From 48a6c018bcb8a182c4934d2788567e512d490f96 Mon Sep 17 00:00:00 2001 From: Elyes HAOUAS Date: Wed, 8 Jul 2020 09:22:13 +0200 Subject: src: Remove redundant use of ACPI offset(0) IASL version 20180927 and greater, detects Unnecessary/redundant uses of the Offset() operator within a Field Unit list. It then sends a remark "^ Unnecessary/redundant use of Offset" example: OperationRegion (OPR1, SystemMemory, 0x100, 0x100) Field (OPR1) { Offset (0), // Never needed FLD1, 32, Offset (4), // Redundant, offset is already 4 (bytes) FLD2, 8, Offset (64), // OK use of Offset. FLD3, 16, } We will have those remarks: dsdt.asl 14: Offset (0), Remark 2158 - ^ Unnecessary/redundant use of Offset operator dsdt.asl 16: Offset (4), Remark 2158 - ^ Unnecessary/redundant use of Offset operator Change-Id: I260a79ef77025b4befbccc21f5999f89d90c1154 Signed-off-by: Elyes HAOUAS Reviewed-on: https://review.coreboot.org/c/coreboot/+/43283 Reviewed-by: Felix Held Reviewed-by: Marshall Dawson Reviewed-by: Jason Glenesk Tested-by: build bot (Jenkins) --- src/southbridge/intel/i82801jx/acpi/globalnvs.asl | 1 - src/southbridge/intel/i82801jx/acpi/ich10.asl | 2 +- 2 files changed, 1 insertion(+), 2 deletions(-) (limited to 'src/southbridge/intel/i82801jx/acpi') diff --git a/src/southbridge/intel/i82801jx/acpi/globalnvs.asl b/src/southbridge/intel/i82801jx/acpi/globalnvs.asl index 0a0f25511b..5c9e26ea27 100644 --- a/src/southbridge/intel/i82801jx/acpi/globalnvs.asl +++ b/src/southbridge/intel/i82801jx/acpi/globalnvs.asl @@ -15,7 +15,6 @@ OperationRegion (GNVS, SystemMemory, NVSA, 0x100) Field (GNVS, ByteAcc, NoLock, Preserve) { /* Miscellaneous */ - Offset (0x00), OSYS, 16, // 0x00 - Operating System SMIF, 8, // 0x02 - SMI function PRM0, 8, // 0x03 - SMI function parameter diff --git a/src/southbridge/intel/i82801jx/acpi/ich10.asl b/src/southbridge/intel/i82801jx/acpi/ich10.asl index e62f8a1a80..d6136af14f 100644 --- a/src/southbridge/intel/i82801jx/acpi/ich10.asl +++ b/src/southbridge/intel/i82801jx/acpi/ich10.asl @@ -33,7 +33,7 @@ Scope(\) OperationRegion(GPIO, SystemIO, DEFAULT_GPIOBASE, 0x3c) Field(GPIO, ByteAcc, NoLock, Preserve) { - Offset(0x00), // GPIO Use Select + // GPIO Use Select GU00, 8, GU01, 8, GU02, 8, -- cgit v1.2.3
