One per CPU core, all having identical values:
type = Processor
cur_state = 0
max_state = 3
runtime_enabled = disabled
runtime_status = unsupported
runtime_usage = 0
=> but should a working Kaveri provide a fifth, GPU-specific, cooling device?
That also make me think that overheat/hang happens consistently using
ffmpeg (and often using video/visioconf)
thinkpad_acpi parameters of interest are:
/sys/module/thinkpad_acpi/parameters/fan_control = N
/sys/bus/platform/drivers/thinkpad_hwmon/fan_watchdog = 0
/sys/devices/platform/thinkpad_hwmon/fan1_input = 0
"fan" module is not loaded during boot (!)
Manually loading creates nothing more than:
> /sys/module/fan/drivers/platform:acpi-fan
[and nothing specific inside dmesg]
Maybe related to this line in dmesg?
> [drm] Internal thermal controller without fan control
