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 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.
