06e7434d6c Solved some state problems. This commit also solves #154, which was caused by a non-terminated thread. (This thread will be removed in a later commit anyway 2018-07-07 15:34:07 +02:00

836adee4d6 Node is able to clean everything up and reconnect. Node can abort if it is in STARTED and in CONNECTED state 2018-07-07 14:36:23 +02:00
Dennis Potter
80da4801e1 Source and target successfully connect and node changes status from STATE_STARTED to STATE_CONNECTED in this commit. Next step will be to fix ib_stop and ib_disconnect to make the target able to accept new connections. 2018-07-07 13:08:08 +02:00

e2061e58fc Events are now monitored in a separate thread. The segmentation faults we saw earlier were caused because we exited ib_start before we created a protection domain, which is used by memory_allocation 2018-07-07 12:49:22 +02:00
Dennis Potter
2bf122991c Started to convert the RDMA_CM_EVENT loop to a separate thread and added a new state to the node. This commit is still broken 2018-07-05 18:26:32 +02:00

a825009457 Removed bugs with regard to the zero-copy implementation. This commit is able to send -r 5000 -l 50000 with villas pipe. With a higher -r, the source throws errors that there aren't any receive WRs, so probably pipe doesn't fill up the WRs fast enough 2018-07-03 17:39:06 +02:00
45b121d884 infiniband: do not build memory allocator if node is not acticated 2018-07-02 16:05:05 +02:00
Dennis Potter
669d75a666 Basic implementation of zero-copying is done. The is still a problem with rread = hook_read_list. It doesn't return anything after the fourth read 2018-07-02 16:03:16 +02:00
bb70be0b2c memory: refactored memory subsystem 2018-07-02 15:57:56 +02:00

c055010be1 ib_write() now takes data directly from the super pool instead of copying it. ib_read() still copies data and the code needs cleanup after zero-copy is implemented 2018-07-01 12:56:03 +02:00

95393eeb35 Forgot to acknowledge events which caused the rdma_cm_id to block. 2018-06-28 14:43:08 +02:00
Dennis Potter
5598f93582 Implemented disconnect function on source and target side. The cleanup function doesn't go through completely yet, probably because rdma_destroy_id blocks because not everything in the rdma_cm_id is destroyed yet. 2018-06-28 12:46:16 +02:00
Dennis Potter
1df18da3f2 Added Work Completion threads. Send Completion thread checks for errors, Receive Completion Queue is still empty. 2018-06-27 17:01:47 +02:00

9e5836001d Node is able to send messages. A lot is hardcoded and this was only meant to be a first setup of a working node. 2018-06-27 10:37:46 +02:00

4fef5d67e5 Memory is registrated succesfully. Created framework to send data. At this moment, the receiver doesn't prepare Receive Work Requests. This is the first thing to fix after this commit 2018-06-25 18:21:44 +02:00

077355d8ba Started to implement memory managemen and registration. Not yet working and in an early stage. Still some debugging and testing printfs 2018-06-24 13:02:04 +02:00

a0f0410e73 This commit should be able to create a connection between two nodes.
This commit isn't checked for bugs and no memory management is done.
Furthermore, no poll threads are implemented.

fe302f9649 comedi: implement ADC and DAC directions, only DAC tested
The write / DAC direction has been tested with two output signals, see
etc/comedi.conf for reference. For now, the buffer size may not be
(considerably) smaller than 32kB, Comedi stops working for unknown
reasons. To compensate for the latency (always approx. one buffer size)
if only small sample rates are required, configure the path for
upsampling (sample-and-hold via rate parameter) at the same rate as
the out direction of the comedi node.
