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/lynxpoint/acpi/globalnvs.asl | 1 - src/southbridge/intel/lynxpoint/acpi/xhci.asl | 1 - 2 files changed, 2 deletions(-) (limited to 'src/southbridge/intel/lynxpoint') diff --git a/src/southbridge/intel/lynxpoint/acpi/globalnvs.asl b/src/southbridge/intel/lynxpoint/acpi/globalnvs.asl index ccf9b087b3..482718a4ea 100644 --- a/src/southbridge/intel/lynxpoint/acpi/globalnvs.asl +++ b/src/southbridge/intel/lynxpoint/acpi/globalnvs.asl @@ -16,7 +16,6 @@ OperationRegion (GNVS, SystemMemory, NVSA, 0xf00) 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/lynxpoint/acpi/xhci.asl b/src/southbridge/intel/lynxpoint/acpi/xhci.asl index fbeb56200a..a65b1f6202 100644 --- a/src/southbridge/intel/lynxpoint/acpi/xhci.asl +++ b/src/southbridge/intel/lynxpoint/acpi/xhci.asl @@ -12,7 +12,6 @@ Device (XHCI) OperationRegion (XPRT, PCI_Config, 0, 0x100) Field (XPRT, AnyAcc, NoLock, Preserve) { - Offset (0x0), DVID, 16, Offset (0x10), , 16, -- cgit v1.2.3
