From 60b59beafba875aef6d378078bce0baf2287ae14 Mon Sep 17 00:00:00 2001 From: Jaya Kumar Date: Tue, 8 May 2007 00:37:37 -0700 Subject: fbdev: mm: Deferred IO support This implements deferred IO support in fbdev. Deferred IO is a way to delay and repurpose IO. This implementation is done using mm's page_mkwrite and page_mkclean hooks in order to detect, delay and then rewrite IO. This functionality is used by hecubafb. [adaplas] This is useful for graphics hardware with no directly addressable/mappable framebuffer. Implementing this will allow the "framebuffer" to be accesible from user space via mmap().
