The core's IRQ and FIQ lines were set from WiiIPC's flags and masks only at
the start of each scheduler slice (Starlet::RunSlice, StarletBootstrapProbe).
Acknowledging an interrupt (HW_ARMIRQFLAG, write one to clear) or masking it
(HW_ARMIRQMASK) left the line asserted until the next slice, so code that
acknowledged an interrupt and unmasked IRQ within the same slice took it
again with no cause pending. Hollywood's interrupt output is level-sensitive.
StarletMemory now re-samples the lines of the core attached with
AttachInterruptLines on every write to those two registers, on both its
wide and byte-assembled write paths; Starlet and StarletBootstrapProbe
attach theirs. Raising a cause still reaches the core at the next slice, as
before. ARMCore exposes IsIRQLineAsserted and IsFIQLineAsserted for the
unit test.

The probe printed the ring's length only. StarOS's EXP-003 images put
lines in the ring that REV_TRACE has no room for (the MEM2 monitor, the
measurements), so under Dolphin nothing showed them. After the record's
summary, --sbr1-record now prints the ring's text between "SBR1 RING
BEGIN" and "SBR1 RING END" on stderr, as StarOS's Broadway loader prints
it over the Gecko on the console: at most the ring's 4032 bytes, a byte
outside printable ASCII and newline, and the backslash, written \xHH.
The formatting is in ProbeRing.h, tested by StarletProbeRingTest.

The probe ran every image for a fixed 512 slices of 4096 ARM cycles
(2097152). StarOS's EXP-003 images hash MEM2 and time series of
operations, which need more (StarOS experiments/proposals/mmu-console.md,
P-7 and P-8). --cycles <n> sets the budget: a decimal number of cycles,
a whole number of slices, from one slice to 2^30, given once; anything
else is a usage error (exit 2), never rounded. Without it the probe runs
2097152 cycles, as before, and the timeout messages name the budget.
The parser is in ProbeBudget.h, tested by StarletProbeBudgetTest.

--expect-panic passed as soon as __panic_state was nonzero at the end of
a 4096-cycle slice. StarOS's handler stores the guard first, then the
code, then publishes the SBR1 record, so the run could stop with the path
half done. The probe now keeps running until the path is finished and
still is two slices later, and fails if the run budget ends first:
- __panic_state 1 and __panic_code 1;
- with --sbr1-record: STARLET_STATE 5 (Panic), FATAL_REASON 0 and
EXI_OWNER 1 (handed back to the PPC);
- with --sbr1-absent: every word of the record area still zero.
The failure names the first unmet condition. The check is
StarOSPanicCheck.h, pure, with the SBR1 constants moved there, and
StarletProbePanicCheckTest covers each condition; each of 7 mutants of
the check fails a test. Runs that do not expect a panic are unchanged.
With StarOS's panic test image (eb930ee), interpreter and JIT: the
scenarios pass, two slices later than before. Three images derived from
it pass the previous probe and now fail: EXI kept by the Starlet
(--sbr1-record), __panic_code never stored, the record written although
absent (--sbr1-absent). (StarOS MMU-001 review of F1.)

StarOS's SBR1 boot record (MEM1 0x00200000) is created by its Broadway
loader before the image runs; the probe never had one, so the paths
that publish into it ran only on the console. --sbr1-record writes the
record as the loader and the ARM relay leave it (header, relay at its
last step, EXI channel 1 given to the Starlet, magic last); after the run
both options print the record's magic, state, reason, EXI owner, fault
code, ring length and dropped count, and how many of its 1024 words are
nonzero (0 is expected with --sbr1-absent). Without either option the
probe behaves as before.
With the StarOS M1 images (interpreter and JIT): idle publishes state 3
and hands EXI back (owner 1, ring 258 bytes, no Gecko emulated);
fatal-data state 4 reason 3; undefined-entry state 6, fault 1, ring
empty, as on the console (gates HW2-HW4).

StarOS's panic path (ADR-0014 R6) writes no trace line: it sets the guard
word __panic_state, stores __panic_code and halts. LoadBootstrapELF now
returns both symbols when an image has them (optional, but both or
neither, as words of the data segment), and the probe stops a run whose
guard is set: it prints the trace published so far and
"Starlet panic state <n> code <n>", and passes --expect-panic when the
state is 1. Images without these symbols (StarletOS) load and run as
before; a REV:PANIC trace line still satisfies --expect-panic.

Enables the ARM926 MMU aborts of ARMCore (SetMMUFaultsEnabled) for the
run. Without the option the probe behaves as before.

The probe never initialised Dolphin's MEM1 and MEM2, so any Starlet
access there was an access to unmapped memory: StarOS reads its SBR1
record header at 0x00200000 on every boot, which raised two alerts
(Unknown Pointer, then Invalid range in CopyFromEmu) and read 0. The
probe now initialises both, zeroed, at their retail sizes (24 and
64 MiB), and shuts them down after the run. The read still returns 0.

With no handler registered, Dolphin shows an alert in a modal MessageBox
on Windows, and the probe waits until someone closes it. A run that hits
an alert then looks like a hang (StarOS EXP-001). The probe now writes the
alert to stderr and exits at once with status 3.

Recover 16 modified and 6 previously untracked integration files. All 22 source SHA-256s match the pre-publication StarletOS snapshot. Add handoff instructions, byte-preserving attributes and private backup exclusion. This commit publishes existing behavior; it does not claim a new full build or hardware qualification. The two preceding local commits and staged files were screened before publication.
Boot original Wii firmware through boot0, boot1, boot2 and IOS on an emulated ARM Starlet. Model the required IPC, memory, SD, USB and Bluetooth hardware behavior, including IOS reload into IOS58, and add focused tests, launch utilities and architecture documentation.
With our current setup, we use the --deep option, which should be avoided.
This tool signs bundles in the "correct" way as recommended by Apple (each Mach-O individually, from the inside-out).
Starting with grep 3.8, egrep throws the following warning
egrep: warning: egrep is obsolescent; using grep -E
Whch is annoying... so we will use grep -E
Maybe a little wonky, but I needed a way to run unit tests
on AArch64, and this was the best way of running unit tests
on Android that I could come up with.
This updates the lint script to require clang-format 9 and reformats
existing source code. Since VS2019 ships with clang-format 9 this
should make auto reformats less painful.
This also updates the clang-format configuration to set
BraceWrapping.AfterCaseLabel to true to ensure consistent brace
style; otherwise clang-format 9+ defaults to putting braces on
the same line as switch case labels.
This requires buildbot changes: the path to the Android Studio
installation must be supplied in an environment variable.
Modified files are copied out to a temporary directory, Android Studio
is asked to format the files, and a git diff is performed.
Now fails if any commands fail. I noticed that on the buildbot, the
arguments to this script can be incorrect (somehow?) which can result in
no lint checks happening but the buildbot still passing.
