7078 | * This occurs when a different function (func2,3) is being marked | |
7079 | * as "scan-off". Real-life scenario for example: if a driver is being | |
7080 | * load-unloaded while func6,7 are down. This will cause the timer to access | |
7081 | * the ilt, translate to a logical address and send a request to read/write. | |
7082 | * Since the ilt for the function that is down is not valid, this will cause | |
7083 | * a translation error which is unrecoverable. | |
7084 | * The Workaround is intended to make sure that when this happens nothing fatal | |
7085 | * will occur. The workaround: | |
7086 | * 1. First PF driver which loads on a path will: | |
7087 | * a. After taking the chip out of reset, by using pretend, | |

7093 | * And for itself it will write '1' to | |
7094 | * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable | |
7095 | * dmae-operations (writing to pram for example.) | |
7096 | * note: can be done for only function 6,7 but cleaner this | |
7097 | * way. | |
7098 | * b. Write zero+valid to the entire ILT. | |
7099 | * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of | |
7100 | * VNIC3 (of that port). The range allocated will be the | |
7101 | * entire ILT. This is needed to prevent ILT range error. | |
7102 | * 2. Any PF driver load flow: | |
7103 | * a. ILT update with the physical addresses of the allocated | |
7104 | * logical pages. | |
7105 | * b. Wait 20msec. - note that this timeout is needed to make | |
7106 | * sure there are no requests in one of the PXP internal | |
7107 | * queues with "old" ILT addresses. | |
7108 | * c. PF enable in the PGLC. | |
7109 | * d. Clear the was_error of the PF in the PGLC. (could have | |
2de67439 | 7110 | * occurred while driver was down) |
619c5cb6 VZ |
7111 | * e. PF enable in the CFC (WEAK + STRONG) |
7112 | * f. Timers scan enable | |
7113 | * 3. PF driver unload flow: | |
7114 | * a. Clear the Timers scan_en. | |
7115 | * b. Polling for scan_on=0 for that PF. | |
7116 | * c. Clear the PF enable bit in the PXP. | |
7117 | * d. Clear the PF enable in the CFC (WEAK + STRONG) | |
7118 | * e. Write zero+valid to all ILT entries (The valid bit must | |
7119 | * stay set) | |
7120 | * f. If this is VNIC 3 of a port then also init | |
7121 | * first_timers_ilt_entry to zero and last_timers_ilt_entry | |
16a5fd92 | 7122 | * to the last entry in the ILT. |
619c5cb6 VZ |
7123 | * |
7124 | * Notes: | |
7125 | * Currently the PF error in the PGLC is non recoverable. | |
7126 | * In the future the there will be a recovery routine for this error. | |
7127 | * Currently attention is masked. | |
7128 | * Having an MCP lock on the load/unload process does not guarantee that | |
7129 | * there is no Timer disable during Func6/7 enable. This is because the | |
7130 | * Timers scan is currently being cleared by the MCP on FLR. | |
7131 | * Step 2.d can be done only for PF6/7 and the driver can also check if | |
7132 | * there is error before clearing it. But the flow above is simpler and | |
7133 | * more general. | |
7134 | * All ILT entries are written by zero+valid and not just PF6/7 | |
7135 | * ILT entries since in the future the ILT entries allocation for | |
7136 | * PF-s might be dynamic. | |
