Supposed to be used for work-in-progress bits,
where interfaces are not finalized yet.
Moved over vdi port interface, tunnel interface
and spice client migration functions.
|
| |
|
|
| |
move over content to spice.h
|
| |
|
|
|

Drop leftover bits which are not used any more.
Rename DrawArea to QXLDrawArea.
|
| | |
|
| |
|
|
| |
Remove remaining MigrationInterface bits.
|
| |
|
|
| |
Add new API for migration, based on what RHEL-6 has.
|
| | |
|
| |
|
|
| |
Drop all code which depends on accessing the migration file handle.

Add worker->loadvm_commands. qemu will uses this to send a series of
commands needed to restore state after savevm/loadvm and migration.
That will be one create-surface command per surface and one cursor-set
command for the local pointer.
The worker->save/load functions are not needed any more.
Likewise the interface->{get,set}_save_data callbacks.
Surfaces created via loadvm_commands *will* not be cleared. Also
primary surfaces are not cleared any more (unconditionally, although
we could do that conditionally on loadvm using the flags field in
QXLSurfaceCreate).

With this patch applied the spice server will not release surface create
commands for the whole lifecycle of the surface. When the surface is
destroyed both create and destroy commands are released.
This has the effect that the surface metadata (size, depth, ...) is kept
in qxl device memory. This in turn makes it alot easier for qemu to
handle savevm/loadvm. It just needs to do some minimal command parsing
and maintain pointers to the create commands for the active surfaces.

Not needed. Just register/unregister the tablet interface instead.

Pretty straight forward.
One thing we should think about is if and how we are going to deal
with multiple ports here?
With vdi port using virtio-serial as communication channel to the guest
it is easy to have multiple ports, i.e. we might want to use a second
instance for clipboard data. That implies that we need support for
multiple channels all the way through the stack ...

This is the direction I wanna take with all interfaces: Clearly
separate interface (aka version information and function pointers)
and state information. SpiceKbdInterface defines the interface,
SpiceKbdInstance maintains per-instance state information. Keyboard
hasn't much beside a pointer to SpiceKbdInterface, for other
interfaces this very likely will be different.

VDInterface has been renamed to SpiceBaseInterface. Dropped base_version
element, shlib versioning should be used instead. Dropped id element,
it is passed to spice_server_add_interface() instead. Now
SpiceBaseInterface has static information only, multiple interface
instances can share it.
Added SpiceBaseInstance struct for maintaining per-instance state
information. Adapted spice_server_{add,remove}_interface() functions
to the new world.

Make the timer interface largely look like the watch interface.
Simliar naming convention for the functions (timer_*) and a
opaque SpiceTimer type.

This patch adds a new file handle watch interface to libspice, featuring
three callbacks:
(1) watch_add() -- create a new file watch.
(2) watch_update_mask() -- change event mask. spice frequently
enables/disables write notification.
(3) watch_remove() -- remove a file watch.
libspice users must implement these functions to allow libspice
monitoring file handles.
The old interface (set_file_handlers) doesn't explicitly express the
lifecycle of a watch. Also it maps 1:1 to a qemu-internal function.
In case the way qemu implements file watches changes (someone sayed
QemuIONotifier?) this will break horribly. Beside that it is very
bad style.
Follwing patches will switch over users one by one to the new interface
and finally zap the old one.

Was used to print stuff to the qemu monitor.
Fundamentally incompatible with QMP. Remove.
|
| |
|
|
| |
old way to handle monitor, obsolete.
|
| |
|
|
|

spice_server_add_interface() and spice_server_remove_interface()
can be used instead.
|
| |
|
|
|
|
|
| |
Interfaces must be registered after spice_server_init().
The "next" callback is used to discover interfaces
registered before spice_server_init(). Which is a empty
list and thus pretty pointless. Remove it.

- drop spice_channel_name_t enum, use spice-protocol defines instead.
- switch spice_server_set_channel_security() channel parameter from
enum to string.
- drop spice_server_set_default_channel_security(), use
spice_server_set_channel_security with channel == NULL instead.

First step to throw out the old interface.

Cyclic dependencies between surfaces mustn't occur. They can cause invalid rendering -
recent drawables might be rendered before older ones.

The command line option is renamed from "cairo" to "sw", and
similarly all filenames and types from Cairo to Sw (and similar).

The framebuffer is not used as a source for alpha blends, so we never
need to scan it for alpha bytes.

Adds sanity check to iovec setup. In theory this should never ever
trigger. In practice guest driver bugs can make it trigger. This
patch avoids qemu burning cpu in a endless loop, instead we'll print a
message and abort. Not sure whenever there is a more graceful way to
handle the situation ...

If we don't then alpha is lost which is problematic if the surface
is later used as with alpha_blend and SRC_SURFACE_HAS_ALPHA.
