[PATCH 3/3] Maple bus support for the Sega Dreamcast - consequential change to pvr2 driver

From: Adrian McMenamin
Date: Sun Sep 09 2007 - 13:06:56 EST


Make the VBLANK interrupt shareable.

This is the third time I have posted this patch. This is required to
allow the Maple bus driver to work (Maple hardware is synced with the
VBLANK interrupt).
