=== GetState ===
=== GetState ===
No input. Returns an u32 '''State''' (0=Started, 1=Stopped).
No input. Returns an u32 '''State''' (0=Started, 1=Stopped).
The output is determined using the flag updated by [[#Start|Start]]/[[#Stop|Stop]].
=== RequestUpdate ===
Takes two type-0x6 output buffers and a type-0x5 input buffer.
=== Start ===
No input/output.
Besides logging, this calls a func which essentially clears a state field and sets a flag, and also calls a func.
The thread which handles generating/sending ADSP commands will only do so when the above flag indicates the state is Started.
=== Stop ===
No input/output.
After logging, this calls a func which essentially returns when the flag from [[#Start|Start]] is not set. Various funcs are called, then the flag is cleared. If needed, this waits on an event, then this returns.
=== QuerySystemEvent ===
No input, returns an output Event handle.

No input. Returns an u32 '''RenderingTimeLimit'''.
=== RequestUpdateAuto ===
Takes two type-0x22 output buffers and a type-0x21 input buffer.
This is identical to [[#RequestUpdate|RequestUpdate]] besides the buffer-types.

= Notes =
Once nnMain finishes running, it calls a func which handles ADSP Aborts. This waits on an event, calls a func, then Aborts with Result 0xC0899.
That func just calls another func, which:
* Calls various AGIC funcs for this IRQ, etc.
* Copies data from devicemem+0x608C (the 0x7000-byte devicemem "shared memory segment") to a stack struct.
* A funcptr is called if set with the above struct, then this returns.
That funcptr, besides other func-calls, will log an [[Error_Report_services|erpt]] using the input struct when set with the "AdspException*" fields.
This is triggered by AGIC IRQ adsp_wdresetreq, "ADSP Watchdog Timer Reset Request". The ADSP updates the watchdog from a thread, so normally the watchdog only expires when the ADSP configures it to trigger immediately.
When handling an assert/exception, the ADSP:
* Logs exception info in text form into devicemem.
* Logs the binary form of the exception into devicemem (offset above).
* Eventually configures the watchdog to trigger immediately, prints "HALT: spinning forever...\n", then enters a loop using instruction "wfe".
