[Linux-fbdev-devel] [PATCH] soft accels.
|
From: James S. <jsi...@tr...> - 2002-03-12 00:23:07
|
This code provides software accels to replace all the fbcon-cfb* stuff.
Gradually the fbdev drivers can be ported over to it. It is against
2.5.5-dj3. Please apply the patch.

+ * Generic BitBLT function for frame buffer with packed pixels of any depth.
+ *
+ * Copyright (C) June 1999 James Simmons

+ * This file is subject to the terms and conditions of the GNU General Public
+ * License. See the file COPYING in the main directory of this archive for
+ * more details.
+ *
+ * NOTES:
+ *
+ * This function copys a image from system memory to video memory. The
+ * image can be a bitmap where each 0 represents the background color and
+ * each 1 represents the foreground color. Great for font handling. It can
+ * also be a color image. This is determined by image_depth. The color image
+ * must be laid out exactly in the same format as the framebuffer. Yes I know
+ * their are cards with hardware that coverts images of various depths to the
+ * framebuffer depth. But not every card has this. All images must be rounded
+ * up to the nearest byte. For example a bitmap 12 bits wide must be two
+ * bytes width.
+ *
+ * FIXME
+ * The code for 24 bit is horrible. It copies byte by byte size instead of
+ * longs like the other sizes. Needs to be optimized.
+ *
+ * Also need to add code to deal with cards endians that are different than
+ * the native cpu endians. I also need to deal with MSB position in the word.
