The assert: spice_assert(pthread_equal(pthread_self(), client->thread_id)) and the assert: spice_assert(pthread_equal(pthread_self(), rcc->channel->thread_id)) were coded in order to protect data that is accessed from the main context (red_client and most of the channels), from access by threads of other channels (namely, the display and cursor channels), and vice versa. However, some of the calls to the sound channel interface, and also the char_device interface, can be done from the vcpu thread. It doesn't endanger these channels internal data, since qemu use global mutex for the vcpu and io threads. Thus, pthread_self() can be != channel->thread_id, if one of them is the vcpu thread and the other is the io-thread, and we shouldn't assert. Future plans: A more complete and complicated solution would be to manage our own thread for spice-channels, and push input from qemu to this thread, instead of counting on the global mutex of qemu rhbz#823472 |

SPICE: Simple Protocol for Independent Computing Environments
=============================================================
SPICE is a remote display system built for virtual environments which
allows you to view a computing 'desktop' environment not only on the
machine where it is running, but from anywhere on the Internet and
from a wide variety of machine architectures.
Installation
------------
The SPICE package uses GNU autotools, so the build install process
follows the standard process documented in the INSTALL file. As a
quick start you can do
./configure --prefix=/usr --sysconfdir=/etc \
--localstatedir=/var --libdir=/usr/lib
make
sudo make install
Or to install into a private user specific location
./configure --prefix=$HOME/spice
make
make install
The following mandatory dependancies are required in order to
build SPICE
Spice protocol >= 0.9.0
Celt >= 0.5.1.1, < 0.6.0
Pixman >= 0.17.7
OpenSSL
libjpeg
zlib
Cyrus-SASL
The following optional dependancies increase the available
functionality
GE Gui >= 0.6.0, < 0.7.0 (GUI app support)
OpenGL (GUI app support)
Alsa (Linux support)
XRandR >= 1.2 (X11 support)
Xinerama >= 1.0 (X11 support)
libcacard >= 0.1.2 (Smartcard support)
Slirp (Tunnelling support)
Communication
-------------
To communicate with the development team, or to post patches
there is a technical mailing list:
http://lists.freedesktop.org/mailman/listinfo/spice-devel
There is also a mailing list for new release announcements:
http://lists.freedesktop.org/archives/spice-announce/
To view known bugs, or report new bugs, in SPICE visit
https://bugs.freedesktop.org/describecomponents.cgi?product=Spice
Bugs found when using an OS distribution's binary packages should
be reported to the OS vendors' own bug tracker first.
The latest SPICE code can be found in GIT at:
http://cgit.freedesktop.org/spice/
