class DisplayFeatureControl
Defined at line 247 of file ../../src/graphics/display/drivers/framebuffer-bochs-display/bochs-vbe-registers.h
VBE_DISPI_INDEX_ENABLE
Enables / disables features of the display engine.
Supported by all API versions.
This register has bits that are reserved but not MBZ (must be zero). So, it
can only be safely updated via read-modify-write operations.

template <, >typename SelfType::ValueType read_display_capabilities ()VBE_DISPI_GETCAPS
If true, reading the `DisplayHorizontalResolution`,
`DisplayVerticalResolution`, and `DisplayBitsPerPixel` registers returns
the emulator's GUI capability.
Otherwise, reading these registers returns the current values set by the
driver.
