From b138a8eb856dc9201dc2a80f0170a98078485d1f Mon Sep 17 00:00:00 2001 From: Kevin Chiu Date: Mon, 20 Dec 2021 14:19:56 +0800 Subject: mb/google/guybrush/var/nipperkin: update telemetry settings Update the two load line slope settings for the SVID3 telemetry. AGESA sends these values to the SMU, which accepts them as units of current. Proper calibration is determined by the AMD SDLE tool and the Stardust test. vdd scale: 73457 -> 73331 vdd offset: 291 -> 1893 soc scale: 30761 -> 31955 soc offset: 834 -> 852 BUG=b:207299255 BRANCH=guybrush TEST=1. emerge-guybrush coreboot 2. pass AMD SDLE/Stardust test Change-Id: I9c9dd4883fd21a70a1e7a50f25a4f76df1e56bc6 Signed-off-by: Kevin Chiu Reviewed-on: https://review.coreboot.org/c/coreboot/+/60243 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel Reviewed-by: Rob Barnes --- src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb') diff --git a/src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb b/src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb index 19c6fe1a43..c7917ae201 100644 --- a/src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb +++ b/src/mainboard/google/guybrush/variants/nipperkin/overridetree.cb @@ -61,10 +61,10 @@ chip soc/amd/cezanne register "sustained_power_limit_mW" = "15000" register "thermctl_limit_degreeC" = "100" - register "telemetry_vddcrvddfull_scale_current_mA" = "73457" #mA - register "telemetry_vddcrvddoffset" = "291" - register "telemetry_vddcrsocfull_scale_current_mA" = "30761" #mA - register "telemetry_vddcrsocoffset" = "834" + register "telemetry_vddcrvddfull_scale_current_mA" = "73331" #mA + register "telemetry_vddcrvddoffset" = "1893" + register "telemetry_vddcrsocfull_scale_current_mA" = "31955" #mA + register "telemetry_vddcrsocoffset" = "852" # I2C Config #+-------------------+---------------------------+ -- cgit v1.2.3
