Re: about video memory detection in wine
I'm sure what will happen to the GL_ATI_meminfo but perhaps it makes sense to unify it with WGL_AMD_gpu_association ? Roderick

RE: about video memory detection in wine
Hi Here I just want to tell you that if a user uses an old driver that we don't support querying total memory will lead to vidmem = 0, that is unexpected, so we should have a check. It doesn't matter that the total memory is not documented, as long as it can tell you the true value. And for the old card that doesn't support ATI_meminfo can still go the fall back path. I think the biggest benefit from using this extension is that you don't have to update the vidmem list for newly realeased ATI cards, and you can get the correct amount of video memory for the same render string but with different video memory (eg: HD4870 may have 1GB memory or only 512MB memory) Regards Sunny -Original Message- From: Stefan Dösinger [mailto:stefandoesin...@gmx.at] Sent: Saturday, August 15, 2009 12:31 AM To: Sun, Sunny Cc: Roderick Colenbrander; wine-devel@winehq.org Subject: Re: about video memory detection in wine Am Friday 14 August 2009 18:01:07 schrieb Sun, Sunny: +if(gl_info-vidmem 64 * 1024 * 1024) +gl_info-vidmem = 64 * 1024 * 1024; I guess the idea is that no ATI card that was ever supported on fglrx has less than 64 mb of memory?

The concern is that lack of spec documentation makes it harder to maintain the code. Like the GL_ATI_texture_compression_3dc code, which is essentially based on guessing. However, for ATI_meminfo we have your info in the mailing list archives, and if the extension is eventually updated its ok I guess. I'll send the patches on monday with a few minor improvements.

This seems like the wrong way to go. I'm wondering if there is another way to detect VRAM? There should be a way to determine VRAM from Xorg? Why should OpenGL or DirectDraw be the method that Wine uses to determine video RAM? Why should Wine have a fixed value based on a list? Maybe I'm being stupid, but I think it would make sense for the display server (xorg) to know how much VRAM a graphics card has...

Xorg explicitly doesn't tell programs how much memory they have as it can lead to bad designs and these days cards have a sufficient amount of memory for 2D. In case of 3D programs the amount of memory is more important to have. OpenGL itself (except using the ATI extension) does not provide a way to query the amount of video memory or the exact videocard (yes it exports the renderer string but d3d exports the pci id as well. Like X, OpenGL wants to hide this information from the designer. Though these days this information is becoming more and more important for designers as they can decide to e.g. use a different code path. Native Linux games like Quake Wars for this reason use vendor specific extensions like NV-CONTROL to obtain some info. It might make sense to have a cleaned up version of the ATI memory extension as real ARB extension. For modern games it is crucial. Hopefully AMD can clean it up. When I last checked this extension months ago the total amount of memory wasn't in the spec, it might make sense to update the spec. Regards, Roderick Colenbrander

The issue is that GL_TOTAL_PHYSICAL_MEMORY was added a bit after the other 4 query flags, Sunny says they're working on adding it to the spec. So there is a range of fglrx version that supports ATI_meminfo, but returns zero on GL_TOTAL_PHYSICAL_MEMORY_ATI. So if we want to use this as-is we have to take care that we don't set the vidmem to zero accidentally. Another extension is a possible way to go, but there are still r300 to r500 chips where the driver has been discontinued and where the vidmem info is useful too. These cards most likely won't get the new extension in that case. @AMD: The discontinuing of fglrx for r300-r500 chips is really a pain for us. There's essentially no way to use those cards on Linux right now. The Open Source driver that ships with current distros can't even run 3DMark 2000 properly, and the 9.3 driver doesn't run on up to date distros. Currently I have to tell everyone who has such a card that it probably won't be useable for probably another year :-(

RE: about video memory detection in wine
Hi
We have implemented GL_TOTAL_PHYSICAL_MEMORY for about 8 months, so you will
not get the GL_INVALID_ENUM error. I think it will be documented later.
I have tested with your patch with 3 ATI asics, all of them can get the correct
amount of video memory (1GB, 256MB, 128MB).
For the reason that GL_TOTAL_PHYSICAL_MEMORY is implemented after
GL_ATI_meminfo, so if a user uses too old driver (about before Catalyst 9.2),
he may have problems to get the correct amount of video memory, so I suggested
to add the following code in your patches:
+if(GL_SUPPORT(ATI_MEMINFO))
+{
+/* All GL_ATI_meminfo enums return 4 ints, even the (undocumented)
+ * GL_TOTAL_PHYSICAL_MEMORY_ATI one, which returns {mem, 0, 0, 0} */
+GLint mem[4] = {0};
+/* Returns the vidmem in KB */
+glGetIntegerv(GL_TOTAL_PHYSICAL_MEMORY_ATI, mem);
+TRACE(Video memory from OpenGL: %d MB\n, mem[0] / 1024);
+gl_info-vidmem = mem[0] * 1024; /* convert from KBs to bytes */
+if(gl_info-vidmem 64 * 1024 * 1024)
+gl_info-vidmem = 64 * 1024 * 1024;
+}
Please tell me if you have any questions, thanks and good night!

D3D8 and D3D9 only report the free amount as well, but DirectDraw can return the total amount. There are some games that first query the total amount using ddraw, then continue with d3d8 or 9. Depending on what other apps are doing, reporting the currently free amount as total might result in the app thinking that free vidmem total vidmem, running into all sorts of troubles. (For example, another app frees a lot of textures between the ddraw vidmem query and the d3d9 vidmem query) The other issue is that if some other apps use lots of video memory(like Compiz, etc), then we can still run into the same out of memory issue if other apps consume too much video memory. We should probably also fall back to a saner default on newer d3d10 class cards - a radeon 9500 isn't really representative for them any more.

(For example, another app frees a lot of textures between the ddraw vidmem query and the d3d9 vidmem query) It is even worse. Even OpenGL apps like WoW use ddraw for querying the amount of video memory at startup! In case of Nvidia the amount of video memory and the pci ids are advertised using the NV-CONTROL extension. At some point I plan on adding code for that. Even when using such extension the current fallback is still needed. The list needs some updates.

I still have to update that part but haven't had time for it yet. Roderick
about video memory detection in wine
Hi You are using the hardcoded method to get the vidmem now (in function IWineD3DImpl_FillGLCaps), first you call glGetString(GL_RENDERER) to get the GPU renderer string, and then you use this string to set the vidmem in your code. Unfortunately you don't get all of the ATI GPU's string now, for our workstation GPU, the string is always like ATI FireGL V8700, so you don't recognize this GPU and consider it as ATI_RADEON_9500, then 64MB is set which doesn't support 1280x1024 resolution (Out of adapter memory). I think you can first detect GL_ATI_meminfo in glGetString(GL_EXTENSIONS); if GL_ATI_meminfo exists, then you can use glGetIntegerv(GL_VBO_FREE_MEMORY_ATI, param) to get the current free video memory, you can see more info at: http://www.opengl.org/registry/specs/ATI/meminfo.txt if GL_ATI_meminfo doesn't exist, you can fall back to the original method. Please tell me if you have any questions. Regards, Sunny, Sun
RE: about video memory detection in wine
Hi I am sorry I forgot to introduce myself. I am a software engineer at AMD, working on OpenGL graphics driver, I am working with wine issues now. Some uses complained that there are too many issues to play games with wine with AMD graphics card, so we want to improve the quality. That's all, Thanks Regards Sunny From: Sun, Sunny Sent: Wednesday, August 12, 2009 4:04 PM To: 'wine-devel@winehq.org' Cc: Jin, Jian-Rong; Hu, Li; Guan, Xiao-Feng; Wang, Robin Subject: about video memory detection in wine Hi You are using the hardcoded method to get the vidmem now (in function IWineD3DImpl_FillGLCaps), first you call glGetString(GL_RENDERER) to get the GPU renderer string, and then you use this string to set the vidmem in your code.
