From b6730e03e203c320a11306e902d52e3fcad43fef Mon Sep 17 00:00:00 2001 From: Eran Mitrani Date: Fri, 20 Jan 2023 11:24:00 -0800 Subject: [PATCH] soc/intel/adl: remove DPTF from D-states list used to enter LPM The D-state list lists the devices with the corresponding D-state that the devices should be in, in order to enter LPM DPTF is not mentioned in Intel's document 595644 as one of the devices. This CL removes it to avoid an error seen after it was added to that table: "ACPI Error: AE_NOT_FOUND, While resolving a named reference package element - \_SB_.PCI0.DPTF (20200925/dspkginit-438)" TEST=Built and tested on anahera and saw the error is gone BUG=b:231582182 Change-Id: I00eddd7e4cc71a0c25e77ff53025dee5bf942de1 Signed-off-by: Eran Mitrani Reviewed-on: https://review.coreboot.org/c/coreboot/+/72199 Tested-by: build bot (Jenkins) Reviewed-by: Subrata Banik Reviewed-by: Tarun Tuli --- src/soc/intel/alderlake/acpi.c | 1 - 1 file changed, 1 deletion(-) diff --git a/src/soc/intel/alderlake/acpi.c b/src/soc/intel/alderlake/acpi.c index 1d92a61ad6..9e0e1bd06c 100644 --- a/src/soc/intel/alderlake/acpi.c +++ b/src/soc/intel/alderlake/acpi.c @@ -170,7 +170,6 @@ static struct min_sleep_state min_pci_sleep_states[] = { { SA_DEVFN_ROOT, ACPI_DEVICE_SLEEP_D3 }, { SA_DEVFN_CPU_PCIE1_0, ACPI_DEVICE_SLEEP_D3 }, { SA_DEVFN_IGD, ACPI_DEVICE_SLEEP_D3 }, - { SA_DEVFN_DPTF, ACPI_DEVICE_SLEEP_D3 }, { SA_DEVFN_IPU, ACPI_DEVICE_SLEEP_D3 }, { SA_DEVFN_CPU_PCIE6_0, ACPI_DEVICE_SLEEP_D3 }, { SA_DEVFN_CPU_PCIE6_2, ACPI_DEVICE_SLEEP_D3 },
