           Summary: blackscreen after modprobe amdgpu on R9M370X mac
                    edition
           Product: DRI

            Status: NEW
          Severity: blocker
          Priority: medium

dmesg after `modprobe amdgpu` and getting blackscreen

I don't know if this is specific to R9M370X - mac edition but I couldn't
reproduce it on other AMD PC I have.

This is fairly simple to reproduce, I just have to mount the amdgpu and I get a
black screen on my main screen and my main screen only (my second screen is
fine)

I don't have this problem using radeon with the exact same kernel config.
dmesg is saying everything is fine and X11 log is irrelevant because it happen
_before_ startx.
I am using Linux 4.12.4-gentoo.

My kernel .config

note that I disabled the intel driver and the runtime gpu switch despite the
fact that 2015 MBP have an internal intel GPU but this bug is also reproducible
with it.

I don't see any problems with the driver load.  The display switching is
handled by a proprietary mechanism independent of the GPU driver on macs.  I'm
not sure what the status of that support is.  I think your problem is likely
related to that.

Sorry. I didn't realize this worked on radeon.

I cloned "~agd5f/linux" on the branch "drm-next-4.14-wip" and copied my .config
from the 4.12.4 I was using.
`uname -r` give me "4.12.0-rc7+"

Now `modprobe amdgpu` is freezing my screen instead of blackscreen.
`dmesg | grep amdgpu -i` give this :

[  107.804074] [drm] amdgpu kernel modesetting enabled.
[  107.804109] fb: switching to amdgpudrmfb from EFI VGA
[  107.804672] amdgpu 0000:01:00.0: SI support provided by radeon.
[  107.804674] amdgpu 0000:01:00.0: Use radeon.si_support=0 amdgpu.si_support=1
to override.

Using 4.12.4 my second screen was fine, that isn't the case anymore with
drm-next-4.14-wip.
Using 4.12.4 I could startx (with a second screen obviously, my main screen was
remaining black) now startx seems to return "no screen found".


Note that radeon is still working perfectly.

git apply returned me:
"error: patch failed: drivers/gpu/drm/amd/amdgpu/si.c:1413
error: drivers/gpu/drm/amd/amdgpu/si.c: patch does not apply"

So I checked manually:
1413                 amdgpu_program_register_sequence(adev,
1414                                                  pitcairn_mgcg_cgcg_init,
1415                                                  (const
u32)ARRAY_SIZE(pitcairn_mgcg_cgcg_init));
1416                 break;
1417

1438                 amdgpu_program_register_sequence(adev,
1439                                                  oland_mgcg_cgcg_init,
1440                                                  (const
u32)ARRAY_SIZE(oland_mgcg_cgcg_init));
1441                 break;
1442         case CHIP_HAINAN:
1443


The two break are already there. I checked if I cloned what you said:
`git branch` return
"* drm-next-4.14-wip"
I also checked using git log and the patch
e5c8d400da67abc1c033b9a4af1806926b55e5f6 is already in the list

PS: I'm very far from being a git expert so maybe I got something wrong and not
cloned the good one ?

The patch is already there in my 4.14-wip branch, but you seem to be having
other problems with that kernel, so I suggested that patch if you want to try
the patch on an older kernel that works better.

Having this patch or not on 4.12.4 does not change anything (at least on this
bug)

Follow this advice and set radeon.si_support=0 amdgpu.si_support=1 to use the
amdgpu driver. (In exchange, you no longer need to blacklist the radeon driver)
