/** |
* 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; |
