From ed6bda2818a8ce79a36f9e5a2e30f1be6299724a Mon Sep 17 00:00:00 2001 From: Derek Huang Date: Wed, 27 Jan 2021 17:01:00 +0800 Subject: soc/intel/tgl: Add configurable value for ConfigTdpLevel According to Tigerlake TDP specifications (doc #575683, table 4-2), TGL supports different TDP levels depends on CPU segement/package, IA Cores and graphics configuration. For example, UP3 4-Core GT2 suppots base TDP=28W, Configurable TDP-Down_1=15W and Configurable TDP-Down_2=12W. This configurable value can be used to select suitable TDP level Change-Id: I4242575807caac172b6cbe667839bf6c9241f3c5 Signed-off-by: Derek Huang Reviewed-on: https://review.coreboot.org/c/coreboot/+/50104 Tested-by: build bot (Jenkins) Reviewed-by: Tim Wawrzynczak Reviewed-by: Nick Vaccaro --- src/soc/intel/tigerlake/chip.h | 3 +++ src/vendorcode/intel/fsp/fsp2_0/tigerlake/FspmUpd.h | 9 +++++++-- 2 files changed, 10 insertions(+), 2 deletions(-) diff --git a/src/soc/intel/tigerlake/chip.h b/src/soc/intel/tigerlake/chip.h index d3062cc720..edc716064f 100644 --- a/src/soc/intel/tigerlake/chip.h +++ b/src/soc/intel/tigerlake/chip.h @@ -105,6 +105,9 @@ struct soc_intel_tigerlake_config { /* Common struct containing power limits configuration information */ struct soc_power_limits_config power_limits_config[POWER_LIMITS_MAX]; + /* Configuration for boot TDP selection; */ + uint8_t ConfigTdpLevel; + /* Gpio group routed to each dword of the GPE0 block.
