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

[drm] xxxx: dce_v6_0_afmt_setmode ----no impl !!!!!!!!
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
I have the same problem. Purple Line on left side and overall blurry screen. When Audio off, the issues go away.
Kernel 4.10 RC2
Radeon HD 7970
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.
Forgot the information.
Linux 4.9.11-1-ARCH, X Server 1.19.1 over a R9 280X using amdgpu
I also get the same purple line on the left of a screen connected via HDMI.
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.

dmesg | grep amdpro
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.
