The printing we did for GFX9 was not propogated to GFX10 somehow, so fix
it now.

I think the text actually looks better without the ":".

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

Apart from that the patch looks good to me,
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:

[  190.686668] amdgpu 0000:03:00.0: [gfxhub0] retry page fault (src_id:0 
ring:0 vmid:8 pasid:32771, for process:kfdtest pid:3273 thread:kfdtest 
pid:3273)

vs without ":"

[  190.686668] amdgpu 0000:03:00.0: [gfxhub0] retry page fault (src_id:0 
ring:0 vmid:8 pasid:32771, for process kfdtest pid 3273 thread kfdtest 
pid 3273)


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


Regards,

Yong

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.
