If you want acceleration you get a binary blob if you're lucky. Mostly you're just SOL. There are hints that things are moving slowly towards more openness, but that's about it. It's not much better with embedded DSPs, though Ti seem to have a reasonably open interface. Do you know of a better alternative? To be honest, I was not aware about this. I thought, the lack of specifications of Glamo chip is only a special case of the available embedded GPUs. Quite the reverse - it's a special case that Openmoko managed to get docs that can be released to community devs for an open driver at all, even if they do have to sign an NDA. As a result it's got some of the best open support out there for a mobile GPU. That it doesn't work very well with a 640x480 screen is another matter entirely ;-) However, a possible (but more complex) alternative would be to avoid completely the existing proprietary GPU/DSP chips and make an FPGA based phone instead. Then we could use various open source hardware IP cores for CPU, GPU and whatever else is needed, similar to Milkymist, Open Graphics Project or Project VGA. That would be really cool. Cool, but relatively expensive and power hungry. Any idea how many you need to be making before getting the design burned into silicon becomes cost effective? From my point of view a GPU is completely useless without drivers / specifications, thus practically it is not better at all from a basic VGA 2D accelerator IP core. At least an FPGA based open source IP core design *could be* improved in time without changing the PCB. Just think the possibilities. On the other hand, a closed unsupported GPU is dead from the start. If you want a fast and efficient cpu with a good set of interfaces for making a phone or tablet they tend to have a gpu in them too, even if we can't use the acceleration at the moment. It's like things with an iPod dock - it's a useless feature for me, but something with one may still be better than something without for entirely separate reasons. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Fwd: [FOSDEM] Cross-Distribution devroom: Call for Participation
What about having SHR, QtMoko, hackable, FSO etc. share one session? Maybe sort of a round table? Something like Community driven Distributions for Smartphones Who would like to represent his/her project? Who would like to moderate?

Let me be the first (I hope): There will again be a cross-distribution miniconference at FOSDEM this year. People or distribution projects who are interested in joining it are hereby invited to communicate that desire. For practical purposes, I would like to request that one person steps forward from each involved distributions devroom, so that we can list the participating projects on our website (as during previous years), but also so that I have some contact within each project in case it's needed. People interested in holding a session should let that intention be known on the distributi...@lists.fosdem.org mailinglist, with the following information: - Their name - A (short) bio, to be put on the website along with their speaker name - (optionally) a picture of themselves - The title of their session (which will go on the website and in the booklet) - A (short) abstract describing the session in further detail. - The desired approximate duration for the session. Sessions can be talks, round tables, BoFs, or any number of other things that could generally benefit from an audience of distributions developers. In the case of BoF or round table sessions, note that I will still consider the submitter to be the 'speaker', though their role will probably be more something of a moderator. The deadline for submissions is December 22nd. -- The volume of a pizza of thickness a and radius z can be described by the following formula: pi zz a ___ FOSDEM mailing list fos...@lists.fosdem.org https://lists.fosdem.org/listinfo/fosdem ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
