This doesn't seem +to be a problem for most boards in the tree currently, but newer boards +(such as the T480) are reporting critical temperature errors on zone 1, +due to differences in the EC RAM layout (ie, TMP1 is not valid). + +To mitigate this issue with the T480 (and likely other newer boards), +only include the ACPI code for thermal zone 1 for boards which need it. +Explicitly select it for those boards based on ACPI dump analysis and +model similarity. + +Change-Id: Ic022f2e14b2cae74656c0ac85ba8410d50cdc9de +Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> +--- + src/ec/lenovo/h8/Kconfig | 4 ++++ + src/ec/lenovo/h8/acpi/thermal.asl | 3 ++- + src/mainboard/lenovo/t400/Kconfig | 1 + + src/mainboard/lenovo/t410/Kconfig | 1 + + src/mainboard/lenovo/t60/Kconfig | 1 + + src/mainboard/lenovo/x200/Kconfig | 1 + + src/mainboard/lenovo/x201/Kconfig | 1 + + src/mainboard/lenovo/x60/Kconfig | 1 + + 8 files changed, 12 insertions(+), 1 deletion(-) + +diff --git a/src/ec/lenovo/h8/Kconfig b/src/ec/lenovo/h8/Kconfig +index fbdca5f94a..c8626cc75b 100644 +--- a/src/ec/lenovo/h8/Kconfig ++++ b/src/ec/lenovo/h8/Kconfig +@@ -73,4 +73,8 @@ config H8_HAS_WWAN_GPIO_DETECTION + bool + default n + ++config H8_HAS_2ND_THERMAL_ZONE ++ bool ++ default n ++ + endif # EC_LENOVO_H8 +diff --git a/src/ec/lenovo/h8/acpi/thermal.asl b/src/ec/lenovo/h8/acpi/thermal.asl +index fa5a282f54..bf9b653e12 100644 +--- a/src/ec/lenovo/h8/acpi/thermal.asl ++++ b/src/ec/lenovo/h8/acpi/thermal.asl +@@ -130,7 +130,7 @@ External (\PPKG, MethodObj) + Name (_PR0, Package () { FPWR }) + } + } +- ++#if CONFIG(H8_HAS_2ND_THERMAL_ZONE) + ThermalZone(THM1) + { + /* Thermal zone polling frequency: 10 seconds */ +@@ -168,4 +168,5 @@ External (\PPKG, MethodObj) + Return (C2K(\_SB.PCI0.LPCB.EC.TMP1)) + } + } ++#endif + } +diff --git a/src/mainboard/lenovo/t400/Kconfig b/src/mainboard/lenovo/t400/Kconfig +index 85e580e30e..12fbcbdee6 100644 +--- a/src/mainboard/lenovo/t400/Kconfig ++++ b/src/mainboard/lenovo/t400/Kconfig +@@ -11,6 +11,7 @@ config BOARD_SPECIFIC_OPTIONS + select SOUTHBRIDGE_INTEL_I82801IX + select EC_LENOVO_PMH7 + select EC_LENOVO_H8 ++ select H8_HAS_2ND_THERMAL_ZONE + select H8_HAS_BAT_THRESHOLDS_IMPL + select H8_HAS_BDC_GPIO_DETECTION if !BOARD_LENOVO_R500 + select BOARD_ROMSIZE_KB_8192 if !BOARD_LENOVO_R500 +diff --git a/src/mainboard/lenovo/t410/Kconfig b/src/mainboard/lenovo/t410/Kconfig +index 9c78cb1741..6f18528824 100644 +--- a/src/mainboard/lenovo/t410/Kconfig ++++ b/src/mainboard/lenovo/t410/Kconfig +@@ -22,6 +22,7 @@ config BOARD_SPECIFIC_OPTIONS + select DRIVERS_LENOVO_HYBRID_GRAPHICS + select INTEL_GMA_HAVE_VBT + select MAINBOARD_USES_IFD_GBE_REGION ++ select H8_HAS_2ND_THERMAL_ZONE + select H8_HAS_BAT_THRESHOLDS_IMPL + select MAINBOARD_HAS_LIBGFXINIT + select DRIVERS_RICOH_RCE822 +diff --git a/src/mainboard/lenovo/t60/Kconfig b/src/mainboard/lenovo/t60/Kconfig +index 6d095943bd..f1221191da 100644 +--- a/src/mainboard/lenovo/t60/Kconfig ++++ b/src/mainboard/lenovo/t60/Kconfig +@@ -25,6 +25,7 @@ config BOARD_SPECIFIC_OPTIONS + select HAVE_CMOS_DEFAULT + select I945_LVDS + select INTEL_GMA_HAVE_VBT ++ select H8_HAS_2ND_THERMAL_ZONE + select H8_HAS_BDC_GPIO_DETECTION if BOARD_LENOVO_T60 || BOARD_LENOVO_R60 + + config MAINBOARD_DIR +diff --git a/src/mainboard/lenovo/x200/Kconfig b/src/mainboard/lenovo/x200/Kconfig +index 4aa1e2ce1e..148584ed5c 100644 +--- a/src/mainboard/lenovo/x200/Kconfig ++++ b/src/mainboard/lenovo/x200/Kconfig +@@ -10,6 +10,7 @@ config BOARD_SPECIFIC_OPTIONS + select SOUTHBRIDGE_INTEL_I82801IX + select EC_LENOVO_PMH7 + select EC_LENOVO_H8 ++ select H8_HAS_2ND_THERMAL_ZONE if BOARD_LENOVO_X200 + select H8_HAS_BAT_THRESHOLDS_IMPL + select H8_HAS_BDC_GPIO_DETECTION if BOARD_LENOVO_X200 + select NO_UART_ON_SUPERIO +diff --git a/src/mainboard/lenovo/x201/Kconfig b/src/mainboard/lenovo/x201/Kconfig +index 319f127ab6..e91ec3e642 100644 +--- a/src/mainboard/lenovo/x201/Kconfig ++++ b/src/mainboard/lenovo/x201/Kconfig +@@ -24,6 +24,7 @@ config BOARD_SPECIFIC_OPTIONS + select MAINBOARD_HAS_TPM1 + select INTEL_GMA_HAVE_VBT + select MAINBOARD_USES_IFD_GBE_REGION ++ select H8_HAS_2ND_THERMAL_ZONE + select H8_HAS_BAT_THRESHOLDS_IMPL + select H8_HAS_BDC_GPIO_DETECTION + +diff --git a/src/mainboard/lenovo/x60/Kconfig b/src/mainboard/lenovo/x60/Kconfig +index 33238ccbd8..edacdcf234 100644 +--- a/src/mainboard/lenovo/x60/Kconfig ++++ b/src/mainboard/lenovo/x60/Kconfig +@@ -16,6 +16,7 @@ config BOARD_SPECIFIC_OPTIONS + select EC_LENOVO_H8 + select DRIVERS_I2C_CK505 + select DRIVER_LENOVO_SERIALS ++ select H8_HAS_2ND_THERMAL_ZONE + select H8_HAS_BDC_GPIO_DETECTION + select HAVE_OPTION_TABLE + select INTEL_INT15 +-- +2.39.5 + |
