Currently hand crafted with some sed scripts and alot of vim macros from
red_parse_qxl after considering the logger in qemu/hw/qxl-logger.c and seeing
it was incomplete. The only problem with logging from the server and
not from qemu is that it requires coordinated shutdown to avoid half a message.
Should be automatically generated from a declarative syntax, i.e. qxl.proto.
Note: zlib compression is introduced in a disabled state, see ZLIB
define
Now with a simple versioned header and generated ids by the server
instead of based on the recorded file, and doesn't use more then 1024
surfaces (configurable).

spice-server will attempt to limit number of monitors.
Guest machine can send monitor list it accepts. Limiting the number sent
by guest will limit the number of monitors client will try to enable.
The guest usually see client monitors enabled and start using it so
not seeing client monitor won't try to enable more monitor.
In this case the additional monitor guest can support will always be
seen as heads with no attached monitors.
This allows limiting monitors number without changing guest drivers.

With a SPICE_DISPLAY_CAP_MONITORS_CONFIG capable client, the client needs to
know what part of the primary to use for each monitor. If the guest driver
does not support this, the server sends messages to the client for a
single monitor spanning the entire primary.
As soon as the guest calls spice_qxl_monitors_config_async once, we set
the red_worker driver_has_monitors_config flag and stop doing this.
This is a problem when the driver gets unloaded, for example after a reboot
or when switching to a text vc with usermode mode-setting under Linux.
To reproduce this start a multi-mon capable Linux guest which uses
usermode mode-setting and then once X has started switch to a text vc. Note
how the client window does not only not resize, if you try to resize it
manually you always keep blackborders since the aspect is wrong.
This patch is the spice-server side of fixing this, it adds a new
spice_qxl_driver_unload method which clears the driver_has_monitors_config
flag.
The other patch needed to fix this is in qemu, and will calls this new method
from qxl_enter_vga_mode.

A Spice port channel carry arbitrary data between the Spice client and
the Spice server. It may be used to provide additional services on top
of a Spice connection. For example, a channel can be associated with
the qemu monitor for the client to interact with it, just like any
qemu chardev. Or it may be used with various protocols, such as the
Spice Controller.
A port kind is identified simply by its fqdn, such as org.qemu.monitor,
org.spice.spicy.test or org.ovirt.controller...
The channel is based on Spicevmc which simply tunnels data between
client and server, with a few additional messages.
See the description of the channel protocol in spice-common history.

New API: spice_server_set_ws_ports
This adds an optional dependency on libwebsockets. You need to get my
patched 0.0.3 version here:
git://people.freedesktop.org/~alon/libwebsockets
There is no qemu patches yet, to test change in reds.c the default value
of spice_ws_port to 5959 (for the default of spice-html5).
For testing there is an online client at
http://spice-space.org/spice-html5/spice.html
Known issues:
1. The tester (server/tests/test_display_no_ssl) gets into dropping all
data after a few seconds, I think it's an issue with the implemented
watches, but haven't figured it out.
2. libwebsocket's read interface is inverted to what our code expects,
i.e. there is no libwebsocket_read, so there is an additional copy
involved (see RedsWebSocket). This can be fixed.
3. Listening on a separate port. Since the headers are different, we
could listen on the same port (first three bytes RED/GET). I don't know
if we want to?
Todos:
1. SSL not implemented yet. Needs some thought as to how.
2. Serve spice-html5 when accessed as a http server. Nice to have.

Although global is the default, this makes the file more consistent.

a SpiceMsgDisplayMonitorsConfig is sent on two occasions:
* as a result of a spice_qxl_monitors_config_async
* whenever a client connects and there is a previously set monitors
config
Sending the new message is protected by a new cap,
SPICE_DISPLAY_CAP_MONITORS_CONFIG
More elaborately:
spice_qxl_monitors_config_async receives a QXLPHYSICAL address of a
QXLMonitorsConfig struct and reads it, caching it in the RedWorker, and
sending it to all clients. Whenever a new client connects it receives
a SpiceMsgDisplayMonitorsConfig message as well.

Add spice_server_set_name() and spice_server_set_uuid() that allows
the client to identify a Spice server (useful to associate settings
with a particular server)
The SPICE_MSG_MAIN_NAME and SPICE_MSG_MAIN_UUID messages are only sent
to capable clients, announcing SPICE_MAIN_CAP_NAME_AND_UUID.

Allow applications to pass a pre-accepted client socket file
descriptor in. The new APIs are spice_server_add_ssl_client
and spice_server_add_client
* server/reds.c: Implement new APIs
* server/spice.h: Define new APIs

spice_server_migrate_connect is in 0.8.3 in the released 0.8 branch,
and so should not be changed in 0.10. This doesn't break the 0.9.1
release which didn't contain this symbol at all, only 0.9.2 release
that hopefully no one actually packaged.

This does the following, all to remove any referenced memory on the pci bars:
flush_all_qxl_commands(worker);
flush_all_surfaces(worker);
red_wait_outgoing_item((RedChannel *)worker->display_channel);
red_wait_outgoing_item((RedChannel *)worker->cursor_channel);
The added api is specifically async, i.e. it calls async_complete
when done.

The new _ASYNC io's in qxl_dev listed at the end get six new api
functions, and an additional callback function "async_complete". When
the async version of a specific io is used, completion is notified by
calling async_complete, and no READY message is written or expected by
the dispatcher.
update_area has been changed to push QXLRects to the worker thread, where
the conversion to SpiceRect takes place.
A cookie has been added to each async call to QXLWorker, and is passed back via
async_complete.
Added api:
QXLWorker:
update_area_async
add_memslot_async
destroy_surfaces_async
destroy_primary_surface_async
create_primary_surface_async
destroy_surface_wait_async
QXLInterface:
async_complete
|

|
|
|
|
|

|

For each callback in QXLWorker, for example QXLWorker::update_area, add
a direct call named spice_qxl_update_area.
This will (a) remove the pointless indirection and (b) make shared
library versioning alot easier as we'll get new linker symbols which
we can tag with the version they appeared in the shared library.

This patch adds symbol versions to the spice server library. Each
symbol which is exported by libspice-server gets tagged with the
(stable) version where it appeared first. This way the linker and rpm
are able to figure which version of the spice-server libary is required
by a particular qemu binary/package.
