2016-02-23spice: add opengl/virgl/dmabuf supportGerd Hoffmann1-3/+107
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.

2015-09-21spice: surface switch fast path requires same format too.Gerd Hoffmann1-1/+2
Commit "555e72f spice: rework mirror allocation, add no-resize fast path" adds a fast path for surface switches which does't go through the full primary surface destroy and re-recreation in case the new surface is identical to the old one (page-flip). It checks the size only though, but the format must be identical too. This patch adds the format check. Commit "0002a51 ui/spice: Support shared surface for most pixman formats" increases the chance to actually trigger this. https://bugzilla.redhat.com/show_bug.cgi?id=1247479 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2014-12-16spice: rework mirror allocation, add no-resize fast pathGerd Hoffmann1-7/+26
Add fast path to qemu_spice_display_switch in case old and new displaysurface have identical size (happens with display panning and page flipping). We just swap the backing store then and don't go through the whole process of deleting and creating the primary surface. To simplify the code a bit move mirror surface allocation to qemu_spice_display_switch(). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2014-12-16spice: use bottom half instead of refresh timer for cursor updatesGerd Hoffmann1-2/+10
Calling directly doesn't work due to the qxl-render code running in spice server thread context. Meanwhile bottom half scheduling is thread-safe though, so we can use that to kick a cursor update in main i/o thread context.

2014-09-05spice: make sure we don't overflow ssd->bufGerd Hoffmann1-5/+15
Related spice-only bug. We have a fixed 16 MB buffer here, being presented to the spice-server as qxl video memory in case spice is used with a non-qxl card. It's also used with qxl in vga mode. When using display resolutions requiring more than 16 MB of memory we are going to overflow that buffer. In theory the guest can write, indirectly via spice-server. The spice-server clears the memory after setting a new video mode though, triggering a segfault in the overflow case, so qemu crashes before the guest has a chance to do something evil. Fix that by switching to dynamic allocation for the buffer.

2013-10-17spice: fix multihead supportGerd Hoffmann1-3/+20
This patch fixes spice display initialization to handle multihead properly. spice-core now keeps track of which QemuConsole has a spice display channel attached to it and which has not. It also manages display channel ids. spice-display looks at all QemuConsoles and will pick up any graphic console not yet bound to a spice channel (which in practice are all non-qxl graphic devices). Result is that (a) you'll get a spice client window for each graphical device now (first only without this patch), and (b) mixing qxl and non-qxl vga cards works properly.

2013-04-16console: allow pinning displaychangelisteners to consolesGerd Hoffmann1-5/+6
DisplayChangeListener gets a new QemuConsole field, which can be set to non-NULL before registering. This will pin the QemuConsole, so that particular DisplayChangeListener will not follow console switches. spice+gtk (which don't support text console input anyway) are switched over to be pinned to console 0, which usually is the graphical display.
