Low-overhead client-side GPU offloading

primus

Primus is a shared library that provides OpenGL and GLX APIs and implements low-overhead local-only client-side OpenGL offloading via GLX forking, similar to VirtualGL. It intercepts GLX calls and redirects GL rendering to a secondary X display, presumably driven by a faster GPU. On swapping buffers, rendered contents are read back using a PBO and copied onto the drawable it was supposed to be rendered on in the first place. For more information, refer to [technotes.md] (https://github.com/amonakov/primus/blob/master/technotes.md).

To use, install or build from source and use primusrun wrapper script.

In distributions

• Arch: primus-git and lib32-primus-git in AUR
• Gentoo: primus-9999.ebuild in the bumblebee overlay
• Ubuntu: in the Bumblebee PPA

Building for multilib (32-bit + 64-bit) systems

LIBDIR=lib make && CXX=g++\ -m32 LIBDIR=lib32 make

Adjust LIBDIR variables above as appropriate for your distribution (reflecting how /usr/lib* are named):

• Arch needs lib and lib32 as above

• Gentoo needs lib64 and lib32

• RPM-based may need lib64 and lib

• Debian (with multiarch) needs lib/x86_64-linux-gnu and lib/i386-linux-gnu

• Ubuntu (with multiarch) seems rather inconsistent. The dynamic linker expands $LIB to x86_64-linux-gnu/i386-linux-gnu (without lib/), but Nvidia drivers are installed into /usr/lib{,32}/nvidia-current. Something like the following is needed:

    export PRIMUS_libGLd='/usr/lib/$$LIB/mesa/libGL.so.1'
    LIBDIR=x86_64-linux-gnu make
    LIBDIR=i386-linux-gnu CXX=g++\ -m32 make
    unset PRIMUS_libGLd
  

  Starting from 13.04, Ubuntu needs the same LIBDIR paths as Debian (with leading lib/); consequently, lib/ in PRIMUS_libGLd should be omitted.

  Furthermore, libnvidia-tls.so is not present in default shared library search directories. Uncomment the corresponding line in primusrun.

Issues under compositing WMs

Since compositing hurts performance, invoking primus when a compositing WM is active is not recommended. If you need to use primus with compositing and see flickering or bad performance, synchronizing primus' display thread with the application's rendering thread may help (can anyone investigate why?):

PRIMUS_SYNC=1 primusrun ...

This makes primus display the previously rendered frame. Alternatively, with PRIMUS_SYNC=2 primus will display the latest rendered frame, trading frame rate for reduced visual latency.

FAQ

Q: Performance does not exceed 60 fps, I was getting more with optirun/VirtualGL.
A: This is the effect of vblank synchronisation. For benchmarking, you can use vblank_mode=0 primusrun ..., but in practice this will probably only waste power, as your LCD panel does not display more than 60 frames per second anyway.

primus's Issues

Fullscreen application is black 1 frame of 2 using kwin

it look like it render only 1 frmae of 2 using KWin with visual effect (CRender and Opengl). I checked the case "suspend effect on fullscreen window" and it didn't fix the issue. I tried some games like minecraft or bit.trip.runner and all of these appear to have this bug.

Slow performance and freezes running CoDMW

I get the following unexpectedly low frames per second reported by the CoDMW application (arcade mission 'War Pig') running at 1600x900 under Ubuntu 12.10 (see also comments on Bumblebee-Project/Bumblebee#241):

primus: 15-16 fps
optirun: 25-32 fps

and I get occasionally graphics freezes of 1-5 seconds where the video stops but the game continues running in the background (eg when video starts up again I sometimes have been shot).

primus does not report any profiling information for this application, and using PRIMUS_SYNC=1 (or 2) doesn't make any difference.

Looking at the CPU usage, it appears that under primus one of the cores is running at approx 40%, whereas under optirun it is running at around 90%.

I'm running on a 64 bit OS with primus's libGL.so.1 built for i386.

Firefox WebGL: segfault

If I try running firefox with primusrun, it looks fine, but if I load any page requiring WebGL or acces to the graphic cards, it segfaults, whereas it runs correctly with optirun (VGL).

The terminal output is just:
Segfault (core dumped)

No relevant output in Xorg.8.log, nor in syslog.

Is there anything usefull I can provide (something with gdb for example) ?

32bit apps on 64bit OS "primus: fatal: failed to acquire direct rendering context for display thread"

I can't run any 32bit games on my openSUSE 12.2 64bit with following error:
primus: fatal: failed to acquire direct rendering context for display thread
I think I did everything right, because 64bit games works ok. Also 32bit games works in optirun.
Please help.

TF2 crash with multicore rendering

When using primusrun, TF2 will crash with multicore rendering, randomly. It'll most likely crash at the end of the server connection, or when a player get killed. It works fine with optirun.

Thread backtraces from gdb:
http://pastebin.com/2FNucqzh

Here is an example console output after the crash:
intel_do_flush_locked failed: Erreur d'entrée/sortie
client callback thread error
client callback thread error

response: CrashID=bp-81532fb9-5676-4c88-99e8-ac93a2121206

The first line can be translated as:
intel_do_flush_locked failed: Input/Output error

And this crash my desktop environment (cinnamon), I am unable to restart it, if I try to, it will always print the same error (intel_do_flush_locked failed: Input/Output error) and just close. I could restart it by making it run on the nvidia card with "optirun cinnamon" though.

I am running Ubuntu 12.10, Nvidia 310.19 driver with the xorg-edgers PPA.

If I disable multicore rendering (mat_queue_mode 0), everything works fine though, but I get lower framerates.

do you need more information?
It would be nive to know which system you are using, so it is easier to find for errors, because on your system it seems to work.

Can't run primus with nvidia-experimental-310.

Hello,

I tried to run primus with nvidia-experimental-310 but I failed.
I changed PRIMUS_libGLa to: '/usr/lib/nvidia-experimental-310/libGL.so.1:/usr/lib32/nvidia-experimental-310/libGL.so.1', and tried to fire up primusrun.

primusrun glxgears

I don't know where the problem is, but the library libnvidia-tls.so.310.14 is present in /usr/lib/nvidia-experimental-310/.

Any thoughts?

correct way to add primusrun to this sh file?

So trying to get all my steam games to run via primusrun:

Amnesia uses this it seems:

!/bin/sh

if [ arch == "x86_64" ]; then
./checklibs.sh libs64 Amnesia.bin64
./Amnesia.bin64
else
./checklibs.sh libs Amnesia.bin
./Amnesia.bin
fi

What would be the correct way to add the command?

Sometimes black screen while playing Team Fortress 2 on native Steam Client

Hey Guys,

I have a little problem while playing Team Fortress 2 on my Linux box.
First I have to say, that the problem doesn't exist, when playing with optirun command instead of primusrun.

Steps to reproduce:

1. Start Steam with
   $ primusrun steam
2. Play Team Fortress 2 for a while
3. After a while the screen will go black for 1-10 secs
4. After that the game will run normal for a few seconds
5. Again black screen

Cant seem to get primus working on fedora 16

After trying every way i can think of I cant get primus to work even though optirun works well.
Any help for my F16 installation would be greatly appreciated: For anyone who has gotten it to work – what were your exact steps to get it working?

I fullly updated everything and pulled the most recent copy of primus as of 12-16-2012:
removed old bbswitch and am now running 0.5, also running bumblebee 3.0.1
installed packages listed below – are there any others that should be installed or looked at?

995 frames in 5.0 seconds = 198.842 FPS
955 frames in 5.0 seconds = 190.843 FPS

oddly when primus cant find the primuslib it gets similar numbers to the intel i7 which indicates to me its falling back to the i7 which is confirmed in the nvidia-settings control panel looking at the gpu temp, clock speed and ram usage – the card is sitting idle. (also dmesg DOESNT show card starting up)

just running make in the primus directory seems to cause primus to use the intel i7 gpu. having tried every compile option i could think of, i cant seem to get primus to use the nvidia gpu at all. the config below is the closest i could get to working - it could see the usual pause to load the nvidia gpu but the glxgears window would flash for a split second before throwing the following error.

Using primus with nouveau

Hi,

How should I configure primus to run it with nouveau? If I switch bumblebee to nouveau, primus does not work anymore, saying NV-GLX is missing.

Looking at the way I've built primus, it looks like it's only compatible with nvidia proprietary driver. How could I build it for nouveau support, or better, for both support ?

Multisampling AA limited by iGPU capabilities

Couldn't get Freespace 2 working unless I turned down the AA to 4x. It will run, but flicker constantly. Optirun can handle 8x and 16x (ignoring framerate).

FXAA seems to work fine.

Bumblebee + primusrun

When using primusrun, Bumblebeed writes this to syslog:
bumblebeed[1000]: Could not read data! Error: Connection reset by peer

Is this an error on primus or Bumblebee side?

Slow performance on some video modes

I was getting consistent very slow performance on my Zenbook UX32VD (the FullHD one) of about 8-9 fps on 1920x1080 in Trine 2 - regardless of the game settings. I tried changing the resolution to others and still the performance was sub par. Then I discovered that if the resolution width was different than the standard resolutions (for instance if I set 1919x1079), FPS almost tripled to about 25. Same goes for lower resolutions.

Unfortunately this also affects fullscreen and I can't change the resolution there. Is this a known issue?

Front buffer updates/single-buffered rendering not supported

here is the source:
http://techpubs.sgi.com/library/tpl/cgi-bin/getdoc.cgi/0650/bks/SGI_Developer/books/OpenGLonSGI/sgi_html/ch03.html#LE40932-PARENT

it works with optirun and on intel.

[wine] black window in killingfloor

with a steam running in primus (with virtual desktop) I'm getting a black screen with killingfloor.

KillingFloor is running with OpenGL.

primus won't quit with bastion sometimes

after playing bastion for some time, primus won't quit bastion anymore (background sound is still played after quit).

I got this warning: "primus: warning: dropping a frame to avoid deadlock"

But sometimes I am getting also this error:
"X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 40 (X_TranslateCoords)
Resource id in failed request: 0x4000002
Serial number of failed request: 7050

but then bastion is closed

Packages for Ubuntu 12.10

I see your PPA only has Precise, any chance of packages for 12.10? Really dislike compiling it's quite confusing.

primusrun fails to set higher resolution than available (while optirun works)

If I set up CoD MW2 so that:

• winecfg is set to emulate a 1600x900 screen
• CoD MW2 is set up for 1920x1080

and then I try running CoD MW2 with primusrun, the game freezes when it tries to set the resolution. There are no errors from primusrun, and only this error from wine:

err:d3d:context_create wglSwapIntervalEXT failed to set swap interval 1 for context 0x173dc1f0, last error 0x591

However, if I run this using optirun, it works - I just lose the window borders.

primusrun fails on Ubuntu 13.04

I just updated to Ubuntu 13.04, and primusrun no longer works correctly.

primusrun glxgears give the following result:
Xlib: extension "NV-GLX" missing on display ":0".

TF2 gives an error about a missing extension.

It works fine if I do the following export though:
export PRIMUS_libGL=/usr/lib/x86_64-linux-gnu/primus/
(or i386-linux-gnu for TF2)

EDIT:

The problem might still be that $LIB is not working after all.

I could solve the problem by editing primusrun, and changing:
PRIMUS_libGL=${PRIMUS_libGL:-/usr/lib/'$LIB'/primus}
to
PRIMUS_libGL=${PRIMUS_libGL:-'/usr/lib/x86_64-linux-gnu/primus:/usr/lib/i386-linux-gnu/primus'}

Any idea why $LIB isn't working?

Why is the intel driver needed anyway? Primus should use the dedicated Nvidia graphic card, correct? Can anyone help?

Support multiple directories in PRIMUS_libGL{a,d}

Currently, you have to pass an absolute path (defined as "first character is a slash") to PRIMUS_libGL{a,d}. The 32/64-bit "problem" was solved by using /usr/$LIB/nvidia/libGL.so.1, but this also has issues.

On Ubuntu (as you mentioned in the README), $LIB gets expanded to x86_64-linux-gnu or i386-linux-gnu (https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/993955) instead of the usual lib32 and lib64. It isn't even consequent with library paths, e.g. /usr/lib32/nvidia-current/libGL.so.1 vs /usr/lib/i386-linux-gnu/libGL.so (note host triplet vs plain lib32 name).

To work around this issues, I propose to augment the PRIMUS_libGL{a,d} variables with support for multiple files (or directories in which case /libGL.so.1 is simply appended). These would then be separated by colons (:).

Furthermore, if the name passed to dlopen contains a slash (instead of "begins with a slash"), it is already interpreted as a relative or absolute path instead of a name to be searched. This could be changed while we are at it.

Thoughts?

Add OpenGL 3.x and 4.x support

Hi, I really like your work, but is it possible to add support for creating OpenGL 3.x and 4.x context?
In fact, I use OpenGL > 3.2 with VirtualGL, but I would use primus!

The problem: glXGetProcAddressARB( "glXCreateContextAttribsARB" ) return a NULL pointer :(
Can you add it?

X_GLXVendorPrivate not suppported?

Hi all!

I'm trying to run X-Plane by using primusrun, since it works well with Bumblebee and I would like to see if I could get some benefits from primus.

I've compiled from sources under Ubuntu 12.04, with Linux kernel 3.7 and a working bumblebee installation, using the instructions on the provided README file.
The test with glxspheres is working properly, however when I start xplane with this command line:

PRIMUS_libGL=${PRIMUS_libGL}:/usr/lib/nvidia-current:/usr/lib32/nvidia-current \
PRIMUS_SYNC=1 \
vblank_mode=0 \
primusrun ./X-Plane-i686

I'm getting this error:

Xlib:  extension "NV-GLX" missing on display ":0".
X Error of failed request:  GLXUnsupportedPrivateRequest
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  16 (X_GLXVendorPrivate)
  Serial number of failed request:  44
  Current serial number in output stream:  46

Do you have any clue on this error? Perhaps I'm missing something, or simply the require functionality if not supported by primus?

Thanks Patrick

N.B. I've noticed an interesting reduction of CPU load when running glxspheres with primusrun vs it running with optirun. That's seems really promising! ;-)

Bash completion

Is it possible to make bash completion available for primusrun? Even though primusrun doesn't actually take any options, it's still handy to be able to auto-complete commands, just like when using optirun. Thanks!

amd/intel setup

Hello,
I am trying to use primus with intel/amd setup:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Madison [Radeon HD 5000M Series]

I use open source radeon driver(xf86-video-ati 1:7.0.0).

• glxinfo works, seems like it returns vaild info: direct rendering yes, opengl version 3.0 (intel suports only 2.1)
• glxgears works.
• minecraft
  crashes with xmlconfig.c:1033: driQueryOptioni: Assertion cache->info[i].name != ((void *)` (which seems to be in mesa)
• unigine-heaven (oilrush):
  works! fps rises from 5 (intel) to 17.
• simple opengl test from qtcreator examples(slightly modifed to use shaders):
  QGLShaderProgram: shader programs are not supported

Not finding libGl or libnvidia-tls on Fedora

Currently trying to compile on Fedora, though I've also had problems with the openSUSE package that is provided in rpm form.

As the readme states my two lib directories are lib64 and lib, I changed that so that the command reads:

mesa is loaded by runtime dlopen calls

primus doesn't work with libGL.so loaded by dlopen calls.

this could be solved with an overwritten dlopen function within primus itself. Because in general I don't like this idea, we should find other ways to handle this.

This occurs for many important libraries, for example wine, mono and SDL.

I will build a little demo for this issue later.

Games occasionally showing black screen only

Amnesa is not always starting properly when using primusrun: Every once in a while (usually only the first time I try after booting the machine), the entire screen is blacked out. After some time, I can hear the menu sound, but nothing is shown. I have to switch to a vtty and kill it from the outside.
The primus output shows that all (or at least, really many) frames are "dropped to prevent deadlock". There's not a single line reporting display fps, but there are a bunch of render fps lines.

I've also seen TrackMania (in wine) showing the same behaviour once, but did not check the primus output then - and I never saw that before. I don't know if that was the same issue.

World of Warcraft under Wine with the opengl renderer fails to detect compatible graphics card

Hi,
Running WoW under wine with the opengl renderer (with the -opengl commandline argument) with primusrun results in the game giving the following error: "
Your 3D accelerator card is not supported by World of Warcraft. Please install a 3D accelerator card with dual-TMU support."

The game's d3d renderer works just fine, and with optirun both renderers work fine.
Amonakov asked on IRC that I add the output of "strings -a Wow.exe | grep -i wgl"
so here it is: pastebin.com/KXtZitr9

Primus and VirtualBox update

Hi there. I just read Bumblebee-Project/Bumblebee#278 and was testing some things based on that discussion. I noticed via dmesg that bbswitch was powering up then quickly powering back down the Nvidia card back down when I was trying ' primusrun vboxmanage startvm "Windows XP" ' and virtualbox --startvm "Windows XP". That post mentions root is needed to make it work so I tried some tricks with symbolic links that for whatever reason didn't work. So I imported the vbox disk... sudo virtualbox. I added root to the bumblebee, video, audio group, etc. - probably some things not needed but for experiment's sake to cover all bases. This is what I found:

Optirun works, however. (It's funny, I posted a while back that I couldn't get optirun to work with Windozey things).

I'm not sure how to diagnose the segfault so I just thought I'd offer the findings here.

X Error when application quits

This error shows up for some, but not all applications, and I can't make it reproducible: When the application quits, this (or a similar) error is shown on the console:

X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
Major opcode of failed request: 137 (DRI2)
Minor opcode of failed request: 7 (DRI2GetBuffersWithFormat )
Resource id in failed request: 0x540005d
Serial number of failed request: 3300
Current serial number in output stream: 3300

This does not happen when I use optirun instead of primusrun.

Problem running primusrun

I'm finally (at last) trying primusrun, but after managing for building it, I'm currently facing this error:

./primusrun glxspheres
Polygons in scene: 62464
Visual ID of window: 0x21
Xlib:  extension "NV-GLX" missing on display ":0".
X Error of failed request:  BadAlloc (insufficient resources for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Serial number of failed request:  25
  Current serial number in output stream:  26

Anything I've missed or explanation for that ?

crash with oil-rush

Today I tried oil-rush with primus, but I am getting this error, while the game is loading (a black window appears, but not more):

X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
Major opcode of failed request: 151 (DRI2)
Minor opcode of failed request: 8 (DRI2SwapBuffers )
Resource id in failed request: 0x4600002
Serial number of failed request: 29
Current serial number in output stream: 30

I tried, but I failed

I like the idea of this, but maybe I am to silly to try it out (keep in mind, that I have a working bumblebee configuration here):

do you need more information?

Support for VDPAU?

I'm finding that Primus is too similar to VirtualGL.

That is, they share the same flaw. The transport method only recognizes GLX calls.

VDPAU will not work unless the app window that requires it is rendered on the Nvidia X server before being displayed on the Intel X server.

The solution is buffer sharing such as dma_buf, but this is currently not possible with the proprietary driver.

What does exist are CPU-bound solutions such as hybrid-windump provide a crude way to achieve VDPAU, but the windowing is really awful.

Would it be possible to process calls for libvdpau using a similar method?

Warcraft III Frozen Throne crashes when changing resolution

When changing the resolution of Warcraft III Frozen Throne (using wine 1.5.13) in primusrun, the game crashes. The console shows:

X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 11 (X_GLXSwapBuffers)
Serial number of failed request: 1037
Current serial number in output stream: 1038

With optirun, changing the resolution is working fine.
