The probe stands in for Broadway, so that a real request can enter StarOS's
image through the Hollywood IPC registers and its reply be read back (StarOS
docs/contracts/hollywood-ipc-injection.md, approved for development). A
script is data: whole words stored in one range of PPC memory,
0x135E0000..0x13600000, PPCMSG and PPCCTRL written, PPCCTRL and ARMMSG read,
every wait bounded in ARM cycles. Steps run between the probe's slices. The
probe knows nothing of the code under test and answers nothing for it.
A script refused when read ends the run with exit status 5, before StarOS
starts. A step that fails, or a terminal trace line with steps left, fails
the run with its line on stderr. The option given twice, or without its
file, is a usage error.
The one change in Source/Core: WiiIPC::SetStarletAttached, an opt-in flag
UpdateInterrupts reads beside GetStarlet(), because the probe runs an
ARMCore with no Starlet object in the System. The IPC cause is then raised
by the model's own line, X1 and IX1 included, with no second model of it.
Reset clears the flag, and nothing sets it without --ipc-script.
ProbeScript.h holds the parser and the runner, tested by
StarletProbeScriptTest over a fake bus; StarletProbeInterruptTest holds the
flag's behaviour with and without it.
