GPU crash dump
Hi there,
I am running CentOS 7 on an Intel NUC7i3BNH with with KVM/QEMU using GPU
virtualization passthrough to a Windows 10 VM.
Kernel is 5.1.9 compiled with merged configs from standard CentOS kernel 3.10.x
and 5.1.9 kernel-ml from elrepo-kernel.
I am getting random bluescreen in Windows (also with standard CentOS 3.10.x
kernels) and kernel messages containing "gvt: guest page write error" and "gvt:
vgpu(1) Invalid FORCE_NONPRIV write" and "gvt: vgpu 1: fail: spt" and "gvt:
vgpu 1: fail: shadow page" and others as well as
Jun 16 13:38:30 floor13 kernel: [drm] GPU hangs can indicate a bug anywhere in
the entire gfx stack, including userspace.
Jun 16 13:38:30 floor13 kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Jun 16 13:38:30 floor13 kernel: [drm] drm/i915 developers can then reassign to
the right component if it's not a kernel issue.
Jun 16 13:38:30 floor13 kernel: [drm] The gpu crash dump is required to analyze
gpu hangs, so please always attach it.
Jun 16 13:38:30 floor13 kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
which is why I am here :)
I will attach kernel messages containing gvt stuff as well as the GPU crash
dump.
Thanks in advance for your much appereciated work!
