            Bug ID: 192921
           Summary: Low frame rates and unrecognized monitor after kernel
                    upgrade
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.10.0
          Hardware: x86-64
                OS: Linux
              Tree: Fedora
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: stevengruspier@gmail.com
        Regression: No

Before upgrading my kernel (4.8.16), there was always a problem where at boot
the refresh rate was too high, so my screen would flicker. I could only set the
refresh rate to 120Hz max without any flickering. This was due to a bug or
feature that had yet to be added to the kernel (was fixed in the DAL patched
unofficial kernel). 

After upgrading the kernel to 4.9.3 I noticed that on boot there was no
flickering at 144Hz anymore, but when trying to play games and videos there are
issues with low frame rates. I then went to the display menu to check settings
and noticed that the monitor now says "unknown". I installed 4.10.0 rc 3 from
the rawhide repo with the same results.

Distro: Fedora 25
GPU: ASUS Strix AMD R9 380 4GB
Monitor: MG278Q (2560 x 1440 @ 144Hz)

Please attach the dmesg output.

Can you bisect?

What does xrandr say about the mode, and what framerate does e.g. glxgears
report?

xrandr

Glxgears
[CODE]

2909 frames in 5.0 seconds = 581.332 FPS
2969 frames in 5.0 seconds = 593.634 FPS

I am using wayland, so what is the equivalent of the xorg log file?

dmesg shows that the amdgpu driver fails to initialize due to missing
microcode:

 amdgpu 0000:01:00.0: Direct firmware load for amdgpu/tonga_k_smc.bin failed
with error -2

You need updated firmware:

I have never had to deal with the firmware before. Where do I place them? Do I
need to recompile the kernel?

grab the latest firmware from the linux firmware git tree.  Then copy it to
where ever your distro stores it (usually /lib/firmware/amdgpu).  If you are
using an initrd, please make sure you've updated the initrd to include the new
firmware.  If you build the driver into the kernel image (rather than as a
module), you'll need to include the firmware in the kernel image as well.

Works now. Like you said, just needed to add the latest firmware to
/lib/firmware/amdgpu/ and then run mkinitrd
/boot/initramfs-4.9.3-200.fc25.x86_64.img 4.9.3-200.fc25.x86_64 --force. Still
not able to handle 144Hz, but works just as it did before the update to the
kernel.

Thanks for the help you two!
