Yup, at least it's an interesting mobile X11-terminal :D

I actually don't mind my 11" MacBook Air. I used a 12" iBook G4 as my regular laptop before that, which still gets occasional use for presentations and as a portable DVD player.

Sold mine faster than a fsck since it was very annoying, especially the dead-battery and the power-cord sucked a lot as I had to repair it three times. It's definitively the last laptop I want to buy from Apple. But, I want to reverse an old PowerBookG3, replacing the motherboard with a custom fpga board that I am designing during week ends, as well as the VDU unit and the keyboard controller. The chassis is big enough to keep the new electronic-parts, including a couple of big batteries.

Currently the working progress: 26%. It will take a while. At the end it will be a VT100 portable terminal in laptop shape, plus X11 if I will have the time to complete the graphics framebuffer and porting xorg. I am also having problems with the native PAD, I think I will replace it with a PeeeCeee's one since they are usually better hackable.

Also, I am experimenting with a new fpga-vendor: Lattice! My customers want to do business only with Xilinx, so I am completely new to Lattice's 'ICE-x'-stuff. Never used, but as far as I tried I am already impressed by their 'Diamond' toolchain. Very comfortable and friendly!

So, I built a mini-mac cluster, composed by three mac-mini units stacked together in tower shape :D

Two units are PPC-G4, one unit is x86-i2. Lattice Diamond runs on the x86 macmini node. G4-nodes are used to native test PowerPC stuff. I can cross-compile kernels on x86-i2 as well as building and testing PowerPC-stage{1-4} in native way on G4-units.

Damn productive machine!

Hey, sorry for the prolonged reply!

With the help of QEMU, I should be able to have a more recent version of Cinema 4D running on the box, which means I can run the Cycles 4D renderer. Ideally I would like to slap in a graphics card that can run the renderer in the GPU mode (I recon it would be faster then if it was going through the CPU), but along with having enough VRAM to render out something with high poly counts, I also want it to drive the displays in my setup (Apparently having 2 1440p displays and a single 720p Cintiq display takes up 3.5GB of VRAM... who knew?). So ultimately that is the kind of GPU(s) I need in a system...

Introducing the Mac Mega.

Wait, what about the Xserve?

I'm afraid you are out of luck if you go the G5-way. According to Apple's documentation for the PCI-Express G5s, the sum of the VRAMs of all the installed graphics card can't exceed 1GB.

So... 2 Quadros (if you find a way to power the 2nd), or maybe 4 GeForce 6600.
However, a 512MB Quadro can drive 2x1600p displays...

The Xserve is rackable, not stackable. ;)

Well, I guess you could stack them, but the IIci had feetsies and the Mac mini (at least this generation) had a rubber mat. That gets ventilation under the unit and prevents them from slipping and sliding all over the place like a stack of Xserves would.

Quite. I'm pretty satisfied with just the one in this Quad. It can play the G5 version of Prey (id Tech 4) in reduced power mode without much effort. I think I had it set to 1280x1024 in a window or something.

That will be a problem then... Since that won't drive 2 1440p displays and my Cintiq 18SX, along on with storing multiple 4K textures and motion blur while rendering out animations since Cycles (and inherently Cycles 4D) doesn't have an OoC architecture for GPU rendering (which I really it had)! :lol: / :(

I'm not sure what the behavior would be under Linux. Usually Apple's tech notes refer to Mac OS.
If you, or anyone, has got a spare graphics card to test, anything PCI Express not requiring extra power source, I'm happy to test. I can have that + my Quadro and easily exceed 1GB of VRAM.

eh, 1GB, here I am limited to 32MByte of VRAM, to be shared along four MDA chips, since each one needs to drive a VGA channel. Four VGA channels handled by the same video board, but I want to allocated 8Mbyte per channel. Luckily, from the point of view of the kernel, I can have four devname, one for each MDA chip { /dev/fb0, /dev/fb1, /dev/fb2, /dev/fb3 } but, from the point of view of X11 they can be bonded in Xinerama-setup. Awesome, since the final setup just needs a few changes, it's almost already tested, known of being working, and ready. Thanks to Matrox. Good news I have also recently found a PCI_32_mem_only board which really comes with four MDA chips.

All of this for a simple framebuffer with ZERO 2D acceleration! Zero means NO DRI/DRM at all! I have experimented a lot so many troubles with GPU under linux that I wouldn't recommend it, as well I am a bit ... puzzled with your idea of putting an heavy app under Qemu.

That's how we drive progress, right? =)
Paradoxical, given the machines we use, but... =)

No reason other then I like Portal and the defective turrets, and this has been my "goto" name if I plan on using an account longer then me being in the MLP fandom that I am currently in... :lol:
