2011-09-19spice: add migration interfacemig.spice.v42Yonit Halperin1-1/+53
- call spice_server_migrate_(start|end). - register client_migrate_info completion callback
2011-09-19spice: turn client_migrate_info to asyncYonit Halperin5-9/+26
RHBZ 737921 Spice client is required to connect to the migration target before/as migration starts. Since after migration starts, the target qemu is blocked and cannot accept new spice client we trigger the connection to the target upon client_migrate_info command. client_migrate_info completion cb will be called after spice client has been connected to the target (or a timeout). See following patches and spice patches.

2011-09-07spice: set qxl->ssd.running=true before telling spice to start, RHBZ #733993Yonit Halperin1-1/+2
If qxl->ssd.running=true is set after telling spice to start, the spice server thread can call qxl_send_events while qxl->ssd.running is still false. This leads to assert(d->ssd.running). Signed-off-by: Yonit Halperin <yhalperi@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-09-07qxl: send interrupt after migration in case ram->int_pending != 0, RHBZ #732949Yonit Halperin1-2/+8
if qxl_send_events was called from spice server context, and then migration had completed before a call to pipe_read, the target guest qxl driver didn't get the interrupt. In addition, qxl_send_events ignored further interrupts of the same kind, since ram->int_pending was set. As a result, the guest driver was stacked or very slow (when the waiting for the interrupt was with timeout).

2011-09-03Add new macro QEMU_PACKED for packed C structuresStefan Weil1-0/+6
A packed struct needs different gcc attributes for compilations with MinGW compilers because glib-2.0 adds compiler flag -mms-bitfields which modifies the packing algorithm. Attribute gcc_struct reverses the negative effects of -mms-bitfields. QEMU_PACKED sets this attribute and must be used for any packed struct which is affected by -mms-bitfields.

Fix install(1) usage to be compatible with OpenBSD's install(1). When creating a directory via the -d flag the -p flag cannot be used at the same time.

2011-09-02main: force enabling of I/O threadAnthony Liguori6-232/+1
Enabling the I/O thread by default seems like an important part of declaring 1.0. Besides allowing true SMP support with KVM, the I/O thread means that the TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which currently requires a (racey) signal based alarm system. I know there have been concerns about performance. I think so far the ones that have come up (virtio-net) are most likely due to secondary reasons like decreased batching. I think we ought to force enabling I/O thread early in 1.0 development and commit to resolving any lingering issues. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-09-01build: sort objects to remove duplicates for linkStefan Hajnoczi1-1/+1
Avoid duplicate object files during the link. There are legitimate cases where a link command-line would include duplicate object files because two independent subsystems both depend on common infrastructure. Use GNU make's $(sort) function to remove duplicate object files from the link command-line.

2011-09-01main: switch qemu_set_fd_handler to g_io_add_watchAnthony Liguori1-1/+56
This patch changes qemu_set_fd_handler to be implemented in terms of g_io_add_watch(). The semantics are a bit different so some glue is required. qemu_set_fd_handler2 is much harder to convert because of its use of polling. The glib main loop has the major of advantage of having a proven thread safe architecture. By using the glib main loop instead of our own, it will allow us to eventually introduce multiple I/O threads. I'm pretty sure that this will work on Win32, but I would appreciate some help testing. I think the semantics of g_io_channel_unix_new() are really just tied to the notion of a "unix fd" and not necessarily unix itself. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2011-09-01Add glib support to main loopAnthony Liguori1-0/+74
This allows GSources to be used to register callback events in QEMU. This is useful as it allows us to take greater advantage of glib and also because it allows us to write code that is more easily testable outside of QEMU since we can make use of glib's main loop in unit tests. All new code should use glib's callback mechanisms for registering fd events which are very well documented at: http://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html And: http://developer.gnome.org/gio/stable/ Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
