The test creates tasks that pause until the children task have finished.
The value of the perf_event_paranoid file is checked to determine if we
can run the test.
As Nanos6 now emits pause events for the parent task before nesting
another one, we increase the minor so the old emulator rejects new
traces that come with the new pause events.
A consistency check ensures that all versions reported by the emulator
appear in the documentation as the latest version. This prevents
forgetting updating the version in the documentation.
The runtime tests check that we can submit and inline task (which must
emit a pause event before the nested task begins) and that we can run
parallel tasks.
The nOS-V events are modified in two ways: 1) to create a parallel task
the new VTC event must be used and 2) all task events for both normal
(VTc) and parallel (VTC) tasks require an extra argument in the payload
to indicate the body id. As a consequence, the nOS-V model version is
now increased to 2.0.0.
Additionally, all the channel PRV flags are set to PRV_SKIPDUPNULL, so
duplicates are only emitted if they are not null. It solves the problem
when a task switches to another task with the same body id.
A new Paraver configuration is added for the body id.
The task model is now integrated with the body model. A normal task can
only have one body, while a parallel task can have more.
It inherits the restriction that a task body cannot be nested over
another one unless it is paused (or the relaxed nest model is enabled).
The new task body model (or just body model) allows a task to have
multiple bodies. Generally a body is mapped to the execution of the same
user code of the task with specific input arguments.
The body model can constraint if a given body can be paused or re-run
again (resurrect).
Additionally, the body model can run multiple nested bodies but with the
restriction that the parent body should be paused first. This condition
can be relaxed with the BODY_FLAG_RELAX_NESTING flag.
This flag allows to only skip duplicates if the value is null, otherwise
the value is emitted. Invalid combinations of PRV_* flags are also
checked on prv_register().
Instead of showing the "attached" state with the VH{aA} events, we show
when the call to nosv_attach() and nosv_detach() take place. The old
VH{aA} events are now ignored. Bumps the nOS-V model version to 1.1.0.
The test ensures that the generated documentation of emulation events is
kept up to date. To locate the events.md file, the source root path is
now exported to tests in OVNI_SOURCE_DIR.
The "Built on ..." message with the date of the build is removed as
otherwise it will always make the comparison fail.
Implements a small language parser to define the emulator events. The
event specification is parsed at emulation (when the emulator runs).
The ovnidump output now prints the events with the arguments formatted
as given in the event description.
It also introduces some consistency checks over the event MCVs, which
must begin with the model identifier and cannot be duplicated.
Until now, the value returned by ovni_thread_isready() was still
non-zero when the thread stream was destroyed in ovni_thread_free()
This was making it impossible to detect when a stream was destroyed.
This change makes it return 0 after ovni_thread_free() by using a new
finished flag. The flag keeps track on then the stream is destroyed,
preventing double initialization of a free stream.
Causes the packages to always appear as found or not found in the
summary of cmake. Otherwise they were only checked if the compiler
supports the -fompss2 flag.
