Supported DSLs
The languages Xtrace supports and the level at which each one inserts probes.
Agent skill
Xtrace inserts probes at one of two levels of the compilation stack.
Tip: SASS-level instrumentation offers the highest-fidelity tracing.
instrumentation_tier="ptx"
You mark scopes in the kernel source.
G-Watch turns each marker into a probe in the PTX.
ptxas then compiles the probes with the kernel.
