2015-01-22spice: fix coverity reported defect in display codeGerd Hoffmann1-3/+3
Report: 1. Condition surface, taking false branch 406 if (surface && ssd->surface && 407 surface_width(surface) == pixman_image_get_width(ssd->surface) && 408 surface_height(surface) == pixman_image_get_height(ssd->surface)) { 409 /* no-resize fast path: just swap backing store */ ... 10. alias_transfer: Assigning: ssd->ds = surface. 440 ssd->ds = surface; 11. var_deref_op: Dereferencing null pointer ssd->ds. CID 1264334 (#1 of 1): Dereference after null check (FORWARD_NULL) 441 ssd->surface = pixman_image_ref(ssd->ds->image); Fix: Move code block dereferencing ssd->ds into the already existing if (ssd->ds) { ... } block.

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.

2013-04-16console: rename vga_hw_*, add QemuConsole paramGerd Hoffmann1-1/+1
Add QemuConsole parameter to vga_hw_*, so the interface allows to update non-active consoles (the actual code can't handle this yet, see next patch). Passing NULL is allowed and updates the active console, like the functions do today. While touching all vga_hw_* calls anyway rename that to the functions to hardware-neutral graphics_hw_* Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Stop abusing displaysurface fields for text mode displays. (bpp = 0, width = cols, height = lines). Add flags to displaystate indicating whenever text mode display (curses) or gfx mode displays (sdl, vnc, ...) are present. Add separate displaychangelistener callbacks for text / gfx mode resize & updates. This allows to enable gfx and txt diplays at the same time and also paves the way for more cleanups in the future.

2012-10-08spice: raise requirement to 0.12Gerd Hoffmann1-38/+0
With the next qemu version (1.3) we are going to bump the qxl device revision to 4. The new features available require a recent spice-server version, so raise up the bar. Otherwise we would end up with different qxl revisions depending on the spice-server version installed, which would be a major PITA when it comes to compat properties.

2012-03-22ui/spice-display: use uintptr_t when casting qxl physical addressesAlon Levy1-5/+5
The current intptr_t casts are a problem when the address's highest bit is 1, and it is cast to a intptr_t and then to uint64_t, such as at: surface.mem = (intptr_t)ssd->buf; This causes the sign bit to be extended which causes a wrong address to be passed on to spice, which then complains when it gets the wrong slot_id number, since the slot_id is taken from the higher bits. The assertion happens early - during the first primary surface creation. This fixes running "-vga qxl -spice" with 32 bit compiled qemu-system-i386.
