https://bugs.freedesktop.org/show_bug.cgi?id=99544 Bug ID: 99544 Summary: GL and VDPAU hangs on r600 (HD7650M) Product: Mesa Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: dbaryshkov@gmail.com QA Contact: dri-devel@lists.freedesktop.org Created attachment 129155 --> https://bugs.freedesktop.org/attachment.cgi?id=129155&action=edit GL application backtrace (Shenzhen I/O) I'm observing random GL and VDPAU hangs on my HD7650M card. The application will hang in graphics thread, but otherwise system stability is not impaired. Suck lockups happen both in windowed mode (e.g. google chrome) and in fullscreen mode (games). Lockups are more frequent when app is running with higher resolution. dmesg doesn't contain any messages from GPU. According to backtraces (see attachments) both GL and VDPAU hang in dri2 code (DRI2GetBuffersWithFormat and vl_dri2_screen_texture_from_drawable). uname -a Linux forlindon 4.9.0-1-amd64 #1 SMP Debian 4.9.2-2 (2017-01-12) x86_64 GNU/Linux $ dpkg -l | grep libgl1 ii libgl1-mesa-dev:amd64 13.0.3-1 amd64 free implementation of the OpenGL API -- GLX development files ii libgl1-mesa-dri:amd64 13.0.3-1 amd64 free implementation of the OpenGL API -- DRI modules ii libgl1-mesa-dri:i386 13.0.3-1 i386 free implementation of the OpenGL API -- DRI modules ii libgl1-mesa-dri-dbgsym:amd64 13.0.3-1 amd64 Debug symbols for libgl1-mesa-dri ii libgl1-mesa-dri-dbgsym:i386 13.0.3-1 i386 Debug symbols for libgl1-mesa-dri ii libgl1-mesa-glx:amd64 13.0.3-1 amd64 free implementation of the OpenGL API -- GLX runtime ii libgl1-mesa-glx:i386 13.0.3-1 i386 free implementation of the OpenGL API -- GLX runtime ii libgl1-mesa-glx-dbgsym:amd64 13.0.3-1 amd64 Debug symbols for libgl1-mesa-glx ii libgl1-mesa-glx-dbgsym:i386 13.0.3-1 i386 Debug symbols for libgl1-mesa-glx -- You are receiving this mail because: You are the assignee for the bug.
