WiFi, 3D GPU.

well, the firmware within the UMTS module is closed. Some people
(like FSF, R. Stallman) don't see this as a problem since it "can be considered
hardware". It is connected through a standard USB interface, so no difference
to the firmware within an  USB memory key.

Others have a problem with any firmware because it might have built in backdoors.

So it is not exactly clear what "free software" means in this case.

The WiFi chip needs a firmware that is injected during boot. And is stored on
the root file system of the device. This makes a Linux Distribution which includes
the firmware "non-free" (in the definition by FSF). Debian provides this binary
in a non-free repository which must be referenced explicitly by the user.

The same with the firmware (micro-operating system) that runs directly on the GPU.

There are no proprietary drivers. All are included in the Linux kernel. Only
the operating systems for the WiFi Chip and the GPU are closed binaries.

For UMTS we don't even have a binary, so we can't think about open source...

Yes or no - depending on what the meaning for free software is in this

There is none with open firmware, but all use standard serial or USB
interfaces and most communicate through standards like GSM 07.07
AT commands.

In the FSF sense this is free enough. I had a long discussion with
Richard Stallman but only about the WiFi stuff.

BTW: the GTA04/Letux2804 can be operated as a full smartphone.
Without WiFi. Just by not installing the problematic firmware and keeping
it switched off.

And none of the User interfaces currently *requires* to use the GPU
(neither Replicant, nor QtMoko nor SHR) because the CPU is fast
enough to do "normal" animations quick enough. Only 3D games
would need it.

Well, in my view, there are no "new" directions yet. It needs to be discussed
and based on what the community wants to know, achieve and is interested

The original objective of the gta04 project was to get new features into the
existing GTA02 (Openmoko Freerunner): faster CPU, UMTS and some other
improvements, and capable to run latest Linux. So it started as a motherboard

No problem. IMHO most people are subscribed on both lists.

BR and thanks for this valuable contribution,
