Johannes Berg4ce7cc22011-05-13 11:57:40 -0700124 * Contains common data for Rx and Tx queues.
125 *
126 * Note the difference between n_bd and n_window: the hardware
127 * always assumes 256 descriptors, so n_bd is always 256 (unless
128 * there might be HW changes in the future). For the normal TX
129 * queues, n_window, which is the size of the software queue data
130 * is also 256; however, for the command queue, n_window is only
131 * 32 since we don't need so many commands pending. Since the HW
132 * still uses 256 BDs for DMA though, n_bd stays 256. As a result,
133 * the software buffers (in the variables @meta, @txb in struct
134 * iwl_tx_queue) only have 32 entries, while the HW buffers (@tfds
135 * in the same struct) have 256.
136 * This means that we end up with the following:
137 * HW entries: | 0 | ... | N * 32 | ... | N * 32 + 31 | ... | 255 |
138 * SW entries: | 0 | ... | 31 |
139 * where N is a number between 0 and 7. This means that the SW
140 * data is a window overlayed over the HW queue.
