2009-02-05Terminate emulation on memory allocation failure (Avi Kivity)aliguori
Memory allocation failures are a very rare condition on virtual-memory hosts. They are also very difficult to handle correctly (especially in a hardware emulation context). Because of this, it is better to gracefully terminate emulation rather than executing untested or even unwritten recovery code paths. This patch changes the qemu memory allocation routines to terminate emulation if an allocation failure is encountered.

2009-02-02Add phenom CPU descriptor (Alexander Graf)aliguori
As part of my ongoing effort to make nested SVM useful, I started working to get VMware ESX run inside KVM. VMware couples itself pretty tightly to the CPUID, so it's a good idea to emulate a machine that officially supports SVM and should thus exploit the powers of nested virtualization. This patch adds a Phenom CPU identifier, that resembles a real-world phenom CPU as closely as possible.

2009-02-02Move the framebuffer update package out (Alexander Graf)aliguori
Currently the send_framebuffer_update_raw and send_framebuffer_update_hextile respectively send a send_framebuffer_update packet themselves. We need to reuse send_framebuffer_update_raw for zlib encoding though, so let's move it out.

2009-02-02Add some tight awareness to vnc.c (Alexander Graf)aliguori
This patch enables the vnc server to understand fundamental tight extensions. It changes from a "Hextile or not" scheme when sending framebuffer updates to a "preferred encoding", namely the last one set. While this is not perfect, as actually a list of "preferred encodings" should be kept, it's good enough for now.

2009-02-02Use VNC protocol defines (Alexander Graf)aliguori
Now that we have nice defines for all sorts of constants, let's use them! This patch also takes the "feature variables", currently called has_* into a single feature int. This way adding new features is a lot easier and doesn't clutter the VncState struct.

2009-02-02Split VNC defines to vnc.h (Alexander Graf)aliguori
The VNC protocol contains quite some constants, some of which are currently hardcoded in the vnc.c code. This is not exactly pretty. Let's move all those constants out to vnc.h, so they are clearly separated. While at it, I also included other defines that will be used later in this patch series.
