Hey,
knowing that we're starting to have serious issues with figuring out what
features the given device supports and what api's/extensions can be reasonably
implemented on top of it I've spent the weekend trying to define feature
levels. Feature levels were effectively defined by the Direct3D version
numbers.
Attached is a patch and documentation for the feature levels. I'm also
attaching gallium_feature_levels.rst file which documents what each feature
level means and what apis can be reasonably supported by each (I figured it's
going to be easier to look at it outside the diff).
There's a few features that are a bit problematic, in no particular order:
- unnormalized coordinates, we don't even have a cap for those right now but
since that feature doesn't exist in direct3d (all coords are always normalized
in d3d) the support for it is hard to define in term of a feature level
- two-sided stencil - d3d supports it in d3d10 but tons of hardware supported
it earlier
- extra mirror wrap modes - i don't think mirror repeat was ever supported and
mirror clamp was removed in d3d10 but it seems that some hardware kept support
for those
- shadow maps - it's more of an "researched guess" since it's largely based on
a format support, but as far as i can tell all d3d10 hardware supports it,
earlier it varies (e.g. nvidia did it for ages)
I think the other stuff is acceptable. Take a look at the docs and let me know
what you think.

+*1) There is no distinction between pre-multiplied alpha or non-premultiplied
+alpha in Direct3D 10. DXT formats have been replaced by BC formats, so DXT1 == BC1,
+DXT2,DXT3 == BC2 and DXT4,DXT5 == BC3 (bc for block compression)
+*2) There's lots of ways of performing shadow mapping but what we refer to is simply
+the ability to sample & filter from a depth texture. This ability is format dependent
+and therefore doesn't strickly adhere to the feature levels but all major vendors
+(NVIDIA, AMD, Intel) seem to support it in their DX10 level GPUs.
+*3) It's part of the functionality a driver can support or not. At least for DX9 level
+drivers. I'm not sure what happened with it afterwards.

*1) There is no distinction between pre-multiplied alpha or non-premultiplied
alpha in Direct3D 10. DXT formats have been replaced by BC formats, so DXT1 ==
BC1,
DXT2,DXT3 == BC2 and DXT4,DXT5 == BC3 (bc for block compression)
*2) There's lots of ways of performing shadow mapping but what we refer to is
simply
the ability to sample & filter from a depth texture. This ability is format
dependent
and therefore doesn't strickly adhere to the feature levels but all major
vendors
(NVIDIA, AMD, Intel) seem to support it in their DX10 level GPUs.
*3) It's part of the functionality a driver can support or not. At least for
DX9 level
drivers. I'm not sure what happened with it afterwards.
