            Bug ID: 93762
           Summary: Entire system stutters every so often when running
                    proprietary game Minecraft
           Product: Mesa
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi

dmesg output when freezing occurs

I have noticed that it occurs every once in a while, randomly, while playing
the game, mostly when I am moving around/entering new areas where chunks have
not loaded. I remember a few past mesa releases behind the game would have an
insane amount of stutter (mesa 10.5 or so) whenever new chunks would load and I
am guessing this is still the same issue just not as dramatic. I have no clue
what info to provide you guys except to give you a dmesg output immediately
after the stutter occurs.

Forgot to mention I am on Arch Linux, kernel 4.3.3, mesa 11.1 and am using an
AMD 7950.

Thanks for the report. Did the messages

[43513.525167] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_set_sw_state
failed
[43982.380508] [drm:si_dpm_set_power_state [radeon]] *ERROR*
si_restrict_performance_levels_before_switch failed

occur at the same time as the stutter? That would point at a kernel problem.

No messages appeared on my screen, what I have noticed is that whenever this
freezing occurs, so does my entire system essentially (I can still hear audio
from Skype or Mumble but I can't interact with things)...however those messages
seem familiar..ahh I know. I think I have seen those messages occasionally show
up on my screen when I log out/log back in. I think I started getting this
since the 4.1 kernels....

I am not really sure what I can do to further help you but please let me know!


Although, this portion is offtopic. I have another machine with an AMD 6570 or
something and those messages would occasionally show up on Linux Mint 17.1 and
the kernel that one uses is 3.18.

Those messages would not be triggered by an application.  They can only be
triggered by manually changing the power state via sysfs or via a display
change event such as switching between single and multi display.

I think I have messed with the power state once by following the Arch Linux
wiki, though the wiki said the methods provided would not be permanent so it
isn't anything that I did right?

Are these errors responsible for the problems I am getting in OP?

Thanks again!

Please run the game with the environment variable
GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load,num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created
and attach a screenshot of the game window taken just after a freeze occurred.

Um, my Linux knowledge is limited with this. I have minecraft-launcher in my
/usr/bin folder, so what I did was I put the following in the terminal and hit
enter

/usr/share/minecraft/
GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load,num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created


The game loaded up but I don't know if what you want is working.

What do you normally run to start minecraft from the terminal?  I'll assume
it's just minecraft, but if it is different just replace that part.  Run:

GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load,num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created
minecraft

If it works, you should see a bunch of graphs appears on the screen.

That definitely did the trick, okay, thank you! I will play in the world and
take a screenshot once a stutter happens!

Oddly enough I can not seem to reproduce the bug. It appears to only ecounter
whenever I am playing with another player...which is also when I have Skype
open. Interesting..maybe Skype was the cause of this? I need to do some further
tests now.

--- Comment #11 from Timothy Arceri <t_arceri@yahoo.com.au> ---
Running applications in the background or networked game play will increase cpu
use. It's not unreasonable for this to cause stuttering on a lower end cpu.

Since there is not much else to go on here and radeonsi has received many
updates to reduce various types of cpu use since this was reported I'm closing
this bug for now.
