applehacker Posted January 30, 2009 Share Posted January 30, 2009 Im sure we all have an old laptop with one of these in it. I am curious as to how we can get the Mobility 7500 working with QE. I know CI is not supported period, i just don't see why QE cannot be enabled. It is successfully recognized as an AGP card (AGPGart 2.7.1 installed), but qe is not supported, quartzgl is. Can we use callisto for refresh rates and display size? What other kexts do we need to get qe working? It was working in leopard (modded framebuffer?), why can we not just apply the same concept? If the mobility radeon 7500 kexts are PowerPC only, how come they worked in tiger? Please, lets collaborate and try to get his working like we did in tiger. Here is what I have experimented so far: AGPGart works (Chipset detected, agp detected) Radeontool causes kernel panic Callisto may or may not work. Framebuffer from tiger causes a kernel panic. Any more contributers? Link to comment Share on other sites More sharing options...

jaxparo Posted May 15, 2009 Share Posted May 15, 2009 I think it may be possible? The Radeon 7500 AGP is supported for Leopard in the PowerMac G4 Quicksilver 2002, and I've confirmed that Quartz Extreme does work under Leopard 10.5.7. The Radeon 7500 mobility came in the PowerBook G4 DVI 667 & 800 MHz, which while not supported for Leopard, most likely work, although I haven't confirmed that yet. I don't know enough about the differences between desktop and laptop versions of the same card; or between PPC and PC ROMs, but it would seem likely that if the Radeon 7500 Mac editions work in Leopard there could be an easy way to make the PC versions work? The relevant kexts that are loaded on a Quicksilver Radeon 7500 with QE working under OS 10.5.7 are: 71 0 0x2b479000 0x44000 0x43000 com.apple.ATIRadeon (5.4.4) <70 69 17 12 4 2> 85 1 0x12d91000 0x15000 0x15000 com.apple.driver.ndrv.ATY,Moonraker.0x12d9cb8c (1.0.1f7) the dependencies <70 69 17 12 4 2> are: 70 2 0x2b461000 0x18000 0x17000 com.apple.iokit.IONDRVSupport (1.7.3) <69 17 7 6 5 4> 69 3 0x2b43b000 0x26000 0x25000 com.apple.iokit.IOGraphicsFamily (1.7.3) <17 7 6 5 4> 17 11 0x1f618000 0x14000 0x13000 com.apple.iokit.IOPCIFamily (2.6) <7 6 5 4> 7 19 0x0 0x0 0x0 com.apple.kpi.unsupported (9.7.0) 6 37 0x0 0x0 0x0 com.apple.kpi.mach (9.7.0) 5 42 0x0 0x0 0x0 com.apple.kpi.libkern (9.7.0) 4 40 0x0 0x0 0x0 com.apple.kpi.iokit (9.7.0) What does it take to get this working? There are a ton of old laptops with various Radeon 7500 mobility cards that could really benefit from Quartz Extreme. My Radeon 7500 mobility has no drivers loaded under 10.5.6.

riws Posted May 15, 2009 Share Posted May 15, 2009 ATIRadeon driver for ATi Radeon 7500 is PowerPC only, it wont load with x86 CPU. Link to comment Share on other sites More sharing options...
bamdad Posted December 28, 2009 Share Posted December 28, 2009 ATIRadeon driver for ATi Radeon 7500 is PowerPC only, it wont load with x86 CPU. does anybody know if this driver is darwin/open source? if so, we could download it from somewhere and recompile it for x86. i'd do it, even if i'm not the best in c, i'd like to give it a shot.
