Or I'm wrong?
Are you sure you even need to write your own 3D drivers? The DRM, i.e. things happening on a kernel level, are sure to require their own adaptation for OpenSolaris (btw, we recently talked about this on the #radeon IRC channel). The userspace driver, on the other hand, should require only minimal modifications, at least as long as you also use X.org and DRI/DRI2 as the X- level protocol. With that in mind, your best bet is just to reuse the *existing* drivers for hardware. Believe me, if you really want to go the not-invented-here route and write your own driver, you will always be lagging behind, no matter whether you use Gallium or not. On the other hand, it seems to me that cross-platform drivers are easier to do with Gallium than in the old model, so if both a Gallium and an old driver exist for the hardware you have in mind, it's probably not a bad idea to concentrate on the Gallium driver. > Also, I would like to say that I'm in the team with Matrin and Edward, > and we try to develop some ATI drivers.

Are you working on DRM parts or on the 3D userspace parts? cu, Nicolai ------------------------------------------------------------------------------ Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!
