887 * Post a slowpath command.
889 * A slowpath command is used to propogate a configuration change through
890 * the controller in a controlled manner, allowing each STORM processor and
891 * other H/W blocks to phase in the change. The commands sent on the
892 * slowpath are referred to as ramrods. Depending on the ramrod used the
893 * completion of the ramrod will occur in different ways. Here's a
894 * breakdown of ramrods and how they complete:
896 * RAMROD_CMD_ID_ETH_PORT_SETUP
897 * Used to setup the leading connection on a port. Completes on the
898 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
900 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
901 * Used to setup an additional connection on a port. Completes on the
902 * RCQ of the multi-queue/RSS connection being initialized.
904 * RAMROD_CMD_ID_ETH_STAT_QUERY
905 * Used to force the storm processors to update the statistics database
906 * in host memory. This ramrod is send on the leading connection CID and
907 * completes as an index increment of the CSTORM on the default status
910 * RAMROD_CMD_ID_ETH_UPDATE
911 * Used to update the state of the leading connection, usually to udpate
912 * the RSS indirection table. Completes on the RCQ of the leading
913 * connection. (Not currently used under FreeBSD until OS support becomes
916 * RAMROD_CMD_ID_ETH_HALT
917 * Used when tearing down a connection prior to driver unload. Completes
918 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
919 * use this on the leading connection.
921 * RAMROD_CMD_ID_ETH_SET_MAC
922 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
923 * the RCQ of the leading connection.
925 * RAMROD_CMD_ID_ETH_CFC_DEL
926 * Used when tearing down a conneciton prior to driver unload. Completes
927 * on the RCQ of the leading connection (since the current connection
928 * has been completely removed from controller memory).
930 * RAMROD_CMD_ID_ETH_PORT_DEL
931 * Used to tear down the leading connection prior to driver unload,
932 * typically fp[0]. Completes as an index increment of the CSTORM on the
933 * default status block.
935 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
936 * Used for connection offload. Completes on the RCQ of the multi-queue
937 * RSS connection that is being offloaded. (Not currently used under
940 * There can only be one command pending per function.

10141 * In E2 there is a bug in the timers block that can cause function 6 / 7
10142 * (i.e. vnic3) to start even if it is marked as "scan-off".
10143 * This occurs when a different function (func2,3) is being marked
10144 * as "scan-off". Real-life scenario for example: if a driver is being
10145 * load-unloaded while func6,7 are down. This will cause the timer to access
10146 * the ilt, translate to a logical address and send a request to read/write.
10147 * Since the ilt for the function that is down is not valid, this will cause
10148 * a translation error which is unrecoverable.
10149 * The Workaround is intended to make sure that when this happens nothing
10150 * fatal will occur. The workaround:
10151 * 1. First PF driver which loads on a path will:
10152 * a. After taking the chip out of reset, by using pretend,
10153 * it will write "0" to the following registers of
10155 * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
10156 * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
10157 * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
10158 * And for itself it will write '1' to
10159 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
10160 * dmae-operations (writing to pram for example.)
10161 * note: can be done for only function 6,7 but cleaner this
10163 * b. Write zero+valid to the entire ILT.
10164 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
10165 * VNIC3 (of that port). The range allocated will be the
10166 * entire ILT. This is needed to prevent ILT range error.
10167 * 2. Any PF driver load flow:
10168 * a. ILT update with the physical addresses of the allocated
10170 * b. Wait 20msec. - note that this timeout is needed to make
10171 * sure there are no requests in one of the PXP internal
10172 * queues with "old" ILT addresses.
10173 * c. PF enable in the PGLC.
10174 * d. Clear the was_error of the PF in the PGLC. (could have
10175 * occurred while driver was down)
10176 * e. PF enable in the CFC (WEAK + STRONG)
10177 * f. Timers scan enable
10178 * 3. PF driver unload flow:
10179 * a. Clear the Timers scan_en.
10180 * b. Polling for scan_on=0 for that PF.
10181 * c. Clear the PF enable bit in the PXP.
10182 * d. Clear the PF enable in the CFC (WEAK + STRONG)
10183 * e. Write zero+valid to all ILT entries (The valid bit must
10185 * f. If this is VNIC 3 of a port then also init
10186 * first_timers_ilt_entry to zero and last_timers_ilt_entry
10187 * to the last enrty in the ILT.
10190 * Currently the PF error in the PGLC is non recoverable.
10191 * In the future the there will be a recovery routine for this error.
10192 * Currently attention is masked.
10193 * Having an MCP lock on the load/unload process does not guarantee that
10194 * there is no Timer disable during Func6/7 enable. This is because the
10195 * Timers scan is currently being cleared by the MCP on FLR.
10196 * Step 2.d can be done only for PF6/7 and the driver can also check if
10197 * there is error before clearing it. But the flow above is simpler and
10199 * All ILT entries are written by zero+valid and not just PF6/7
10200 * ILT entries since in the future the ILT entries allocation for
10201 * PF-s might be dynamic.
