Subject: [PATCH v2 09/24] macio: Fix to realize "mos6522-cuda" and "mos6522-pmu" devices
Date: Thu, 28 May 2020 13:04:29 +0200	[thread overview]
Message-ID: <20200528110444.20456-10-armbru@redhat.com> (raw)
In-Reply-To: <20200528110444.20456-1-armbru@redhat.com>

cuda_init() creates a "mos6522-cuda" device, but it's never realized.
Affects machines mac99 with via=cuda (default) and g3beige.

pmu_init() creates a "mos6522-pmu" device, but it's never realized.
Affects machine mac99 with via=pmu and via=pmu-adb,

In theory, a device becomes real only on realize.  In practice, the
transition from unreal to real is a fuzzy one.  The work to make a
device real can be spread between realize methods (fine),
instance_init methods (wrong), and board code wiring up the device
(fine as long as it effectively happens on realize).  Depending on
what exactly is done where, a device can work even when we neglect
to realize it.

These onetwo appear to work.  Nevertheless, it's a clear misuse of the
interface.  Even when it works today (more or less by chance), it can
break tomorrow.

Fix by realizing them in cuda_realize() and pmu_realize(),
respectively.
