High cpu temperature and fan when loading i195 kernel module

[Luca Franchini]

Hi all,

I'm trying dragonfly on my new Thinkpad T460p (Intel HD 530 + Nvidia GPU).

Loading i195 kernel module seems to produce high cpu stress.

Before:

hw.acpi.cpu.cx_lowest: C1
hw.acpi.cpu.cx_lowest_use: C1
hw.acpi.cpu.px_dom0.avail: 2600 2500 2300 2200 2100 2000 1800 1700
1600 1400 1300 1200 1100 900 800
hw.acpi.cpu.px_dom0.power: 45000 42708 38257 36095 33977 31907 28288

hw.acpi.cpu.px_dom0.members: cpu7(900) cpu6(900) cpu5(900) cpu4(900)
cpu3(900) cpu2(900) cpu1(900) cpu0(900)
hw.acpi.cpu.px_dom0.select: 800
hw.acpi.cpu.px_global: 2600
hw.acpi.cpu.px_handle_notify: 1
hw.ncpu: 8
hw.sensors.cpu0.temp0: 37.00 degC (node0 core0 temp), OK

hw.sensors.cpu3.temp0: 37.00 degC (node0 core3 temp), OK

hw.sensors.cpu7.temp0: 37.00 degC (node0 core3 temp), OK
hw.sensors.cpu_node0.temp0: 38.00 degC (node0 temp), OK


Right after i915 is loaded:

hw.acpi.cpu.cx_lowest: C1
hw.acpi.cpu.cx_lowest_use: C1
hw.acpi.cpu.px_dom0.avail: 2600 2500 2300 2200 2100 2000 1800 1700

26331 24415 20707 19297 17535 15813 12486 10879

hw.acpi.cpu.px_handle_notify: 1
hw.ncpu: 8
hw.sensors.cpu0.temp0: 60.00 degC (node0 core0 temp), OK
hw.sensors.cpu1.temp0: 48.00 degC (node0 core1 temp), OK
hw.sensors.cpu2.temp0: 49.00 degC (node0 core2 temp), OK
hw.sensors.cpu3.temp0: 46.00 degC (node0 core3 temp), OK

hw.sensors.cpu7.temp0: 46.00 degC (node0 core3 temp), OK
hw.sensors.cpu_node0.temp0: 60.00 degC (node0 temp), OK


By the way, X display is working... :-)
