2018-03-05Fix minimum latencyXavier Simonart1-5/+11
Revert back part of commit 9fa316261d7d9 The function abs_diff was erroneously changed to diff_or_zero. This function was supposed to measure the difference between rx and tx time; when rx time overflowed and tx time not yet (i.e. rx time ~= 0 and tx_time ~=UINT32_MAX, this function added UINT32_MAX to rx_time. The name of the function was confusing and caused the previous commit. Net effect of previous commit was that every four seconds the minimum latency was 0 This commit reverse back to the original behavior, with a function name diff_time.

2018-02-27Fix potential crash if link speed is nullXavier Simonart2-2/+2
Link_speed could be null when prox started with the ports down. This was potentially causing a crash. Another task will need to update link speed when the port come up. Failing to do this results in less accurate latencies (no extrapolation) Change-Id: I597b68e30117e6edb9ccb4732c2acedd5eb8ac80 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>

2018-02-21Fixed the calculation of dropped packets and other changesLuc Provoost11-93/+142
* Calculation of aboslute and relative dropped packets was wrong and is now fixed. * ./createrapid.py has now an extra option to select custom availability zones for the different VMs. * Fixed a typo to create the flavor: hw:cpu_thread_policy * The generator config files have now the packet id & signature fields. See PROX for more details on this. * ./runrapid has now a new option --configonly. Default is False. If set to True, all configuration files will be copied to the VMS, but the tests are not started. This allows you to go to the VMs and manually start PROX. * In addition to the average latency, maximum latency is now also displayed.

2018-02-15Add support for comments in configuration variablesXavier Simonart3-9/+15
This feature will enable the possibility to have many cores configured in a prox config file, and enable/disable them through variables. For instance, a [core $var1] section in a config file will result in [core 1] if $var1 = 1; the whole section and section content will be ignored if $var1=# Before this implementation, [#core 1] or [core #] was already treated as a commented out section (the whole section was commented). But there was no way to define a variable $var = # to comment a section through a variable. Note that in today's implementation any non numerical (except s, h, t, -) characteter in the [core] section header (and not only #) will cause the section to be ignored. It would probably be better to consider # (as maybe N/A and none) as comments, and everything else as error. This is however not supported by the change request.

2018-02-12Zero packet loss testing has been added.Luc Provoost12-72/+277
Using l2 testing, where no ARP messages are being used, you can now run a zero packet loss test. The binary search will continue to find the speed where absolutely no packets have been lost during the test. On top of that, the output has been reformatted to also show the absolute and relative packet loss. The *.test files have now 2 new parameters: drop_rate_treshold and accuracy. When drop_rate_treshold is set to 0, this test will conclude successfull when no packet has been lost whatsoever. If this is set to any other number, the test will be successfull when the relative packet loss is lower than drop_rate_treshold. The new accuray parameter defines when the binary search will stop: when the relative difference between the min and max of the search window is lower than accuracy. The irq testing is slightly modified to print the total number of interrupts in a certain time bucket, not only as the number per second, but when there is no interrupt whatsowever, we print '0' in stead of '0.0' Change-Id: I8fafded0a225cbe1ba7ac61cd28e94d72099e4a0 Signed-off-by: Luc Provoost <luc.provoost@intel.com>

2018-01-24Fix extrapolation used in latency measurementsXavier Simonart3-11/+48
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 Simonart15-61/+556
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)..

When doing latency measurements the generator can add a 32 bits signature in the packet at a specific location, so that the receiver only uses the packets generated by the generator and ignores packets generated for instance by a switch The is particuly important for latency measurements as we use data in the packets as timestamps, and packets generated elsewhere would result in random latency for those packets.

2018-01-08Fix stacking of rx receive functionsXavier Simonart2-10/+11
PROX can stack different RX functions, so that they are executed after each other. This feature is for instance used to dump packets or to print distribution of receive packets, without influencing the performance of the rx functions when no dump or print is needed. The previous implementation was wrong and causing some of the stacked functions not to be executed. This was causing for instance issues in latency measurement after enabling dumping packets.

2018-01-04Add config option to use port mac as src mac in l2fwd and swapXavier Simonart3-27/+39
L2fwd and swap has many options to set src mac. swap was supposed to support the ability to use port mac, but config file parsing was wrong. L2fwd was using port mac if a port was available and if src mac=packet or if there was no src mac in the config. Now l2fwd supports the following options - "src mac=xx:xx:xx:xx:xx:xx" => this mac address is used as src mac. - "src mac=packet" => the src mac is taken from the dst mac of the received packet. - "src mac=hw" => the src mac is taken from the mac address of the port, if there is a physical port. Error otherwise. - "src mac=no" => src mac kept untouched - No "src mac" => same as "src mac=hw" if there is a physical port and same as "src mac=packet" otherwise. Default is (no "src mac") hence the mac is taken from the tx port if there is one tx port and from the packet otherwise. swap support is similar, except that it does not support "src mac=no".

2017-12-18Add l3 support for tasks without physical tx portsXavier Simonart2-8/+5
This adds support for tasks in l3 submode receiving from ports but transmitting to rings. ARP related information is exchanged between tasks through master core. Tasks transmitting to physical ports are responsible to transmit arp related packets. Tasks not transmitting to physical ports (and using rings) should not try to transmit arp packets. Transmitting arp packets through ring would be more complex, as we would need extra information (within the mbuf) to distinguish for instance an arp reply comoing from the network and an arp reply coming from a core (as a reply to an arp request).

2017-11-15Add support for nop mode with l3 submodeXavier Simonart7-23/+52
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.
