Hardware mipmap generation broken on ATI Linux drivers.

Post by cdleonard »

I recently upgraded ATI Linux drivers and now textures look corrupted. All Ogre demos are affected but not other apps (I tested native Doom3 and some windows games through wine). I'm reasonably confident this is due to hardware mipmap generation. The following modification in ExampleApplication.h will work around the issue:

Code: Select all

             // If returned true, user clicked OK so initialise
             // Here we choose to let the system create a default rendering window by passing 'true'
-            mWindow = mRoot->initialise(true);
+            //mWindow = mRoot->initialise(true);
+            mRoot->initialise(false);
+
+            mWindow = mRoot->createRenderWindow("Dummy", 1024, 768, false);
+            Ogre::RenderSystemCapabilities *caps = mRoot->getRenderSystem()->createRenderSystemCapabilities();
+            caps->unsetCapability (Ogre::RSC_AUTOMIPMAP);
+            mRoot->getRenderSystem ()->useCustomRenderSystemCapabilities(caps);
+
+            mRoot->getRenderSystem ()->destroyRenderWindow(mWindow->getName());
+            mRoot->getRenderSystem ()->reinitialise();
+
+            mWindow = mRoot->createRenderWindow("Real", 1024, 768, false);
             return true;
This is obviously not a real solution; it just hacks render system capabilities to avoid hardware mipmaps.

Here is Ogre.log running the TextureFX demo. Ogre version is latest branches/v1-6 svn.

Maybe there's a bug in the way Ogre uses hardware mipmap generation? This has happened before on a certain version of Nvidia drivers.

Re: Hardware mipmap generation broken on ATI Linux drivers.

Post by sinbad »

Yes, this has happened before on NVIDIA and it was confirmed as a driver bug and fixed in the next revision. It actually seems that not that many people use the hardware mipmap generation option in GL (or maybe it's just games are either not supporting GL or using pregenerated mipmaps). Doom 3 is pretty ancient tech these days and I'm kinda sick of driver writers assuming that we only use what old iD engines use.

I'll see if I can confirm this on my ATI / Linux test box next time I'm on it, report it to ATI and work around it.

Re: Hardware mipmap generation broken on ATI Linux drivers.

Post by sinbad »

Haven't had time to test this yet. However, try this: in OgreGLRenderSystem.cpp, find this code:

Code: Select all

        // Check for hardware mipmapping support.
        if(GLEW_VERSION_1_4 || GLEW_SGIS_generate_mipmap)
        {
			bool disableAutoMip = false;
#if OGRE_PLATFORM == OGRE_PLATFORM_APPLE
			// Apple ATI drivers have faults in hardware mipmap generation
			if (rsc->getVendor() == GPU_ATI)
				disableAutoMip = true;
#endif
			if (!disableAutoMip)
				rsc->setCapability(RSC_AUTOMIPMAP);
        }
and change it to this:

Code: Select all

        // Check for hardware mipmapping support.
        if(GLEW_VERSION_1_4 || GLEW_SGIS_generate_mipmap)
        {
			bool disableAutoMip = false;
#if OGRE_PLATFORM == OGRE_PLATFORM_APPLE || OGRE_PLATFORM == OGRE_PLATFORM_LINUX
			// Apple ATI drivers have faults in hardware mipmap generation
			if (rsc->getVendor() == GPU_ATI)
				disableAutoMip = true;
#endif
			if (!disableAutoMip)
				rsc->setCapability(RSC_AUTOMIPMAP);
        }
I suspect it may fix your problems. Maybe ATI's entire latest driver stream has broken support for GLEW_SGIS_generate_mipmap.

I didn't try your fix but I'm sure it would have worked. It's a pretty brutal fix; I don't think it should get into svn. The proper way to do this is some sort of blacklist of driver capabilities.

Anyway; I recently upgraded my drivers and the issue is gone.

Anyway; I recently upgraded my drivers and the issue is gone.
Yay!

Yes, I'd really like to blacklist drivers, but GL is a PITA in that it doesn't provide any way to retrieve the full driver version, just the GL version which doesn't always reflect all the incremental changes. AFAIK you have to directly query the GL driver libraries to get this information, which is really nasty.

This particular bug can be localized to a GL version (2.1.8304.0). The fixed version reports 2.1.8494.

It would be awesome to have a capability blacklist inside a text file you can trivially update and play with. Recompiling ogre should be avoided.

But it's even better if drivers "just work". Let them test with Ogre before releasing new versions. :twisted:

My solution would be to try to educate the users enough so that they would undestand not to complain to me if their graphics card is having problems.

I don't see how more than that could be done cost-effectively.

In fact I don't think that would work... It is very hard to know which problem originates from the graphics card and which from the application.

The blacklist is like anti-virus software virus blacklists: it absolutely needs to be very regularly updated or it is near-useless.

How about a whitelist? :)

I've recently discovered that hardware mipmap generation is still broken when a large amount of textures are involved. It does not result in corrupt textures but rather random crashes inside the driver; probably from some form of memory corruption. It can be reproduced using ember; but it's difficult because there are other unrelated bugs in there as well.

Anyway; my suggestion is to apply sinbad's patch to trunk and 1.6 and forget about hardware mipmap generation on ati/linux. This is such a silly feature; causing far more trouble than it's worth.

Just to be sure, you mean this code right?:

Code: Select all

        // Check for hardware mipmapping support.
        if(GLEW_VERSION_1_4 || GLEW_SGIS_generate_mipmap)
        {
         bool disableAutoMip = false;
#if OGRE_PLATFORM == OGRE_PLATFORM_APPLE || OGRE_PLATFORM == OGRE_PLATFORM_LINUX
         // Apple ATI drivers have faults in hardware mipmap generation
         if (rsc->getVendor() == GPU_ATI)
            disableAutoMip = true;
#endif
         if (!disableAutoMip)
            rsc->setCapability(RSC_AUTOMIPMAP);
        }
I just wanted to be sure because I have to apply it to my slightly custom version of Ogre. I am trying to fix the bug brought up in this thread.

Yes, specifically it's rev 8656 in Subversion.

I don't know the state of this, but I had the same problem with a Debian 32bit running in an AMD64. I've installed a Debian 64bit and I don't need to patch the Ogre code. All works perfectly.

Thanks (Sorry for my mistakes, I'm Spanish)
