2016-02-23scripts/clean-includes: Ignore .inc.c filesPeter Maydell1-0/+5
Ignore files which have a .inc.c extension -- these are not headers but they are not standalone C source files either, so we can't make any automated decisions about what #include directives they should have.

2016-02-23tcg: Rename tcg-target.c to tcg-target.inc.cPeter Maydell14-9/+11
Rename the per-architecture tcg-target.c files to tcg-target.inc.c. This makes it clearer that they are not intended to be standalone C files, but are instead #included into another source file.

2016-02-23scripts/clean-includes: Enhance to handle header filesPeter Maydell1-8/+45
Enhance clean-includes to handle header files as well as .c source files. For headers we merely remove all the redundant #include lines, including any includes of qemu/osdep.h itself. There is a simple mollyguard on the include file processing to skip a few key headers like osdep.h itself, to avoid producing bad patches if the script is run on every file in include/.

2016-02-23osdep.h: Define macros for the benefit of C++ before C++11Peter Maydell1-0/+14
For C++ before C++11, <stdint.h> requires definition of the macros __STDC_CONSTANT_MACROS, __STDC_LIMIT_MACROS and __STDC_FORMAT_MACROS in order to enable definition of various macros by the header file. Define these in osdep.h, so that we get the right header file definitions whether osdep.h is being used by plain C, C++11 or older C++. In particular libvixl's header files depend on this and won't compile if osdep.h is included before them otherwise.

2016-02-23Postcopy+spice: Pass spice migration data earlierDr. David Alan Gilbert3-1/+20
Spice hooks the migration status changes to figure out when to transmit information to the new spice server; but the migration status in postcopy doesn't quite fit - the destination starts running before the end of the source migration. It's not a case of hanging off the migration status change to postcopy-active either, since that happens before we stop the guest CPU. Fix it by sending a notify just after sending the device state, and adding a flag that can be tested by the notify receiver.

2016-02-23spice: add opengl/virgl/dmabuf supportGerd Hoffmann4-4/+140
This adds support for dma-buf passing to spice. This makes virtio-gpu with 3d acceleration work with spice. Workflow: * virglrenderer renders the guest command stream into a texture. * qemu exports the texture as dma-buf and passes on that dma-buf to spice-server. * spice-server passes the dma-buf to spice-client, using unix socket file descriptor passing. * spice-client asks the window systems composer to render the dma-buf to the screen. Requires cutting edge spice (server) and spice-gtk (client) builds, from git master branch. Also requires libvirt managing your qemu instance, and using "virt-viewer --attach $guest". libvirt will connect spice-server and spice-client using unix sockets instead of tcp sockets then, which is required for file descriptor passing. Works for the local case (spice server and client on the same machine) only. Supporting remote too is planned (by feeding the dma-bufs into gpu-assisted video encoder), but not there yet. gl mode is turned off by default, use "-spice gl=on,$otherargs" to enable it.

2016-02-23usb: add pid check at the first of uhci_handle_td()Gonglei1-6/+16
pid can be gotten from uhci device memory in uhci_handle_td(), so the guest can trigger assert qemu if we get an invalid pid. And the uhci spec 2.1.2 tells us The Host Controller sets Host Controller Process Error bit to 1 when it detects a fatal error and indicates that the Host Controller suffered a consistency check failure while processing a Transfer Descriptor. An example of a consistency check failure would be finding an illegal PID field while processing the packet header portion of the TD. When this error occurs, the Host Controller clears the Run/Stop bit in the Command register to prevent further schedule execution. We'd better to set UHCI_STS_HCPERR and kick an interrupt, check the pid value at the first of uhci_handle_td function. https://bugzilla.redhat.com/show_bug.cgi?id=1070027 Signed-off-by: Gonglei <arei.gonglei@huawei.com> Message-id: 1455867238-4720-1-git-send-email-arei.gonglei@huawei.com [ applied minor codestyle fix ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

The relative ordering of "device_del" return value and the "DEVICE_DELETED" QMP event depends on the architecture being tested. On x86 unplugging virtio disks is asynchronous (=qdev_unplug()= → =hotplug_handler_unplug_request()=) while on s390x it is synchronous (=qdev_unplug()= → =hotplug_handler_unplug()=). This leads to the actual output on s39
