2013-03-17tcp: Remove TCPCTChristoph Paasch1-1/+1
TCPCT uses option-number 253, reserved for experimental use and should not be used in production environments. Further, TCPCT does not fully implement RFC 6013. As a nice side-effect, removing TCPCT increases TCP's performance for very short flows: Doing an apache-benchmark with -c 100 -n 100000, sending HTTP-requests for files of 1KB size. before this patch: average (among 7 runs) of 20845.5 Requests/Second after: average (among 7 runs) of 21403.6 Requests/Second Signed-off-by: Christoph Paasch <christoph.paasch@uclouvain.be> Signed-off-by: David S.

2013-03-14RDMA/cxgb4: Fix onchip queue support for T5Vipul Pandya1-8/+5
T5 adapter does not support onchip queue memory. Present logic fails to allocate QP for T5 and returns an error. Also, if module parameter ocqp_support is zero then we are unable to allocate QP which should not be the case. Ideally if ocqp_support parameter is 0 or onchip queue support is disable then host QP should be allocated before returning an error.

2013-03-14RDMA/cxgb4: Use DSGLs for fastreg and adapter memory writes for T5.Vipul Pandya4-36/+182
It enables direct DMA by HW to memory region PBL arrays and fast register PBL arrays from host memory, vs the T4 way of passing these arrays in the WR itself. The result is lower latency for memory registration, and larger PBL array support for fast register operations. This patch also updates ULP_TX_MEM_WRITE command fields for T5. Ordering bit of ULP_TX_MEM_WRITE is at bit position 22 in T5 and at 23 in T4. Signed-off-by: Vipul Pandya <vipul@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-02-21IB/core: Add "type 2" memory windows supportShani Michaeli2-2/+5
This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Shani Michaeli <shanim@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

2013-02-14RDMA/cxgb4: "cookie" can stay in host endiannessPaul Bolle1-2/+2
Work requests are passed between the host and the firmware with a "cookie". This cookie is swapped to big-endian when passed to the firmware and back to host endianness on return. This swapping seems to be implemented incorrectly. Moreover, the byte swapping triggers GCC warnings on 32 bit: drivers/infiniband/hw/cxgb4/cm.c: In function ‘passive_ofld_conn_reply’: drivers/infiniband/hw/cxgb4/cm.c:2803:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] drivers/infiniband/hw/cxgb4/cm.c: In function ‘send_fw_pass_open_req’: drivers/infiniband/hw/cxgb4/cm.c:2941:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] [...] But byte swapping isn't needed as the firmware doesn't actually touch the cookie.
