<para>
Drivers must initialize the vertical blanking handling core with a call to
<function>drm_vblank_init</function> in their
<methodname>load</methodname> operation. The function will set the struct
<structname>drm_device</structname>
<structfield>vblank_disable_allowed</structfield> field to 0. This will
keep vertical blanking interrupts enabled permanently until the first mode
set operation, where <structfield>vblank_disable_allowed</structfield> is
set to 1. The reason behind this is not clear. Drivers can set the field
to 1 after <function>calling drm_vblank_init</function> to make vertical
blanking interrupts dynamically managed from the beginning.
<methodname>load</methodname> operation.

Vertical blanking interrupts can be enabled by the DRM core or by drivers
