Hello,
Why is that gallium overwrites any existing mipmap mag/min
filters when aniso is set?
Here is the relevant bits from
mesa/src/mesa/state_tracker/st_atom_sampler.c (commit
98ae83d5cc73b61826823c915b5c59746c2e85c7)
...
if (sampler->max_anisotropy > 1.0) {
sampler->min_img_filter = PIPE_TEX_FILTER_ANISO;
sampler->mag_img_filter = PIPE_TEX_FILTER_ANISO;
}
This assumes that all hardware use a different filter
for mipmap versus ansio. This is not the case for nvidia
since ansio is set separately from the mipmap min/mag
filters.
