5953 * Since the ilt for the function that is down is not valid, this will cause
5954 * a translation error which is unrecoverable.
5955 * The Workaround is intended to make sure that when this happens nothing fatal
5956 * will occur. The workaround:
5957 * 1. First PF driver which loads on a path will:
5958 * a. After taking the chip out of reset, by using pretend,
5959 * it will write "0" to the following registers of

5964 * And for itself it will write '1' to
5965 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
5966 * dmae-operations (writing to pram for example.)
5967 * note: can be done for only function 6,7 but cleaner this
5968 * way.
5969 * b. Write zero+valid to the entire ILT.
5970 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
5971 * VNIC3 (of that port). The range allocated will be the
5972 * entire ILT. This is needed to prevent ILT range error.
5973 * 2. Any PF driver load flow:
5974 * a. ILT update with the physical addresses of the allocated
5975 * logical pages.
5976 * b. Wait 20msec. - note that this timeout is needed to make
5977 * sure there are no requests in one of the PXP internal
5978 * queues with "old" ILT addresses.
5979 * c. PF enable in the PGLC.
5980 * d. Clear the was_error of the PF in the PGLC. (could have
5981 * occured while driver was down)
5982 * e. PF enable in the CFC (WEAK + STRONG)
5983 * f. Timers scan enable
5984 * 3. PF driver unload flow:
5985 * a. Clear the Timers scan_en.
5986 * b. Polling for scan_on=0 for that PF.
5987 * c. Clear the PF enable bit in the PXP.
5988 * d. Clear the PF enable in the CFC (WEAK + STRONG)
5989 * e. Write zero+valid to all ILT entries (The valid bit must
5990 * stay set)
5991 * f. If this is VNIC 3 of a port then also init
5992 * first_timers_ilt_entry to zero and last_timers_ilt_entry
5993 * to the last enrty in the ILT.
5994 *
5995 * Notes:
5996 * Currently the PF error in the PGLC is non recoverable.
5997 * In the future the there will be a recovery routine for this error.
5998 * Currently attention is masked.
5999 * Having an MCP lock on the load/unload process does not guarantee that
6000 * there is no Timer disable during Func6/7 enable. This is because the
6001 * Timers scan is currently being cleared by the MCP on FLR.
6002 * Step 2.d can be done only for PF6/7 and the driver can also check if
6003 * there is error before clearing it. But the flow above is simpler and
6004 * more general.
6005 * All ILT entries are written by zero+valid and not just PF6/7
6006 * ILT entries since in the future the ILT entries allocation for
6007 * PF-s might be dynamic.
