            Bug ID: 110856
           Summary: Freesync causes in-game blackscreens when game has low
                    fps.
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mokurai82@gmail.com

When I play games on my Benq EX2303R 144hz monitor, the monitor shows
blackscreens/turns of for a few seconds in low fps scenarios like in-game menus
or during stutters. This is probably when the monitor exits it's VRR window.
Freesync is working normally with the same hardware and software but an Acer
XG270HU Freesync 1 monitor.

I have The following hardware:
an ASUS Strix Vega 64 8GB GPU
Benq EX3203r Freesync 2 Monitor
Lindy premium displayport cable.
Ryzen 7 1800x Stock clocks with SMT

Software:
MESA - 19.0.4-1
Operating System: Manjaro Linux 
KDE Plasma Version: 5.15.5
KDE Frameworks Version: 5.58.0
Qt Version: 5.12.3
Kernel Version: 5.2.0-1-MANJARO
OS Type: 64-bit
Processors: 16 × AMD Ryzen 7 1800X Eight-Core Processor
Memory: 15,7 GiB of RAM

These are the log files during Rocket League with VRR enabled.
I recorded these with kernel version 5.1.4-1-MANJARO as the 5.2 kernel is not
finished yet. If You need these with kernel 5.2-rc4 then I can also send them
too.

--- Comment #7 from Ropid <rropid@gmail.com> ---
I saw the same issue when I tried the BenQ EX3203R for a few days. I could work
around the problem by extracting and saving the monitor's EDID in a file, and
changing the VRR range in that file from the original 24-144Hz to 48-144Hz. I
then overrode the monitor's EDID on the kernel command line with this parameter
here:

drm_kms_helper.edid_firmware=DP-1:edid/edid-benq-xr3203r-vrr-48-144.bin

My customized EDID file is this:

$ base64 /usr/lib/firmware/edid/edid-benq-xr3203r-vrr-48-144.bin 
AP///////wAJ0WZ/RVQAABkcAQS1Rid4P901rE9FrCYQUFQlSwDR/NHo0cCzAKnAgYCBAIHAVl4A
oKCgKVAvIDUAgGghAAAaAAAA/QAwkN7ePAEKICAgICAgAAAA/ABCZW5RIEVYMzIwM1IKAAAAEAAA

AAAeB4KAUHA4TUAIIPgM4A4RAAAcAAAAAAAAqw==

If you want to try this custom EDID file I used, run that base64 encoded text I
shared here through "base64 --decode > filename.bin" to get the binary file.

For the kernel parameter, the output ports are named differently than in Xorg.
You can get the output port name where the monitor is connected like this:

$ grep . /sys/class/drm/card*-*/status
/sys/class/drm/card0-DP-1/status:connected
/sys/class/drm/card0-DP-2/status:disconnected
...

About how I created the EDID file, it was with a Windows tool named "Custom
Resolution Utility". It can extract the EDID from the monitor/driver and save
it in a file, and can customize the VRR data structure in there.

I only tried 48Hz for minimum VRR range and this worked fine, there were no
black screens anymore. I don't know what other values work with the EX3203R.

I've tried it but it did not work. I made a custom edid.bin file through CRU on
windows, but in rocket League when I click on menus the screen resets/flashes
black (as in the monitors hardware does). Also when I select the frame rate
target below the vrr window it stays black. It does happen less in in-game 3d
scenes I think, but that may be subjective. This happens all the time in
Witcher 2.
I've been on this for hours. I also tried advice from the following sites later
on:
https://forum.manjaro.org/t/solved-setting-custom-resolution-for-second-monitor-via-xorg-conf/83693/18

https://kodi.wiki/view/Creating_and_using_edid.bin_via_xorg.conf#Configure_xorg_to_read_custom_EDID_file

I of course adjusted it for amdgpu purposes.

I've tried these settings in /usr/share/X11/xorg.conf.d/10-amdgpu.conf 
according to those tutorials:

Section "OutputClass"
        Identifier "AMDgpu"
        MatchDriver "amdgpu"
        Driver "amdgpu"
EndSection
Section "Device"
    Identifier "AMD"
    Driver "amdgpu"
    Option  "ConnectedMonitor" "DP-2"
    Option  "CustomEDID" "DP-2:/etc/X11/edid.bin"
    Option  "IgnoreEDID" "false"
    Option  "UseEDID" "true"
    Option  "VariableRefresh" "true"
    Option  "TearFree" "on"
    Option  "DRI" "3"
#    Option "AccelMethod" "glamor"
EndSection

Those Xorg config options you tried to use do not exist on the
xf86-video-amdgpu driver (I mean "CustomEDID" etc.). Those EDID options you
used are unique Nvidia driver config options and do not exist in any other
driver.

If you are intersted, you can find a list about possible Xorg options for
amdgpu by running "man 4 amdgpu", and then there's more general stuff
documented in "man xorg.conf". There is sadly nothing about EDID anywhere.

For the open drivers that use kernel-mode-setting, you need to tell the driver
about your EDID file on the kernel command line. That's the only way to do it.

In the /etc/mkinitcpio.conf file you shared, you made a mistake on the
"MODULES=..." line. You need to remove that "drm_kms_helper..." text from that
line. That text you added there has to go onto the kernel command line, not
into mkinitcpio.conf.

The only thing you have to do in /etc/mkinitcpio.conf is what you already did
on the "FILES=..." line.

About that "drm_kms_helper..." kernel command line parameter, where you have to
add it is your boot loader's configuration file. I don't know how that works on
Manjaro.

Alright! The workaround is now working. To summarize:
All I needed to do is put the custom edid.bin file (that i made on windows with
the custom resolution utility with the minimum VRR set to 48 instead of 24) in
/lib/firmware/edid
Then edid /etc/default/grub with the following line:
GRUB_CMDLINE_LINUX_DEFAULT="drm.edid_firmware=DP-2:edid/edid.bin quiet" 
(You need to change DP-2 to whatever you get with  "grep .
/sys/class/drm/card*-*/status" )
After that I did "sudo update-grub" and rebooted the machine.

It's working flawlessly :) The upside of this method is that it is permanent.

Thank You for Your time and effort to help me Nicholas! Your pointers were
priceless!

Also I don't know if it's feasible but it would be nice if this workaround
wouldn't be needed in the first place.
