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!

/*

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