XBMC on Tegra2 development: Porting XBMC for Linux to NVIDIA Tegra 2 ARM SoC platform

Starting a thread for XBMC on Tegra2 development to stop hi-jacking McGeagh's thread

This is for Tegra2 specific discussion only please. And remember Tegra2 Linux SDK is still under NDA so please refrain from asking or discussing details regarding the Tegra2 Linux SDK until it is released.

The same XBMC development discussion on the nvidia forum:

Just curious, how far along are with getting it run on tegra 2 ?
Can the cpu handle it alone or due you think it still needs hardware accelerated linux drivers ?

Remember video display is not the same as video decode so your question about the need for hardware accelerated linux drivers is not specific enough.

XBMC requires GPU acceleration for scaling/texture display handling on OSX, Linux and Windows platforms . Software display handling is dog slow on these platforms already so Tegra2 is no different. OSX and Linux use OpenGL, Windows uses either OpenGL or DX. For Tegra2, it's OpenGL/ES.

Tegra2 is similar to AppleTV, maybe a bit more ponies as it's a dual-core 1GHz CPU. Again don't compare CPU speed across processor archs, it does not scale and depends on much, much more than just CPU clock. I base my comparison on feel of the ubuntu desktop and compile times of XBMC. Tegra2 seems snapper on desktop and compile is much faster.

For video decoding, Tegra2 offers an OpenMax API for hardware acceleration. Claimed to handle 1080p, we will see. With software decode, again basing this on difference to Linux on AppleTV (without crystalhd), maybe main profile 720p. This depends heavily on hardware floating point and fact that Tegra2 does NOT contain a NEON floating point unit.

Right now, XBMC is up and running but no display because of goofy SDL getting in the way. No OpenMax work has been done yet. Ask me again next week.

Any just to make it clear, if anyone asks when it will be ready, they get poked in the eye with a sharp stick.

when will it be ready?


BTW I love the confusing post saying oh its totally different...... but wait it does this instead

How does it compare to atom 330 in terms of compile time and look and feel of Ubuntu ?

atom 330 >> tegra2 >> appletv.

How about power consumption of the tegra 2 systems?

don't know, I'm unconcerned with power consumption at the current time, plus this is a dev kit and not a finished product. Power consumption will vary depending on target options of the platform design.

Do you think once it is finished product, NVIDIA will lock consumers out from loading Ubuntu on it ?
