MUBUF insructions calculate their addresses as follows:

index = (IDXEN ? vgpr_idx : 0) + (const_add_tid_en ? TID : 0) offset = (OFFEN ? vgpr_off : 0) + inst_off

/ ====================== LINEAR ADDRESSING ====================== / VADDR = base + sgpr_off + offset + stride * index

/ ===================== SWIZZLED ADDRESSING ===================== / index_msb = index / const_index_stride index_lsb = index % const_index_stride offset_msb = offset / const_element_size offset_lsb = offset % const_element_size buffer_offset = ((index_msb * stride + offset_msb * const_element_size) * const_index_stride + index_lsb * const_element_size + offset_lsb)

VADDR = base + sgpr_off + buffer_offset

first we calculate the buffer's index and offset. these will be used for either linear or swizzled buffers.

Range check behavior causes out of range accesses to to be treated differently. Out of range accesses return 0 for loads and are ignored for stores. For non-formatted accesses, this is done on a per-lane basis.
