In the later patches, we will dynamical allocate free space within this region which is used by NVDIMM _DSM method Signed-off-by: Xiao Guangrong --- hw/i386/acpi-build.c | 4 ++-- hw/i386/acpi-dsdt.dsl | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/hw/i386/acpi-build.c b/hw/i386/acpi-build.c index 46eddb8..8ead1c1 100644 --- a/hw/i386/acpi-build.c +++ b/hw/i386/acpi-build.c @@ -1348,7 +1348,7 @@ build_ssdt(GArray *table_data, GArray *linker, g_array_append_vals(table_data, ssdt->buf->data, ssdt->buf->len); build_header(linker, table_data, (void *)(table_data->data + table_data->len - ssdt->buf->len), - "SSDT", ssdt->buf->len, 1); + "SSDT", ssdt->buf->len, 2); free_aml_allocator(); } @@ -1586,7 +1586,7 @@ build_dsdt(GArray *table_data, GArray *linker, AcpiMiscInfo *misc) memset(dsdt, 0, sizeof *dsdt); build_header(linker, table_data, dsdt, "DSDT", - misc->dsdt_size, 1); + misc->dsdt_size, 2); } static GArray * diff --git a/hw/i386/acpi-dsdt.dsl b/hw/i386/acpi-dsdt.dsl index a2d84ec..5cd3f0e 100644 --- a/hw/i386/acpi-dsdt.dsl +++ b/hw/i386/acpi-dsdt.dsl @@ -22,7 +22,7 @@ ACPI_EXTRACT_ALL_CODE AcpiDsdtAmlCode DefinitionBlock ( "acpi-dsdt.aml", // Output Filename "DSDT", // Signature - 0x01, // DSDT Compliance Revision + 0x02, // DSDT Compliance Revision "BXPC", // OEMID "BXDSDT", // TABLE ID 0x1 // OEM Revision
