            Bug ID: 99579
           Summary: [radeonsi,regression] Hardware-accelerated video
                    playback with mpv spams console with
                    "r600_texture_transfer_map - failed to create
                    temporary texture to hold untiled copy"
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Keywords: bisect_pending, regression
          Severity: normal
          Priority: high
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: kai at dev.carbon-project.org

Since updating Mesa from 494b63f52541936e7b0357534ee0fd2444319501 to
7c5629a26912af9164bda17b7af5370f6b4302e4 I see the following error spammed to
the console when playing back any video with mpv and hardware acceleration
(VA-API and VDPAU are both affected):
> EE ../../../../../src/gallium/drivers/radeon/r600_texture.c:1571 r600_texture_transfer_map - failed to create temporary texture to hold untiled copy
Only when I set --hwdec=no and --vo to something other than "vaapi" or "vdpau"
I can avoid this error. dmesg is clear and shows no error.

I'm using the following mpv and FFmpeg versions (all from their respective
Debian packages):
mpv 0.23.0
ffmpeg library versions:
   libavutil       55.34.100
   libavcodec      57.64.101
   libavformat     57.56.100
   libswscale      4.2.100
   libavfilter     6.65.100
   libswresample   2.3.100
ffmpeg version: 3.2.2-1

The graphics stack used (Debian testing as a base) was:
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
Mesa: Git:master/7c5629a269 + the modified version of attachment 127812
libdrm: Git:master/d4b8344363 (tag libdrm-2.4.75)
LLVM: SVN:trunk/r293339 (5.0 devel) +
<https://reviews.llvm.org/D26348?download=true>
X.Org: 2:1.19.0-3
Linux: 4.9.6
Firmware: 20161130-2
libclc: Git:master/2ec7d80d5e
DDX (amdgpu): 1.2.0-1+b1

Let me know, if you need anything else (besides a bisect).
