Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

24 | * voffset - framebuffer offset in MiB from aperture start address. In order for | ||
25 | * the driver to work with X, we must try to use memory holes left untouched by X. The | ||
26 | * following table lists where X's different surfaces start at. | ||
27 | * | ||
28 | * --------------------------------------------- | ||
29 | * : : 64 MiB : 32 MiB : | ||
30 | * ---------------------------------------------- | ||
31 | * : FrontBuffer : 0 : 0 : | ||
32 | * : DepthBuffer : 48 : 16 : | ||
33 | * : BackBuffer : 56 : 24 : | ||
34 | * ---------------------------------------------- | ||
35 | * | ||
36 | * So for chipsets with 64 MiB Aperture sizes, 32 MiB for v_offset is okay, allowing up to | ||
37 | * 15 + 1 MiB of Framebuffer memory. For 32 MiB Aperture sizes, a v_offset of 8 MiB should | ||
38 | * work, allowing 7 + 1 MiB of Framebuffer memory. | ||
39 | * Note, the size of the hole may change depending on how much memory you allocate to X, | ||
40 | * and how the memory is split up between these surfaces. | ||
41 | * | ||
42 | * Note: Anytime the DepthBuffer or FrontBuffer is overlapped, X would still run but with | ||
43 | * DRI disabled. But if the Frontbuffer is overlapped, X will fail to load. | ||
44 | * | ||
45 | * Experiment with v_offset to find out which works best for you. | ||
