PDAs, Cellphones, Wireless "With the Samsung Galaxy S4 presumably coming soon, many are excited about the possibility of running a more stock Android-based experience, like CyanogenMod, on the hardware. It looks like that's going to be a slower transition than many were hoping, as the current Samsung CM maintainers have said that they have no plans to support the device." If you like custom ROMs, don't buy Samsung. As simple as that.

The reason is interesting

Some of the decisions they have made to help do this just aren't very developer-friendly, and some even violate the GPL


There are two variants which will be a pain to maintain, [and] the bugs we have on the S3 will probably be there on S4, too (camera), and we all know Samsung ability to release sources while staying in line with mainline. Yes Qualcomm releases sources, but Exynos sources we had were far from [working on] actual Galaxy products. I'm pretty sure the same will happen for this one.

I wonder if/when we'll ever have an open-source kernel driver for big.LITTLE machines. The Exynos 5 Octa is the first such machine on the market, and it will be interesting to see how this bimodal strategy plays out against the middle-road taken by Krait and Swift.

At the very least, it will be important for the future of the Linux kernel to support these kinds of heterogeneous processor architectures. And if ARM wants to get their upcoming A57/A53 designs into the datacenter, they need mainline kernel support.

Linaro (sp?) is doing a bunch of work in the mainline kernel scheduler to support aMP (asymmetric multi-processing). This would allow you to access *all* of the CPU cores (A7 and A15) and gain finer-grained control over which processes go to which cores. My guess is that it won't appear in Android until 5.0. But, at least it's being worked on.
