vdata
|
|
===========================
|
|
|
|
Input data for an atomic instruction.
|
|
|
|
Optionally may serve as an output data:
|
|
|
|
* If :ref:`glc<amdgpu_synid_glc>` is specified, gets the memory value before the operation.
|
|
|
|
*Size:* depends on :ref:`dmask<amdgpu_synid_dmask>` and :ref:`tfe<amdgpu_synid_tfe>`:
|
|
|
|
* :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.
|
|
* :ref:`tfe<amdgpu_synid_tfe>` adds 1 dword if specified.
|
|
|
|
Note. The surface data format is indicated in the image resource constant but not in the instruction.
|
|
|
|
*Operands:* :ref:`v<amdgpu_synid_v>`
