* netxen: implement generic pcie semaphore functionsDhananjay Phadke2009-08-276-144/+71Star
| | | | | | | | | | | | Implement common function for locking/unlocking 8 hardware semaphores used for serializing access to shared resouces on a NIC board by different PCI functions. As by definition, callers of these semaphore API can be put to sleep till the semaphore is locked. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S.

* | RDS: Add a debug message suggesting to load transport modulesAndy Grover2009-08-241-0/+3
| | | | | | | | | | | | | | | | | | Now that RDS transports are no longer compiled-in to RDS core, there is now the possibility that they will not be loaded. This adds a helpful suggestion when rds_bind() fails to find a transport. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | RDS: Track transports via an array, not a listAndy Grover2009-08-245-10/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that transports can be loaded in arbitrary order, it is important for rds_trans_get_preferred() to look for them in a particular order, instead of walking the list until it finds a transport that works for a given address. Now, each transport registers for a specific transport slot, and these are ordered so that preferred transports come first, and then if they are not loaded, other transports are queried.

| | | | | | | | | | | | | | | | | | | | | | This code allows RDS to be tunneled over a TCP connection. RDMA operations are disabled when using TCP transport, but this frees RDS from the IB/RDMA stack dependency, and allows it to be used with standard Ethernet adapters, or in a VM.

| * | mwl8k: fix firmware command serialisationLennert Buytenhek2009-08-201-65/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current mwl8k_priv->fw_lock spinlock doesn't actually protect against multiple commands being submitted at once, as it is not kept held over the entire firmware command submission. And since waiting for command completion sleeps, we can't use a spinlock anyway. To fix mwl8k firmware command serialisation properly, we have the following requirements: - Some commands require that the packet transmit path is idle when the command is issued. (For simplicity, we'll just quiesce the transmit path for every command.) - There are certain sequences of commands that need to be issued to the hardware sequentially, with no other intervening commands. This leads to an implementation of a "firmware lock" as a mutex that can be taken recursively, and which is taken by both the low-level command submission function (mwl8k_post_cmd) as well as any users of that function that require issuing of an atomic sequence of commands, and quiesces the transmit path whenever it's taken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding and removing the DMA header that the mwl8k hardware requires on tx and provides on rx can never fail, since we are guaranteed to have enough headroom on the tx path to expand the packet, and we only ever shrink the packet on the rx path. (And on both paths we are guaranteed to be the only user of the skb we are handling.) This allows removing all of the skb clone handling in the tx and tx reclaim paths, and eliminates error checks in both the tx and rx paths, simplifying the code a bit more.
