- drm/nouveau/gr/gf100-: port tile mapping calculations from NVGPU · 5f6474a4
  Ben Skeggs authored May 08, 2018
```
There's also a couple of hardcoded tables for a couple of very specific
configurations that NVGPU's algorithm didn't work for.

RM and NVGPU both have a variant of this, we probably should too.

- drm/nouveau/gr/gf100-: virtualise dist_skip_table + improve algorithm · 60770fa2
  Ben Skeggs authored May 08, 2018
```
The algorithm for GM200 and newer matches RM for all the boards I have, but
I don't have enough data to try and figure something out for earlier boards,
so these will still write zeroes to the table as we did before.

The code in NVGPU isn't helpful here, it appears to handle specific cases.

I don't think this is done after Fermi, NVGPU used to do it but removed
the code, and I've not seen RM traces touching it either.

  Ben Skeggs authored May 08, 2018
```
I haven't yet been able to find a fully programatic way of calculating the
same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends
on data tables for specific configurations.

I couldn't find traces for every possibility, so the algorithm will switch
to a mapping similar to what GK104-GM10x use if it encounters one.  We did
the wrong thing before anyway, so shouldn't matter too much.

The algorithm used in the GK104 implementation was ported from NVGPU.
