            Bug ID: 98724
           Summary: garbled output using glDrawElementsIndirect
           Product: Mesa
           Version: git
          Hardware: Other
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: logan@bacoosta.com
        QA Contact: dri-devel@lists.freedesktop.org

I work on an N64 emulator (GLupeN64). I received a report from a user that they
had garbled output from the application. They tried it with llvmpipe and it
worked.

The issue report is here:
https://github.com/loganmc10/GLupeN64/issues/102

It includes and apitrace and a screenshot.

I had him disable indirect drawing, and in that mode the application will use
glDrawElementsBaseVertex instead of glDrawElementsIndirect. He said that that
fixed the issue, but it was very slow.

api traces

Hi, I am the original reporter. At Logan's request, I'm uploading an archive
with apitraces when I was using llvmpipe and when I was using radeonsi. In both
cases, GLupeN64 was compiled with DEBUG=1 in the makefile.

Hi Aaron, thanks for the traces. The playback of both traces looks fine to me
on Tonga. So either this has been fixed very recently, or it's
SI/Oland-specific.

I'm curious, could you please post your dmesg and the output of sha1sum $(find
/lib/firmware -iname *oland*)?

dmesg

I use mesa-git nightly builds, and I can confirm the issue is still present as
of commit a456ea17fb460a68e28c13dd4b7086dc4309f410. I've also tested a
4.9+amdgpu kernel, but I get the same issue. It could very well be an SI
problem.

I'm attaching a dmesg log, and here's the checksums for my firmware.
