Subject: [PATCH 2/7] hw/misc/empty_slot: Lower address space priority
Date: Sun, 10 May 2020 17:28:35 +0200 [thread overview]
Message-ID: <20200510152840.13558-3-f4bug@amsat.org> (raw)
In-Reply-To: <20200510152840.13558-1-f4bug@amsat.org>
Empty slots model RAZ/WI access on a bus. Since we can still
(hot) plug devices on the bus, lower the slot priority, so
device added later is accessed first.
