This is exactly the tension behind the dicussion - while arm64 machines are mainly mobile so far, we're finally starting to see bigger and more capable systems that you'd actually be happy to use as a desktop/laptop. Hence Wookey's question - is it possible to have a single sensible answer for both the (large) mobile hardware user base and the (smaller, but growing) bigger system users? We've seen conflicting information in that thread, hence asking here! :-) Is it true that most PCIe graphics cards (and drivers) will also support GLES as well as GL? I've seen that asserted.

Hi Krishna, If you're looking at the kernel in http://images.validation.linaro.org/x86/debian/vmlinuz-3.16.0-4-amd64 then I believe that's just a normal Debian kernel and the linux-headers package should definitely exist for it. I'd try the linux-headers-amd64 package first, described as "Header files for Linux amd64 configuration (meta-package) This package depends on the architecture-specific header files for the latest Linux kernel amd64 configuration."

Google Summer of Code - interested?
Hi folks, As a follow-up to my work in LEG on assembly scanning and optimisation for AArch64, we're considering applying as a mentoring organisation for the Google Summer of Code [1] this year. There's quite a lot of code out there that may benefit from porting (whether for support of AArch64 or for better performance) and I think we could usefully get some students involved to help with this. I'm planning on doing the bureacracy for the SoC application in the next few days. So, the reason why I'm posting about that here: is anybody else interested in joining in? Are there any other projects in/around Linaro where: a) a student could do some useful work; b) we have somebody prepared to act as a mentor ? If so, please let me know. The more ideas we can suggest for summer projects like this, the more likely we are to be accepted as a mentoring organisation by Google.

I saw this reported separately elsewhere this week:

which also suggests it might be a change in perl 5.14.

Technically it *can*, but you'll then have to be responsible for dealing with all the extra register save/restores for context switches.
