• Patch 5/7
    
    This patch changes the graphical_console_init function to return an
    allocated DisplayState instead of a QEMUConsole.
    
    This patch contains just the graphical_console_init change and few other
    modifications mainly in console.c and vl.c.
    It was necessary to move the display frontends (e.g. sdl and vnc)
    initialization after machine->init in vl.c.
    
    This patch does *not* include any required changes to any device, these
    changes come with the following patches.
    
    Patch 6/7
    
    This patch changes the QEMUMachine init functions not to take a
    DisplayState as an argument because is not needed any more;
    
    In few places the graphic hardware initialization function was called
    only if DisplayState was not NULL, now they are always called.
    Apart from these cases, the rest are all mechanical substitutions.
    
    Patch 7/7
    
    This patch updates the graphic device code to use the new
    graphical_console_init function.
    
    As for the previous patch, in few places graphical_console_init was called
    only if DisplayState was not NULL, now it is always called.
    Apart from these cases, the rest are all mechanical substitutions.

  • This sets a default PCI subsystem ID for all emulated PCI devices.  PCI
    specs require this, so do it.
    
    In many cases it is enougth to know the PCI ID to handle a device
    correctly.  Sometimes a device driver must identify the exact piece of
    hardware (via PCI Subsystem ID) though.
    
    What does this patch to qemu devices:
    
    Right now the emulated PCI devices have no PCI subsystem ID, only the
    PCI ID.  The discussed patch sets a default PCI subsystem ID for all
    emulated devices.  Which will make the qemu devices look pretty much
    like in the laptop case: all PCI subsystem IDs will point to qemu by
    default.
    
    If a driver emulates a very specific piece of hardware where it has to
    emulate more than just the PCI chip, it can overwrite the PCI subsystem
    ID without problems.  The es1370 driver does that for example.
