It ok for code to be more complicated so it would be able to handle other usecases in the future. But if there aren't actual plans to add other usecases, then it's just over-engineering which might mislead reader later on to trying figure out what's going on here. (modulo the case where we are defining ABI between guest and QEMU) So I'd rather simplify code if there aren't plans to extend it, and let someone else to generalize it when there is an actual need for it. > > > + } > > + > > + /* Generic Error Status Block offset in the hardware error fw_cfg blob */ > > + error_status_block_offset = hardware_errors->len; > > + > > + /* Build Error Status Data Block */ > > + build_append_int_noprefix(hardware_errors, 0, > > + ACPI_GHES_MAX_RAW_DATA_LENGTH * ACPI_GHES_ERROR_SOURCE_COUNT); > > + > > + /* Allocate guest memory for the hardware error fw_cfg blob */ > > + bios_linker_loader_alloc(linker, ACPI_GHES_ERRORS_FW_CFG_FILE, > > + hardware_errors, 1, false); > > + > > + for (i = 0; i < ACPI_GHES_ERROR_SOURCE_COUNT; i++) { > > + /* > > + * Patch the address of Error Status Data Block into > > + * the error_block_address of hardware_errors fw_cfg blob > > + */ > > + bios_linker_loader_add_pointer(linker, > > + ACPI_GHES_ERRORS_FW_CFG_FILE, ACPI_GHES_ADDRESS_SIZE * i, > > + ACPI_GHES_ADDRESS_SIZE, ACPI_GHES_ERRORS_FW_CFG_FILE, > > + error_status_block_offset + i * ACPI_GHES_MAX_RAW_DATA_LENGTH); > > + } > > + > > + /* > > + * Write the address of hardware_errors fw_cfg blob into the > > + * hardware_errors_addr fw_cfg blob. > > + */ > > + bios_linker_loader_write_pointer(linker, ACPI_GHES_DATA_ADDR_FW_CFG_FILE, > > + 0, ACPI_GHES_ADDRESS_SIZE, ACPI_GHES_ERRORS_FW_CFG_FILE, 0); > > +} > > + > > +/* Build Hardware Error Source Table */ > > +void acpi_ghes_build_hest(GArray *table_data, GArray *hardware_errors, > > + BIOSLinker *linker) > > +{ > > + uint32_t hest_start = table_data->len; > > + uint32_t source_id = 0; > > + > > + /* Hardware Error Source Table header*/ > > + acpi_data_push(table_data, sizeof(AcpiTableHeader)); > > + > > + /* Error Source Count */ > > + build_append_int_noprefix(table_data, ACPI_GHES_ERROR_SOURCE_COUNT, 4); > > + > > + /* > > + * Type: > > + * Generic Hardware Error Source version 2(GHESv2 - Type 10) > > + */ > > + build_append_int_noprefix(table_data, ACPI_GHES_SOURCE_GENERIC_ERROR_V2, 2); > > + /* > > + * Source Id > > + * Once we support more than one hardware error sources, we need to > > + * increase the value of this field. > > + */ > > + build_append_int_noprefix(table_data, source_id, 2); > > + /* Related Source Id */ > > + build_append_int_noprefix(table_data, 0xffff, 2); > > Would be nice to have a comment on the value used -> > 'no alternate sources' usually we use verbaltim field name as in the spec table definition. This way reader could easily find it in the spec and read on the meaning of values. This is done to avoid copying needlessly spec text into QEMU. So if 0xffff is described in the table definition, then typically just field name comment is sufficient. > > + /* Flags */ > > + build_append_int_noprefix(table_data, 0, 1); > > + /* Enabled */ > > + build_append_int_noprefix(table_data, 1, 1); > > + > > + /* Number of Records To Pre-allocate */ > > + build_append_int_noprefix(table_data, 1, 4); > > + /* Max Sections Per Record */ > > + build_append_int_noprefix(table_data, 1, 4); > > + /* Max Raw Data Length */ > > + build_append_int_noprefix(table_data, ACPI_GHES_MAX_RAW_DATA_LENGTH, 4); > > + > > + /* Error Status Address */ > > + build_append_gas(table_data, AML_AS_SYSTEM_MEMORY, 0x40, 0, > > + 4 /* QWord access */, 0); > > + bios_linker_loader_add_pointer(linker, ACPI_BUILD_TABLE_FILE, > > + ACPI_GHES_ERROR_STATUS_ADDRESS_OFFSET(hest_start, source_id), > > + ACPI_GHES_ADDRESS_SIZE, ACPI_GHES_ERRORS_FW_CFG_FILE, > > + source_id * ACPI_GHES_ADDRESS_SIZE); > > + > > + /* > > + * Notification Structure > > + * Now only enable ARMv8 SEA notification type > > + */ > > + acpi_ghes_build_notify(table_data, ACPI_GHES_NOTIFY_SEA); > > + > > + /* Error Status Block Length */ > > + build_append_int_noprefix(table_data, ACPI_GHES_MAX_RAW_DATA_LENGTH, 4); > > + > > + /* > > + * Read Ack Register > > + * ACPI 6.1: 18.3.2.8 Generic Hardware Error Source > > + * version 2 (GHESv2 - Type 10) > > + */ > > + build_append_gas(table_data, AML_AS_SYSTEM_MEMORY, 0x40, 0, > > + 4 /* QWord access */, 0); > > + bios_linker_loader_add_pointer(linker, ACPI_BUILD_TABLE_FILE, > > + ACPI_GHES_READ_ACK_REGISTER_ADDRESS_OFFSET(hest_start, 0), > > + ACPI_GHES_ADDRESS_SIZE, ACPI_GHES_ERRORS_FW_CFG_FILE, > > + (ACPI_GHES_ERROR_SOURCE_COUNT + source_id) * ACPI_GHES_ADDRESS_SIZE); > > + > > + /* > > + * Read Ack Preserve > > + * We only provide the first bit in Read Ack Register to OSPM to write > > + * while the other bits are preserved. > > + */ > > + build_append_int_noprefix(table_data, ~0x1ULL, 8); > > + /* Read Ack Write */ > > + build_append_int_noprefix(table_data, 0x1, 8); > > + > > + build_header(linker, table_data, (void *)(table_data->data + hest_start), > > + "HEST", table_data->len - hest_start, 1, NULL, "GHES"); > > +} > > + > Already mentioned .... but ... > the last few lines are GHESv2 specific but it seems that HES/GHES/GHESv2 > are being mixed within this patch.
