[Solved] [LINUX] ATI Radeon 2xxx and higher problems

[Lone_Wolf]

Archlinux now has upgraded mesa to 7.10.1 , and this means the driver for ati R600 cards ( HD 2xxxx and later) is changed from classic mesa to gallium3D.

according to The Direction Of ATI Radeon Graphics In Ubuntu 11.04 on phoronix, Ubunty 11.04 Natty will also use the gallium3d driver in mesa 7.10 r600 cards.

The current state of the gallium driver breaks oolite, it hangs on the logo screen and can only be killed.

By changing shader-mode in gnustep.defaults from 3 to 0 , oolite can start , but is very unstable.

I will continue to look into this, and also try out the mesa 7.11 development version.

[Lone_Wolf]

I have looked into this deeper (even compiled mesa myself), and have now found 2 solutions .

1. downgrade mesa to the highest version for your distro that still uses the r600 classic driver.
For ubuntu this will likely be the version supplied with 10.10

oolite also runs fine with mesa 7.10 as compiled for archlinux.

2.
start oolite from a terminal with this command :

Code: Select all

LIBGL_ALWAYS_INDIRECT=1 oolite

you will loose all shader functions, but oolite does run stable.

By changing shader-mode in gnustep.defaults from 3 to 0 , oolite can start , but is very unstable.

This is a long shot, but:

• Try setting it to 1 (SHADERS_OFF) instead of 0 (SHADERS_NOT_SUPPORTED).
• Try adding an entry to gpu-config.plist with maximum_shader_level = SHADERS_OFF;.

I do have an HD 2400 system to test on, but it doesn’t have a standalone Linux install. I’ll try to get around to fiddling with 11.04 alpha.

[Lone_Wolf]

changing shader-mode to 1 in .GNUstepDefaults makes oolite run fine .
with shader-mode 2 and 3 oolite hangs on the icon screen, taking full cpu of 1 core.

adding the section below to gpu-settings.plist makes oolite run stable without shaders regardless of shader-mode value in .GNUstepDefaults
Note : AMD RV770 is the chipset used in my videocard, a HD 4890 .

Code: Select all

	"ATI R600 family (X/Gallium3D)" =
	{
		match =
		{
			vendor = "X.Org";
			renderer = "Gallium .* on AMD RV770";
		};
		maximum_shader_level = "SHADERS_OFF";
		default_shader_level = "SHADERS_OFF";

	};

[JensAyton]

I’ve checked in a corresponding gpu-config fix for now.

[Lone_Wolf]

At first i thought the problems were due to the gallium 0.4 driver lacking features the classic driver did have, but a search for similar problems with other OpenGL applications was unsuccesfull.
I then compared the glxinfo output for both drivers, and found the gallium driver does support GLSL 1.2, and even has more OpenGL extensions then the classic driver.

so i did some more testing, using oolite 1.75.1 without any references to r600 gallium in gpu-settings.plist .
I tested with and without oxps, fullscreen and in window.
Once oolite had started, i choose NOT to load a commander, F2 > game options and tried to change the shader from none to simple.

In 1 case i got additional info in latest.log :

Code: Select all

  13:56:41.403 [rendering.opengl.shader.support]: Shaders are supported.
    13:56:41.445 [shader.compile.failure]: ***** ERROR: GLSL vertex shader compilation failed for dbshaderv.vertex:

  13:56:41.445 [shader.load.failed]: ***** ERROR: Could not build shader dbshaderv.vertex/dbshaderf.fragment.

Are there logcontrol.plist options i should enable to get more info ?

[JensAyton]

Are there logcontrol.plist options i should enable to get more info ?

No; the shader log you see there is what there is. (It’s provided by the GL driver, so we don’t have much control over it.)

However, in this case it’s pretty clear: dbshaderv.vertex is defining OO_TANGENT_ATTR, which it has no business doing – it’s defined by Oolite to indicate a certain feature exists, and shaders should at most be checking it, although they really shouldn’t do that either as it’s always true since test release 1.72 or some such.

The offending line will look something like:

Code: Select all

#define OO_TANGENT_ATTR 1

A problem like this shouldn’t be related to the crash, though; Oolite should just be falling back to the default shaders. (Missing features shouldn’t cause a crash either, of course. Oolite is supposed to be testing for all features it uses.)

[Lone_Wolf]

Code: Select all

#define OO_TANGENT_ATTR 1  // <---- Define OO_TANGENT_ATTR to 1 so that Oolite gives correct tangent data to shader.

found in werewolf.oxp , that explains why i didn't get it in tests without oxps.
I'll keep looking.

I think that's there in all of Killer Wolf's oxps... I safely delete that line and they run without any trouble. Looking at the oxp list earlier the only one of his you seem to have is werewolf.oxp, so that specific error message shouldn't pop up again.

[Lone_Wolf]

I had some spare time and looked into building the gallium driver myself again, with success .

By building mesa from git and installing the latest version of libdrm , oolite now works with full shaders and the gallium r600 driver.
It does look like the earlier problems were caused by the gallium driver, not by oolite.

i've run material test suite oxp 1.1 (had to remove the max version from requires.plist) and all but 4 tests were as threy should be .
In those 4 tests the circle / number was not present on all surfaces.

simple 13 , diffuse_map + specular_map
simple 14, specular_map only
full 13 , diffuse_map + specular_map
full 14, specular_map only

In a short trip from station to witchpoint and back , including a combat with 2 pirates i did not notice anything weird though.

In those tests, the numbers are only visible at certain lighting angles. Please check against the  reference renderings.

I take it we can remove the gpu-settings.plist entry, at least until 11.04 comes out?

[Lone_Wolf]

The tests views are indeed similar to the reference renderings.

For the gpu-settings.plist entry i see some possible solutions :

- include a version check of the driver like 'Mesa > 7.10.1'
shaders full True, disabled if False

- start oolite without shaders , but allow user to change to simple / full

If neither is possible removing the entry seems simplest.

I also made a oolite page in the archlinux wiki to describe these problems.

Edit :

when starting oollite from commandline i see this error :
EE r600_pipe.c:429 r600_get_param - r600: unknown param 45

(oolite 1.75.1 )

[Lone_Wolf]

when starting oollite from commandline i see this error :
EE r600_pipe.c:429 r600_get_param - r600: unknown param 45

from https://bugs.freedesktop.org/show_bug.cgi?id=35434
Looking at src/gallium/drivers/r600/r600_pipe.c though, it looks like
r600_get_param() is not handling PIPE_CAP_FRAGMENT_COLOR_CLAMP_CONTROL which
has been mapped to '45'

Unless oolite uses PIPE_CAP_FRAGMENT_COLOR_CLAMP_CONTROL, it looks like this error can be ignored.

As mesa has released 7.10.2 , i tested with that version but it has the same problems as 7.10.1 .

[Lone_Wolf]

I've tested with the 2 most recent stable mesa builds and oolite 1.76 now runs fine with full shaders in both.
Versions tested : 7.11.2 & 8.0.2

I think we can safely remove the gpu-config fix and even set full shaders as default for the R600 gallium driver.
