2342 * A slowpath command is used to propogate a configuration change through

2344 * other H/W blocks to phase in the change. The commands sent on the
2345 * slowpath are referred to as ramrods. Depending on the ramrod used the
2346 * completion of the ramrod will occur in different ways. Here's a
2347 * breakdown of ramrods and how they complete:
2349 * RAMROD_CMD_ID_ETH_PORT_SETUP
2350 * Used to setup the leading connection on a port. Completes on the
2351 * Receive Completion Queue (RCQ) of that port (typically fp[0]).
2353 * RAMROD_CMD_ID_ETH_CLIENT_SETUP
2354 * Used to setup an additional connection on a port. Completes on the
2355 * RCQ of the multi-queue/RSS connection being initialized.
2357 * RAMROD_CMD_ID_ETH_STAT_QUERY
2358 * Used to force the storm processors to update the statistics database
2359 * in host memory. This ramrod is send on the leading connection CID and
2360 * completes as an index increment of the CSTORM on the default status
2363 * RAMROD_CMD_ID_ETH_UPDATE
2364 * Used to update the state of the leading connection, usually to udpate
2365 * the RSS indirection table. Completes on the RCQ of the leading
2366 * connection. (Not currently used under FreeBSD until OS support becomes
2369 * RAMROD_CMD_ID_ETH_HALT
2370 * Used when tearing down a connection prior to driver unload. Completes
2371 * on the RCQ of the multi-queue/RSS connection being torn down. Don't
2372 * use this on the leading connection.
2374 * RAMROD_CMD_ID_ETH_SET_MAC
2375 * Sets the Unicast/Broadcast/Multicast used by the port. Completes on
2376 * the RCQ of the leading connection.
2378 * RAMROD_CMD_ID_ETH_CFC_DEL
2379 * Used when tearing down a conneciton prior to driver unload. Completes
2380 * on the RCQ of the leading connection (since the current connection
2381 * has been completely removed from controller memory).
2383 * RAMROD_CMD_ID_ETH_PORT_DEL
2384 * Used to tear down the leading connection prior to driver unload,
2385 * typically fp[0]. Completes as an index increment of the CSTORM on the
2386 * default status block.
2388 * RAMROD_CMD_ID_ETH_FORWARD_SETUP
2389 * Used for connection offload. Completes on the RCQ of the multi-queue
2390 * RSS connection that is being offloaded. (Not currently used under
2393 * There can only be one command pending per function.

17336 * In E2 there is a bug in the timers block that can cause function 6 / 7
17337 * (i.e. vnic3) to start even if it is marked as "scan-off".
17338 * This occurs when a different function (func2,3) is being marked
17339 * as "scan-off". Real-life scenario for example: if a driver is being
17340 * load-unloaded while func6,7 are down. This will cause the timer to access
17341 * the ilt, translate to a logical address and send a request to read/write.
17342 * Since the ilt for the function that is down is not valid, this will cause
17343 * a translation error which is unrecoverable.
17344 * The Workaround is intended to make sure that when this happens nothing
17345 * fatal will occur. The workaround:
17346 * 1. First PF driver which loads on a path will:
17347 * a. After taking the chip out of reset, by using pretend,
17348 * it will write "0" to the following registers of
17350 * REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
17351 * REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
17352 * REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
17353 * And for itself it will write '1' to
17354 * PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
17355 * dmae-operations (writing to pram for example.)
17356 * note: can be done for only function 6,7 but cleaner this
17358 * b. Write zero+valid to the entire ILT.
17359 * c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
17360 * VNIC3 (of that port). The range allocated will be the
17361 * entire ILT. This is needed to prevent ILT range error.
17362 * 2. Any PF driver load flow:
17363 * a. ILT update with the physical addresses of the allocated
17365 * b. Wait 20msec. - note that this timeout is needed to make
17366 * sure there are no requests in one of the PXP internal
17367 * queues with "old" ILT addresses.
17368 * c. PF enable in the PGLC.
17369 * d. Clear the was_error of the PF in the PGLC. (could have
17370 * occurred while driver was down)
17371 * e. PF enable in the CFC (WEAK + STRONG)
17372 * f. Timers scan enable
17373 * 3. PF driver unload flow:
17374 * a. Clear the Timers scan_en.
17375 * b. Polling for scan_on=0 for that PF.
17376 * c. Clear the PF enable bit in the PXP.
17377 * d. Clear the PF enable in the CFC (WEAK + STRONG)
17378 * e. Write zero+valid to all ILT entries (The valid bit must
17380 * f. If this is VNIC 3 of a port then also init
17381 * first_timers_ilt_entry to zero and last_timers_ilt_entry
17382 * to the last enrty in the ILT.
17385 * Currently the PF error in the PGLC is non recoverable.
17386 * In the future the there will be a recovery routine for this error.
17387 * Currently attention is masked.
17388 * Having an MCP lock on the load/unload process does not guarantee that
17389 * there is no Timer disable during Func6/7 enable. This is because the
17390 * Timers scan is currently being cleared by the MCP on FLR.
17391 * Step 2.d can be done only for PF6/7 and the driver can also check if
17392 * there is error before clearing it. But the flow above is simpler and
17394 * All ILT entries are written by zero+valid and not just PF6/7
17395 * ILT entries since in the future the ILT entries allocation for
17396 * PF-s might be dynamic.
