2013-04-16xen: re-enable refresh interval reporting for xenfbGerd Hoffmann
xenfb informs the guest about the gui refresh interval so it can avoid pointless work. That logic was temporarely disabled for the DisplayState reorganization. Restore it now, with a proper interface for it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: gui timer fixesGerd Hoffmann
Make gui update rate adaption code in gui_update() actually work. Sprinkle in a tracepoint so you can see the code at work. Remove the update rate adaption code in vnc and make vnc simply use the generic bits instead. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: add GraphicHwOpsGerd Hoffmann
Pass a single GraphicHwOps struct pointer to graphic_console_init, instead of a bunch of function pointers. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: make DisplayState private to console.cGerd Hoffmann
With gui_* being moved to console.c nobody outside console.c needs access to DisplayState fields any more. Make the struct private. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: move gui_update+gui_setup_refresh from vl.c into console.cGerd Hoffmann
Pure code motion, no functional changes. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: zap g_width + g_heightGerd Hoffmann
We have a surface per QemuConsole now, so there is no need to keep track of the QemuConsole size any more as we can query the surface size directly at any time. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: simplify screendumpGerd Hoffmann
Screendumps are alot simpler as we can update non-active QemuConsoles now. So we only need to update the QemuConsole we want write out, then dump the DisplaySurface content into a ppm file. Done. No console switching needed. No special support code in the gfx card emulation needed. Zap it all. Also move ppm_save out of the vga code and next to the qmp_screendump function. For now screen dumping is limited to console #0 (like it used to be), even though it is dead simple to extend it to other consoles. I wanna finish the console cleanup before setting new qapi interfaces into stone. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Igor Mitsyanko <i.mitsyanko@gmail.com>
2013-04-16console: give each QemuConsole its own DisplaySurfaceGerd Hoffmann
Go away from the global DisplaySurface, give one to each QemuConsole instead. With this patch applied it is possible to call graphics_hw_* functions with qemu consoles which are not the current foreground console. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2013-04-16console: rename vga_hw_*, add QemuConsole paramGerd Hoffmann
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>
2013-04-16console: displaystate init revampGerd Hoffmann
We have only one DisplayState, so there is no need for the "next" linking, rip it. Also consolidate all displaystate initialization into init_displaystate(). This function is called by vl.c after creating the devices (and thus all QemuConsoles) and before initializing DisplayChangeListensers (aka gtk/sdl/vnc/spice ui).

2013-04-16hw/vmware_vga.c: various vmware vga fixes.Gerd Hoffmann
Hardcode depth to 32 bpp. It effectively was that way before because that is the default surface depth, this just makes it explicit in the code. Rename depth to new_depth to make it consistent with the new_width + new_height names. In theory we can make new_depth changeable (i.e. allow the guest to fill in -- say -- 16 there). In practice the guests don't try, the X-Server refuses to start if you ask it to use 16bpp depth (via DefaultDepth in the Screen section). Always return the correct rmask+gmask+bmask values for the given new_depth. Fix mode setting to also verify at new_depth to make sure we have a correct DisplaySurface, even if the current video mode happes to be 16bpp (set by vgabios via bochs vbe interface). While being at it switch over to use qemu_create_displaysurface_from, so the surface is backed by guest-visible video memory and we save a memcpy. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-04-16exynos4210_fimd.c: fix display resize bug introduced after console revampIgor Mitsyanko
In exynos4210 display update function, we were acquiring DisplaySurface pointer before calling screen resize function, not paying attention that resize procedure can replace current DisplaySurface with newly allocated one. Right thing to do is to initialize DisplaySurface AFTER a call to resize function. Signed-off-by: Igor Mitsyanko <i.mitsyanko@gmail.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-04-15qdev: Fix QOM unrealize behaviorAndreas Färber
Since commit 249d41720b7dfbb5951b430b9eefdbee7464f515 (qdev: Prepare "realized" property) setting realized = true would register the device's VMStateDescription, but realized = false would not unregister it. Fix that. Moving the code from unparenting also revealed that we were calling DeviceClass::init through DeviceClass::realize as interim solution but DeviceClass::exit still at unparenting time with a realized check. Make this symmetrical by implementing DeviceClass::unrealize to call it, while we're setting realized = false in the unparenting path. The only other unrealize user is mac_nvram, which can safely override it. Thus, mark DeviceClass::exit as obsolete, new devices should implement DeviceClass::unrealize instead.

2013-04-15Add -f FMT / --format FMT arg to qemu-nbdDaniel P. Berrange
Currently the qemu-nbd program will auto-detect the format of any disk it is given. This behaviour is known to be insecure. For example, if qemu-nbd initially exposes a 'raw' file to an unprivileged app, and that app runs 'qemu-img create -f qcow2 -o backing_file=/etc/shadow /dev/nbd0' then the next time the app is started, the qemu-nbd will now detect it as a 'qcow2' file and expose /etc/shadow to the unprivileged app. The only way to avoid this is to explicitly tell qemu-nbd what disk format to use on the command line, completely disabling auto-detection. This patch adds a '-f' / '--format' arg for this purpose, mirroring what is already available via qemu-img and qemu commands. qemu-nbd --format raw -p 9000 evil.img will now always use raw, regardless of what format 'evil.img' looks like it contains Signed-off-by: Daniel P.
