S_STOPPED

S_RUNNING
S_STALLED
S_STALLED_SLEEP
S_WAITCNT	wavefront has unsatisfied wait counts while in this state the WF will only execute if the oldest instruction is the waitcnt. while in S_WAITCNT, the wavefront will not be ready until all of its waitcnts have been satisfied. the scoreboard ready() function will check the status of the waitcnts whenever the WF is in S_WAITCNT, and once they are satisfied, it will resume normal operation.
S_BARRIER	WF is stalled at a barrier.

◆ exec()

void gem5::Wavefront::exec ( )

if this wave is in S_WAITCNT state, then it should enter exec() precisely one time before the waitcnts are satisfied, in order to execute the waitcnt instruction itself thus we assert that the waitcnt is the oldest instruction. if we enter exec() with active waitcnts, and we're not executing the waitcnt instruction, something must be wrong

we return here to avoid spurious errors related to flat insts and their address segment resolution.

◆ initRegState()

void gem5::Wavefront::initRegState	(	HSAQueueEntry *	task,
		int	wgSizeInWorkItems
	)

Since flat scratch init is needed for this kernel, this kernel is going to have flat memory instructions and we need to initialize the hidden private base for this queue. scratch_resource_descriptor[0] has this queue's scratch base address. scratch_backing_memory_location has the offset to this queue's scratch base address from the SH_HIDDEN_PRIVATE_BASE_VMID. Ideally, we only require this queue's scratch base address for address calculation (stored in scratch_resource_descriptor[0]). But that address calculation shoule be done by first finding the queue's scratch base address using the calculation "SH_HIDDEN_PRIVATE_BASE_VMID + offset". So, we initialize SH_HIDDEN_PRIVATE_BASE_VMID.

For more details see: http://rocm-documentation.readthedocs.io/en/latest/ ROCm_Compiler_SDK/ROCm-Native-ISA.html#flat-scratch

https://github.com/ROCm-Developer-Tools/ ROCm-ComputeABI-Doc/blob/master/AMDGPU-ABI.md #flat-addressing

the compute_tmpring_size_wavesize specifies the number of kB allocated per wavefront, hence the multiplication by 1024.

to get the per wavefront offset into the scratch memory, we also multiply this by the wfId. the wfId stored in the Wavefront class, however, is the wave ID within the WG, whereas here we need the global WFID because the scratch space will be divided amongst all waves in the kernel. to get the global ID we multiply the WGID by the WG size, then add the WFID of the wave within its WG.
