| 3900 | * |
| 3901 | * Each command that is issued to the FW, whether IO commands from the OS or |
| 3902 | * internal commands like IOCTLs, are wrapped in local data structure called |
| 3903 | * megasas_cmd. The frame embedded in this megasas_cmd is actually issued to |
| 3904 | * the FW. |
| 3905 | * |
| 3906 | * Each frame has a 32-bit field called context (tag). This context is used |
| 3907 | * to get back the megasas_cmd from the frame when a frame gets completed in |
| 3908 | * the ISR. Typically the address of the megasas_cmd itself would be used as |
| 3909 | * the context. But we wanted to keep the differences between 32 and 64 bit |
| 3910 | * systems to the mininum. We always use 32 bit integers for the context. In |
| 3911 | * this driver, the 32 bit values are the indices into an array cmd_list. |
| 3912 | * This array is used only to look up the megasas_cmd given the context. The |
| 3913 | * free commands themselves are maintained in a linked list called cmd_pool. |
