| * This occurs when a different function (func2,3) is being marked |
| * as "scan-off". Real-life scenario for example: if a driver is being |
| * load-unloaded while func6,7 are down. This will cause the timer to access |
| * the ilt, translate to a logical address and send a request to read/write. |
| * Since the ilt for the function that is down is not valid, this will cause |
| * a translation error which is unrecoverable. |
| * The Workaround is intended to make sure that when this happens nothing fatal |
| * will occur. The workaround: |
| * 1. First PF driver which loads on a path will: |
| * a. After taking the chip out of reset, by using pretend, |
| * it will write "0" to the following registers of |
| * the other vnics. |
| * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0); |
| * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0); |
| * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0); |
| * And for itself it will write '1' to |
| * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable |
| * dmae-operations (writing to pram for example.) |
| * note: can be done for only function 6,7 but cleaner this |
| * way. |
| * b. Write zero+valid to the entire ILT. |
| * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of |
| * VNIC3 (of that port). The range allocated will be the |
| * entire ILT. This is needed to prevent ILT range error. |
| * 2. Any PF driver load flow: |
| * a. ILT update with the physical addresses of the allocated |
| * logical pages. |
| * b. Wait 20msec. - note that this timeout is needed to make |
| * sure there are no requests in one of the PXP internal |
| * queues with "old" ILT addresses. |
| * c. PF enable in the PGLC. |
| * d. Clear the was_error of the PF in the PGLC. (could have |
| * occured while driver was down) |
| * e. PF enable in the CFC (WEAK + STRONG) |
| * f. Timers scan enable |
| * 3. PF driver unload flow: |
| * a. Clear the Timers scan_en. |
| * b. Polling for scan_on=0 for that PF. |
| * c. Clear the PF enable bit in the PXP. |
| * d. Clear the PF enable in the CFC (WEAK + STRONG) |
| * e. Write zero+valid to all ILT entries (The valid bit must |
| * stay set) |
| * f. If this is VNIC 3 of a port then also init |
| * first_timers_ilt_entry to zero and last_timers_ilt_entry |
| * to the last enrty in the ILT. |
| * |
| * Notes: |
| * Currently the PF error in the PGLC is non recoverable. |
| * In the future the there will be a recovery routine for this error. |
| * Currently attention is masked. |
| * Having an MCP lock on the load/unload process does not guarantee that |
| * there is no Timer disable during Func6/7 enable. This is because the |
| * Timers scan is currently being cleared by the MCP on FLR. |
| * Step 2.d can be done only for PF6/7 and the driver can also check if |
| * there is error before clearing it. But the flow above is simpler and |
| * more general. |
| * All ILT entries are written by zero+valid and not just PF6/7 |
| * ILT entries since in the future the ILT entries allocation for |
| * PF-s might be dynamic. |
