2016-09-28ui/vnc-enc-tight: remove switch and have single returnAlex Bennée
When enabling the sanitizer build it will complain about control reaching a non-void function. Normally the compiler should detect that there is only one possible exit given a static VNC_SERVER_FB_BYTES. As we always expect a static VNC_SERVER_FB_BYTES I've added a compile time assert and just called the sub-function directly.

2016-09-28spice/gl: render DisplaySurface via openglGerd Hoffmann
This switches over spice (in opengl mode) to render DisplaySurface updates into a opengl texture, using the helper functions in ui/console-gl.c. With this patch applied spice (with gl=on) will stop using qxl rendering ops, it will use dma-buf passing all the time, i.e. for bios/bootloader (before virtio-gpu driver is loaded) too. This should improve performance even using spice (with gl=on) with non-accelerated stdvga because we stop squeezing all display updates through a unix/tcp socket and basically using a shared memory transport instead.

2016-09-28console: skip same-size resizeMarc-André Lureau
virtio-gpu does a set-scanout at each frame (it might be a driver regression). qemu_console_resize() recreate a surface even if the size didn't change, and this shows up in profiling reports because the surface is cleared. With this patch, I get a +15-20% glmark2 improvement.

2016-09-27qdisk - hw/block/xen_disk: grant copy implementationPaulina Szubarczyk
Copy data operated on during request from/to local buffers to/from the grant references. Before grant copy operation local buffers must be allocated what is done by calling ioreq_init_copy_buffers. For the 'read' operation, first, the qemu device invokes the read operation on local buffers and on the completion grant copy is called and buffers are freed. For the 'write' operation grant copy is performed before invoking write by qemu device. A new value 'feature_grant_copy' is added to recognize when the grant copy operation is supported by a guest.

2016-09-27target-i386: Don't try to enable PT State xsave componentEduardo Habkost
The code that calculates the set of supported XSAVE components on CPUID looks at ext_save_areas to find out which components should be enabled. However, if there are zeroed entries in the ext_save_areas array, the ((env->features[esa->feature] & esa->bits) == esa->bits) check will always succeed and QEMU will unconditionally try to enable the component. Luckily this never caused any problems because the only missing entry in ext_save_areas is the PT State component (bit 8), and KVM currently doesn't support it (so it was cleared on ena_mask). But the code was still incorrect and would break if KVM starts returning CPUID[EAX=0xD,ECX=0].EAX[bit 8] as supported on GET_SUPPORTED_CPUID. Fix the problem by changing the code to not enable a XSAVE component if ExtSaveArea::bits is zero.

This was already done for CPUID[7].EBX, and is now made generic for all CPUID feature flags.
