Add MMDC, OCOTP, SQPI, CAAM, and USBMISC as unimplemented devices.
This allows operating systems such as Linux to run emulations such as
mcimx6ul-evk.
Before commit 0cd4926b85 ("Refactor i.MX6UL processor code"), the affected
memory ranges were covered by the unimplemented DAP device. The commit
In the specific case where the display layer (virtio-gpu) is using
dmabuf, and if remote clients are enabled (-spice gl=on,port=),
it makes sense to limit the maximum (streaming) rate to 60 FPS
using the GUI timer. This matches the behavior of GTK UI where the
display updates are submitted at 6
When testing with gl=on on an Intel Host, it was noticed that the
R and B channels were interchanged while the Guest FB image was
displayed. This was only seen if the display layer (virtio-gpu)
did not directly share the dmabuf fd with Spice (i.e, blob=false).

In some cases where a UI component (e.g, Spice) needs to choose
a particular glformat for a surface while creating a texture,
this new GLenum provides an option to do so. One situation
where this needs to be done is when the Host endianness is
causing issues such as interchanged R and B channels.
To address the limitation that this option is incompatible with
remote clients, this patch series adds an option to select a
preferred codec and also enable gl=on option for clients that
are connected via the network. In other words, with this option

Since most encoders (invoked by Spice) may not work with tiled memory

There are cases where we do not want the memory layout of a texture to

Switch vmbus from using BusClass::reset to the Resettable interface.
This has no behavioural change, because the BusClass code to support
subclasses that use the legacy BusClass::reset will call that method
in the hold phase of 3-phase reset.

This patchset switches the handful of bus types that implement a
reset method over to using the 3-phase-reset APIs, and then removes
the transitional infrastructure from the core bus class that was
supporting the ability to have bus types that use old-style reset.
I wrote this ages ago and recentl

BusClass currently has transitional infrastructure to support
subclasses which implement the legacy BusClass::reset method rather
than the Resettable interface. We have now removed all the users of
BusClass::reset in the tree, so we can remove the transitional
infrastructure.
