| /** |
| * This file contains macros for building command buffers in memory. |
| * |
| * Use NEW_CB for buffers with a varying size and it will also allocate |
| * the buffer. |
| * Use BEGIN_CB for arrays with a static size. |
| * |
| * Example: |
| * |
| * uint32_t cb[3]; |
| * CB_LOCALS; |
| * |
| * BEGIN_CB(cb, 3); |
| * OUT_CB_REG_SEQ(R500_RB3D_CONSTANT_COLOR_AR, 2); |
| * OUT_CB(blend_color_red_alpha); |
| * OUT_CB(blend_color_green_blue); |
| * END_CB; |
| * |
| * And later: |
| * |
| * CS_LOCALS; |
| * WRITE_CS_TABLE(cb, 3); |
| * |
| * Or using a little slower variant: |
| * |
| * CS_LOCALS; |
| * BEGIN_CS(cb, 3); |
| * OUT_CS_TABLE(cb, 3); |
| * END_CS; |
