2018-01-25Merge "Integrate irq mode into PROX (support display and command line)"Deepak S1-1/+24
2018-01-24Fix extrapolation used in latency measurementsXavier Simonart1-4/+4
When doing latency measurements PROX takes into account the generation or reception of a bulk of packets. For instance, if PROX receives at time T 4 packets, it knows that the first packet was received by te NIC before T (the time to receive the other 3 packets, as they were received at maximum link speed). So the latency data is decreased by the minimum time to receive those 3 packets. For this PROX was using a default link speed of 10Gbps. This is wrong for 1Gbps and 40Gbps networks, and was causing for instance issues on 40 Gbps networks as extrapolating too much, resulting in either too low latencies or negative numbers (visible as very high latencies).

2018-01-16Integrate irq mode into PROX (support display and command line)Xavier Simonart1-1/+24
irq mode can be used to show how a core is interrupted by other tasks. This mode does not handle packets. It only loops reading tsc. When the difference between two consecutive calls to rdtsc() is high then it means the core was interrupted. This task implementes the display, so that we can see a histogram of interrupts as well as the maximum, per core. Command line is also supported, through "show irq buckets" (too show the intervals of each buckets, in micrcoseconds), and the stats command line (showing the number of items in each buckets and the max)..

2017-12-06Fix command parserXavier Simonart1-13/+12
Command parser could have been crashing if a wrong core/task was used in pkt_size command. For some other commands both an error and a warning were printed in case of errors. Change-Id: I6648bfca1b5bcde3c6393d49687ed84900326d49 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2017-11-15Add support for nop mode with l3 submodeXavier Simonart1-4/+4
The l3 submode was not supported in nop mode, as the nop mode uses some specific nop thread (and not generic). When L3 is specified, the nop mode must use the generic thread. In addition the l3 submode is implemented differently than other submodes. It is not supported through task_init structures (i.e. each task does not have to explicitely tell that it supports l3 submode). But this prevented to run both a nop with no submode and a nop with a l3 submode. Note that nop with l3 is usually not very useful - it handles arp (requests and response) but as nop, it does not swap IP addresses. So with a real switch, the packets transmitted will be received back... and l3 mode is usually mainly usefull when using a switch. However, there is at least one nop mode where l3 submode makes sense: when the nop does not transmit. In such cases, for instace used in conjunction with a gen l3, the nop receives all packets and forward the arp requests and responses to the master for handling.

2017-07-14Adding PROX(Packet pROcessing eXecution engine) VNF to sampleVNFDeepak S1-0/+2031
JIRA: SAMPLEVNF-55 PROX is a DPDK-based application implementing Telco use-cases such as a simplified BRAS/BNG, light-weight AFTR... It also allows configuring finer grained network functions like QoS, Routing, load-balancing... (We are moving PROX version v039 to sampleVNF https://01.org/intel-data-plane-performance-demonstrators/prox-overview) Change-Id: Ia3cb02cf0e49ac5596e922c197ff7e010293d033 Signed-off-by: Deepak S <deepak.s@linux.intel.com>
