Bug ID: 91969 Summary: [radeonsi][bonaire] Stalls with Borderlands 2 Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: shawn.starr@rogers.com QA Contact: dri-devel@lists.freedesktop.org
kernel 4.3.0-rc0 (Fedora snapshot) mesa git master / with also experimental radeonsi shader cache (still stalls with it even) LLVM trunk (Sept 10th, 2015 build)
I've done some profiling of Borderlands 2 (just the menu intro) and discovered what may be causing the stalls.

--- Comment #6 from Andreas Hartmetz ahartmetz@gmail.com --- Is this fixed now? I've had the same or a similar problem and it's fixed now. I thought it wasn't fixed for a while until I discovered that limiting the frame rate to 60 is really bad for performance in Borderlands 2...

--- Comment #8 from Timothy Arceri t_arceri@yahoo.com.au --- radeonsi now has an end-to-end shader cache and glthreading which is enabled by default for Borderlands 2. These issues should now be mostly gone, there is not too much more that can be done. Closing.
