- /* Comment ported from amdvlk -
- * If we have the following image:
- * Uncompressed pixels Compressed block sizes (4x4)
- * mip0: 22 x 22 6 x 6
- * mip1: 11 x 11 3 x 3
- * mip2: 5 x 5 2 x 2
- * mip3: 2 x 2 1 x 1
- * mip4: 1 x 1 1 x 1
- *
- * On GFX9 the descriptor is always programmed with the WIDTH and HEIGHT of the base level and the HW is
- * calculating the degradation of the block sizes down the mip-chain as follows (straight-up
- * divide-by-two integer math):
- * mip0: 6x6
- * mip1: 3x3
- * mip2: 1x1
- * mip3: 1x1
- *
- * This means that mip2 will be missing texels.
- *
- * Fix this by calculating the base mip's width and height, then convert that, and round it
- * back up to get the level 0 size. Take the max of the converted size and the scaled up size.
