Wave Shared VGPRs Wave64’s can be allocated wave-private and wave-shared VGPRs. Private GPRs are the normal ones where each lane has a unique value. Shared VGPRS are shared between the high and low halves of a wave64. This can be useful to reduce overall VGPR usage when combined with subvector execution. Shared VGPRs are allocated in blocks of 8 Dwords. Shared VGPRs logically occupy the VGPR addresses immediately following the private VGPRs. E.g. if a wave has 8 private VGPRs, they are V0-V7 and shared VGPRs start at V8. If there are 16 shared VGPRs, they are accessed as V8-23. Shared VGPRs cannot be used for: Exports or GDS.

LDS Allocation and Clamping 

LDS is allocated per work-group or per-wavefront when work-groups are not in use. LDS space is allocated to a work-group or wavefront in contiguous blocks of 128 Dwords on 128-Dword alignment. LDS allocations do not wrap around the LDS storage. All accesses to LDS are restricted to the space allocated to that wavefront/work-group. Clamping of LDS reads and writes is controlled by two size registers, which contain values for the size of the LDS space allocated by SPI to this wavefront or work-group, and a possibly smaller value specified in the LDS instruction (size is held in M0). The LDS operations use the smaller of these two sizes to determine how to clamp the read/write addresses.

VGPR Allocation and Alignment

 VGPRs are allocated in groups of four Dwords for wave64, and 8 Dwords for wave32. Operations using pairs of VGPRs (for example: double-floats) have no alignment restrictions. Physically, allocations of VGPRs can wrap around the VGPR memory pool.
