  Ben Skeggs authored May 08, 2018
```
There are differences on GM200 and newer too, but we can't fix them there
as they come from firmware packages.

A request has been made to NVIDIA to release updated firmware.

- drm/nouveau/gr/gf100-: calculate and use sm mapping table · 068cae74
  Ben Skeggs authored May 08, 2018
```
There's a number of places that require this data, so let's separate out
the calculations to ensure they remain consistent.

This is incorrect for GM200 and newer, but will produce the same results
as we did before.

  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.

- drm/nouveau/gr/gf100-: virtualise alpha_beta_tables + improve algorithms · 43952c6f
  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.
