PDAs, Cellphones, Wireless After a few months of relative silence and vagueness, we're finally getting something tangible from Jolla, the promising mobile phone company which came forth from former Nokia employees. It's ambitious - they're not just going to create a mobile operating system, not just a mobile phone, but an entire ecosystem, including cloud services and data centres. At its heart? The beautiful city of Hong Kong. The prime target market? China.

What I read, the OS will only be partly open...bummer. bndustry. "Licensed to industry" indicates closed source, open to community participation indicates some sort if openness. We'll see !

Perhaps we can expect an Android-like development model, where the core project is open-source (though not necessarily under open governance) but all drivers and other hardware abstraction layers are closed-source.

That would seem like a necessity on ARM anyway, since the architecture is largely nonstandard and few SoC manufacturers if any publicly disclose their chipset's specs. At best you get something like Ti's OMAPs where TRMs are publicly distributed, but some parts of them (typically GPU specs) are lacunar or missing as they are licensed from someone else. At worst it's something like Qualcomm where hardware projects like Raspberry Pi have to put community pressure on the chip manufacturer if they want even such a lacking TRM.

Mer is openly governed and that's not going away.

Quallcomm is quite aggressive patent wise. The hell will freeze before their legal department passes releasing specs that reveal implementation techniques, that would expose them.
Nevertheless I hope that nouveau like project will spring out sooner or later. That will of course require one SoC generation to live longer than a couple of months.

There are projects like the Limadriver which currently supports Mali-200 and Mali-400 GPUs. There's also the Freedreno driver for Qualcomm/Adreno (Snapdragon, iirc) SoCs.

Problem is; all these seem to be reverse engineered, which means they'll almost always be behind their proprietary counterparts in performance.

Yep, they don't look decent. Like in attacking Opus codec for example.
