[Bug 960925] Re: cpu resources divided to graphic driver

[Atadam]

reinstalling proprietor driver results in recovery of trip_pont 69000 and
"sensors" detect after cooling lower temperature than 68°C (65)
increasing fan speed at
76°C
84°C
86,5°C ??? (cannot even guess where this one came from)

i do not believe that any of the temperatures are correct because heat build up and cooling are too quick
nevertheless proprietor driver has to go

After removal of proprietor driver fan speeds increase at
74°C
84°C

decrease at
79.5°C 
and after a long time (guess 7min) at
69°C to lowest speed

according to dsmeg fan is registered as cooling device 7
/sys/bus/acpi/devices/device:07/subsystem/drivers/fan/PNP0C0B:00/thermal_cooling/subsystem/thermal_zone0
trip_points registered there are the same as in 
/sys/bus/acpi/drivers/thermal/LNXTHERM:01/thermal_zone

48000
57000
75000
84000
92000
100000

Since I am not fluent with any programming stuff i can only guess what happens. There is a routine accessing and altering values that it should not alter. There is one sensor and one fan on my hp 625 and it is using values from hwmon.
Additional, altering the drivers results in changing sensor values and trip points. Though the routine doing all this rubbish has to be connected to this process. Whatever it is, it is altering setup procedures because only after restart the system is affected.
God am I happy that my cpu has only 55W.
To my understanding there should not be any routine overriding those values. I will repeat the procedure and compare dsmeg reports. If i find anything i post it here.

Thanks and best regards to all M.Peters

Title:
  cpu resources divided to graphic driver

Status in “acpid” package in Ubuntu:
  New

Bug description:
  Since we had this summer over 45°C and my Laptop did not overheat i was just surprised that after the latest kernel update my Laptop started to do an emergency shutdown now and then. My first try was to change the fan settings in the Bios and oops there is no such thing. Only a choice where you might keep the fan running (I never shut of) or you allow it to shut down if it pleases to do so.  No temperature adjustment. After reading a bit HP site i found that they have a algorithm for fan control and it is obvious that is intended to keep the laptop silent.
  Though silence is not my main trouble but a fresh fried cpu is. 
  Has anybody a idea how to overcome the HP silent treatment and get some adjustment to temperature settings by making the fan work earlier.
  sensors tells me the following but all my feeble attempts to find and adjust it failed so far.

  acpitz-virtual-0
  Adapter: Virtual device
  temp1:       +56.1°C  (crit = +108.0°C)                  
  temp2:       +23.4°C  (crit = +108.0°C)                  

  k10temp-pci-00c3
  Adapter: PCI adapter
  temp1:       +56.1°C  (high = +70.0°C, crit = +100.0°C) 

  I'm good with Horses not with bites (too many teeth).
