- * 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
- * occurred 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 entry 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.
