* Post a slowpath command.
|

*
|
|
* A slowpath command is used to propagate a configuration change through
|
|
* the controller in a controlled manner, allowing each STORM processor and
|
|
* other H/W blocks to phase in the change. The commands sent on the
|
|
* slowpath are referred to as ramrods. Depending on the ramrod used the
|
|
* completion of the ramrod will occur in different ways. Here's a
|
|
* breakdown of ramrods and how they complete:
|
|
*
|
|
* RAMROD_CMD_ID_ETH_PORT_SETUP
|
|
* Used to setup the leading connection on a port. Completes on the
|
|
* Receive Completion Queue (RCQ) of that port (typically fp[0]).
|
|
*
|
|
* RAMROD_CMD_ID_ETH_CLIENT_SETUP
|
|
* Used to setup an additional connection on a port. Completes on the
|
|
* RCQ of the multi-queue/RSS connection being initialized.
|
|
*
|
|
* RAMROD_CMD_ID_ETH_STAT_QUERY
|
|
* Used to force the storm processors to update the statistics database
|
|
* in host memory. This ramrod is send on the leading connection CID and
|
|
* completes as an index increment of the CSTORM on the default status
|
|
* block.
|
|
*
|
|
* RAMROD_CMD_ID_ETH_UPDATE
|
|
* Used to update the state of the leading connection, usually to udpate
|
|
* the RSS indirection table. Completes on the RCQ of the leading
|
|
* connection. (Not currently used under FreeBSD until OS support becomes
|
|
* available.)
|
|
*
|
|
* RAMROD_CMD_ID_ETH_HALT
|
|
* Used when tearing down a connection prior to driver unload. Completes
|
|
* on the RCQ of the multi-queue/RSS connection being torn down. Don't
|
|
* use this on the leading connection.
|
|
*
|
|
* RAMROD_CMD_ID_ETH_SET_MAC
|
|
* Sets the Unicast/Broadcast/Multicast used by the port. Completes on
|
|
* the RCQ of the leading connection.
|
|
*
|
|
* RAMROD_CMD_ID_ETH_CFC_DEL
|
|
* Used when tearing down a conneciton prior to driver unload. Completes
|
|
* on the RCQ of the leading connection (since the current connection
|
|
* has been completely removed from controller memory).
|
|
*
|
|
* RAMROD_CMD_ID_ETH_PORT_DEL
|
|
* Used to tear down the leading connection prior to driver unload,
|
|
* typically fp[0]. Completes as an index increment of the CSTORM on the
|
|
* default status block.
|
|
*
|
|
* RAMROD_CMD_ID_ETH_FORWARD_SETUP
|
|
* Used for connection offload. Completes on the RCQ of the multi-queue
|
|
* RSS connection that is being offloaded. (Not currently used under
|
|
* FreeBSD.)
|
|
*
|
|
* There can only be one command pending per function.
|
|
*
|
|
* Returns:
|
|
* 0 = Success, !0 = Failure.

|
|
* In E2 there is a bug in the timers block that can cause function 6 / 7
|
|
* (i.e. vnic3) to start even if it is marked as "scan-off".
|
|
* This occurs when a different function (func2,3) is being marked
|
|
* as "scan-off". Real-life scenario for example: if a driver is being
|
|
* load-unloaded while func6,7 are down. This will cause the timer to access
|
|
* the ilt, translate to a logical address and send a request to read/write.
|
|
* Since the ilt for the function that is down is not valid, this will cause
|
|
* a translation error which is unrecoverable.
|
|
* The Workaround is intended to make sure that when this happens nothing
|
|
* fatal will occur. The workaround:
|
|
* 1. First PF driver which loads on a path will:
|
|
* a. After taking the chip out of reset, by using pretend,
|
|
* it will write "0" to the following registers of
|
|
* the other vnics.
|
|
* REG_WR(pdev, PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER, 0);
|
|
* REG_WR(pdev, CFC_REG_WEAK_ENABLE_PF,0);
|
|
* REG_WR(pdev, CFC_REG_STRONG_ENABLE_PF,0);
|
|
* And for itself it will write '1' to
|
|
* PGLUE_B_REG_INTERNAL_PFID_ENABLE_MASTER to enable
|
|
* dmae-operations (writing to pram for example.)
|
|
* note: can be done for only function 6,7 but cleaner this
|
|
* way.
|
|
* b. Write zero+valid to the entire ILT.
|
|
* c. Init the first_timers_ilt_entry, last_timers_ilt_entry of
|
|
* VNIC3 (of that port). The range allocated will be the
|
|
* entire ILT. This is needed to prevent ILT range error.
|
|
* 2. Any PF driver load flow:
|
|
* a. ILT update with the physical addresses of the allocated
|
|
* logical pages.
|
|
* b. Wait 20msec. - note that this timeout is needed to make
|
|
* sure there are no requests in one of the PXP internal
|
|
* queues with "old" ILT addresses.
|
|
* c. PF enable in the PGLC.
|
|
* d. Clear the was_error of the PF in the PGLC. (could have
|
|
* occurred while driver was down)
|
|
* e. PF enable in the CFC (WEAK + STRONG)
|
|
* f. Timers scan enable
|
|
* 3. PF driver unload flow:
|
|
* a. Clear the Timers scan_en.
|
|
* b. Polling for scan_on=0 for that PF.
|
|
* c. Clear the PF enable bit in the PXP.
|
|
* d. Clear the PF enable in the CFC (WEAK + STRONG)
|
|
* e. Write zero+valid to all ILT entries (The valid bit must
|
|
* stay set)
|
|
* f. If this is VNIC 3 of a port then also init
|
|
* first_timers_ilt_entry to zero and last_timers_ilt_entry
|
|
* to the last entry in the ILT.
|
|
*
|
|
* Notes:
|
|
* Currently the PF error in the PGLC is non recoverable.
|
|
* In the future the there will be a recovery routine for this error.
|
|
* Currently attention is masked.
|
|
* Having an MCP lock on the load/unload process does not guarantee that
|
|
* there is no Timer disable during Func6/7 enable. This is because the
|
|
* Timers scan is currently being cleared by the MCP on FLR.
|
|
* Step 2.d can be done only for PF6/7 and the driver can also check if
|
|
* there is error before clearing it. But the flow above is simpler and
|
|
* more general.
|
|
* All ILT entries are written by zero+valid and not just PF6/7
|
|
* ILT entries since in the future the ILT entries allocation for
|
|
* PF-s might be dynamic.
