Subject: Re: [Qemu-devel] [PATCH v11 0/8] Add a generic loader
Date: Tue, 27 Sep 2016 10:14:00 -0400 (EDT)	[thread overview]
Message-ID: <1764179128.3091209.1474985640517.JavaMail.zimbra@redhat.com> (raw)
In-Reply-To: <87lgydii9w.fsf@dusky.pond.sub.org>

It does whatever cpu_physical_memory_write_rom (and hence
cpu_memory_rw_debug, which has more callers) do.

/dev/null

> What happens when you try to monkey-patch some device's ROM?

Overwritten.

> Memory-mapped I/O?

Ignored.

> What happens when you monkey-patch persistent memory, such as pflash
> backed by a block backend?

Overwritten (but not flushed).

> What happens if the address range crosses device boundaries?

Writes over each area separately.

Yes, of course.
