MODE_XOR?
From: David Muse ####@####.#### Date: 23 Oct 2002 19:34:09 -0000 Message-Id: <20021023153629.72178529.dmuse@4accesscommunications.com> While hacking together a 4bpp pxa210/hantronix lcd framebuffer subdriver, I noticed a MODE_XOR flag. What does it do? It it something that can be set at runtime? My driver doesn't appear to be configured in that mode at any time, is it safe to remove the check for it?
