Could you clarify this information? The code from kernel framebuffer
driver (blizzard.c) suggests that only width should be 4px aligned:
switch (color_mode) {
case OMAPFB_COLOR_YUV420:
/* Embedded window with different color mode */
bpp = 12;
/* X, Y, height must be aligned at 2, width at 4 pixels */
x &= ~1;
y &= ~1;
height = yspan = height & ~1;
width = width & ~3;
break;
Does xserver introduce additional limitations?
