[Mesa-dev] [RFC 00/10] Enable support for 2D ASTC HDR and LDR formats

[Ilia Mirkin]

Hi Nanley,

I was expecting to see some code dealing with the fact that the block
sizes are all different. Did I miss it, or is that still on the TODO
list?

Cheers,

P.S. Congrats on your first public patch submission to mesa-dev :)
