X-BeenThere: freebsd-sparc64@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Porting FreeBSD to the Sparc List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 30 Jan 2004 01:05:51 -0000 I figured out part of the Creator-3D issue I think. Apparently there are two things that are called Creator-3D. One is what comes in Ultra-60's/Ultra-80's and is, I think, a PCI card. I haven't pulled the Ultra-60 apart (yet) to verify. The other is what comes in Ultra-10's. The modifications people have been suggesting for getting the Creator-3D to work seem to work just fine on my Ultra-60, not on the Ultra-10. It seems like the thing in the Ultra-10 looks enough like a Creator-3D to fool the kernel into starting to use it, but the kernel hangs very ungracefully (as in turn the machine off and back on) shortly after blanking the screen. I have taken the Ultra-10 apart and the card in that is definitely not a PCI card. Does anyone have information that suggests any of this is wrong? Now... If that is true... There appear to be two separate creator drivers in the source tree. I have not confirmed it by trying to build a kernel for the Ultra-60 that does not include the driver in src/sys/sparc64/creator yet but I think the driver that works with the Ultra-60 is in src/sys/dev/fb/creator.c. Both of those files wind up going into the kernel if you include "creator" and "sc" in the kernel config file. Given the above theory I tried to build a kernel that only had the src/sys/sparc64/creator driver in it. The kernel built just fine (no unresolved symbols, etc) so the drivers do indeed at least appear to be separate. This kernel booted on the Ultra-10 without getting hung but there were no signs of it having found a creator device anywhere either. Does this make sense? If yes does it give anyone new ideas on what to try or is this variant of the Creator-3D just not going to work?
