            Bug ID: 91110
           Summary: Textures missing iff character in specific areas in
                    dolphin running Xenoblades Chronicles
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
               URL: https://code.google.com/p/dolphin-emu/issues/detail?id
                    =8688
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: christian@madez.de
        QA Contact: dri-devel@lists.freedesktop.org

Iff a character is in specific areas some textures on him are not rendered. In
the entry of colony 9 is such an area.

The textures are rendered properly on the Intel GPU.

There are screenshots, a fifolog and an apitrace at the end of the linked
bugreport.

The problem appears in Debian Jessie, Sid and mesa-git the last time checked,
which was 9 days ago.

I compiled mesa-git with

CFLAGS = -g -O2 -Wall -std=c99 -Werror=implicit-function-declaration
-Werror=missing-prototypes -fno-strict-aliasing -fno-builtin-memcmp -DDEBUG

and set

$ export LIBGL_DEBUG=verbose
$ export MESA_DEBUG=1
$ export EGL_LOG_LEVEL=debug

before running dolphin. Running dolphin with the game until the issue appears
gives the following output

$ dolphin-emu
Gtk-Message: Failed to load module "canberra-gtk-module"
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 22: 1002:679a, driver radeonsi

I'm sorry, I don't know how to write a simple GLUT-based test program.

I can't reproduce this problem on Kaveri, the apitrace plays back correctly.
Maybe the problem is Tahiti specific.

Does setting the environment variable R600_DEBUG=switch_on_eop work around the
problem when playing back the apitrace or running the game?

No.

I tested the replay of the trace and the game both with mesa from Sid and
mesa-git, each time with R600_DEBUG=switch_on_eop set. The issue remained
unaffected.

Are you sure you meant R600_DEBUG=switch_on_eop? I'm asking because I'm using
radeonsi.

r600 and radeonsi share the same R600_DEBUG.

Apparently the apitrace file has been deleted. Can you upload it again? Some
people use google drive for apitraces for instance.

--- Comment #7 from Timothy Arceri <t_arceri@yahoo.com.au> ---
apitrace never reuploaded. Given the age of the bug and no follow-up bug
reports I'm just going to close this bug as invalid.

Feel free to reopen if it is still a problem, adding a fresh apitrace and
updated information.
