Re: [PATCH] drm/amdgpu: Add more page fault info printing for GFX10
Hi Yong,
that is an intentional differentiation.
The values behind the ":" are hardware values from the page faults
interrupt vector.
All values printed without the ":" are additional things we get from the
kernel task information based on the pasid.
Please keep that,
Christian.

Hi Christian,
I feel with ":" it is better, because without it I found it is not easy
to interpret the printing. Moreover, it continues the format of the
former part.
It looks like this:

If you are not convinced, I can change it to without ":".

That should probably be a separate patch since it is fixing gfx9.
