6555 | * note: can be done for only function 6,7 but cleaner this | |

6559 | * VNIC3 (of that port). The range allocated will be the | |
6560 | * entire ILT. This is needed to prevent ILT range error. | |
6561 | * 2. Any PF driver load flow: | |
6562 | * a. ILT update with the physical addresses of the allocated | |
6563 | * logical pages. | |
6564 | * b. Wait 20msec. - note that this timeout is needed to make | |
6565 | * sure there are no requests in one of the PXP internal | |
6566 | * queues with "old" ILT addresses. | |
6567 | * c. PF enable in the PGLC. | |
6568 | * d. Clear the was_error of the PF in the PGLC. (could have | |
6569 | * occured while driver was down) | |
6570 | * e. PF enable in the CFC (WEAK + STRONG) | |
6571 | * f. Timers scan enable | |
6572 | * 3. PF driver unload flow: | |
6573 | * a. Clear the Timers scan_en. | |
6574 | * b. Polling for scan_on=0 for that PF. | |
6575 | * c. Clear the PF enable bit in the PXP. | |
6576 | * d. Clear the PF enable in the CFC (WEAK + STRONG) | |
6577 | * e. Write zero+valid to all ILT entries (The valid bit must | |
6578 | * stay set) | |
6579 | * f. If this is VNIC 3 of a port then also init | |
6580 | * first_timers_ilt_entry to zero and last_timers_ilt_entry | |
6581 | * to the last enrty in the ILT. | |
6582 | * | |
6583 | * Notes: | |
6584 | * Currently the PF error in the PGLC is non recoverable. | |
6585 | * In the future the there will be a recovery routine for this error. | |
6586 | * Currently attention is masked. | |
6587 | * Having an MCP lock on the load/unload process does not guarantee that | |
6588 | * there is no Timer disable during Func6/7 enable. This is because the | |
6589 | * Timers scan is currently being cleared by the MCP on FLR. | |
6590 | * Step 2.d can be done only for PF6/7 and the driver can also check if | |
6591 | * there is error before clearing it. But the flow above is simpler and | |
6592 | * more general. | |
6593 | * All ILT entries are written by zero+valid and not just PF6/7 | |
6594 | * ILT entries since in the future the ILT entries allocation for | |
6595 | * PF-s might be dynamic. | |
