            Bug ID: 201539
           Summary: AMDGPU R9 390 automatic fan speed control in Linux
                    4.19
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.19
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: 0xe2.0x9a.0x9b@gmail.com
        Regression: No

GPU: R9 390
Kernel module: amdgpu
Application (example): Rise of the Tomb Raider benchmark

In Linux 4.18 the fan speed of the GPU gradually adapts to GPU load. Maximum
pwm is 155 during the benchmark.

In Linux 4.19 the overall fan speed is lower (which is more silent than 4.18,
with maximum at 112) but the fan spikes to full speed (pwm=255) for 1-2 seconds
which is extremely loud.

The 4.18 and 4.19 kernels are using the same firmware.

I have exactly the same problem with my R9 290X. I tested on the 4.19.6 kernel.
The problem is still present, not how it is not solved. I have to use the 4.18
kernel.x, so as not to damage my graphics card.

I experience the same issue

4.18-20 kernel on Manjaro (amdgpu + opencl taken from amdgpu pro on 3 x R9
390). Everything works fine. Fan rpm increase with load (tested with stak-xmr
miner).

4.19-8-2 kernel: Rpm fans always on minimum setting. Once one of the gpus hits
95C, sudden bursts of 100% rpm occur (under 1s duration). Application has to be
suspended or hardware damage will occur

checked pwm1_enable which displays "1". Changing to "2" has no effect.
pwmconfig drives fans to 100% during config but is unable to provide control.

pwm1 reads different values (from 86 to 127) but fans don't appear to change
speed at all.

Does setting amdgpu.dpm=1 on 4.19 help?  The default dpm implementation changed
between 4.18 and 4.19.

amdgpu.dpm=1 produces black screen (unable to boot) in both 4.18 and 4.19.
Using amdgpu.dc=1 produces error and freeze on boot

Linux 4.20 behaves the same as Linux 4.19.

I found a solution for my problem and detailed it in the previous link.
My R9-290X now fully functions on 4.20.0

Comment 10 and 11 are not related to the reported fan control issue.

I am still seeing the same problem on a r290x with amdgpu driver (and the
correct firmware available in the initramfs) on 5.1.0-0.rc0.git4.2

I am also able to reproduce the fan control issue on an R9 290X with Fedora's
kernel 5.0.3-200.fc29.x86_64.

The fans on the card do not spin up until the temperature reaches 95C, at which
point they jump straight to 100%.

Same as comment 8, amdgpu.dpm=1 just gives me a blank screen at boot.

Reproducible on an R9 390 with kernel 5.1.6-arch1-1-ARCH using amdgpu driver.
Setting amdgpu.dpm=1 or changing amdgpu.dc does not have any effect.

Also, sensors does not report the current fan RPM:
amdgpu-pci-1d00
Adapter: PCI adapter
vddgfx:       +1.00 V  
fan1:             N/A  (min =    0 RPM, max =    0 RPM)
temp1:        +59.0°C  (crit = +104000.0°C, hyst = -273.1°C)
power1:       47.24 W  (cap = 230.00 W)

@Rudolf - Have you tried my solution in the link I provided above?  I'm on
5.1.6 mainline and have no issues whatsoever with R9-290X

@Alex Smith - I've got a liquid-cooled card so don't know if my solution solves
your fan problem but try following my steps in the link.

@Steffen - Try my steps in the link mate, it may solve your problem.  Alex
Ducher himself gave me the tip on fixing it.

As far as I understand, you had issues with firmware loading. However, firmware
is loading fine on my end:
[drm] Found UVD firmware Version: 1.64 Family ID: 9
[drm] Found VCE firmware Version: 50.10 Binary ID: 2

--- Comment #18 from Sean Birkholz (supasean@hotmail.com) ---
I am not a kernel developer and haven't done much programming as of late, so I
am not really in a position to actually test this hypothesis.  However - from
the bit of research I've done trying to figure this problem out for myself I
believe the following explains the overheating and burst of fan speed instead
of proper cooling behavior.

Here is my sensors bit from kernel 4.18.x - I have the R9-290.

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:           N/A  
fan1:           0 RPM
temp1:        +65.0°C  (crit = +120.0°C, hyst = +90.0°C)

Take note that this displays the proper critical and hysteresis values for my
card.  If you look at the post on comment 14 which is how sensors display the
crit/hyst value for kernels beyond 4.18.x you notice the critical value is
about 19x the temperature of the surface of the sun and the hyst value is
absolute zero.  These values are hard coded into kernel source code in some
file, forgive me as I do not recall where I saw the code snippet.  But I
strongly believe that correcting the values in the file or changing it to
detect proper crit/hyst values based on card will correct this issue.  I simply
do not have the means to do this, nor do I know how to submit kernel bug fixes
and hope someone with more experience could give it a shot and see if the
resulting kernel functions properly.

--- Comment #19 from Sean Birkholz (supasean@hotmail.com) ---
I've done a bit of digging and I've managed to get a proper hysteresis value to
appear in a 5.1.14 kernel built from source.

I now have this output from sensors:

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx:       +1.00 V  
fan1:             N/A  (min =    0 RPM, max =    0 RPM)
temp1:        +66.0°C  (crit = +104000.0°C, hyst = +90.0°C)
power1:       29.02 W  (cap = 208.00 W)

I don't know why proper values are not set automatically because I've found the
correct values in tons of source files but none of the #defines appear to be
used?  And much of the source doesn't appear to differ between 5.1.14 and
4.18.x

I modified (kernel src)/drivers/gpu/drm/amd/powerplay/inc/pp_thermal.h and
changed the values of -273150 to 90000.  This corrects the hysteresis value but
I'm still searching for where the critical temp value is actually set.

I *think* fixing these values may fix the fan problem because why would a fan
spin up if its nowhere near the critical or hysteresis values?  No need. 
Except when the critical value is 19x the temp of the sun, the card gets so hot
it protects itself by maxing the fans for a short burst.  That is my theory
anyway, hope to be able to test it soon but no promises.

To anyone who's still struggling with this, perhaps this would be of help:
I'm using this script (https://github.com/grmat/amdgpu-fancontrol) as a
service, with these params: 

TEMPS=( 65000 75000 80000 90000 )
PWMS=(      0   190   200   255 )

Perhaps someone could tweak this a little bit better, but this works for me.
My gpu still sounds like an airplane when I'm running a benchmark like
Unigine-Heaven, but at least fans are spinning now.

Having simular issues with 5.3.8-050308-generic 

when it starts happening this is being spammed in dmesg

amdgpu: [powerplay] 
                failed to send message 282 ret is 254


I loose write acess to 
/sys/class/drm/card1/device/hwmon/hwmon1/pwm1_enable

it is stuck on 2 , and runs the fans super low @ 20% causing the GPU to reach
thermalmelt down 96 deg when the fan will do blips of 100% 
my bios was modded to even have a minimum fan speed of 50% and even this is
being over written 

/sys/class/drm/card1/device/hwmon/hwmon1/pwm1
also can not adjust 



GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.ppfeaturemask=0xffffffff amdgpu.dc=1
amdgpu.gpu_recovery=1 amdgpu.cik_support=1 amdgpu.dpm=1 radeon.cik_support=0"


if I reboot it works for a little while allowing me to change GPU speeds and
fan speeds then .. I loose fan speed control and can not get it back off auto ,
which seems to be setup with fans speeds way too low 


 GL_RENDERER:   AMD Radeon R9 200 Series (HAWAII, DRM 3.33.0,
5.3.8-050308-generic, LLVM 9.0.0)
    GL_VERSION:    4.5 (Compatibility Profile) Mesa 19.3.0-devel (git-ff6e148
2019-10-29 bionic-oibaf-ppa)


if I disable amdgpu.dpm I can control the fans but then I can not do Auto GPU
speeds and can not manually do my speeds 


my only guess is the firmware being loaded by kernel is the place containing
the info for fan speeds ?

I think you hit the nail on the head 

amdgpu-pci-0100

the numbers used in the 
linux/drivers/gpu/drm/amd/powerplay
are correct as they are the values the bios uses 
but Linux is reading/using the values differently ...

hmm maybe not 
it lets me briefly access manual 


Found the following PWM controls:
   hwmon1/pwm1           current value: 68
hwmon1/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) y
hwmon1/pwm1_enable stuck to 2
Manual control mode not supported, skipping hwmon1/pwm1.

wish I knew what the heck keeps locking pwm1_enable to auto @ low speeds :@

from what I can work out the only difference between the kernel versions 
was they added extra thermal readings to support the newer cards with thermal
junction sensors 


{-273150,  99000},
{ 120000, 120000},

has been in their since Jan 2018 ... 

looks like its reading the max temp settings from the bios 
I will confirm this tomorrow I will flash a custom bios 

/torvalds/linux/blob/master/drivers/gpu/drm/amd/powerplay/inc/hwmgr.h


/* The temperature, in 0.01 centigrades, below which we just run at a minimal
PWM. */


so maybe it is thinking it can do 1000C ? 


anyhow as I don't want to run an altered bios as that would force fan 100% on
boot  , what I decided to do was rip out all of AMD's new thermal code ...

found them hard coded here for the R9 290 hawaii / Sea Islands chip sets 

so that will be a dirty way to get it to go 100% throttle sooner I'll set mine
to 85000 and see how it goes , hopefully the rest follows  


linux/drivers/gpu/drm/amd/amdgpu/ci_dpm.c


if (adev->asic_type == CHIP_HAWAII) {
                pi->thermal_temp_setting.temperature_low = 94500;
                pi->thermal_temp_setting.temperature_high = 95000;
                pi->thermal_temp_setting.temperature_shutdown = 104000;
        } else {
                pi->thermal_temp_setting.temperature_low = 99500;
                pi->thermal_temp_setting.temperature_high = 100000;
                pi->thermal_temp_setting.temperature_shutdown = 104000;

oh I love it they know the drivers file is crap 

anyhow it looks like the real issue is in the GPU driver 

fan speeds temps everything is in their , ofcause this would not be an issue if 
pwm1_enable  was NOT STUCK  ON AUTO 


#if 0
                /* XXX: need to figure out how to handle this properly */
                tmp = RREG32_SMC(ixCG_THERMAL_CTRL);
                tmp &= DPM_EVENT_SRC_MASK;
                tmp |= DPM_EVENT_SRC(dpm_event_src);
                WREG32_SMC(ixCG_THERMAL_CTRL, tmp);

apparently I was looking through kernel 4.7 code on my pc and not master
linux/drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c
looks like the new file name 

as they relocated ci_dpm.c to 
/home/aio/Programs/linux/drivers/gpu/drm/radeon/ci_dpm.c

another plan 

drivers/gpu/drm/amd/powerplay/hwmgr/hwmgr.c 

hwmgr->dpm_level = AMD_DPM_FORCED_LEVEL_AUTO;
        hwmgr_init_default_caps(hwmgr);
        hwmgr_init_default_caps(hwmgr);
        hwmgr_set_user_specify_caps(hwmgr);
        hwmgr_set_user_specify_caps(hwmgr);
        hwmgr->fan_ctrl_is_in_default_mode = true;

change to false to disable auto .. not like its going to be any worse for us 

then GPU's thermal system will run and you can actually manually run the fans 
but unsure if this will stop auto core speed power save features as well

success 

drivers/gpu/drm/amd/powerplay/hwmgr/hwmgr.c 

hwmgr->fan_ctrl_is_in_default_mode = false;

it will now boot up in manual mode


finally I have fan control "AMD_DPM_FORCED_LEVEL_AUTO"  
I am wondering just how "FORCED" that "AUTO" is meant to be ....

how ever once you put it back to "2" "AUTO" it takes control again ... and will
overwrite your "0" card control and "1" manual  

echo 2 >  /sys/class/drm/card1/device/hwmon/hwmon1/pwm1_enable 
don't do it unless you want to reboot with a hot GPU :P 



also the crit temp for "Sea Island" cards like my R9 290 is defiantly being
retrieved from 
drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c 

thermal_temp_setting.temperature_shutdown


if (hwmgr->chip_id  == CHIP_HAWAII) {
                data->thermal_temp_setting.temperature_low = 74500;
                data->thermal_temp_setting.temperature_high = 80000;
                data->thermal_temp_setting.temperature_shutdown = 98000;




and the fans still spin slow regardless how low I set it .. sooo .. somethings
broken ... so looks like I will be doing a custom kernel on every update for a
while now to disable AUTO fan control 

and for some reason AMD devs feel 120 deg is NORMAL for a GPU and users want
quite fans ... I give up ...

--- Comment #35 from Michael (lkbugs@deegan.id.au) ---
I discovered a workaround that works for my R9-290 and Debian 5.3.0 kernel:

  root@joyola:~# echo "2"
>>/sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable 
  root@joyola:~# echo "0"
>>/sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable 

pwm1_enable will still be 2 afterwards, but (after spinning the fans at max for
a bit) automatic fan control works for me. I also have to do the same
pwm1_enable prodding after resuming from suspend.

(If it matters, I boot with radeon.cik_support=0 amdgpu.cik_support=1
radeon.si_support=0 amdgpu.si_support=1 amdgpu.dc_log=1 amdgpu.gpu_recovery=1)

I still have the same brokenness as reported in comment 14 though.

after having good fan control for a few weeks
 5.4.2-050402-generic is now having a melt down back to trying to run the cards
@
 (crit = +104000.0°C, hyst = -273.1°C)

and this is whats got me stumped , it seems to go auto when it hits high temp ~
70 then starts dropping the fan speed I can exit a game set a high fan speed it
will sit their @ 60 deg for a good 20 mins with ~ 60% , decide to go back into
game .. hits 70 .. fan speeds keep dropping until its 20% and blipping 100% @
95 deg

I am very close to going back to liquid cooling ... or connecting the fan to a
manual speed controller ( if someone knows of a way I can still have the fan
connected dor driver control and monitoring with a manual device override for
PWM I am all ears , would it be safe for me to just use a thermostat to just
send voltage to the fan ? ie) 2x input power sources 



my guess base or asic  is what its reading now about to hack away at those

well its neither of those modules 
I should have looked at the files after I scanned for files containing 104000


I can not even force run the cards in performance mode anymore with 100% fan
speed stuck on 

if i could just find the setting to tell amdgpu / hwmon / powerplay what temp I
call hot this would be solved

Here is a slightly modified version of a fan control script, along with the
service to run it, from the Arch Wiki. I don't know what distribution you use
but hopefully this will at least get you started. Unfortunately it doesn't seem
like the kernel devs are interested in fixing this, so after a long time I just
had to use this kludgey solution.

1. Create a file with the following contents named "amdgpu-fancontrol" in
"/usr/local/bin" and make it executable.

--------------- Start amdgpu-fancontrol ---------------

#!/bin/bash

HYSTERESIS=6000   # in mK
SLEEP_INTERVAL=1  # in s
DEBUG=true

# set temps (in degrees C * 1000) and corresponding pwm values in ascending
order and with the same amount of values
TEMPS=( 40000  50000  65000 75000 80000 90000 )
PWMS=(      0  100     140   190   200   255 )

# hwmon paths, hardcoded for one amdgpu card, adjust as needed
HWMON=$(ls /sys/class/drm/card0/device/hwmon)
FILE_PWM=$(echo /sys/class/drm/card0/device/hwmon/$HWMON/pwm1)
FILE_FANMODE=$(echo /sys/class/drm/card0/device/hwmon/$HWMON/pwm1_enable)
FILE_TEMP=$(echo /sys/class/drm/card0/device/hwmon/$HWMON/temp1_input)
# might want to use this later
#FILE_TEMP_CRIT=$(echo /sys/class/hwmon/hwmon?/temp1_crit_hyst)
[[ -f "$FILE_PWM" && -f "$FILE_FANMODE" && -f "$FILE_TEMP" ]] || { echo
"invalid hwmon files" ; exit 1; }

# load configuration file if present
[ -f /etc/amdgpu-fancontrol.cfg ] && . /etc/amdgpu-fancontrol.cfg

# check if amount of temps and pwm values match
if [ "${#TEMPS[@]}" -ne "${#PWMS[@]}" ]
then
  echo "Amount of temperature and pwm values does not match"
  exit 1
fi

# checking for privileges
if [ $UID -ne 0 ]
then
  echo "Writing to sysfs requires privileges, relaunch as root"
  exit 1
fi

function debug {
  if $DEBUG; then
    echo $1
  fi
}

# set fan mode to max(0), manual(1) or auto(2)
function set_fanmode {
  echo "setting fan mode to $1"
  echo "$1" > "$FILE_FANMODE"
}

function set_pwm {
  NEW_PWM=$1
  OLD_PWM=$(cat $FILE_PWM)

  echo "current pwm: $OLD_PWM, requested to set pwm to $NEW_PWM"
  debug "current pwm: $OLD_PWM, requested to set pwm to $NEW_PWM"
  if [ $(cat ${FILE_FANMODE}) -ne 1 ]
  then
    echo "Fanmode not set to manual."
    set_fanmode 1
  fi

  if [ "$NEW_PWM" -gt "$OLD_PWM" ] || [ -z "$TEMP_AT_LAST_PWM_CHANGE" ] || [
$(($(cat $FILE_TEMP) + HYSTERESIS)) -le "$TEMP_AT_LAST_PWM_CHANGE" ]; then
    $DEBUG || echo "current temp: $TEMP"
    echo "temp at last change was $TEMP_AT_LAST_PWM_CHANGE"
    echo "changing pwm to $NEW_PWM"
    echo "$NEW_PWM" > "$FILE_PWM"
    TEMP_AT_LAST_PWM_CHANGE=$(cat $FILE_TEMP)
  else
    debug "not changing pwm, we just did at $TEMP_AT_LAST_PWM_CHANGE, next
change when below $((TEMP_AT_LAST_PWM_CHANGE - HYSTERESIS))"
  fi
}

function interpolate_pwm {
  i=0
  TEMP=$(cat $FILE_TEMP)

  debug "current temp: $TEMP"

  if [[ $TEMP -le ${TEMPS[0]} ]]; then
    # below first point in list, set to min speed
    set_pwm "${PWMS[i]}"
    return
  fi

  for i in "${!TEMPS[@]}"; do
    if [[ $i -eq $((${#TEMPS[@]}-1)) ]]; then
      # hit last point in list, set to max speed
      set_pwm "${PWMS[i]}"
      return
    elif [[ $TEMP -gt ${TEMPS[$i]} ]]; then
      continue
    fi

    # interpolate linearly
    LOWERTEMP=${TEMPS[i-1]}
    HIGHERTEMP=${TEMPS[i]}
    LOWERPWM=${PWMS[i-1]}
    HIGHERPWM=${PWMS[i]}
    PWM=$(echo "( ( $TEMP - $LOWERTEMP ) * ( $HIGHERPWM - $LOWERPWM ) / (
$HIGHERTEMP - $LOWERTEMP ) ) + $LOWERPWM" | bc)
    debug "interpolated pwm value for temperature $TEMP is: $PWM"
    set_pwm "$PWM"
    return
  done
}

function reset_on_fail {
  echo "exiting, resetting fan to auto control..."
  set_fanmode 2
  exit 1
}

# always try to reset fans on exit
trap "reset_on_fail" SIGINT SIGTERM

function run_daemon {
  while :; do
    interpolate_pwm
    debug
    sleep $SLEEP_INTERVAL
  done
}

# set fan control to manual
set_fanmode 1

# finally start the loop
run_daemon

--------------- End amdgpu-fancontrol ---------------


2. Create a file with the following contents named "amdgpu-fancontrol.service"
in /etc/systemd/system.

--------------- Start amdgpu-fancontrol.service ---------------

[Unit]
Description=amdgpu-fancontrol

[Service]
Type=simple
ExecStart=/usr/local/bin/amdgpu-fancontrol

[Install]
WantedBy=multi-user.target

--------------- End amdgpu-fancontrol.service ---------------

3. Here's how to enable, disable, and get the status of the fan control
service:

sudo systemctl enable amdgpu-fancontrol
sudo systemctl start amdgpu-fancontrol
sudo systemctl status amdgpu-fancontrol

aio@aio:~$ sudo pwmconfig

# pwmconfig revision $Revision$ ($Date$)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0 is acpitz
   hwmon1 is amdgpu
   hwmon2 is coretemp
   hwmon3 is it8620
   hwmon4 is it8792

Found the following PWM controls:
   hwmon1/pwm1           current value: 104
hwmon1/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n) y
hwmon1/pwm1_enable stuck to 2
Manual control mode not supported, skipping hwmon1/pwm1.

I was about to call it a day when I got your email notifications. The line it's
talking about is:

echo "$NEW_PWM" > "$FILE_PWM"

So it looks like the "$FILE_PWM" variable is not valid. Remember, you have to
change the variables under the comment "hwmon paths, hardcoded for one amdgpu
card, adjust as needed" to whatever your system requires. To debug the
variables I would execute the 4 lines that set HWMON, FILE_PWM, FILE_FANMODE,
and FILE_TEMP from terminal and see where things are going wrong. I have to go
now but I'll try to help you more tomorrow if you're still having problems. But
once you have those variables set correctly the script should work. Here's what
the service status output looks like on my system:

the file is correct .. and you can tell that because its reading the temp
"current pwm: 76"

error is because NOTHING is being allowed to edit pwm1_enable it is stuck on
auto so nothing can manually change pwm1



but if their is an error in my adjustments let me know 


# hwmon paths, hardcoded for one amdgpu card, adjust as needed
HWMON=$(ls /sys/class/drm/card1/device/hwmon/hwmon1)
FILE_PWM=$(echo /sys/class/drm/card1/device/hwmon/hwmon1/pwm1)
FILE_FANMODE=$(echo /sys/class/drm/card1/device/hwmon/hwmon1/pwm1_enable)

Your variables are set wrong. If your GPU is card1 they should be:

HWMON=$(ls /sys/class/drm/card1/device/hwmon)
FILE_PWM=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/pwm1)
FILE_FANMODE=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/pwm1_enable)
FILE_TEMP=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/temp1_input)


The "HWMON" variable is there to determine which actual hardware monitor is
being used because it can change whenever you boot. One time it could be
hwmon1, the next time hwmon3, etc. So you can't hard-code it as you're doing.
You have to use the $HWMON variable to set FILE_PWM, FILE_FANMODE, and
FILE_TEMP.

There is also the possibility to use question marks in the path:

/sys/class/drm/card?/device/hwmon/hwmon?

Thank you for mentioning that. If you only have one GPU that will indeed work.
I have multiple GPUs, one Nvidia and one AMD, so I have to hard-code the card.

Maybe you can use the PCI ID of the device:

FOUND=false
for CARD in /sys/class/drm/card?; do
  DEVICE="$(cat "$CARD/device/device")"
  if [[ "${DEVICE,,}" == 0x67b1 ]]; then
    FOUND=true
    break
  fi
done
$FOUND || exit 1
HWMON=$CARD/device/hwmon/hwmon?
echo $HWMON

Well, my system works great the way it is and I don't really have time to do
any further debugging or redesign. I'm just trying to help MasterCATZ get
things going. However that's another great way to determine where a specific
card is, thank you for the multiple great suggestions!

It's great to see so many people trying to help, we need more of that in Linux,
especially with Arch and its derivative distros. It's very irritating and
frustrating when I see experienced users simply tell others to "read the wiki",
or expect them to use Linux for two years before they can have a usable
installation.

In fact that kind of old, outdated, and downright mean attitude is one of the
reasons Linux still has such a low share of the desktop market. So whenever I
see someone who needs help I try to make it as easy as I can for them, and have
even been insulted numerous times by the cruel people who are angered that I
don't just tell others to get a PhD or something :)

--- Comment #50 from MasterCATZ (mastercatz@hotmail.com) ---
Thanks for correction, I was unsure if $HWMON knew to go to hwmon1

works until GPU hits 70 deg then something forces "pwm1_enable" to auto and
starts ramping the fan speed down until its 20% @ 90+ deg and bliping 100% @ 95
deg 



for now all I can do is run custom bios with 800 memory speed and 850 core and
keep toggling between standard and performance mode on to reset fan speed to
100% and redo that every time its drops back below 40% and set
/sys/class/drm/card1/device/hwmon/hwmon1/power1_cap to under 140w so the GPU
does not cook 

so unless its "Radeon Profile" doing something to get locked out I have no idea 

its fan profile should be 
over 70 deg 1:1 ratio 
under 60 deg 50%
under 50 deg 10%
under 40 deg 5%
under 20 deg 0%

any way to find out what is accessing pwm1_enable ?

Well, that's certainly quite bizarre. I wish I could think of something else
but I'm stumped. I've never experienced that problem on my system, and I don't
know why yours isn't allowing the write. Is it possible there was some error in
copying the script? It seems unlikely but that's all I can come up with at this
point. If you have somewhere I can send my actual script and service files I'd
be happy to send them to you. Otherwise I'm just out of ideas.

its been like this since mid  kernel 4's, just wish I knew whats locking that
file root has no permissions and it seems to activate @ 70 deg , which even if
i run the fan 100% will be reached unless I under clock 

amdgpupro just turns PC into a paperweight so I don't use that 
radeon drivers suck for any gaming  
amdgpu / mesa 
are what I need to use and its been like this since powerplay was introduced 

Ubuntu 18.04, and just upgraded it to 19.10 same issues 
currently using 5.4.2-050402-generic

GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.ppfeaturemask=0xfffd7fff
amdgpu.ppfeaturemask=0xffffffff amdgpu.dc=1 amdgpu.cik_support=1
radeon.cik_support=0"

featuremasks seem to make no difference 
maybe I should re - add 
radeon.si_support=0  amdgpu.si_support=1

as  in as radeon profile is showing radeonsi is in use ?, 
but I thought R9 290 were Sea Islands = amdgpu.cik_support=1 ?

It seems that since kernel 5.6 (or at least Debian's version thereof), I no
longer need to fiddle with
/sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable. The default value (1)
seems to do the right thing now. Progress!

Mind you, lmsensors is still unable to report fan speed, and gives nonsensical
values for crit/hyst temperatures. I have a feeling that further improvements
to power management may be possible too.

I was going to try and get a fancontrol script working, but I found the
following as I started to play around:

I got my results on Arch Linux's 5.7.12-arch1-1 kernel.  

On boot pwm1_enable is set to 1 (manual mode).  On 4.18.x it is normally set to
2 (automatic mode) iirc.  Changing this value to 2 does essentially nothing for
me and the fans do not spin up with increasing temp.  

However, I've found that running pwmconfig and not even answering the first
question (ie; I can just ctrl+c out) causes the automatic temp control to start
functioning.  So after you run pwmconfig, then change pwm1_enable to 2 and
everything works again.  So far it appears doing these two things gets me the
same functionality I had on 4.18.x and I can finally upgrade my kernel.  No fan
control script needed.

It is interesting to note, if you do these in the opposite order; set
pwm1_enable to 2 and then run pwmconfig, you must say yes to enabling manual
mode on the gpu's fan before they start functioning properly.  This also causes
the fan to run full speed (like pwm1_enable is set to 0) and you will need to
set 2 in pwm1_enable again.

I dont know what pwmconfig is modifying to cause pwm to work again... I wish i
knew so I could set that up with a script and not have to manually start it,
but this is good enough for now as I reboot rarely.  Maybe I can make a script
to use with systemctl when I'm not lazy.

Hi all!

I'm running a Radeon R9 290 with amdgpu.

I've had the same issue of pwm1_enable being set to MANUAL on boot, and then
being stuck to AUTO after switching to AUTO. I've had a quick browse of the
code and have a fix that seems to work for me.

See the attached patch for my fix/work-around.

Thoughts and explanations follow.

Some comments and questions on the code. My card seems to use the smu7_* code
for handling fan and power related functionality. I'm not sure if this is
correct, but it seems that MANUAL is simply the default state for the card at
boot, and the software (maybe on purpose? it's unclear) mirrors because there's
a variable called fan_ctrl_enabled which is never explicitly initialized, and
thus is default-initialized to false, which equates to MANUAL in the
get_pwm1_enable() logic, which again means you may set the fan speed manually.

For those who want to take a look themselves, this is roughly what happens when
you write 2 (auto) to pwm1_enable:

> amdgpu_pm.c: amdgpu_hwmon_set_pwm1()
> smu7_hwmgr.c: smu7_set_fan_control_mode()
> smu7_thermal.c: smu7_fan_ctrl_set_static_mode()
> smu7_thermal.c: smu7_fan_ctrl_start_smc_fan_control()
> 
> // Send PPSMC_StartFanControl with parameter FAN_CONTROL_TABLE
> smumgr.c: smum_send_msg_to_smc_with_parameter 
> smu7_thermal.c: hwmgr->fan_ctrl_enabled = true;

Note that fan_ctrl_enabled is now true. When reading pwm1_enable, this is the
value that's checked.

Now, this happens when we try to write 1 (manualy) to pwm1_enable again:

> amdgpu_pm.c: amdgpu_hwmon_set_pwm1_enable()
> smu7_hwmgr.c: smu7_set_fan_control_mode()
> smu7_hwmgr.c: smu7_fan_ctrl_stop_smc_fan_control
> 
> // Now, a so-called phm platform cap is checked
> // See hardwaremanager.h for its definition
> // Its description is simply "Fan is controlled by the SMC microcode."
> if (phm_cap_enabled(hwmgr->platform_descriptor.platformCaps,
>                       PHM_PlatformCaps_MicrocodeFanControl))
>               smu7_fan_ctrl_stop_smc_fan_control(hwmgr);

If the above check were to succeed, it would continue to send a smum message of
PPSMC_StopFanControl and set fan_ctrl_enabled = false, and we would be back in
MANUAL land. However, the PHM_PlatformCaps_MicrocodeFanControl cap is never
set. AFAICT, this cap is only ever set for vega12 and vega20 cards, in
vega20_processpptables.c and vega12_processpptables.c. It's checked in a bunch
of places for smu7, but never in a way that explicitly prevents manual fan
control once manual fan control is enabled, such as after boot.

Simply commenting out the check above fixed the problem for me, and I have seen
no strange side-effects yet. This makes sense to me; after boot, setting fan
speed manually works and the code responsible doesn't require the
MicrocodeFanControl cap to be set for that. However, I don't know what the
purpose of that cap is, whether the only reason for it being present in smu7
and elsewhere is a situation of copy-pasting skeleton code, or what.

From looking at vega10_hwmgr.c, it looks like vega10 (AMDGPU_FAMILY_AI, arctic
islands?) cards should have the same problem and I assume the same fix should
work, so I included it in the patch. It would be great if someone with an
arctic islands card (RX 400 series?) could test and confirm this.

Comments and feedback are very welcome.

patch to fix pwm1_enable being stuck to AUTO for some gpu smu7 and vega10

Seems to work fine for smu7 (AMD Hawaii PRO Radeon R9 290), needs testing for
vega10 (arctic islands).

seems a bit random for me 5.8.17-050817-generic 

sometimes I can spend weeks with fan control then all of a sudden I find it
hitting 100deg because it keeps spinning back down to 20% range 

for me this seems to happen when I am using multiple monitors, does not seem to
happen when using a single display however this could be related to memory
actually idling 


I will give your code a go and put it into auto mode , its summer here so
thermals are reached quickly I have GPU idling 300core 100 memory  @ 47.8%
manually this seems to keep it the same temp as the entire system 
just so the dreaded auto is not triggered or else memory goes 800 and fan drops
to 20's with the 100% blimps @ 95+ deg

This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

Found the following devices:
   hwmon0 is acpitz
   hwmon1 is amdgpu
   hwmon2 is k10temp
   hwmon3 is hidpp_battery_2

Found the following PWM controls:
   hwmon1/pwm1           current value: 122

Giving the fans some time to reach full speed...
Found the following fan sensors:
   hwmon1/fan1_input     current speed: 5499 RPM

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!

yes, you'll need to adjust the path for pre 5.10 kernels.

Of course, that makes sense! Should've realized that there must be 
correspondig logic for non-vega12/20 hardware.

If this patch works, are you going to submit it or should I? Afterall, 
you found it :)

Unfortunately, your patch leads to a stuck boot. There's some minor 
"corruption" visible on the bottom of the screen while still booting up, 
and then it gets stuck.

I don't think I mentioned this in the previous posts, but I tried 
setting this cap myself, but in the thermal init function instead of in 
the process pp tables one, which had the same effect.

The boot seems to be stuck completely, since I can't ssh into the box 
either. Any suggestions for debugging this crash caused by enabling the 
MicrocodeFanControl cap are appreciated.

After some quick testing, your latest patch seems to work great! And new code,
ie. something not just taken from the other families?

I'll try to get an RX 480 user to test this, but seems to work wonders for me.
A welcome change with this patch is that the default fan control mode at boot
is now 2/auto.

Thanks for your help with this! Very much appreciated.

It's pretty similar to other the code for other smu7 chips (tonga, polaris,
etc.).  Note that this change is not relevant to newer smu7 chips (rx480,
tonga, etc.).

Well, I'll have a read! And thanks anyways, I'll run this going forward, post
if there are issues and am looking forward to seeing this in mainline at some
point :)

So.. I was also testing this on my Sapphire R9 290 Tri-X OC. And it seems to
work pretty good. 

I noticed an oddity though. The first time I tried it, when I switched to
manual fan control, every time I wrote something to pwm1 after one second the
thing seemed to reset to the default speed. On subsequent reboots this didn't
seem to happen anymore.

Cool! This landed in 5.10. 

By the way, I was wondering, is there any way to override the default minimum
20~26% minimum speed value?
I see that MinimumPWMLimit and zero rpm only landed with later cards, but it
seems crazy that not even with a custom bios I can fix this.

--- Comment #72 from MasterCATZ (mastercatz@hotmail.com) ---
finally this summer the R9 290 GPU's will be manageable 

seems to be working , now I just have to find the old settings I changed when
trying to run it at higher rpm , @ 60deg and its doing 80%+ RPM
possibly it is now following my BIOS settings from when I was trying to force
higher RPM  when it kept trying to run under 20% 

my manual settings seem to get overwritten a second after setting them 
but at least I am not being locked out like before 


now if someone could solve the issue when it uses more power when running
multiple displays ( exactly the same monitors res / hz  )
 I can run the card single display under 10 watts plug in another display and
its over 50 watts idle

You can enable mclk switching with identical monitors by setting
amdgpu.dcfeaturemask=2
It's enabled by default in 5.11.

GRUB_CMDLINE_LINUX_DEFAULT="usbcore.autosuspend=-1 amdgpu.dcfeaturemask=2
apparmor=0 amdgpu.ppfeaturemask=0xfffd7fff amdgpu.ppfeaturemask=0xffffffff
amdgpu.dc=1 amdgpu.cik_support=1 radeon.cik_support=0 radeon.si_support=0
amdgpu.si_support=1"


I am running amdgpu.dcfeaturemask=2 ?
or are the other attempted featuremask's causing issues now ?


Kernel 5.10 is working perfectly 


I turned off fancontrol service and using "marazmista/radeon-profile"

it is following my fan curve perfectly with out being locked out 

it has been years since my R9 was not cooking from 20% fanspeed issue even with
the core set @ 300mhz / 100 mhz memory

An update. Now on 5.10.0-2-amd64.

Fresh boot, with amdgpu.dc=1, everything is mostly fine. pwm1_enable=2. Except
that after resuming from suspend, pwm1_enable=1 and pwm1=255, resulting in
maxxed out fans. Subsequently setting pwm1_enable=2 results in old buggy
behaviour (2000RPM until 96C). However, if I suspend and resume again, it
sometimes goes back to behaving!

amdgpu.dc=0 is a bit of a non-starter, as while fan speeds remain low, so does
performance.

In all cases temp1_crit and temp1_crit_hyst still have crazy values (104000000
and -273).

The later 390 series cards (Grenada Pro) were also affected by an inability to
set the correct fan speeds in 5.4.0. Because the cards would not run their fans
greater than 20% of their max RPMs under load, it did destroy at least one 390
when it ran without proper cooling at 105 C for an extended period of time.

This patch saved the other R390 card in the other machine. Thank you.

As of 5.11, it still reports temp1_crit and temp1_crit_hyst as 04000000 and
-273.15.
