Bug ID: 193341
Summary: AMDGPU: kernel NULL pointer dereferenced with hybrid
graphics
Product: Drivers
Version: 2.5
Kernel Version: 4.9.6
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: stefan.kohek@um.si
Regression: No
Created attachment 253261
--> https://bugzilla.kernel.org/attachment.cgi?id=253261&action=edit
Kernel config, output of dmesh (with stack trace), output of lspci
The driver crashes when AMDGPU is used with a combination of R5 M230 and
MULLINS.
The driver work with MULLINS OK, when discrete GPU (01:00.0 R5 M230) is
disabled (in bios).
Kernel: Linux LenovoPC 4.9.6-1-ARCH #1 SMP PREEMPT Thu Jan 26 09:22:26 CET 2017
x86_64 GNU/Linux
Relevant config:
CONFIG_DRM_AMDGPU=m
CONFIG_DRM_AMDGPU_SI=y
CONFIG_DRM_AMDGPU_CIK=y
CONFIG_DRM_AMDGPU_USERPTR=y
I understand this is experimental case. Anyway, maybe somebody will fix it.
This case work OK with RADEON driver (even offloading).

Greetings,
I am the original reported on Freedesktop bug report. I have a similar hardware
in this case Kaveri and R5 M230 (Hainan or Jet Pro).
The fix as mentioned on comment #5 is working fine.

I'm not sure if all attached fixes were merged to kernel 4.10.1, but now I get
different error (when trying to use the discrete GPU).

Make sure your kernel has this patch:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c10c8f7c27103bd7ac02d041d9d6e97296d48fc1

With this path is working fine. Thank you.
Shader heavy games are now rendering twice as fast.
