            Bug ID: 101996
           Summary: Having problems when drawing lots of mesh with texture
                    array
           Product: Mesa
           Version: 17.2
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org

Hi,

I'm developing a new engine for game STK, and is having serious regression when
switching to use texture array for drawing meshes in game:

Code:
https://github.com/Benau/stk-code/tree/sp_new
(Basically only data/shader/sp*.* and src/sp/* is relevant

Assets:
https://github.com/Benau/sp-assets
(In case if real-time testing is needed)

Apitrace:
http://kobato.stan.hk/bug.trace.lzma

Linux is 4.12.4
DRM is using git
Mesa version  is 17.2.0-rc1 (git-a455f594bb)

So when you enter the game with lots of meshes rendering, the game is spending
a lot of time waiting in glFlush,
(~100ms at worst)
in util_queue_fence_wait in gdb with ctrl-c,
Full trace:

The same code has been tested in windows in same hardware, and other PC with
nvidia proprietary driver, and it's working fine.

Did I do something wrong with opengl code, or do you think it's a problem in
mesa somewhere?

Thanks
