2010-12-09spice: connection events.Gerd Hoffmann
This patch adds support for connection events to spice. The events are quite simliar to the vnc events. Unlike vnc spice uses multiple tcp channels though. qemu will report every single tcp connection (aka spice channel). If you want track spice sessions only you can filter for the main channel (channel-type == 1). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-12-09spice: add qxl deviceGerd Hoffmann
qxl is a paravirtual graphics card. The qxl device is the bridge between the guest and the spice server (aka libspice-server). The spice server will send the rendering commands to the spice client, which will actually render them. The spice server is also able to render locally, which is done in case the guest wants read something from video memory. Local rendering is also used to support display over vnc and sdl. qxl is activated using "-vga qxl". qxl supports multihead, additional cards can be added via '-device qxl". [ v2: add copyright to files ] [ v2: use qemu-common.h for standard includes ] [ v2: create separate qxl-vga device for primary ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-12-04*-dis: Replace fprintf_ftype by fprintf_function (format checking)Stefan Weil
This patch adds more printf format checking. Additional modifications were needed for this code change: * alpha-dis.c: The local definition of MAX conflicts with a previous definition from osdep.h, so add an #undef. * dis-asm.h: Add include for fprintf_function (qemu-common.h). The standard (now redundant) includes are removed. * mis-dis.c: The definition of ARRAY_SIZE is no longer needed and must be removed (conflict with previous definition from qemu-common.h). * sh4-dis.c: Remove some unneeded forward declarations.

2010-12-03ARM: linux-user: Restore VFP state from ucontext on sigreturnPeter Maydell
Restore the VFP registers from the ucontext on return from a signal handler in linux-user mode. This means that signal handlers cannot accidentally corrupt the interrupted code's VFP state, and allows them to deliberately modify the state via the ucontext structure.

2010-12-03ARM: linux-user: Expose VFP registers to signal handlersPeter Maydell
For ARM linux-user mode signal handlers, fill in the ucontext with VFP register contents in the same way that the kernel does. We only do this for v2 format sigframe (2.6.12 and above); this is actually bug-for-bug compatible with the older kernels, which don't save and restore VFP registers either.

2010-12-03linux-user: Translate getsockopt level optionJamie Lentin
n setsockopt, the socket level options are translated to the hosts' architecture before the real syscall is called, e.g. TARGET_SO_TYPE -> SO_TYPE. This patch does the same with getsockopt. Tested on a x86 host emulating MIPS. Without it:- $ grep getsockopt host.strace 31311 getsockopt(3, SOL_SOCKET, 0x1007 /* SO_??? */, 0xbff17208, 0xbff17204) = -1 ENOPROTOOPT (Protocol not available) With:- $ grep getsockopt host.strace 25706 getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0 Whitespace cleanup: Riku Voipio Signed-off-by: Jamie Lentin <jm@lentin.co.uk> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>

2010-12-03linux-user: fix memory leaks with NPTL emulationNathan Froyd
Running programs that create large numbers of threads, such as this snippet from libstdc++'s pthread7-rope.cc: const int max_thread_count = 4; const int max_loop_count = 10000; ... for (int j = 0; j < max_loop_count; j++) { ... for (int i = 0; i < max_thread_count; i++) pthread_create (&tid[i], NULL, thread_main, 0); for (int i = 0; i < max_thread_count; i++) pthread_join (tid[i], NULL); } in user-mode emulation will quickly run out of memory. This is caused by a failure to free memory in do_syscall prior to thread exit: /* TODO: Free CPU state. */ pthread_exit(NULL); The first step in fixing this is to make all TaskStates used by QEMU dynamically allocated. The TaskState used by the initial thread was not, as it was allocated on main's stack. So fix that, free the cpu_env, free the TaskState, and we're home free, right? Not exactly. When we create a thread, we do: ts = qemu_mallocz(sizeof(TaskState) + NEW_STACK_SIZE); ... new_stack = ts->stack; ... ret = pthread_attr_setstack(&attr, new_stack, NEW_STACK_SIZE); If we blindly free the TaskState, then, we yank the current (host) thread's stack out from underneath it while it still has things to do, like calling pthread_exit. That causes problems, as you might expect. The solution adopted here is to let the C library allocate the thread's stack (so the C library can properly clean it up at pthread_exit) and provide a hint that we want NEW_STACK_SIZE bytes of stack. With those two changes, we're done, right? Well, almost. You see, we're creating all these host threads and their parent threads never bother to check that their children are finished. There's no good place for the parent threads to do so. Therefore, we need to create the threads in a detached state so the parent thread doesn't have to call pthread_join on the child to release the child's resources; the child does so automatically. With those three major changes, we can comfortably run programs like the above without exhausting memory. We do need to delete 'stack' from the TaskState structure.
