This set creates a basic thermal zone, which reads the SOC temp via a direct register read in AML. It also adds an active cooling policy using a GPIO pin for fan control that can optionally be enabled/disabled by the user from the BDS.
With the fan enabled it should be possible to see the soc temp like: # sensors acpitz-acpi-0 Adapter: ACPI interface temp1: +57.6C (crit = +90.0C) and the fan state may be read/cycled with: /sys/bus/acpi/devices/PNP0C06:00/PNP0C0B:00/physical_node/thermal_cooling/cur_state Cc: Leif Lindholm <l...@nuviainc.com> Cc: Pete Batard <p...@akeo.ie> Cc: Andrei Warkentin <awarken...@vmware.com> Cc: Ard Biesheuvel <ard.biesheu...@arm.com> Cc: Samer El-Haj-Mahmoud <samer.el-haj-mahm...@arm.com> Jeremy Linton (3): Platform/RaspberryPi4: Add a basic thermal zone Platform/RaspberryPi4: Create ACPI fan object Platform/RaspberryPi: Add entry for user fan control Platform/RaspberryPi/AcpiTables/Dsdt.asl | 31 ++++++++ Platform/RaspberryPi/Drivers/ConfigDxe/ConfigDxe.c | 55 ++++++++++++++ .../RaspberryPi/Drivers/ConfigDxe/ConfigDxe.inf | 3 + .../RaspberryPi/Drivers/ConfigDxe/ConfigDxeHii.uni | 5 ++ .../RaspberryPi/Drivers/ConfigDxe/ConfigDxeHii.vfr | 17 +++++ .../RaspberryPi/Drivers/ConfigDxe/SsdtThermal.asl | 83 ++++++++++++++++++++++ Platform/RaspberryPi/Include/ConfigVars.h | 4 ++ Platform/RaspberryPi/RPi3/RPi3.dsc | 5 ++ Platform/RaspberryPi/RPi4/RPi4.dsc | 8 +++ Platform/RaspberryPi/RaspberryPi.dec | 1 + .../Bcm27xx/Include/IndustryStandard/Bcm2711.h | 2 + 11 files changed, 214 insertions(+) create mode 100644 Platform/RaspberryPi/Drivers/ConfigDxe/SsdtThermal.asl -- 2.13.7 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
