            Bug ID: 193981
           Summary: AMDGPU: R9 380 Fan rotates all the time (loud!)
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.9.7
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org

dmesg output

The fan of my "Sapphire R9 380 ITX" is really loud on Linux. 

cat /sys/class/hwmon/hwmon2/pwm1
reports that it runs all the time on
"94"

while 
sensors | grep amdgpu -A 3
tells me that its at 

amdgpu-pci-0100
Adapter: PCI adapter
temp1:        +31.0°C  (crit =  +0.0°C, hyst =  +0.0°C)

When I now set /sys/class/hwmon/hwmon2/pwm1 to 0, the tmp still stays at
31-34°C while "idle". So thats not a thing.


Before linux loads (UEFI-routines, grub) and on Windows the fan stays offline
unless there is enough load that it is needed. On linux the fan starts to
rotate on boot and keeps rotating all the time (on load it rotates faster).
at 41°C pwm1 goes up to 104

When you create bugs against amdgpu driver, use the latest kernel and mesa
code:
https://cgit.freedesktop.org/~agd5f/linux/?h=drm-next-4.11-wip
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

Problems might be fixed in the latest code.

Yaketty version of Oipaf ppa works with Debian testing Xfce that is the best
distribution. Manjaro is much more difficult to use. 


Are you sure it is the gpu fan? Disable cpufreq, cpu temp and fan handling the
kernel config and use the Bios to control these.

My computer with X4 845 and Gigabyte RX460 2GB with 2 fans is quiet.

Is there some kind of live-image? I just can not switch to another distro,
since I need to work with this computer.

> Are you sure it is the gpu fan? 
Yep. I can just write "0" to /sys/class/hwmon/hwmon2/pwm1 and its quiet.

This btw wasnt the case since the beginning.There was a Kernel and/or
linux-firmware release that brought this bug in. I just cant figure out wich
Version it was.

Linux 4.4.47 is quiet. So it has to be somewhere in between 4.5 - 4.8. Wasnt
there a fan/hwmon related work in 4.6? or .7?


4.10RC7 has no fix for this. Mesa/Xorg seems also not related here.

--- Comment #4 from Fabian <plusfabi@gmail.com> ---
Also maybe not related, but according to sapphire, on OS start, the fan will
rotate for a short time (short like 0.5s) at a higher speed, to remove some
dust.

Maybe the linux-hwmon taked this dust-removal speed as default value and keeps
it for the whole runtime?

In Windows it's that way: a short high rotation speed and then slow down to
almost?) 0.

No live images and for example today adg5f 4.11-wip kernel received 20 or so
patches. To test with Debian testing Xfce create a 15GB test partition with the
Gparted livecd.

Burn Debian netinstaller to a cdrw or usb memory:
http://cdimage.debian.org/cdimage/stretch_di_alpha7/amd64/iso-cd/
Choose Debian Desktop and Xfce in the installer. Use the Whisker menu plugin
along with the Weather plugin and remove the original applications menu. You
can configure Xfce freely, so make it suitable for your liking.

Install Amd firmware:
https://packages.debian.org/stretch/firmware-amd-graphics
With Synaptic install Gdebi. With Gdebi you can install downloaded .deb
packages easily. Give the root password when asked.

Latest mesa:
Oibaf PPA:
https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

PPAs with Debian, use case B:
http://www.webupd8.org/2014/10/how-to-add-launchpad-ppas-in-debian-via.html


Latest Amd driver
Use the command: git clone -b drm-next-4.11-wip
git://people.freedesktop.org/~agd5f/linux

The kernel configuration file of Debian Official kernel are available in /boot,
named after the kernel release. Copy the .config file to the linux directory.
Connect all your devices and run the command: make localmodconfig. You can use
the command make defconfig too for creating initial .config file. 

Use the command: make xconfig and check that you have enabled: Reroute Broken
IRQ, Virtualization KVM and 300Hz CPU timer, I also disabled Swap, Kernel
Debug, CPU Freq scaling , Cpu handling in Acpi, Used Bios to control CPU and
devices. In the drivers->graphics->amdgpu enable cik support for a gcn 1.1 gpu
and si support for a gcn 1.0 gpu.

With Synaptic, install kernel-package and fakeroot packages. 
Create debian kernel package:
export CONCURRENCY_LEVEL=4
fakeroot make-kpkg --initrd kernel_image

Install the kernel package with Gdebi. To make a custom kernel to boot, add a
line to /etc/initramfs-tools/modules:
unix
And run: sudo update-initramfs
Reboot.

kernel 4.4 did not have power management support enabled for your card so the
clocks and voltages were always left at the lowest levels.

fin4478@hotmail.com, this kind of comment is essentially noise and makes the
lives of those of us working with bug reports and fixing problems harder.
Please stop, thanks.

hello, i have the same bug. On my sapphire r9 380 itx, the fan seem to work at
100% from the loading of the kernel (no problem in bios and in grub stage).
T
he bug seem to occur since the 4.9 series. 
T
he archlinux usb key i use to downgrade my kernel have a 4.9.11 and i have to
remove my r9 380 in order to boot or my system hang.

The bug occur in the last kernel from the archlinux (4.10.4) too.

Maybe it's specific to this model. I have a sapphire r7 370 in this computer
with no fan problem and last week a sapphire 7870 ghz edition with no problem.

Can you bisect?

I can try. I've seen how to do on the wiki.
I will test the kernel 4.9.1 and the 4.11rc1 tomorrow.
It may be longto do all the bisect, it took nearly 40-50 min to compile.

I start to bisect.
My problem is, between the linux-git-4.8.r15051.g133d970e0dad and the
linux-git-4.9rc5.r369.g697ed8d03909 my system doesn't found my harddrive with
his UUID and refuse to boot. It's a bug found in the RC release.
Since the fan bug occur after the loading of the drive, i don't know if the fan
bug is present or not...

I continue to bisect but do you know to pass the UUID not found. Something to
do in the compile config maybe.

You could try to find the exact commit which fixed the harddrive detection (at
worst by bisecting it). If the fix is sufficiently simple you can apply at for
every bisection step. This makes bisection a bit harder but if the fix is easy
this should be doable even for non-developers.

--- Comment #14 from Michel Dänzer (michel@daenzer.net) ---
First of all, you can just run "git bisect skip" for any commits where you
can't test for the problem you're bisecting, for any reason. With luck, this
will allow git bisect to identify the regressing commit anyway. Even if not,
it'll provide a range of candidate commits, which can be further narrowed down
using Felix's technique.

Thank you. "git bisect skip" could be useful next time. To avoid the problem i
use "git bisect log" to-a-file and "git bisect replay" from-a-file.

So the result :

That the bad part if it's a firmware bug.
The sapphire r9 380 itx has only one fan and is shorter than any other r9 380.
So their bios/firmware may be specific...

I've check the code, so if i understand; to solve the problem on my computer i
have to rename tonga_smc.bin to tonga_k_smc.bin
If it works, it's a firmware problem.
