You could use systemtap or just add a printf to see who/when it is actually
called,
and if you just want to find out statically (browsing the source) grep for
update_area,
you'll find:
playa:qemu alon spice.kvm.v18.ccid.v8.1.based $ git grep -p update_area
hw/qxl-render.c=void qxl_render_update(PCIQXLDevice *qxl)
hw/qxl-render.c: qxl->ssd.worker->update_area(qxl->ssd.worker, 0, &update,
hw/qxl.c=static void ioport_write(void *opaque, uint32_t addr, uint32_t val)
hw/qxl.c: QXLRect update = d->ram->update_area;
hw/qxl.c: d->ssd.worker->update_area(d->ssd.worker,
d->ram->update_surface,
So other then on rendering (qxl_render_update, called from qxl_hw_update or
screendump)
the main path is by io port QXL_IO_UPDATE_AREA from the driver. If you look at
the driver
you can see when that is triggered.
