Re: [maemo-developers] Java on the 770

2006-11-15 Thread Jesper Zuschlag
Actually, from what I have been told by several ARM representatives  
its the other way around. Something in the Jazelle architecture is  
covered by one or more Sun patents, which means that ARM cannot  
disclose the architectural details to 3rd parties that isn't Sun- 
licensees.
I believe that in view of the recent open-sourcing of Java, Sun and  
ARM should sit together and solve this issue so that we can use the  
full potential of our devices. I find this whole situation ridiculously.

Seems more likely to me that Sun can't give away code that they  
have only licensed from ARM.
As stupid as it may be, Jazelle specifications are proprietary to  
ARM and ARM is probably the one that would object to Sun releasing  
jazelle-related code.
You'd think a hardware manufacturer would want people to be able to  
actually use the hardware they purchase.


If we want Jazelle to work on the 770 it's up to nokia to negotiate  
with ARM. Thus far we have seen very little interest from Nokia in  
bringing a JVM to the 770.

[maemo-developers] Q: virtual keyboard and *stealing* text selection

2006-11-15 Thread 3rdshift
Hi,

I am trying to determine how to get around a nagging bug associated 
with virtual keyboard in IT2006:

I have TextBuffer/TextView widget with some text in it, and an action button to 
operate on a selected block of text. 

When I select a text block, the virtual keyboard pops up and selection is still 
visible. But the second I press my action button and before button's 
signal_click event is delivered, the selection block is cleared (deselected) 
and text buffer claims no selection is made on the text! 

Has anyone seen or dealt with this problem before? If so, is there any way to 
get around it? 

any hints would be highly appreciated,
-Vlad

It will be officially supported starting sometime next year. I'd say
your best option is just to try it, and if it's not too slow for your
needs, go ahead! Hopefully (surely) it will only get better
performance-wise in the future.

Re: [maemo-developers] Unresolved issues (Week 45)

2006-11-15 Thread Larry Battraw

 I would guess that this is for the forthcoming 870 (?) device that
actually includes a plug for a headset.  Having the ability to sense
headset presence would be natural, and the codec register name sounds
reasonable for a wired headset too.

This might be related.  The new kernel includes something that can
detect a headset connected to Retu/Vilma (which appears to be a nokia
custom ASIC).  I just took a really quick look at the code and it frobs
some registers called RETU_REG_AUDTXR but they use magic constants (bad
coder, no beer for you) for the value so I don't know exactly what it's
doing.  The register they're poking is commented as the "Audio Codec Tx
register" though.

It might be bluetooth or it might be something else.  You might have to
poke a /dev file first.  I'll take another look at the code when I have
time.  Or someone with a bluetooth headset could just try it...

I'm probably just thick, but are you asking 
  * (when) are we going to ship a product (device and/or firmware)
with bluetooth audio working out of the box?
  * (when) are we going to ship a product (device and/or firmware)
with the necessary drivers for someone else to implement
bluetooth headset support?
  * (when) are we going to document how someone else could implement
some driver?
  * something else?

It would be much more clear and easy to pass around a mail stating
something like "I want to do $this, and the easiest way to do that would
be $x. But I can not do that because the 770 does not support $y and
Nokia being the only one with the sources/documentation/whatnot is the
only one in position to implement it. Another option would be to $z
(rewriting the kernel) but that would be just too much for me. So is
Nokia going to do something about $y?"

Or something like that. I hope you get the idea.

Well, short explanation would be "Because Maemo OS2006 uses EABI"

Here is the quote from http://www.maemo.org/downloads/releases.html:
Maemo 2.0 introduces a major binary break due to the adoption of EABI toolchain 
and 
several API changes requiring porting of all existing maemo 1.1 applications to 
maemo 2.0

And.more detailed explanation:

I've been writing this little application called maemo-blog; however it
currently only supports Blogger and MetaWeblog APIs: no LiveJournal yet
(and AFAIK LiveJournal doesn't support any other APIs than their own).

If you want something to port, there's Drivel[1] that could be quite
easy to port, it's C and Gtk+. Or if you don't want to get your hands
dirty with C, you could try BloGTK[2].

Well, I have to admit I didn't try it with OS2006. Can you give a short
