From 601ea3d40e39bb528f6418757ae3e8482920198f Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Mon, 23 Nov 2015 12:37:22 -0700 Subject: lenovo t400: Fix IASL warning and remark If any path in a method returns a value, IASL expects that all paths within that method will return a value. Presumably, the ATPX would not need a return value if Arg0 is anything other than 0, so just return a zero. - Serialize ATPX method to make IASL happy. This means that it can only be used by one thread at a time. Fixes these issues: dsdt.aml 2581: Method (ATPX, 2, NotSerialized) { Remark 2120 - ^ Control Method should be made Serialized (due to creation of named objects within) dsdt.aml 2581: Method (ATPX, 2, NotSerialized) { Warning 3115 - ^ Not all control paths return a value (ATPX) Change-Id: I14aeab0cebe4596e06a17cffc36cc01b953d7191 Signed-off-by: Martin Roth Reviewed-on: https://review.coreboot.org/12518 Reviewed-by: Timothy Pearson Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer --- src/mainboard/lenovo/t400/acpi/graphics.asl | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/mainboard/lenovo/t400/acpi/graphics.asl') diff --git a/src/mainboard/lenovo/t400/acpi/graphics.asl b/src/mainboard/lenovo/t400/acpi/graphics.asl index d2cfdb93c2..818ea93724 100644 --- a/src/mainboard/lenovo/t400/acpi/graphics.asl +++ b/src/mainboard/lenovo/t400/acpi/graphics.asl @@ -55,7 +55,7 @@ Method(SHYB, 1) { } } -Method (ATPX, 2, NotSerialized) { +Method (ATPX, 2, Serialized) { /* Create local variables */ Name (ATPR, Buffer (0x08) { 0x0, 0x0, 0x0, 0x0, @@ -94,4 +94,5 @@ Method (ATPX, 2, NotSerialized) { SHYB(0x00) } } + Return(Zero) } -- cgit v1.2.3
