6636 | * This occurs when a different function (func2,3) is being marked | |
6637 | * as "scan-off". Real-life scenario for example: if a driver is being | |
6638 | * load-unloaded while func6,7 are down. This will cause the timer to access | |
6639 | * the ilt, translate to a logical address and send a request to read/write. | |
6640 | * Since the ilt for the function that is down is not valid, this will cause | |
6641 | * a translation error which is unrecoverable. | |
6642 | * The Workaround is intended to make sure that when this happens nothing fatal | |
6643 | * will occur. The workaround: | |
6644 | * 1. First PF driver which loads on a path will: | |
6645 | * a. After taking the chip out of reset, by using pretend, | |
6646 | * it will write "0" to the following registers of | |
6647 | * the other vnics. | |
6648 | * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0); | |
6649 | * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0); | |
6650 | * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0); | |
6651 | * And for itself it will write '1' to | |
6652 | * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable | |
6653 | * dmae-operations (writing to pram for example.) | |
6654 | * note: can be done for only function 6,7 but cleaner this | |
6655 | * way. | |
6656 | * b. Write zero+valid to the entire ILT. | |
6657 | * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of | |
6658 | * VNIC3 (of that port). The range allocated will be the | |
6659 | * entire ILT. This is needed to prevent ILT range error. | |
6660 | * 2. Any PF driver load flow: | |
6661 | * a. ILT update with the physical addresses of the allocated | |
6662 | * logical pages. | |
6663 | * b. Wait 20msec. - note that this timeout is needed to make | |
6664 | * sure there are no requests in one of the PXP internal | |
6665 | * queues with "old" ILT addresses. | |
6666 | * c. PF enable in the PGLC. | |
6667 | * d. Clear the was_error of the PF in the PGLC. (could have | |
2de67439 | 6668 | * occurred while driver was down) |
619c5cb6 VZ |
6669 | * e. PF enable in the CFC (WEAK + STRONG) |
6670 | * f. Timers scan enable | |
6671 | * 3. PF driver unload flow: | |
6672 | * a. Clear the Timers scan_en. | |
6673 | * b. Polling for scan_on=0 for that PF. | |
6674 | * c. Clear the PF enable bit in the PXP. | |
6675 | * d. Clear the PF enable in the CFC (WEAK + STRONG) | |
6676 | * e. Write zero+valid to all ILT entries (The valid bit must | |
6677 | * stay set) | |
6678 | * f. If this is VNIC 3 of a port then also init | |
6679 | * first_timers_ilt_entry to zero and last_timers_ilt_entry | |
6680 | * to the last enrty in the ILT. | |
6681 | * | |
6682 | * Notes: | |
6683 | * Currently the PF error in the PGLC is non recoverable. | |
6684 | * In the future the there will be a recovery routine for this error. | |
6685 | * Currently attention is masked. | |
6686 | * Having an MCP lock on the load/unload process does not guarantee that | |
6687 | * there is no Timer disable during Func6/7 enable. This is because the | |
6688 | * Timers scan is currently being cleared by the MCP on FLR. | |
6689 | * Step 2.d can be done only for PF6/7 and the driver can also check if | |
6690 | * there is error before clearing it. But the flow above is simpler and | |
6691 | * more general. | |
6692 | * All ILT entries are written by zero+valid and not just PF6/7 | |
6693 | * ILT entries since in the future the ILT entries allocation for | |
6694 | * PF-s might be dynamic. | |
