Just to say that i'm really happy with radeon/radeonhd and all the development about this project and encourage/thank people in charge of it.
It just misses complete 3D implementation and everybody will switch to this driver, if it's not ever done.
GO ON !!!
Just one thing : do you know a graphical way to configure the xorg.conf with opensource driver (Something like ccmde) cause i havent seen any info about that on radeon/radeonhd website.
Yeah, redeon/radeonhd are awesome. Question thought: Does the driver use the correct amount of vRAM for you guys? Both drivers correctly detect all the memory (512MB) but then I get a message about the driver only being able to use half, as well as radeonhd detecting the memory as 128bit (should be 256bit). None of this really matters right now seeing as there is no need for performance, but I wonder if that's a bug or simply a temporary limitation.
I also wonder if the card is even able to use 1GB of video RAM....
Edit: I have an HD3650 BTW.

Same thing for me :
Bibi.Code:(II) RADEONHD(0): The detected amount of videoram exceeds the PCI BAR aperture. (II) RADEONHD(0): Using only 262144kB of the total 524288kB. (--) RADEONHD(0): VideoRAM: 262144 kByte

The max pci aperture size is 256 MB, so that is the largest amount of vram that can be accessed by CPU. The GPU can address the entire amount of vram. We currently limit the amount of vram to 256 MB since we lack a proper memory manager to provide access to buffers in GPU-only space to the CPU. This is being addressed in the new kernel modesetting, ttm radeon drm.
