            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.

Apitrace: https://drive.google.com/open?id=0Bze7CJKD12nORWQ4RTdIbk4zT1k

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...

The stalls were reduced a lot in February 2016, but they didn't disappear
completely.

--- 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.
