Getting Intel's GEM?

valis · n00b Joined: 20 Feb 2007 Posts: 19

Still getting only 60 fps (no compalints about missing gem).
Running libdrm master, dri2proto master, kernel drm-intel-next (thanks), mesa master, and xf86-video-intel dri2.
Possible I missed something else?

glxinfo says:
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) 965GM GEM 20080716
OpenGL version string: 2.1 Mesa 7.3-devel

Thanks again.

Mesa now defaults to sync to vblank. The 60fps mean's that glxgears are updated with rates based on monitor HZ.
If you wanna earlier behavior, add something like this in your home folder in .driconf file:

Thanks, now I'm getting around 750fps

1000+ fps,

Attempting to test out dri2 now, any of you folks have it up?
Do I need to be running drm-gem mesa? Xorg-server-1.5.1 seems to want dri_sarea.h which I don't see in mesa master.
Maybe I should be running xorg-server-9999?

Thanks.

Yep, you will need xorg-server-9999. I've tried it this morning but I got some problems with libxcb, well, actually with libX11. The thing is that xorg-server-9999 expects some symbols to be defined in libX11 but they are not in my libX11-9999. It seems related to the new XCB socket handoff mechanism for Xlib/XCB.

I've tried with the handoff branch in libxcb but no luck

libxcb fails on compile since some of the patches in x11/x11-libs/libxcb/files are no longer valid in the current libxcb scm

I'got some of them removed and it did compile and it built libX11 but xorg-server didn't find some symbols. I guess there's a branch in xorg-server for the new XCB socket handoff mechanism.

Bizarre, I just removed the patches from the libX11 and libxcb ebuilds, added --enable-dri2 to the xorg-server-9999 ebuild and everything worked yesterday.

EDIT: I did need to update dri2proto.

For those with working DRI2, does redirected direct rendering work yet? What about tearing?

guys since some of you already figure out how to enable dri2, could someone post a guide of how to DRI2, or could someone give me a light on how to do it plz, cause some ppl say that we need the module in the kernel, other ppl say we dont, and is just to add the x11 overlay and unmask some packages, do i need to unmerge my xf86-video-i810, wich one do i need to enable dri2 ?, and also, someone said "i got gem working, is very stable ......." what that means ?? the direct rendering working, or is gem indirect rendering to the frame buffer ??? plz someone give me light, im so confused

im using xf86-video-i810-2.4.2-r2
xorg-server-1.5.2
xorg-x11 7.4
media-libs/mesa-7.2
x11-apps/mesa-progs-7.1
x11-proto/xf86driproto-2.0.4

i have x11-proto/dri2proto-1.1 installed
but i really dont have idea how to make dri2 to work or even GEM

could someone explain plz

thx

Enabling UXA makes X unuseable and freeze, doesn't work at all with tiling enabled.
Here's a bit of info on the state http://thread.gmane.org/gmane.comp.freedesktop.xorg/32819

@joaquingt
The ebuilds I mention come from the x11 overlay.
You need to be running just about everything out of git. Also you'll need to make a local overlay, copy the libxcb and libX11 over and remove the patches, you'll get compile errors otherwise.
EDIT: forgot to mention you need to add --enable-dri2 to the xorg-server ebuild.
In your local overlay copy the xf86-video-i810 ebuild, at the top above "inherit x-modular git" add "EGIT_BRANCH='dri2'".
Go grab Anholt's kernel, see http://anholt.livejournal.com/39544.html and install it.

Now in xorg.conf add Load "dri2", under your graphics card device section add "Option 'DRI2' 'true'".
Once that works add to your device section "Option 'AccelMethod' 'UXA'" and "Option 'Tiling' 'no'" if you want dri2, this is very buggy on my laptop and tends to freeze in a short period.

> xf86-video-i810-9999 already had inherit x-modular git.
Sorry, I meant you should add EGIT_BRANCH="dri2" above that line to grab the dri2 branch. It may have been merged into master by now though.

> I'm running linux-2.6.27-git8, which has a bunch of stuff referencing GEM.
This is surprising to hear, hadn't thought anyone wanted that in the 27 kernel (maybe I don't understand the naming conventions).
You might try out 28 since it will be released with GEM so it will have all the newest stuff.
http://sourceforge.net/mailarchive/forum.php?thread_name=alpine.DEB.0.82.0810170031510.16504%40skynet.skynet.ie&forum_name=dri-devel

> libxcb did need the patch line removed from the ebuild.
You may already know this but, if you do want to try this stuff out you might checkout this patchset http://lists.freedesktop.org/archives/xorg/2008-October/039337.html

Glad to hear dri2 worked with UXA (even a bit, mine just froze immediately).
Were you able to kill (ctrl+alt+backspace) X? My terminal would be all screwed up (assuming gfx hardware was left inconsistent) and I could only get to it by kill -9.

xf86-video-intel-2.5.0 has been released, although it requires libdrm-2.4.0. This driver contains UXA, but does not contain the video tearing fixes. It also contains KMS, but that's apparently not expected to enter the vanilla kernel until 2.6.29.

So, anyone has a overlay for the missing bits of GEM and/of KMS for the rest of us?

I may install Gentoo just to try out GEM on my T61...
