125 | * Generic queue structure | |

4ce7cc2b JB |
127 | * Contains common data for Rx and Tx queues. |
128 | * | |
129 | * Note the difference between n_bd and n_window: the hardware | |
130 | * always assumes 256 descriptors, so n_bd is always 256 (unless | |
131 | * there might be HW changes in the future). For the normal TX | |
132 | * queues, n_window, which is the size of the software queue data | |
133 | * is also 256; however, for the command queue, n_window is only | |
134 | * 32 since we don't need so many commands pending. Since the HW | |
135 | * still uses 256 BDs for DMA though, n_bd stays 256. As a result, | |
136 | * the software buffers (in the variables @meta, @txb in struct | |
137 | * iwl_tx_queue) only have 32 entries, while the HW buffers (@tfds | |
138 | * in the same struct) have 256. | |
139 | * This means that we end up with the following: | |
140 | * HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 | | |
141 | * SW entries: | 0 | ... | 31 | | |
142 | * where N is a number between 0 and 7. This means that the SW | |
143 | * data is a window overlayed over the HW queue. | |
