From 55d7bfe2293c854a1ddb54ca00672b7b8e3eebbb Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Sat, 13 Sep 2014 10:44:07 +0100 Subject: tcx: Implement hardware acceleration The S24/TCX framebuffer is a mildly accelerated video card with blitter, stippler and hardware cursor. * Solaris and NetBSD 6.x use all the hardware acceleration features * The Xorg driver (used by Linux) can use the hardware cursor only This patch implements hardware acceleration in both 8 bit and 24 bit modes. It is based on the NetBSD driver sources and from tests with Solaris.
