7123 * load-unloaded while func6,7 are down. This will cause the timer to access
7124 * the ilt, translate to a logical address and send a request to read/write.
7125 * Since the ilt for the function that is down is not valid, this will cause
7126 * a translation error which is unrecoverable.
7127 * The Workaround is intended to make sure that when this happens nothing fatal
7128 * will occur. The workaround:
7129 * 1. First PF driver which loads on a path will:
7130 * a. After taking the chip out of reset, by using pretend,
7131 * it will write "0" to the following registers of

7136 * And for itself it will write '1' to
7137 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
7138 * dmae-operations (writing to pram for example.)
7139 * note: can be done for only function 6,7 but cleaner this
7140 * way.
7141 * b. Write zero+valid to the entire ILT.
7142 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
7143 * VNIC3 (of that port). The range allocated will be the
7144 * entire ILT. This is needed to prevent ILT range error.
7145 * 2. Any PF driver load flow:
7146 * a. ILT update with the physical addresses of the allocated
7147 * logical pages.
7148 * b. Wait 20msec. - note that this timeout is needed to make
7149 * sure there are no requests in one of the PXP internal
7150 * queues with "old" ILT addresses.
7151 * c. PF enable in the PGLC.
7152 * d. Clear the was_error of the PF in the PGLC. (could have
7153 * occurred while driver was down)
7154 * e. PF enable in the CFC (WEAK + STRONG)
7155 * f. Timers scan enable
7156 * 3. PF driver unload flow:
7157 * a. Clear the Timers scan_en.
7158 * b. Polling for scan_on=0 for that PF.
7159 * c. Clear the PF enable bit in the PXP.
7160 * d. Clear the PF enable in the CFC (WEAK + STRONG)
7161 * e. Write zero+valid to all ILT entries (The valid bit must
7162 * stay set)
7163 * f. If this is VNIC 3 of a port then also init
7164 * first_timers_ilt_entry to zero and last_timers_ilt_entry
7165 * to the last entry in the ILT.
7166 *
7167 * Notes:
7168 * Currently the PF error in the PGLC is non recoverable.
7169 * In the future the there will be a recovery routine for this error.
7170 * Currently attention is masked.
7171 * Having an MCP lock on the load/unload process does not guarantee that
7172 * there is no Timer disable during Func6/7 enable. This is because the
7173 * Timers scan is currently being cleared by the MCP on FLR.
7174 * Step 2.d can be done only for PF6/7 and the driver can also check if
7175 * there is error before clearing it. But the flow above is simpler and
7176 * more general.
7177 * All ILT entries are written by zero+valid and not just PF6/7
7178 * ILT entries since in the future the ILT entries allocation for
7179 * PF-s might be dynamic.
