From 6452a9fcfc072f85101abf0f476e10c6727d6b69 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 11 Dec 2020 12:33:57 -0600 Subject: mb/purism/librem_mini: Adjust PL1/2 levels While the Librem Mini (v1/v2) are more than capable of higher PL1/2, they currently ship with a 40W power supply, so set PL1/2 accordingly to avoid power spikes above the PSU rating (which can result in unexpected showdowns/reboots) Change-Id: Ia7f89e885f1af29cbbb67d6fb844257ba2b87417 Signed-off-by: Matt DeVillier Reviewed-on: https://review.coreboot.org/c/coreboot/+/48586 Tested-by: build bot (Jenkins) Reviewed-by: Angel Pons --- src/mainboard/purism/librem_cnl/variants/librem_mini/devicetree.cb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/mainboard/purism') diff --git a/src/mainboard/purism/librem_cnl/variants/librem_mini/devicetree.cb b/src/mainboard/purism/librem_cnl/variants/librem_mini/devicetree.cb index 6b326f0c63..8fb84ce581 100644 --- a/src/mainboard/purism/librem_cnl/variants/librem_mini/devicetree.cb +++ b/src/mainboard/purism/librem_cnl/variants/librem_mini/devicetree.cb @@ -7,8 +7,8 @@ chip soc/intel/cannonlake # CPU (soc/intel/cannonlake/cpu.c) # Power limit register "power_limits_config" = "{ - .tdp_pl1_override = 25, - .tdp_pl2_override = 51, + .tdp_pl1_override = 15, + .tdp_pl2_override = 28, }" # Enable Enhanced Intel SpeedStep -- cgit v1.2.3
