6773 * This occurs when a different function (func2,3) is being marked
6774 * as "scan-off". Real-life scenario for example: if a driver is being
6775 * load-unloaded while func6,7 are down. This will cause the timer to access
6776 * the ilt, translate to a logical address and send a request to read/write.
6777 * Since the ilt for the function that is down is not valid, this will cause
6778 * a translation error which is unrecoverable.
6779 * The Workaround is intended to make sure that when this happens nothing fatal
6780 * will occur. The workaround:
6781 * 1. First PF driver which loads on a path will:
6782 * a. After taking the chip out of reset, by using pretend,
6783 * it will write "0" to the following registers of

6788 * And for itself it will write '1' to
6789 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
6790 * dmae-operations (writing to pram for example.)
6791 * note: can be done for only function 6,7 but cleaner this
6793 * b. Write zero+valid to the entire ILT.
6794 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
6795 * VNIC3 (of that port). The range allocated will be the
6796 * entire ILT. This is needed to prevent ILT range error.
6797 * 2. Any PF driver load flow:
6798 * a. ILT update with the physical addresses of the allocated
6800 * b. Wait 20msec. - note that this timeout is needed to make
6801 * sure there are no requests in one of the PXP internal
6802 * queues with "old" ILT addresses.
6803 * c. PF enable in the PGLC.
6804 * d. Clear the was_error of the PF in the PGLC. (could have
6805 * occurred while driver was down)
6806 * e. PF enable in the CFC (WEAK + STRONG)
6807 * f. Timers scan enable
6808 * 3. PF driver unload flow:
6809 * a. Clear the Timers scan_en.
6810 * b. Polling for scan_on=0 for that PF.
6811 * c. Clear the PF enable bit in the PXP.
6812 * d. Clear the PF enable in the CFC (WEAK + STRONG)
6813 * e. Write zero+valid to all ILT entries (The valid bit must
6815 * f. If this is VNIC 3 of a port then also init
6816 * first_timers_ilt_entry to zero and last_timers_ilt_entry
6817 * to the last entry in the ILT.
6820 * Currently the PF error in the PGLC is non recoverable.
6821 * In the future the there will be a recovery routine for this error.
6822 * Currently attention is masked.
6823 * Having an MCP lock on the load/unload process does not guarantee that
6824 * there is no Timer disable during Func6/7 enable. This is because the
6825 * Timers scan is currently being cleared by the MCP on FLR.
6826 * Step 2.d can be done only for PF6/7 and the driver can also check if
6827 * there is error before clearing it. But the flow above is simpler and
6829 * All ILT entries are written by zero+valid and not just PF6/7
6830 * ILT entries since in the future the ILT entries allocation for
6831 * PF-s might be dynamic.
