[Qemu-arm] [PATCH v5 1/3] ACPI: Add new ACPI structures and macros |
|
Date: |
Wed, 12 Jul 2017 10:08:15 +0800 |
(1) Add related APEI/HEST table structures and macros, these
definition refer to ACPI 6.1 and UEFI 2.6 spec.
(2) Add generic error status block and CPER memory section
definition, user space only handle memory section errors.

thanks Laszlo and Michael's review:
chnage since v4:
(1) fix email threading in this series is incorrect issue
change since v3:
(1) separate the original one patch into three patches: one is new
ACPI structures and macros, another is C source file to generate ACPI HEST
table and dynamically record CPER ,final patch is the change about Makefile
and configuration
(2) add comments about where the ACPI structures and macros come from, for
example,
they come from the UEFI Spec 2.6, "xxxxxxxxxxxx"; ACPI 6.1 spec,
"xxxxxxxxxxxxxx".
(3) correct the macros name, for emaple, prefix some macro names with
"UEFI_".
(4) remove the uuid_le struct and use the QemuUUID in the include/qemu/uuid.h"
(5) remove the duplicate ACPI address space, because it already defined in
the "include/hw/acpi/aml-build.h"
(6) remove the acpi_generic_address structure because same definition exists in
the
AcpiGenericAddress.
(7) rename the struct acpi_hest_notify to AcpiHestNotifyType
(8) rename the struct acpi_hest_types to AcpiHestSourceType
(9) rename enum constants AcpiHestSourceType to ACPI_HEST_SOURCE_xxx from
ACPI_HEST_TYPE_xxx
(10) remove the NOT_USED{3,4,5} enum constants in the AcpiHestSourceType.
(11) add missed QEMU_PACKED for the struct definition.
(12) remove the defnition of AcpiGenericErrorData, and rename the
AcpiGenericErrorDataV300 to AcpiGenericErrorData.
(13) use the QemuUUID type for the "section_type" field AcpiGenericErrorData,
and rename it
to section_type_le.
(14) moving type AcpiGenericErrorSeverity above AcpiGenericErrorData and
AcpiGenericErrorDataV300, and remarking on the "error_severity" fields
that they take their values from AcpiGenericErrorSeverity
(15) remove the wrongly call to BERT(Boot Error Record Table)
(16) add comments for the struction member, for example, pint out that
the block_status member in the AcpiGenericErrorStatus is a bitmask
composed of ACPI_GEBS_xxx macros
(17) remove the hardware error source notification type list, and rename
the MAX_ERROR_SOURCE_COUNT_V6 to ACPI_HEST_NOTIFY_RESERVED.
(18) remove the physical_addr member of GhesErrorState
(19) change the "uint64_t ghes_addr_le[8]" in GhesErrorState to uint64_t
ghes_addr_le
(20) change the second parameter to "error_physical_addr" in the
ghes_update_guest
API statement
