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. This ++ * is called "Channel XOR Randomization" in the MCH documentation. 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. Bit ++ * 17 is not just a page offset, so as we page an objet out and back in, ++ * individual pages in it will have different bit 17 addresses, resulting in ++ * each 64 bytes being swapped with its neighbor! ++ * ++ * Otherwise, if interleaved, we have to tell the 3d driver what the address ++ * swizzling it needs to do is, since it's writing with the CPU to the pages ++ * (bit 6 and potentially bit 11 XORed in), and the GPU is reading from the ++ * pages (bit 6, 9, and 10 XORed in), resulting in a cumulative bit swizzling ++ * required by the CPU of XORing in bit 6, 9, 10, and potentially 11, in order ++ * to match what the GPU expects. ++ */ ++ ++/** ++ * Detects bit 6 swizzling of address lookup between IGD access and CPU ++ * access through main memory. ++ */ ++void ++i915_gem_detect_bit_6_swizzle(struct drm_device *dev) ++{ ++ drm_i915_private_t *dev_priv = dev->dev_private; ++ uint32_t swizzle_x = I915_BIT_6_SWIZZLE_UNKNOWN; ++ uint32_t swizzle_y = I915_BIT_6_SWIZZLE_UNKNOWN; ++ ++ if (!IS_I9XX(dev)) { ++ /* As far as we know, the 865 doesn't have these bit 6 ++ * swizzling issues. ++ */ ++ swizzle_x = I915_BIT_6_SWIZZLE_NONE; ++ swizzle_y = I915_BIT_6_SWIZZLE_NONE; ++ } else if (!IS_I965G(dev) || IS_I965GM(dev)) { ++ uint32_t dcc; ++ ++ /* On 915-945 and GM965, channel interleave by the CPU is ++ * determined by DCC.
