| Texture upload performance tests |
| |
| Tests: |
| + dEQP-GLES2.performance.texture.upload.* |
| |
| Includes: |
| + All legal format-type-combinations |
| - ALPHA, RGB, RGBA, LUMINANCE and LUMINANCE_ALPHA for UNSIGNED_BYTE |
| - RGB for UNSIGNED_SHORT_5_6_5 |
| - RGBA for UNSIGNED_SHORT_4_4_4_4 and UNSIGNED_SHORT_5_5_5_1 |
| + Upload functions glTexImage2D and glTexSubImage2D |
| + Different texture sizes from 16x16 to 2048x2048 |
| - Including npot texture (257x257) |
| + Measurements for: |
| - Upload call only |
| - Upload and draw with uploaded texture + buffer swap |
| |
| Excludes: |
| + Different pixel unpack alignments |
| + Trashed cache before upload |
| |
| Description: |
| |
| Texture upload performance cases measure the performance of texture upload |
| calls. Subgroup 'upload' measures the duration of upload calls (i.e. |
| recorded iteration time includes only multiple texture upload calls). |
| Subgroup 'upload_draw_swap' draws a quad with the uploaded texture after |
| each upload and swaps buffers afterwards (i.e. recorded iteration time |
| includes multiple upload and draw calls and one buffer swap). Texture |
| sizes vary from 16x16 to 2048x2048 and include an npot texture with size |
| 257x257. Viewport size is held constant at 64x64. |
| |
| The amount of draw calls is automatically calibrated to find a workload |
| that produces approximately 30fps. Result is reported as uploaded MTex/s. |
| |
| See performance.txt for more details on performance testing. |
