accel_vga

Description

Accelerated Super VGA device implementing the Bochs VBE protocol. Supports all reasonable VBE modes that fit into the 16 MiB display memory, the largest being 2560x1600x32. Modes outside of the configured display resolution, changeable with the display-resolution command, will not be reported by the VGA BIOS when queried for available modes.

Interfaces Implemented

conf_object, log_object, accel_vga_v2, image_snoop, pcie_device

Notifiers

cell-change: Notifier that is triggered after the object's cell was changed.
object-delete: Notifier that is triggered just before Simics object is deleted.
queue-change: Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.
state-change: Notifier on potential DML state change
