Running The NVIDIA Binary Blob On The Tegra K1 ARM SoC

[Milache.Kumpel]

Wow, thanks, I spent hours working on this, had no idea the drivers were the problem. Still very new to Linux, and Ubuntu. Thanks! Working like a champ now.
PS After you got the new board up and running, did you re-flash with the latest Ubuntu using the cuda toolkit installer? Im afraid to break the install again. Thanks, Milache.

The last I looked, the only discrete card options were Nvidia. I suspect ATI support would be comparatively more expensive.

Ahh, I didn't catch the "discrete" part. thanks for the clarification.

It's a work in progress: http://lists.freedesktop.org/archive...il/058541.html

right, I am aware of that work.. I was hoping that someone w/ one of these boards could check if they are using nouveau kernel module already.

I'd assume some patches needed here and there in userspace too, since currently userspace figures out what to do based on pci-id's. And now we have separate gpu (nouveau) vs display (tegradrm) drivers. Etc. I'm sure *someone* has nouveau working on the thing already, but not don't think everything needed is upstream and released yet, etc.

I would expect that nouveau will be an option eventually. You might need to wait until some nouveau dev gets their hands one one of these boards.

Is there anything in the way of open-source graphics drivers for this board?
I thought there were earlier articles about Tegra nouveau drivers

False, as proven by Phoronix again and again.

I am greatful that AMD seems to be improving their Linux performance. That is the first benchmark I have seen where catalyst performs better on Linux. And I look at a lot of benchmarks.

However, that Catalyst driver is beta. I strongly suspect that if we look over the various benchmarks over the past year, we will see a consistent deficit of catalyst drivers vs. Nvidia offerings on Linux and their windows counterparts.

pick a discrete card...

That's ironic, most of the options on the System76 site for Desktop and Laptops default to Intel graphics.

VDPAU?

Can you tell me: Does this board have VDPAU support with the proprietary driver?

Thanks,

By comparison, AMD's Catalyst drivers range from mediocre to "I-can't-believe-you-shipped-that-steaming-pile" in spec compliance, performance and reliability.

Personally I AMD Cataclysm hater for a long time, but it's always were less permissive from point of OpenGL/GLSL spec compatibility. It's Nvidia who allow compile any crap within GLSL shaders and then this crap don't work with any other driver which follow spec more strictly.

About real spec implementation it's also open question too and nobody just using latest OpenGL core profile so we can't actually test it properly. If you make some real OpenGL 4.3/4.4 application and then test it with old Nvidia drivers that state this version support your app most likely will fail or crash. So I suppose big part of Nvidia's "first day" GL/GLSL compatibility it's nothing more than just marketing bullshit.

At their best, Catalyst seems to get 75% of their Windows drivers.

Lie. AMD had crappy OpenGL performance for long time on both drivers, but Windows/Linux performance game never were that big. E.g Unigine Benchmarks perform for 10-15% better in D3D11 mode for long time, but not situation improved.

Situation with new kernels/X compatibility still really bad with AMD for me, but if you have Ubuntu 12.04 it's will have 95%+ of Windows driver performance.

If everyone had their shit together as well as nVidia and their dev kit on Linux, I suspect Google wouldn't have much excuse for disabling video HW acceleration by default on Chrome.

Google have long history as company which have no interest in their software product support on Linux.

I suppose they didn't release Google Drive client due to graphics drivers problems too.
