    What is "cgn"?

    You should see my Italian, your English is just fine

    It's possible that some of the most fiddly power saving HW features aren't being used yet, so first thought would be the integrated GPU heating up the package. Not sure though, one of the devs closer to the power mgmt would have to jump in.

    AFAICS we might have used the R7 M360 model on different chips at different times, Oland in the past and Topaz today, not sure though.

    Iceland/Topaz has actually been available for quite a while so it's possible that it was actually launched last year as the 360 (in that case the 360 has always been Topaz).

    Anyways, if you go by chip ID that usually works.
    thanks, and what about temperatures of notebook? sometimes CPU temperature increse also to 70° while i'm using firefox (for example), but not always, now for example temperature is ok, infact is arount 50-55 and sometimes reach 60° (or little more, only for 1-2 seconds an then decrease again), furthermore now i've also tried to stressing CPU with 14tabs of firefox (one also with a youtube video 720p), and also glxgears running, but temperature is normal and CPU FAN is quiet.
    but other time also without youtube, also with less tabs opened (also only one) temperature increase a lot, and CPU FAN start increasing RPM.

    i don't know why with opensource driver sometimes i've this problem, catalyst/crimson are ok (never over 55°).

    AMDGPU is fine, performance are better than few months ago, low temperatures are lower than crimson (also 38° using battery), battery drain is similar.
    but i'm worried about high temperatures reached some times, also when pc isn't really stressed.

    sorry for my english, but i'm italian

    AFAICS the information you are finding is all correct, it's just that anything saying Oland was correct a few years ago while anything saying Topaz is correct today. Topaz replaced Oland recently as the standard add-on dGPU for laptops with Hybrid Crossfire.

    EDIT - actually pretty much everything in the game-debate page looks wrong. No idea where they got info from.

    Some people use GCN 1.0, 1.1, 1.2 while others use 1, 2, 3. We generally call them GFX6, 7, 8. The great thing about standards is that there are so many to choose from.
    thanks for answer, so there isn't problem if i use AMDGPU also for dgpu r7 m360? (ubuntu use this driver by default also for dedicated gpu).

    AMD as opposed to Intel and Nvidia has very poor informations about his products on his site

    yes i know, but this is the reason of my dubs.

    i've found another source that tell that r7 m360 is oland (GCN 1.0, so not currently supported by AMDGPU)
    http://anandtech.com/show/9236/amd-a...ok-video-cards
    so i don't know why lspci see that this gpu is Topaz, now i don't know if this is really Topaz or if it is Oland (lspci -vv tell me also that dedicated gpu is using AMDGPU kernel driver)


    i've upodated kernel to version 4.6 RC6 lowlatency, now i'm using powersave governor, and i'm using firefox form a lot of minutes, temperatures still around 40° (very good), with ondemand governor using firefox, temparatures seems not high, vary from 40 to 60 (but reach 60/60+ only for some seconds), now i'm using ondemand governor and temperature vary from 42° to ~55° (or little more, but isn't a problem if cpu reach 60/65 for some seconds, also windows reach 65° on IDLE).
    seems a very good results.
    i'll keep you up to date about temperatures

    EDIT: now with this command
    Code:
    sudo cat /sys/kernel/debug/vgaswitcheroo/switch
    i receive this output, and i can't change the status of DGPU
    Code:
    0:IGD:+:Pwr:0000:00:01.0
    1:DIS: :DynOff:0000:04:00.0
    i've searched info about DynOff status, but i haven't understand what is the mean, i think that is Dinamically powered (so is off when i not use and on when i use it), so in this way, if i don't force the use of the DGPU using PRIME=1, the DGPU power consume is zero??

    EDIT 2: i don't know if this can be useful, i'm using this parameter on /etc/default/grub
    Code:
    quiet splash i8042.dumbkbd amdgpu.powerplay=1 amdgpu.sched_jobs=64

    http://superuser.com/questions/54185...device-at-boot
    i've found using lspci -vv that dgpu is using amdgpu driver, and his ID is 04:00.0
    Code:
    04:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360] (rev ff) (prog-if ff)
        DeviceName: AMD Radeon (TM) R7 M260
        !!! Unknown header type 7f
        Kernel driver in use: amdgpu
        Kernel modules: amdgpu
    so following your link, i've tried give this command
    Code:
    sudo echo 1 > /sys/bus/pci/devices/0000\:04\:00.0/remove
    and i've received this output
    Code:
    killed
    so now i must add this rule to /etc/udev/rules.d?
    Code:
     
     ACTION=="add", KERNEL=="0000\:04\:00.0", SUBSYSTEM=="pci", RUN+="/bin/sh -c 'echo 1 > /sys/bus/pci/devices/0000\:04\:00.0/remove'"

    i've tried this command to see the status of DGPU, and i've seen that DGPU is powered
    Code:
    sudo cat /sys/kernel/debug/vgaswitcheroo/switch
    [
    Code:
    0:IGD:+:Pwr:0000:00:01.0
    1:DIS: :Pwr:0000:04:00.0
    after give this command
    Code:
    sudo echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
    DGPU turn OFF
    Code:
    0:IGD:+:Pwr:0000:00:01.0
    1:DIS: :Off:0000:04:00.0
    temperatures seem better now (with kernel 4.6RC5), i'll test more also stressing PC, now with firefox open, temperatures is 42/51° (better than catalyst/crimson, and a lot better than windows 10).

    EDIT: i've launched glxgears for some minutes.
    temperature after a while, reach 63/64° then CPU fan increase a bit RPM, and temperatures start decreasing (~55°)

    now i'll try to follow your link.
    thanks
