* IB/qib: Convert opcode counters to per-contextMike Marciniszyn2013-06-218-23/+284
| | | | | | | | | | | | | | | | | This fix changes the opcode relative counters for receive to per context. Profiling has shown that when mulitple contexts are being used there is a lot of cache activity associated with these counters. The code formerly kept these counters per port, but only provided the interface to read per HCA. This patch converts the read of counters to per HCA and adds the debugfs hooks to be able to read the file as a sequence of opcodes.

* IB/qib: Optimize CQ callbacksMike Marciniszyn2013-06-214-24/+76
| | | | | | | | | | | | | | | The current workqueue implemention has the following performance deficiencies on QDR HCAs: - The CQ call backs tend to run on the CPUs processing the receive queues - The single thread queue isn't optimal for multiple HCAs This patch adds a dedicated per HCA bound thread to process CQ callbacks.

* IB/qib: Add dual-rail NUMA awareness for PSM processesRamkrishna Vepa2013-06-211-49/+125
| | | | | | | | | | | | | | | | | | | | The driver currently selects a HCA based on the algorithm that PSM chooses, contexts within a HCA or across. The HCA can also be chosen by the user. Either way, this patch assigns a CPU on the NUMA node local to the selected HCA. This patch also tries to select the HCA closest to the NUMA node of the CPU assigned via taskset to PSM process. If this HCA is unusable then another unit is selected based on the algorithm that is currently enforced or selected by PSM - round robin context selection 'within' or 'across' HCA's. Fixed a bug wherein contexts are setup on the NUMA node on which the processes are opened (setup_ctxt()) and not on the NUMA node that the driver recommends the CPU on.

* IB/qib: Add optional NUMA affinityRamkrishna Vepa2013-06-213-9/+43
| | | | | | | | | | | | | | | | | | | This patch adds context relative numa affinity conditioned on the module parameter numa_aware. The qib_ctxtdata has an additional node_id member and qib_create_ctxtdata() has an addition node_id parameter. The allocations within the hdr queue and eager queue setup routines now take this additional member and adjust allocations as necesary. PSM will pass the either current numa node or the node closest to the HCA depending on numa_aware. Verbs will always use the node closest to the HCA.

* htb: refactor struct htb_sched fields for performanceEric Dumazet2013-06-191-86/+95
| | | | | | | | | | | | | | | | | | | | | htb_sched structures are big, and source of false sharing on SMP. Every time a packet is queued or dequeue, many cache lines must be touched because structures are not lay out properly. By carefully splitting htb_sched in two parts, and define sub structures to increase data locality, we can improve performance dramatically on SMP. New htb_prio structure can also be used in htb_class to increase data locality. I got 26 % performance increase on a 24 threads machine, with 200 concurrent netperf in TCP_RR mode, using a HTB hierarchy of 4 classes.

* tcp: introduce a per-route knob for quick ackCong Wang2013-06-193-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In previous discussions, I tried to find some reasonable heuristics for delayed ACK, however this seems not possible, according to Eric: "ACKS might also be delayed because of bidirectional traffic, and is more controlled by the application response time. TCP stack can not easily estimate it." "ACK can be incredibly useful to recover from losses in a short time. The vast majority of TCP sessions are small lived, and we send one ACK per received segment anyway at beginning or retransmits to let the sender smoothly increase its cwnd, so an auto-tuning facility wont help them that much." and according to David: "ACKs are the only information we have to detect loss. And, for the same reasons that TCP VEGAS is fundamentally broken, we cannot measure the pipe or some other receiver-side-visible piece of information to determine when it's "safe" to stretch ACK. And even if it's "safe", we should not do it so that losses are accurately detected and we don't spuriously retransmit. The only way to know when the bandwidth increases is to "test" it, by sending more and more packets until drops happen. That's why all successful congestion control algorithms must operate on explicited tested pieces of information. Similarly, it's not really possible to universally know if it's safe to stretch ACK or not." It still makes sense to enable or disable quick ack mode like what TCP_QUICK_ACK does. Similar to TCP_QUICK_ACK option, but for people who can't modify the source code and still wants to control TCP delayed ACK behavior. As David suggested, this should belong to per-path scope, since different pathes may want different behaviors.

* net: sock: adapt SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUFDaniel Borkmann2013-06-191-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The current situation is that SOCK_MIN_RCVBUF is 2048 + sizeof(struct sk_buff)) while SOCK_MIN_SNDBUF is 2048. Since in both cases, skb->truesize is used for sk_{r,w}mem_alloc accounting, we should have both sizes adjusted via defining a TCP_SKB_MIN_TRUESIZE. Further, as Eric Dumazet points out, the minimal skb truesize in transmit path is SKB_TRUESIZE(2048) after commit f07d960df33c5 ("tcp: avoid frag allocation for small frames"), and tcp_sendmsg() tries to limit skb size to half the congestion window, meaning we try to build two skbs at minimum. Thus, having SOCK_MIN_SNDBUF as 2048 can hit a small regression for some applications setting to low SO_SNDBUF / SO_RCVBUF. Note that we define a TCP_SKB_MIN_TRUESIZE, because SKB_TRUESIZE(2048) adds SKB_DATA_ALIGN(sizeof(struct skb_shared_info)), but in case of TCP skbs, the skb_shared_info is part of the 2048 bytes allocation for skb->head. The minor adaption in sk_stream_moderate_sndbuf() is to silence a warning by using a typed max macro, as similarly done in SOCK_MIN_RCVBUF occurences, that would appear otherwise.
