| * IB/hfi1: Allow for non-double word multiple message sizes for user SDMAIra Weiny2016-08-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver pads non-double word multiple message sizes but it doesn't account for this padding when the packet length is calculated. Also, the data length is miscalculated for message sizes less than 4 bytes due to the bit representation in LRH. And there's a check for non-double word multiple message sizes that prevents these messages from being sent. This patch fixes length miscalculations and enables the functionality to send non-double word multiple message sizes.

It also implements the packet IO layer. On the other hand ib_rxe registers to the Linux netdev stack as a udp encapsulating protocol, in that case RDMA, for sending and receiving packets over any Ethernet device. This yields a RDMA transport over the UDP/Ethernet network layer forming a RoCEv2 compatible device. The configuration procedure of the Soft RoCE drivers requires binding to any existing Ethernet network device. This is done with /sys interface. A userspace Soft RoCE library (librxe) provides user applications the ability to run with Soft RoCE devices. The use of rxe verbs ins user space requires the inclusion of librxe as a device specifics plug-in to libibverbs. librxe is packaged separately.

| * | IB/core: Support for CMA multicast join flagsAlex Vesker2016-08-031-1/+8
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added UCMA and CMA support for multicast join flags. Flags are passed using UCMA CM join command previously reserved fields. Currently supporting two join flags indicating two different multicast JoinStates: 1. Full Member: The initiator creates the Multicast group(MCG) if it wasn't previously created, can send Multicast messages to the group and receive messages from the MCG. 2. Send Only Full Member: The initiator creates the Multicast group(MCG) if it wasn't previously created, can send Multicast messages to the group but doesn't receive any messages from the MCG. IB: Send Only Full Member requires a query of ClassPortInfo to determine if SM/SA supports this option. If SM/SA doesn't support Send-Only there will be no join request sent and an error will be returned. ETH: When Send Only Full Member is requested no IGMP join will be sent.

Also remove the striping capability that is dependent upon the user choosing the multi-purpose cdev. It is now up to user space to determine how to stripe contexts.

* IB/core: Add timestamp_mask and hca_core_clock to query_deviceMatan Barak2015-06-121-0/+2
| | | | | | | | | | | | | | | | | In order to expose timestamp we need to expose two new attributes in query_device to be used for CQ completion time-stamping: timestamp_mask - how many bits are valid in the timestamp, where timestamp values could be 64bits the most. hca_core_clock - timestamp is given in HW cycles, the frequency in KHZ units of the HCA, necessary in order to convert cycles to seconds. This is added both to ib_query_device and its respective uverbs counterpart.

* IB/core: Add on demand paging caps to ib_uverbs_ex_query_deviceHaggai Eran2015-02-181-0/+11
| | | | | | | | | | | | | | | | | Add on-demand paging capabilities reporting to the extended query device verb. Yann Droneaud writes: Note: as offsetof() is used to retrieve the size of the lower chunk of the response, beware that it only works if the upper chunk is right after, without any implicit padding. And, as the size of the latter chunk is added to the base size, implicit padding at the end of the structure is not taken in account. Both point must be taken in account when extending the uverbs functionalities.

* IB/core: Add support for extended query device capsEli Cohen2015-02-181-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add extensible query device capabilities verb to allow adding new features. ib_uverbs_ex_query_device is added and copy_query_dev_fields is used to copy capability fields to be used by both ib_uverbs_query_device and ib_uverbs_ex_query_device. Following the discussion about this patch [1], the code now validates the command's comp_mask is zero, returning -EINVAL for unknown values, in order to allow extending the verb in the future. The verb also checks the user-space provided response buffer size and only fills in capabilities that will fit in the buffer. In attempt to follow the spirit of presentation [2] by Tzahi Oved that was presented during OpenFabrics Alliance International Developer Workshop 2013, the comp_mask bits will only describe which fields are valid. Furthermore, fields that can simply be cleared when they are not supported, do not require a comp_mask bit at all. The verb returns a response_length field containing the actual number of bytes written by the kernel, so that a newer version running on an older kernel can tell which fields were actually returned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While commit 7e36ef8205ff ("IB/core: Temporarily disable ex_query_device uverb") is correct as it makes the extended QUERY_DEVICE uverb (which came as part of commit 5a77abf9a97a ("IB/core: Add support for extended query device caps") and commit 860f10a799c8 ("IB/core: Add flags for on demand paging support")) not available to userspace, it doesn't address the initial issue regarding ib_copy_to_udata() [1][2]. Additionally, further discussions around this new uverb seems to conclude it would require a different data structure than the one currently described in <rdma/ib_user_verbs.h> [3]. Both of these issues require a revert of the changes, so this patch partially reverts commit 8cdd312cfed7 ("IB/mlx5: Implement the ODP capability query verb") and commit 860f10a799c8 ("IB/core: Add flags for on demand paging support") and fully reverts commit 5a77abf9a97a ("IB/core: Add support for extended query device caps").
