Default Some answers from Ricardo Cerqueira (CM)

Yesterday I had a short chat with arcee.
A huge thanks to him for taking his time to answer these rather "easy" questions.
I focused mainly on the questions which are floating around at xda these days, now we do have some educated answers (aka "the truth").
If someone wants to read a little more, I had collected a couple G+ quotes about Nvidia/LG from him some time back, see here.

To make this post clearer I removed some of the crap I wrote and focused on the important answers from him.
Didn't change anything in his lines of course.



Quote:
tonyp: first, what's your opinion about LG & Nvidia here.
tonyp: at least it looks like we'll get an official update eventually, Paul's post from his internel LG source looks promising
arcee: LG has been working on that model since February
arcee: as far as I know, they've been stamping out bugs ever since
...
arcee: in any case, there's 2 sets of issues for a device like the 2x
arcee: 1 - for people like me, nvidia is utterly useless
arcee: I can't do anything on a tegra device unless the vendor does it first
arcee: 2 - as far as stock updates are concerned, that's almost entirely up to LG
Quote:
tonyp: yes, that's really something TI and otheres are ahead of Nvidia :(
tonyp: but shouldn't LG have some kind of reference source code?
tonyp: aka something that would help "people like you" to implement it yourself
arcee: the reference code is nvidia's
arcee: LG, or any other nvidia customer, can't share it. even if they customize it (and they do), it still started from nvidia intellectual property
tonyp: yes that's obvious
tonyp: what I meant was if LG needs help from Nvidia or if they could help themselves with these reference source code
arcee: they usually have to work together, especially early on
arcee: nvidia is sloppy, their first iterations tend to be, to various degrees, broken
Quote:
tonyp: Is the tegra2 chipset a problem here?
arcee: no, it isn't
arcee: the chipset is common as much
arcee: *muck
arcee: the problem is that nvidia chose a very uncommon approach to their android design
arcee: in particular, the userspace libraries and HALs have a ton of hardware-specific logic
arcee: **** that on other platforms is confined to kernel space (like "how to enable the audio amplifier" or whatever), is put in libraries when it comes to tegra
arcee: so for the most part, you can _not_ use a device's libraries on another, unless they share the same hardware components
arcee: and since nvidia publishes zero code, we can't just write our own
tonyp: iirc even things like auto brightness are controlled with nvidia libs?
arcee: yes. sensors, in this case
Quote:
tonyp: and how specific is this implementation - would we need another device which uses the star platform (which aren't many) or could the Samsung Galaxy R for example help as well
tonyp: you wrote at Twitter that the ZTE Grant (or Mimosa) X won't really help
arcee: at all
arcee: the star, the galaxy R, and the grand X are completely different devices
arcee: different components, different resolutions, different radios
arcee: different audio amps, different panel manufacturers, different almost everything
arcee: the designs have nothing in common other than being T2
tonyp: so it's either LG or nothing?
arcee: yes
Quote:
tonyp: and you're planning to get CM10 to the 2x then? :)
tonyp: because if I understood you correct you won't release any "broken" releases like you did with CM9 anymore. I do get the point, people blaming the apps when in reality the facebook rotation crash is related to a failed attempt of 2d hardware drawing.
arcee: if LG does come out with a release I can use, yes
arcee: else, no
tonyp: that's something :)
tonyp: and which updated libraries are exactly needed? Or are there too many to list?
arcee: pretty much everything
arcee: ICS is just too different from GB

Thanks a ton bro
Clears out any confusion regarding what will be of use, and what will not be if any use to us, plus who is to blame for this mess.

Many thanks Tonyp for this, so as I can see, the problem is nVidia...And the same what happened to us with O2X can happen to Tegra3 users... So bye bye Nexus 7...and I do not understand Google why they choose Tegra3 for Nexus7... I will never buy anything which will contain something from nVidia company....

I will for sure get a N7 as soon as it is launched here in the EU. It's a Nexus device after all.
And I don't think that he said Nvidia is the only one to blame - but don't make this thread to a LG vs. Nvidia one, so let's not start with that!

Man TonyP, you've tested his nerves quite badly, answering those boring questions again and again...
