            Bug ID: 97861
           Summary: [amdgpu SI] purple line is visible on left side of the
                    screen connected by HDMI
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

the purple line

kernel - 3 days old drm-next-4.9-wip
mesa/llvm/libdrm - latest
xorg - 1.18.4 / ~1.19

I have two displays: DVI monitor, always "on" and HDMI (TV) usually "off". 

When i turn on HDMI screen:
$xrandr --output DVI-I-1 --primary --mode 1680x1050 --output HDMI-A-0 --mode
1920x1080

On left side TV screen appears purple vertical line. 


1) this is 80-90% bug 91041, but amdgpu here and srcreen isn't blurry
$xrandr --output HDMI-A-0 --auto --set audio off
works for me
2) option audio=0 did the job as well 
3) Before Xorg/wayland start tty's are clean&black after X/wayland purple line
is visible.  
4) problem is probably related to hdmi-audio so i don't even know if it's bug
at all

Same problem here, 4.9-rc1, AMD R270X, Xorg 1.18.4, xf86-video-amdgpu from git
master, purple line and the screen is very blurry.

xrandr --output HDMI-A-0 --auto --set audio off

helps, thanks.

I have the same problem. Purple Line on left side and overall blurry screen.
When Audio off, the issues go away.

Same problem on R7 370 except that my monitor shows a black screen and reports
"frequency not supported".

Same problem here with my HDMI screen. Everything works fine (GNOME Wayland
session and all) until I start an X server (not XWayland, actual X server from
a "GNOME on Xorg" session) at which point the screen goes black (X server is
mode-setting I'd imagine), and when it comes back on the purple line is
present.
Logging out of the Xorg session and back into a Wayland session does *not*
revert the problem; I haven't tried the xrandx trick yet.

The screen is indeed blurry (enough to make it unbearable to read any text with
subpixel positioning for more that a few minutes). It might comes from the
scaling of the output to the remaining space (screen space - purple line
space). Furthermore, any screenshot does not capture the line and it's only an
'on screen' thing.

Same issue.  Running 3 monitor set up. 1 monitor HDMI, one monitor HDMI cable
plugged into a DP adapter and one DVI.  Two using the HDMI out have the purple
line, DVI is fine.

Same purple line on my R9 280X

Debian 9.0 (Testing)
Linux 4.10.6 with amdgpu for SI and CIK enabled (From kernel.org)
X.Org 1.19.2, from Debian.

`xrandr --output HDMI-A-0 --auto --set audio off` is a valid workaround, 
though it means that TV outputs have to be on the second display.

I also saw [drm] xxxx: dce_v6_0_afmt_setmode ----no impl !!!!!!!!
every time HDMI sound was enabled.

Is this still an issue with a newer kernel?  Audio support was added to SI
recently.

Tested with yesterdays amd-staging-git-4.11 and the issue seems to be gone.
Looks like we can close this bug when Linux 4.13 is released.
