Intel 945GM, Xorg, Kernel - performance

Zariel · 2009-04-14 12:39:23

glxgears performance drops a lot when using DRI2

vinvin · 2009-04-14 16:23:32

Anybody knows what this error means?
[drm:i915_gem_detect_bit_6_swizzle] *ERROR* Couldn't read from MCHBAR. Disabling tiling.

Maybe it is related to the big performance loss?

By the ways, enabling KMS in [non-testing] makes returns from suspend to ram display a black screen.

My does also but everything I have done so far has ran really smooth much smoother then without kms enabled.

I am getting about 18 - 22 average fps in etracer.

I am happy so far

This commit might make KMS more usable for those with GMA945:
http://cgit.freedesktop.org/xorg/driver … 651ce6afe2

I will try to rebuild the stack from git on the weekend.

Edit: FYI, this commit to the drm-intel branch of the kernel is supposed to speed things up for us quite a bit, too: http://git.kernel.org/?p=linux/kernel/g … cbb5de859c

anything on the memory leak? which seems quite more urgent than performance just asking...

You fellows are extremely happy: you've been worrying about performance. Look at where I got stuck: here

The memory leak has been marked as fixed ( http://bugs.freedesktop.org/show_bug.cgi?id=20704 ). It was a xorg bug which seems to be solved on 1.6.1 (just updated on [extra]).

ohh thanks, i just booted into KMS after updating xorg to see if it was fixed....now i see xorg sits tight at 50ish megs

now the last bug that annoys me....the transparency bug

Anyone already tried the new intel-2.7.0 release?

just built it.... had a couple of xorg restarts out of the blue while loading, yet now everything works fine.........feels faster. transparency bug still there though (KMS + UXA)

EDIT:

Mythtv freezes everything when run on fullscreen.

some font glitches are gone

performance on par with previous version (2.6.99something)

Running the RC3 here, no KMS nought. Maybe this weekend I'll find time to give it a try. Anyway, performance is acceptable with this release (still *not* good)

dcrabs · 2009-04-16 10:45:17

xorg-server-1.6.1 really fixed the memory leak. Finally KDE4 is enjoyable again. The memory of X is still increasing over time but very slowly. I will keep it running for a couple of hours and see if anything happens.

jacob_ · 2009-04-16 10:54:51

I'm running 2.7.0 right now. I needed to disable tiling to avoid corruption.

I've just come from 2.6.3 and performance may have improved a bit. I was having issues with youtube (X -> 100% CPU), and that may have improved a bit - not really sure yet, or how related that is to xorg-server.

eldragon · 2009-04-16 13:28:33

well, random lockups with 2.7 and KMS

im back to EXA, which boosts performance....feels nice.

karabaja4 · 2009-04-16 21:12:09

Well xf86-video-intel 2.7.0 didn't improve any 3D performance on my i915. UXA with KMS works, but 3D is awful - 1-2fps at etracer. xf86-video-intel-legacy is a bit better (at least menus work smoothly) but game still unplayable.

and game was playable before on about 30fps in some combination of xorg-server and drivers (don't remember which).

Same thing here. Disabled tiling otherwise screen contained garbage. (on a GM965 )
On a positive note, don't see any video tearing anymore!!

I tried it today, installing the xf86-video-intel-2.7.0 package from testing and activating KMS (the 'late' activation). No problems playing videos, but the menus are slightly garbled and the performance is worser than that obtained with xf86-video-intel-legacy.
the output of lspci|grep VGA is

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Here are some benchmarks:
xf86-video-intel-2.7.0 + KMS
glxgears ~320 FPS, gtkperf -a ~26 seconds, assaultcube 8-9 FPS, torcs 7-8 FPS, tremulous ~8 FPS.
xf86-video-intel-legacy-2.3.2 (no console framebuffer, i.e. no vga= option in grub menu)
glxgears ~780 FPS, gtkperf -a ~13 seconds, assaultcube ~45 FPS, torcs 7-8 FPS, tremulous garbled, unplayable.
Notes: assaultcube is custom compiled, torcs and tremulous come from the community repos. Torcs window lacks the decoration with intel-legacy, tremulous show garbled characters and mouse pointer, I'm even unable to start a game.
So I'll stick with the intel-legacy driver for now, but I'll try the new intel driver in testing when it'll be updated.

EDIT: I forgot to mention that tried xf86-video-intel-2.7.0 + KMS with and without the nopat option in grub, I didn't notice any difference.

ive got the exact same chip, my 3d performance is slightly better on glxgears (900fps), cube (i asume assaultcube = cube) 50fps, rest i wouldnt know
chromium at about 50fps, etracer at about 20fps, urban terror (800x600, about 2Xfps)
compiz works better too (slightly)

jacob_ · 2009-04-17 07:15:41

I'm getting some random freezes for the first time since 2.5.x, but the kernel modesetting is working great on dual monitor (GM45).

The other issue (that's yesterdays log):
$ zcat messages.1.gz | grep -c "freeing invalid memtype"
117672

I assume this is what I'm waiting for:

I would like to try it too, but i can't find it in testing. pacman -Sl testing doesn't displays any X related package.
How did you guys get this driver working in arch?
Thanks

Wait for your mirror to sync, but at the moment there is only a x86_64 version.

Ah yes ok sorry. Now I know where to look at least. I'm with i686. Thanks

Do you use XAA acceleration or the default EXA, like I do?

im using EXA, but UXA+KMS drops similar results (except for glxgears which drops to 400fps, who cares...) my device section here:

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"
    Option         "AccelMethod"    "EXA"
        Option      "MigrationHeuristic" "greedy"
    Option      "DRI"                    "True"
EndSection

im not sure if the DRI option is needed. and im not using kms+uxa cause of the random lockups and transparency bug.

gborzi · 2009-04-17 14:12:09

I don't think DRI is really needed, I tried using the "bare" ubuntu xorg.conf and got similar results.

Section "Device"
      Identifier      "Configured Video Device"
      Driver      "intel"
EndSection

Take a look at /var/log/Xorg.0.log to see which option is really used.

Arch Linux
