Here you are http://pastebin.com/F6aqj0H0

Your picture looks like streaming vertices don't work. As we support the new extension AMD_pinned_memory, I think the best way to debug is to disable it, but in this way, we would loose the biggest performance gain.
So could you please try it again with this patch:
http://markus.members.selfnet.de/dolphin/use_buffersubdata.patch

The patch fixed it, thanks.

I have a similar problem with last compiled Dolphin (3.5-1034)
No artefact, just a blackscreen for Wii and GC games/homebrews/systemenu/bios.
I have try your patch, it change nothing.

Linux Ubuntu 12.10 x86-64 / AMD Radeon HD 7850 / Catalyst 13.2 bêta 7 / Core I5 3570K / 16Go ram

Yo degasus, fyi that patch didn't fix my issue.

The official catalyst release works fine here. I have problems installing the beta though.

seele:
I think we should split this issue as amotiss report a different bug. It seems that some fglrx versions/gpus/distributions don't like the pinned memory extension. So now it is disabled complete for fglrx.
Do you want to check the performance difference between master 3.5-1035 and the last patch?

others:
Can someone please try it on a debug build? Perhaps some gl_errors would help to point out the issue.

I'm sorry for this issue isn't fixed as fast as the others, but it's hard to debug just "black screens" :-(

Do not be sorry, the work of the whole team is awesome, you do good work, thank you for all that has been done ! Be blocked it can happen :)

I compile the new revision and test all your need, be patient ! :)

Okay, i tested the new build (1035), same problem, blackscreen.

I try with two games, Resident Evil rebirth PAL, and Resident Evil Code Veronica X Pal.

Logfiles with debug dolphin => http://paste.ubuntu.com/5621879/

Reccompiled to ver 3.5-1044 and the problem returned. Once again though, the patch you provided fixed it.

seele: but to be sure, "pinned memory" is now listed on "missing extensions"?

How do I check? The OSD does show a "Missing Extensions:" but there's nothing following the colon.

Confirmed, i have no graphics with fglrx. All is black.
But http://markus.members.selfnet.de/dolphin/use_buffersubdata.patch fixed the problem for me.

nerzhultheking: which gpu / driver / os do you use?

so, finally I gave up to find which versions of fglrx are broken and disabled it for all non-windows plattforms.

seele, nerzhultheking: it should now work for you
amotiss: I think we have another issue. But as there are no gl errors, I still don't know what has happend :-(

amotiss: You've wrote you use a beta gpu driver. Maybe it's because of the driver. Is it possible to try some different versions?

I have GTX660 with 310.40 driver and this bug happens to me.
Appears message: "Missing Extensions: PinnedMemory".
Patch didn't help, this error message still appears and no video.

YuriShish: this bug seems to be amd only, so I think you have another issue. What are you MSAA settings? Could you please try a debug build (eg http://dl.dolphin-emu.org/builds/dolphin-GLSL-master-3.5-1023-dbg-x64.7z ) and look for ogl errors

seele, nerzhultheking: Can you please check current master? Sonic has pushed a patch disabling pinned memory on index buffer which solve this issue for him.

amotiss: I'm sure it wouldn't help you as disabling it completely doesn't help either :-(

in Fedora 18 x86_64 NVidia 9800GT (nouveau mesa 9.1) dolphin emu 3.5-1062

I'm getting black screen/video, sound is working fine.

Hi,

Under Debian, with a Geforce GT 30M and the latest NVIDIA drivers, I also get the message "Missing Extensions: PinnedMemory", and the ingame speed is 1/2 of the speed I had before the GLSL merge.

How can I compile a Debug build under Debian with cmake?

Thanks.

cmake -DCMAKE_BUILD_TYPE=Debug

fast.rizwaan: can you please upload the output of glxinfo? I doubt nouveau supports glsl130

ccox421: efb2ram is known to be slower, else glsl /should/ be faster.

Thanks.
Recompiled the Debug version, but I do not see anything related to OGL in the output. What should I expect, or should I do anything to test it?

wickmarkus: I don't understand well, is it a general remark, or is there something I should change in the config?

ccox: Tt is more like a general remark. Or just be sure efb2tex is selected (default in most games). Have you tried the "hacked buffer" option? This may speed up, but not up tp 50% ...

OK. I have efb2tex selected, and indeed the "hacked buffer" option improves the framerate, but still it is slower than before...

The game you're playing might have EFB to RAM forced in its config. Changing the graphics settings in-game overrides this (but the settings are forced in the config for good reason, so don't report bugs after doing this).

I can confirm that after the GLSL merge I get nearly half of the speed with the OpenGL plugin (copy to RAM or Texture doesn't matter).
My system: Amd Hd4850 (Catalyst 13.1), Intel e8400, WindowsXP, Dolphin r3.5-1103 32-bit

I checked, and the games I tested have efb2tex enabled... So the half speed is probably related to the PinnedMemory problem. BTW, I have a GeForce GT 330M.

FYI, I tested a many versions, and this problem was not present before the GLSL merge (Rev. d63d7fde9e9c was fine and fast), and the problem appeared in the first compilable version (Rev. 234604e067c4).

I use a 64-bit Dolphin version under Linux Debian (unstable) with latest Nvidia beta drivers.

neobrain: your issue should be fixed by this commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=cb12bf7606116e473bf19aee84582b4cee7f895d

btw: Rendering on nouveau is also broken with UBO. There is another offset issue (like the one on radeon) and textureing isn't working at all.

Seems more or less the same issue which happens on Gentoo x86_64 AMD 4850HD but I have less weird vertices and more solid color screens

Mesa building info:

media-libs/mesa-9.1.1 was built with the following:
USE="bindist classic egl gallium gles2 llvm nptl shared-glapi -debug -gbm -gles1 -openvg -osmesa -pax_kernel -pic (-r600-llvm-compiler) (-selinux) -vdpau -wayland -xa -xorg -xvmc" PYTHON_SINGLE_TARGET="python2_7 -python2_6" PYTHON_TARGETS="python2_7 -python2_6" VIDEO_CARDS="radeon -i915 -i965 -intel -nouveau -r100 -r200 -r300 -r600 -radeonsi -vmware"

When I have time, I will try recompile Mesa with that patch

I confirm that the issue is fixed with the mesa patch but it isn't in Mesa 9.1.2

I tested using the patch with a custom ebuild and it worked

airlied just promised me it will be in 9.1.3. They missed this commit on the last cherry-pick

didn't work for me on Mesa 9.1.3, patch didn't help, I'm using nouveau (Gallium 0.4 on NVCE)

thepo, nouveau's currently unusable for Dolphin, and the patch was for AMD cards anyway. Use the official Nvidia drivers.

@pauldacheez not going to happen, No KMS, some of my programs segfault when trying to start them while running perfectly fine in Nouveau, and it's a binary blob.

can't you just include an option to toggle the use of the extension or to toggle between OGL2 and OGL3.

thepouar: The broken feature are uniform buffer objects (ubo). You can disable it here, but there will be a huge performance drop:
https://code.google.com/p/dolphin-emu/source/browse/Source/Plugins/Plugin_VideoOGL/Src/Render.cpp#361

Or try to help the neauvou project to fix this issue :-)

This bug is finally also fixed on nouveau: http://cgit.freedesktop.org/mesa/mesa/commit/?id=5c37039797938e43a7dfb6c7d39a1f0bb4f32df3

As this patch is also in mesa-9.1.6, all mesa drivers should be able to run dolphin out of the box soon. Also the performance seems to be fine on mesa-9.2 :-)

I'll create a workaround to disable UBO on unsopported drivers.

Could someone please test again the fglrx pinned memory + index buffer bug?

I have no idea about how to test the bug, I am newcomer, test the emu during the two week, and the speed of linux version is slower than windows one.

I am glad to test it and speed up it.

I have AMD FireGL M8900 (i.e. 6970M) + fglrx driver: 13.4 + Smash Bros Brawl.

What configurations needed to test the bug?
Need patch file?
Only show black window?
Which version?

Can you try to change this line:
https://code.google.com/p/dolphin-emu/source/browse/Source/Plugins/Plugin_VideoOGL/Src/VertexManager.cpp#64
from
s_indexBuffer = new StreamBuffer(GL_ELEMENT_ARRAY_BUFFER, MAX_IBUFFER_SIZE, (StreamType)(DETECT_MASK & ~PINNED_MEMORY));
to
s_indexBuffer = new StreamBuffer(GL_ELEMENT_ARRAY_BUFFER, MAX_IBUFFER_SIZE);

Then you either see a black screen or not.

For performance, have you also tried the OpenGL backend on windows? As DirectX isn't available on linux, only the performance of the OpenGL backend matters. It's also known that the amd linux driver is a bit slower than the windows one.

I got a black screen w/ dolphin 3.5-1686 + AMD_pinned_memory.

I clean & rebuild 3.5-1687, remove ~/.dolphin-emu & installed dirs & files, and get screen other than black.

I upload 5 screenshots.

Does this issue occur again with revision 672fa65ee76c or has it been fixed in recent driver versions?
