- P4 architecture - P4 Programming Language
The P4 16 language version (this is a perception more than a fact) seems to have put the PISA term aside P4 16 also required the “architecture” concept (like V1Model) so the concept of PISA made more sense to how you define the pipeline when talking about P4 14-programmable targets
- Register manipulation - Getting Started with P4 - P4 Programming Language
Hello, I’ve some questions regarding registers in P4 that I’d appreciate if someone could clarify: When I use read in a register am I taking out the stored value or does the value remain stored? If a value is stored within a register position, does writing in that position replace the previous content? Is there any way to fully erase reset the content stored within a register? Thanks
- All Time - P4 Programming Language
A place to discuss the P4 Programming Language and Ecosystem After the Onos connects to the p4 switch, there is a problem that the device is not online
- Intel P4 Studio - P4 Dev - P4 Programming Language
Folks, I am leading a research group at a university We want to use P4 for CPS applications and are in the process of purchasing two Tofino2 switches For that, I recently applied for the Intel Connectivity Research Program to obtain the Intel P4Studio before we can buy the hardware The notification says there is a 20-business-day lead time for verification Those who recently joined just
- How tables work? - Getting Started with P4 - P4 Programming Language
PD: And just to be clear, I call a P4 device a switch, but it can parse L2, L3 and L4 headers, and even application layers headers if that makes sense to your use case So this is not only a typical L2 switch but rather a device that acts in pretty much all layers
- Match-Action Table with multiple types of keys - P4 Programming Language
Suppose that you had a P4 table with field f1 that was range match kind, and field f2 was ternary match kind If the control plane added a rule where f1 was range [0, 5], and field f2 was value V with mask M, then a system that used power-of-2-aligned TCAM entries to implement the range match kind would install 2 TCAM entries for this control
- Difference between P4 architectures - PISA vs PSA
The P4_16 language spec includes a sample P4_16 architecture, called “Very Simple Switch Architecture” to illustrate the necessary points PSA, PNA, v1model, TNA, T2NA and a number of others are all P4_16 architectures, with the formally defined interfaces, coded in P4_16 language
- Debugging a P4 code in general - P4 Programming Language
As for your specific method (assigning the values in question to some temporary metadata and watching the logs), again, a lot will depend on the specific target For example, if these assignments have no further effect on the execution, an optimizing P4 compiler will probably remove them as a part of dead code elimination pass
