2026-01-12verification/dot2c: Remove superfluous enum assignment and add last commaGabriele Monaco
The header files generated by dot2c currently create enums for states and events assigning the first element to 0. This is superfluous as it happens automatically if no value is specified. Also it doesn't add a comma to the last enum elements, which slightly complicates the diff if states or events are added. Remove the assignment to 0 and add a comma to last elements, this simplifies the logic for the code generator.

2026-01-12rv: Refactor da_monitor to minimise macrosGabriele Monaco
The da_monitor helper functions are generated from macros of the type: DECLARE_DA_FUNCTION(name, type) \ static void da_func_x_##name(type arg) {} \ static void da_func_y_##name(type arg) {} \ This is good to minimise code duplication but the long macros made of skipped end of lines is rather hard to parse. Since functions are static, the advantage of naming them differently for each monitor is minimal. Refactor the da_monitor.h file to minimise macros, instead of declaring functions from macros, we simply declare them with the same name for all monitors (e.g. da_func_x) and for any remaining reference to the monitor name (e.g. tracepoints, enums, global variables) we use the CONCATENATE macro. In this way the file is much easier to maintain while keeping the same generality. Functions depending on the monitor types are now conditionally compiled according to the value of RV_MON_TYPE, which must be defined in the monitor source. The monitor type can be specified as in the original implementation, although it's best to keep the default implementation (unsigned char) as not all parts of code support larger data types, and likely there's no need. We keep the empty macro definitions to ease review of this change with diff tools, but cleanup is required. Also adapt existing monitors to keep the build working.

2025-07-28rv: Add nrp and sssw per-task monitorsGabriele Monaco
Add 2 per-task monitors as part of the sched model: * nrp: need-resched preempts Monitor to ensure preemption requires need resched. * sssw: set state sleep and wakeup Monitor to ensure sched_set_state to sleepable leads to sleeping and sleeping tasks require wakeup.
