Re: [PATCH v7 08/10] accel/rocket: add RK3576 NPU (RKNN) support

Hi Jiaxing,

Two short things.

On synchronize_irq(): your placement is right and my question was not
thought through that far. Inside the guard it would wait for a handler
that is itself waiting for job_lock, which is a deadlock rather than a
fence. Before it, with nothing held and both callers in process
context, is the only place it works. I had the window right and the
location wrong.

I will run v8 on the three cores here when it is out, and I will drive
the reset path deliberately rather than wait for a timeout to happen on
its own, since that is the path the two changes are there for.

On MobileNet: 995 of 1001 within one count is a different kind of
number from what this series has been reporting, and it took four Mesa
faults to get there. That is worth saying out loud.

If it would help to know whether the remaining six are RK3576 specific
or common to the stack, I can run the same comparison on RK3588. I
already run MobileNet V1 through the Teflon delegate here, but my
oracle is bit-exactness across repeated runs rather than a per-output
comparison against the CPU, so it would not have noticed six outputs
being off by more than a count. Say the word and I will point it at the
CPU reference the way you did.
