This patch solving problem on my N900.
Hi, I found a problem why code (without) this patch garbage display
output. I played with code in function video_draw_cursor and every
time when I tried to only read what is stored in *dest, on n900
dispaly was show some random white or blue pixel. This code not
working on n900:
static u8 foo;
...
for (y = firsty; y < lasty; y += VIDEO_LINE_LEN) {
for (x = firstx; x < lastx; x++) {
u8 *dest = (u8 *)(video_fb_address) + x + y;
foo = *dest;
*dest = 0xff;
}
}
But if I commented assign foo = *dest; everything is OK.
So I think that reading memory of framebuffer on n900 does not working
(it also write something somewhere...) What do you think, where can be
problem?
