6135 * This occurs when a different function (func2,3) is being marked
6136 * as "scan-off". Real-life scenario for example: if a driver is being
6137 * load-unloaded while func6,7 are down. This will cause the timer to access
6138 * the ilt, translate to a logical address and send a request to read/write.
6139 * Since the ilt for the function that is down is not valid, this will cause
6140 * a translation error which is unrecoverable.
6141 * The Workaround is intended to make sure that when this happens nothing fatal
6142 * will occur. The workaround:
6143 * 1. First PF driver which loads on a path will:
6144 * a. After taking the chip out of reset, by using pretend,
6145 * it will write "0" to the following registers of
6146 * the other vnics.
6147 * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
6148 * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
6149 * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
6150 * And for itself it will write '1' to
6151 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
6152 * dmae-operations (writing to pram for example.)
6153 * note: can be done for only function 6,7 but cleaner this
6154 * way.
6155 * b. Write zero+valid to the entire ILT.
6156 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6157 * VNIC3 (of that port). The range allocated will be the
6158 * entire ILT. This is needed to prevent ILT range error.
6159 * 2. Any PF driver load flow:
6160 * a. ILT update with the physical addresses of the allocated
6161 * logical pages.
6162 * b. Wait 20msec. - note that this timeout is needed to make
6163 * sure there are no requests in one of the PXP internal
6164 * queues with "old" ILT addresses.
6165 * c. PF enable in the PGLC.
6166 * d. Clear the was_error of the PF in the PGLC. (could have
6167 * occured while driver was down)
6168 * e. PF enable in the CFC (WEAK + STRONG)
6169 * f. Timers scan enable
6170 * 3. PF driver unload flow:
6171 * a. Clear the Timers scan_en.
6172 * b. Polling for scan_on=0 for that PF.
6173 * c. Clear the PF enable bit in the PXP.
6174 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6175 * e. Write zero+valid to all ILT entries (The valid bit must
6176 * stay set)
6177 * f. If this is VNIC 3 of a port then also init
6178 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6179 * to the last enrty in the ILT.
6180 *
6181 * Notes:
6182 * Currently the PF error in the PGLC is non recoverable.
6183 * In the future the there will be a recovery routine for this error.
6184 * Currently attention is masked.
6185 * Having an MCP lock on the load/unload process does not guarantee that
6186 * there is no Timer disable during Func6/7 enable. This is because the
6187 * Timers scan is currently being cleared by the MCP on FLR.
6188 * Step 2.d can be done only for PF6/7 and the driver can also check if
6189 * there is error before clearing it. But the flow above is simpler and
6190 * more general.
6191 * All ILT entries are written by zero+valid and not just PF6/7
6192 * ILT entries since in the future the ILT entries allocation for
6193 * PF-s might be dynamic.
