# cat /sys/kernel/debug/dri/0/i915_swizzle_info
bit6 swizzle for X-tiling = bit9/bit10
bit6 swizzle for Y-tiling = bit9

DDC2 = 0x00200020

L-shaped memory detected
(1)* xf86 git + kernel patch (<a href="show_bug.cgi?id=90725#c22">comment 22</a> only) -> kdm screen is ugly (I didn't
test further)
(2)* xf86 git with patch for wc_mmap (<a href="show_bug.cgi?id=90725#c11">comment 11</a>) + kernel patch (<a href="show_bug.cgi?id=90725#c22">comment 22</a>
only) -> kdm ok, swapping ok, but at some time I still have display issues, I
guess when a program whose memory was put to swap space
(3)* xf86 git with patch for detiling (<a href="show_bug.cgi?id=90725#c11">comment 11</a>) + kernel patch (<a href="show_bug.cgi?id=90725#c22">comment 22</a>
only) -> kdm ok, swapping ok, no problem faced at any time
I'll stay with (3) for some time to see how it behaves</pre>
