Patches #11 and #18 are Reviewed-by: Christian König
.
Patch #12 is a NAK, that will also increase the VM space for pre gfx9
and we already found that this isn't a good idea.
We should change how that value is evaluated in the different GMC
handling code instead.
In other words, set it to -1 as default value and handle -1 in gmc
v6/v7/v9 as 64GB, while in gmc v9 as 1TB (or even 256TB?).
Patch #13, #14: Good catch, but please squash into my original patch #8.
Patch #15, #16, #17: Please squash into patch #10.
Apart from that thanks a lot to pick this up while I was busy tracking
the hw problem down.
And BTW did you tested the 48bit (256TB) address space support as well?
That should also work now.
Regards,
Christian.
