Issue is not fatal but as result acpi-index/"PCI Label ID" property is either not shown in device details page or shows incorrect value. Fix it by doing assignment of BSEL/ASUN values to package elements manually after package declaration. Fix was tested with: WS2012r2, WS2022, RHEL9 Fixes: 467d099a2985 (x86: acpi: _DSM: use Package to pass parameters) Signed-off-by: Igor Mammedov --- hw/i386/acpi-build.c | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/hw/i386/acpi-build.c b/hw/i386/acpi-build.c index 9c74fa17ad..19d268ff59 100644 --- a/hw/i386/acpi-build.c +++ b/hw/i386/acpi-build.c @@ -362,9 +362,13 @@ Aml *aml_pci_device_dsm(void) { Aml *params = aml_local(0); Aml *pkg = aml_package(2); - aml_append(pkg, aml_name("BSEL")); - aml_append(pkg, aml_name("ASUN")); + aml_append(pkg, aml_int(0)); + aml_append(pkg, aml_int(0)); aml_append(method, aml_store(pkg, params)); + aml_append(method, + aml_store(aml_name("BSEL"), aml_index(params, aml_int(0)))); + aml_append(method, + aml_store(aml_name("ASUN"), aml_index(params, aml_int(1)))); aml_append(method, aml_return(aml_call5("PDSM", aml_arg(0), aml_arg(1), aml_arg(2), aml_arg(3), params))
