8 .. _amdgpu_synid_gfx90a_vdata_999247:
13 Input data for an atomic instruction.
15 Optionally, this operand may be used to store output data:
17 * If :ref:`glc<amdgpu_synid_glc>` is specified, gets the memory value before the operation.
19 *Size:* depends on :ref:`dmask<amdgpu_synid_dmask>`:
21 * :ref:`dmask<amdgpu_synid_dmask>` may specify 2 data elements for 32-bit-per-pixel surfaces or 4 data elements for 64-bit-per-pixel surfaces. Each data element occupies 1 dword.
24 Note: the surface data format is indicated in the image resource constant, but not in the instruction.
26 *Operands:* :ref:`v<amdgpu_synid_v>`, :ref:`a<amdgpu_synid_a>`
