However, when tiled -+ * it does it a little differently, since one walks addresses not just in the -+ * X direction but also Y. So, along with alternating channels when bit -+ * 6 of the address flips, it also alternates when other bits flip -- Bits 9 -+ * (every 512 bytes, an X tile scanline) and 10 (every two X tile scanlines) -+ * are common to both the 915 and 965-class hardware. -+ * -+ * The CPU also sometimes XORs in higher bits as well, to improve -+ * bandwidth doing strided access like we do so frequently in graphics.

The result -+ * is that the CPU is XORing in either bit 11 or bit 17 to bit 6 of its address -+ * decode. -+ * -+ * All of this bit 6 XORing has an effect on our memory management, -+ * as we need to make sure that the 3d driver can correctly address object -+ * contents. -+ * -+ * If we don't have interleaved memory, all tiling is safe and no swizzling is -+ * required. -+ * -+ * When bit 17 is XORed in, we simply refuse to tile at all.
