https://bugs.freedesktop.org/show_bug.cgi?id=39588 --- Comment #10 from huihui.zh...@intel.com 2011-08-10 19:20:07 PDT --- (In reply to comment #8) (In reply to comment #7) (In reply to comment #6) Created an attachment (id=49902) View: https://bugs.freedesktop.org/attachment.cgi?id=49902 Review: https://bugs.freedesktop.org/review?bug=39588attachment=49902 [details] intel: Set ctx's drawbuffer according to drawables visual This patch doesn't seem like the right fix, and the commit message is a bit confusing to me (see below). What particularly concerns me is that the change that created the bug was in common code, but the fix is in driver code. Does this leave other drivers broken? egl_dri2 creates contexts with a doubleBufferConfig when PIXMAP and WINDOW bit is request, so _mesa_init_color sets DrawBuffer[0] to GL_BACK. I'm confused about this. The application creates a context with a particular fbconfig, and that determines whether the context is single-buffered or double-buffered. What does egl_dri2 have to do with anything? If a pixmap surface is created egl_dri2 will use a single buffer config, so MakeCurrent has to adjust DrawBuffer[0] to the current drawable. One other nit with the commit message. The usual way to reference a bug is: Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=39588 This makes it easier to search in 'git log' for things to cherry pick to stable branches. I just try your patch. ./xeglgears -pixmap works fine Do the other modes mentioned in comment #0 also work? but ./xeglgears -pixmap -fullscreen doesn't work The pixmap fullscreen mode doesn't work out on both the 7.9 and 7.11. If fullscreen didn't work with Mesa 7.9, it's not the same bug. Would you mind helping me looking into this issue. Thanks a lot. Sorry for the late response.

https://bugs.freedesktop.org/show_bug.cgi?id=39588 --- Comment #5 from Benjamin Franzke benjaminfran...@googlemail.com 2011-08-04 02:42:36 PDT --- (In reply to comment #4) I've bisected this to: commit 87dde5b1cd596c4008695ff2db9469f88c09f925 Author: Benjamin Franzke benjaminfran...@googlemail.com Date: Wed Feb 9 15:30:20 2011 +0100 egl_dri2: Use double buffering for window surfaces We really should have piglit tests for drawing to pixmaps and pbuffers. Simple tests that just draw a single triangle should be sufficient. Ok, Thanks for bisecting. At the time of writing this patch I owned only radeon hardware, where it works (r600g). So a piglit test wouldnt have helped directly (sure, you'd have found it earlier). The commit was about using dri double buffer configs for window surfaces (made the wayland backend code nicer). This results in contexts being created with double buffer configs, which are somewhat mixed with single buffer configs, when using pixmap surfaces. Why does this work with r600g? st/mesa sets the context's DrawBuffer[0] depending on its visual render_buffer, which is set by st/dri depending on the drawables gl_config's doubleBufferMode. I'll attach a patch that does this for intel in make_current. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
