To prevent exessive allocations the bounce buffers are allocated once and afterwards re-used. The DMA buffers are provided by an range allocator whose backing store increases in 4 MiB chunks. The range allocator might not merge the ranges as those chunks are not necessarily allocated continously. Allocations larger than the static chunk size are therefor treated as error. |

VirtualBox configuration options ================================ The configuration requires an attribute named vbox_file with the name of the vbox configuration to be used (.vbox). <config vbox_file="file.vbox"> XHCI controller ~~~~~~~~~~~~~~~ The virtual XHCI controller can be enabled with the following configuration option: <config xhci="yes"> CapsLock ~~~~~~~~ Per default CapsLock key events are send unmodified to guest operating systems. As guest and host state may diverge, the event filter optionally reports the capslock state as ROM, which can be monitored by VirtualBox if configured like follows. <config capslock="rom"> VirtualBox requests a "capslock" ROM, which is interpreted as XML. The top-level node attribute 'enabled' is expected boolean and represents the CapsLock state. If ROM and VM-internal CapsLock state differ, the VMM sends aritifical CapsLock key events to the VM. In this mode, incoming KEY_CAPSLOCK input events a dropped and not sent to the guest to prevent the state divergence.
