From: "Alexander N. Kabaev" To: freebsd-multimedia@freebsd.org Subject: Utah-glx, G400, AGP and AMD 751 Sender: owner-freebsd-multimedia@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org While we are here, does anyone have success running Utah-GLX with AMD Irongate AGP driver enabled? Everytime I am trying to start the server, DMA times out in exactly the same way as Karel J. Bosschaart describes. I tried to go over AMD 751 datasheet using Linux driver source for the reference and indeed our implementation seems rather broken. I have patches which bring AMD 751 driver closer to it's Linux counterpart and configuration registers dumps taken on Linux and FreeBSD right after the system startup are now identical, testgart runs just fine every time, etc. Unfortunately, these patches still do not allow Utah-GLX to run successfully. At the moment I am pretty much out of ideas on what to try next. ---------------------------------- E-Mail: Alexander N.
