| 1492 | * |
| 1493 | * We have the following requirements for issuing firmware commands: |
| 1494 | * - Some commands require that the packet transmit path is idle when |
| 1495 | * the command is issued. (For simplicity, we'll just quiesce the |
| 1496 | * transmit path for every command.) |
| 1497 | * - There are certain sequences of commands that need to be issued to |
| 1498 | * the hardware sequentially, with no other intervening commands. |
| 1499 | * |
| 1500 | * This leads to an implementation of a "firmware lock" as a mutex that |
| 1501 | * can be taken recursively, and which is taken by both the low-level |
| 1502 | * command submission function (mwl8k_post_cmd) as well as any users of |
| 1503 | * that function that require issuing of an atomic sequence of commands, |
| 1504 | * and quiesces the transmit path whenever it's taken. |
