Hi,


I have performed some tests with P4 at ELTE (experimental branch) and our P4 Paxos implementation (acceptor.p4 and coordinator.p4 are the two top files):


https://github.com/usi-systems/p4paxos/tree/master/p4src


I have encountered some warnings and an error during the make phase, the error messages are included in "MAKE_error.txt" attached file.


The error is due to a macro which is not yet implemented.


After removing the line that caused the error, I have been able to compile, to make and to run the two top files.


Now the problem is that, as soon as I send one or more packets to the network interface managed by the dpdk driver, the program terminates with no error message.


I have attached the dmesg log, which shows a segmentation fault error.


I also would like to know which is the role of the dpdk controller, which is required to run the applications and if, in our case, it is enough to provide a controller which simply forwards the packets (with no additional functionality).


I have tested our P4 Paxos implementation with both "dpdk_controller" and "dpdk_l2_l3_controller".


Thank you!

Pietro Bressana
