Good news for the driver stack

Tue Jun 17, 2014 5:36 pm

This, http://anholt.livejournal.com/44239.html, is very good news for the Raspberry Pi.

It still has as far as I'm aware although probably no one want's to buy them out yet :)

Very early days for the buyout so far.

Not had any contact Eric yet - he only started Monday, but he works from home, in the USA....and the 3D team is here in the Cambridge office in the UK....so probably won't come across him in the corridor! If we had any corridors.

Just out of curiosity what does he mean by "kernel DRM driver" and why would his work be considered important for the Pi??

From what I read, Eric Anholt is going to write the three boxes in the second column in this, http://en.wikipedia.org/wiki/Direct_Ren ... k_2013.svg, picture. There is a lot of linux stuff that is going to profit from those boxes. Plus, the fact that it is going to be open source will make the platform even more attractive for a lot of people.
It should be easier to get hardware acceleration for Android although the CPU is never going to make that very fast.

If I understood correctly what he'll be doing (porting the OpenGL stack to run on the ARM core instead of the VPU), isn't that going to slow things down?

Some parts will run on the ARM core, but not in such a way that it would slow things down.

This doesn't means there's still hope for Android.
This [ https://github.com/trevd?tab=repositories ] means there's still hope for Android 8-) and it's progressing quite nicely now that I'm finally beginning to understand how everything fits together

However If Eric does the full job on this, i.e dri and gallium drivers plus a full libdrm for the videocore then that would leave only the gralloc module remaining to complete an Android compatible drm/kms graphics stack but regardless it's always been possible using the userland sources.

Typical isn't it? Just like buses. You wait 3 years for a working Android and then 2 possibly come along at once :D

thanks
