Revision as of 06:24, 24 May 2013

John's braindump:

The FSF wants to do something to make a completely free tablet a reality.

An important step here is the video hardware. Some chipsets have free drivers, but rely on proprietary firmware. The FSF is considering a project to replace this proprietary firmware with free firmware.

1) We should choose a chipset that is very new, so that the product will still be useful for some time.

2) We should choose something that is used in many different products, if possible.

3) We should choose something that is present in products that have the best chance of being fully free otherwise. If it has a USB port, it can get free wifi that way, for example.

4) We should pursue better relations with manufacturers to get documentation at least, or in the best case to convince them based on our reverse engineering success to do the right thing from the beginning.

We are chatting about the project in #fsf-tablet on irc.oftc.net.
