Bad performace for NV18 driver

Bad performace for NV18 driver

[Carlos Garces]

Hi!

I have some strange results on my test with nouveau drivers

I'm using a old GeForce4 MX 4000 (NV18) with 128 MB.

I have made 2 test.

-The default configuration, using nomodeset without nouveau_vieux_dri.so

$inxi -G
Graphics:  Card: NVIDIA NV18 [GeForce4 MX 4000]
           X.Org: 1.12.4 drivers: vesa,nouveau (unloaded: fbdev)
Resolution: 1024x768@0.0hz
           GLX Renderer: N/A GLX Version: N/A

-The "optimized" configuration, after removing nomodeset, installing
the 3d driver (nouveau_vieux_dri.so, package libgl1-mesa-dri) and
configure the xorg to use only nouveau

$inxi -G
Graphics:  Card: NVIDIA NV18 [GeForce4 MX 4000] X.Org: 1.12.4 driver:
nouveau Resolution: 800x600-XyBiMD9AD2I@public.gmane.org
           GLX Renderer: Mesa DRI nv18 x86/MMX+/3DNow!+/SSE GLX
Version: 1.2 Mesa 8.0.5

The resolution is 800x600 because was impossible for me set up  1024x768

There is the full xorg log
http://pastebin.com/2ZbMwyRK

The results are strange for me. I expect better performance on
"optimized" configuration but some test using Cairo are very bad (0,54
vs  5,38).

The test are available at
http://openbenchmarking.org/result/1306076-UT-2DGPUTEST63

Any idea to improve the performace of NV18?
Any know issue with nouveau_vieux_dri.so and NV18?

It's a little difficult to tell anything without seeing your xorg.conf
-- it seems like 1024x768 should work fine. You also appear to be in
16-bit mode, and using fairly old software (xorg 1.12, mesa 8.0,
xf86-video-nouveau 1.0.1). What kernel version are you on? Although
it's a fairly old card so perhaps there hasn't been much improvement
on it. In recent X versions, things get auto-detected for the most
part and you can forgo most explicit configuration like
modelines/etc... not sure if that's the case for xorg 1.12 or not.

After update the system now I use:

Kernel 3.9.2
x server 1.12.4
nouveau 1.0.7

the xorg config are at:

http://pastebin.com/2LUxLiVs

It's the one installed by my distro, without any modification

I have made 2 test.

Normal boot
Xorg at http://pastebin.com/reZdAXEF
GLX Renderer is detected as GLX "Mesa DRI nv18 x86/MMX+/3DNow!+/SSE GLX"


Same configuration with nomodeset
Xorg log at http://pastebin.com/ZbXBG8sz
GLX Renderer: Gallium 0.4 on softpipe

Results for Cairo test with and without nomodeset
http://openbenchmarking.org/result/1306082-CGAR-CAIROTE23

Full results from Friday (before update Mesa)
http://openbenchmarking.org/result/1306072-UT-2DGPUTEST95


The result with Cairo are better in the updated system, 0.63 FPS vs
0.54 FPS but still worse than boot with nomodeset (7,84 FPS)

Any ideas to improve the results with Cairo?

Good call

Bad call, your resolution issues are due to messed up config

If you really insist on having such an "interesting" setup, start from
scratch and build on top of it - one section at a time. I would
recommend getting the "minimal" xorg.conf [1] as a base

Note that nouveau correctly detects that the monitor is 1024x768 60Hz
capable.

"(II) NOUVEAU(0): Modeline "1024x768"x60.0"

Something is the config you're feeding it causes the issue

If you do a bit of search[2] you'll notice that in quite a few cases
cairo/sw is quite fast

Quite a few of the benchmarks in your original post were faster using
nouveau

On that note, I believe that a question in terms of "Program XXX is
rendering very slow, is there any way to improve that ?" would be more
beneficial
