 Posted: Tue Sep 13, 2016 4:51 pm Post subject: Poor performance with games |
 |
|
I am quite a beginner with gentoo so this might as well be really simple things missing.
Let this output from xonotic serve as example:
| Code: | xonotic-glx -benchmark demos/the-big-keybench 2>&1 | egrep -e '[0-9]+ frames'
319 frames 51.2171841 seconds 6.2283783 fps, one-second fps min/avg/max: 4 7 9 (10 seconds) |
At these fps the game is hardly playable.
I have an intel core i7 laptop with Radeon R7 M370 graphics card. I am using the amdgpu drivers.
(/etc/portage/make.conf:)
| Code: | | VIDEO_CARDS="amdgpu radeonsi" |
I am using KDE plasma. My profile (from "eselect profile list") is:
"default/linux/amd64/13.0/desktop/plasma" |

Since you’re on a laptop with an i7 and an AMD GPU, I guess this is one of these dual GPU laptops… Are you sure you’re using the AMD GPU and not the Intel GPU? What does glxinfo say?
For dual-GPU laptops with Nvidia GPUs, there is primusrun or bumblebee that lets you use the secondary GPU, but I don’t know what you should use for AMD GPUs. |

| @Elaman: please make sure you read this wiki article; perhaps your user is not in the "video" group... |

The wiki article helped. There is one part that I don't have configured:
file: /etc/X11/xorg.conf.d/10-dri.conf
| Code: | Section "Device"
Driver "radeon"
EndSection
Section "dri"
Mode 0666
EndSection
|
Because xorg would give me the following error:
| Code: | Parse error on line 3 of section Device in file /etc/X11/xorg.conf.d/10-dri.conf
This section must have an Identifier line. |
- The drivers package is installed: "x11-drivers/xf86-video-amdgpu"
| Quote: | | perhaps your user is not in the "video" group... |
- The user is in the "video" group.
| Quote: | | Since you’re on a laptop with an i7 and an AMD GPU, I guess this is one of these dual GPU laptops… |
- Yes, it is a dual GPU laptop.

Just a quick remark, direct rendering: yes is not accurate anymore, and completely useless with dual gpu. Check out this example:
| Quote: |
glxinfo | grep render
direct rendering: Yes
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on AMD SUMO (DRM 2.43.0, LLVM 3.7.1)
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil,
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fog_distance,
GL_OES_fbo_render_mipmap, GL_OES_get_program_binary, GL_OES_mapbuffer,

The following Gentoo wiki articles may help too:
Please note that I don't have a Radeon card and that I haven't read those articles myself. |

Good point. In any case I already know that I don't have DRI in use, since introducing the following config file:
( /etc/X11/xorg.conf.d/10-dri.conf )
| Code: |
Section "Device"
Driver "radeon"
EndSection
Section "dri"
Mode 0666
EndSection |
Resulted in the error:
| Code: | Parse error on line 3 of section Device in file /etc/X11/xorg.conf.d/10-dri.conf
This section must have an Identifier line.

| Looks like that wiki page is totally wrong. That config file would be placebo if it worked, and what it does have is incorrect for your video card anyway. |

To have a complete Section Device the Identifier name must be unique
| Code: | Section "Device"
Identifier "Radeon"
Driver "radeon"
EndSection |
When a user is in the video group, the Section "dri" is facultative for him because being in the video group give read and write permissions. mode 0666 set the read and write permissions globally for all users even if they are not in the video group.
I think it is better to use the video group per user then the Section "dri" to set users permissions on Direct Rendering Infrastructure. Have-you try to use only the default Xorg configuration without any Xorg personnalisation?

Yes. This is what I get from glxinfo if I do that:
| Code: |
glxinfo | grep render
direct rendering: Yes
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.7, 256 bits)
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_packed_depth_stencil,
GL_ARB_conditional_render_inverted, GL_ARB_conservative_depth,
GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp,
GL_OES_fbo_render_mipmap, GL_OES_get_program_binary, GL_OES_mapbuffer, |
So, as expected, no DRM there.
I tried now the following configuration file:
| Code: | Section "Device"
Identifier "AMDGPU"
Driver "amdgpu"
EndSection
#Section "dri"
# Mode 0666
# EndSection
|
For which I get the following error (I attach part of the xorg log):

Have a look to /var/log/Xorg.0.log when you start X without any customisation. Check which module driver Xorg use by default. It may not be amdgpu. Like fturco, I have not an Amd/ati video card and I never ever use amdgpu, only radeon and fglrx several years ago.
How have-you compile the Linux kernel for video support? Which video support have-you enable? Have-you compile them in the kernel image itself or in modules? A lot of video drivers like amdgpu need to have all the firmware files they need in the Linux image itself if the video support have been compile in the kernel image [y].
If the support is compile in module and you use an initramfs, both amdgpu and the firmware files need to be in the initramfs.
Is all the firmware files the amdgpu need are installed? Check the dmesg command output to see if Linux complain about amdgpu missing firmware files. A command like
| Code: | | dmesg | grep -i -e amd -e drm -e firm -e micro |
should tell you which firmwares and microcodes the Linux kernel use and miss. To work on Xorg side, amdgpu must work on the Linux side first.

I would guess your issue is that
1. your GPU isn't yet supported (yet) by amdgpu driver, use radeon insted
2. your have a dual-gpu setup, and your display is connected to intel GPU
Running lspci or googling your laptop model could give an answer. You also could enable support for radeon and intel graphics and see if that helps, doing it will not do any harm. Just remove any xorg configuration files you made, X should pick the right driver for you. |

I switched to amdgpu because it's the other way around, M370 appears on the list (https://wiki.gentoo.org/wiki/Amdgpu) while it doesn't appear on the "radeon" list. I noticed this too late as I already tried enabling support for radeon and intel graphics. Later I re-did more or less everything from scratch following the steps in amdgpu wiki.

Definitely, I am guessing the same.
lspci shows both:

|
(...)

I am not liking the "permission denied" part of the Xorg log. It looks like I have wrong permissions on some files.

Elaman,
I guess you have an Intel/AMD muxless graphics system. If that the case, you can't use the Radeon card alone because it can't refresh the display.
Lets start right at the beginning. Tell us the make and model of your laptop then we can check out how the hardware is put together.
Also make friends with wgetpaste so you can put whole log files on the web and post a link to them here.

All the sources I have seen list M370 as Southern Islands (GCN 1.0). Reverse lookup with your lspci output gives pci id 1002:6600, and kernel sources confirm that your chip is supported by radeon. I would guess that the wiki is wrong. You can verify the pci id with lspci -nn. In any case there is no harm enabling both radeon and amdgpu in kernel and VIDEO_CARDS. Both kernel and X should pick the right driver for you, and that's actually how most distros, including gentoo installation media, work. |
