/acpi/ghes.c index 0135ac844bcf..1d02ef6dcb70 100644 --- a/hw/acpi/ghes.c +++ b/hw/acpi/ghes.c @@ -553,7 +553,7 @@ void ghes_record_cper_errors(AcpiGhesState *ags, const = void *cper, size_t len, /* Write the generic error data entry into guest memory */ cpu_physical_memory_write(cper_addr, cper, len); =20 - notifier_list_notify(&acpi_generic_error_notifiers, NULL); + notifier_list_notify(&acpi_generic_error_notifiers, &source_id); } =20 int acpi_ghes_memory_errors(AcpiGhesState *ags, uint16_t source_id, diff --git a/hw/acpi/ghes_cper.c b/hw/acpi/ghes_cper.c new file mode 100644 index 000000000000..0a2d95dd8b27 --- /dev/null +++ b/hw/acpi/ghes_cper.c @@ -0,0 +1,38 @@ +/* + * CPER payload parser for error injection + * + * Copyright(C) 2024-2025 Huawei LTD. + * + * This code is licensed under the GPL version 2 or later.
