8 .. _amdgpu_synid9_data_mimg_atomic_reg:
11 ===========================
13 Input data for an atomic instruction.
15 Optionally may serve as an 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>` and :ref:`tfe<amdgpu_synid_tfe>`:
21 * :ref:`dmask<amdgpu_synid_dmask>` may specify 1 data element for 32-bit-per-pixel surfaces or 2 data elements for 64-bit-per-pixel surfaces. Each data element occupies 1 dword.
22 * :ref:`tfe<amdgpu_synid_tfe>` adds 1 dword if specified.
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>`
