From be3979c873d23cb0543e635bba59bd85ab67fed0 Mon Sep 17 00:00:00 2001 From: Christian Walter Date: Wed, 18 Dec 2019 15:07:59 +0100 Subject: acpi: Change Processor ACPI Name (Intel only) The ACPI Spec 2.0 states, that Processor declarations should be made within the ACPI namespace \_SB and not \_PR anymore. \_PR is deprecated and is removed here for Intel CPUs only. Tested on: * X11SSH (Kabylake) * CFL Platform * Asus P8Z77-V LX2 and Windows 10 FWTS does not return FAIL anymore on ACPI tests Tested-by: Angel Pons Change-Id: Ib101ed718f90f9056d2ecbc31b13b749ed1fc438 Signed-off-by: Christian Walter Reviewed-on: https://review.coreboot.org/c/coreboot/+/37814 Tested-by: build bot (Jenkins) Reviewed-by: Nico Huber --- src/soc/intel/common/acpi/dptf/cpu.asl | 38 +++++++++++++++++----------------- 1 file changed, 19 insertions(+), 19 deletions(-) (limited to 'src/soc/intel/common/acpi') diff --git a/src/soc/intel/common/acpi/dptf/cpu.asl b/src/soc/intel/common/acpi/dptf/cpu.asl index 99dc32a299..982776f701 100644 --- a/src/soc/intel/common/acpi/dptf/cpu.asl +++ b/src/soc/intel/common/acpi/dptf/cpu.asl @@ -12,11 +12,11 @@ * GNU General Public License for more details. */ -External (\_PR.CP00._PSS, PkgObj) -External (\_PR.CP00._TSS, PkgObj) -External (\_PR.CP00._TPC, MethodObj) -External (\_PR.CP00._PTC, PkgObj) -External (\_PR.CP00._TSD, PkgObj) +External (\_SB.CP00._PSS, PkgObj) +External (\_SB.CP00._TSS, PkgObj) +External (\_SB.CP00._TPC, MethodObj) +External (\_SB.CP00._PTC, PkgObj) +External (\_SB.CP00._TSD, PkgObj) External (\_SB.MPDL, IntObj) Device (DPTF_CPU_DEVICE) @@ -38,8 +38,8 @@ Device (DPTF_CPU_DEVICE) Method (_TSS) { - If (CondRefOf (\_PR.CP00._TSS)) { - Return (\_PR.CP00._TSS) + If (CondRefOf (\_SB.CP00._TSS)) { + Return (\_SB.CP00._TSS) } Else { Return (Package () { @@ -50,8 +50,8 @@ Device (DPTF_CPU_DEVICE) Method (_TPC) { - If (CondRefOf (\_PR.CP00._TPC)) { - Return (\_PR.CP00._TPC) + If (CondRefOf (\_SB.CP00._TPC)) { + Return (\_SB.CP00._TPC) } Else { Return (0) } @@ -59,8 +59,8 @@ Device (DPTF_CPU_DEVICE) Method (_PTC) { - If (CondRefOf (\_PR.CP00._PTC)) { - Return (\_PR.CP00._PTC) + If (CondRefOf (\_SB.CP00._PTC)) { + Return (\_SB.CP00._PTC) } Else { Return (Package () { @@ -72,8 +72,8 @@ Device (DPTF_CPU_DEVICE) Method (_TSD) { - If (CondRefOf (\_PR.CP00._TSD)) { - Return (\_PR.CP00._TSD) + If (CondRefOf (\_SB.CP00._TSD)) { + Return (\_SB.CP00._TSD) } Else { Return (Package () { @@ -84,8 +84,8 @@ Device (DPTF_CPU_DEVICE) Method (_TDL) { - If (CondRefOf (\_PR.CP00._TSS)) { - Store (SizeOf (\_PR.CP00._TSS), Local0) + If (CondRefOf (\_SB.CP00._TSS)) { + Store (SizeOf (\_SB.CP00._TSS), Local0) Decrement (Local0) Return (Local0) } Else { @@ -112,8 +112,8 @@ Device (DPTF_CPU_DEVICE) Method (_PSS) { - If (CondRefOf (\_PR.CP00._PSS)) { - Return (\_PR.CP00._PSS) + If (CondRefOf (\_SB.CP00._PSS)) { + Return (\_SB.CP00._PSS) } Else { Return (Package () { @@ -128,8 +128,8 @@ Device (DPTF_CPU_DEVICE) /* Check for mainboard specific _PDL override */ If (CondRefOf (\_SB.MPDL)) { Return (\_SB.MPDL) - } ElseIf (CondRefOf (\_PR.CP00._PSS)) { - Store (SizeOf (\_PR.CP00._PSS), Local0) + } ElseIf (CondRefOf (\_SB.CP00._PSS)) { + Store (SizeOf (\_SB.CP00._PSS), Local0) Decrement (Local0) Return (Local0) } Else { -- cgit v1.2.3
