im currently a arm user and have a armv7l build im expanding this to arm8
and am bootstraping a build currently patching as i go the linaro
repositories are a
great resource [thanks for the fish], once i proceed further ill feedback.
i abandoned the "foundation" and have now loaded qemu from git and using
the linux-user bits for a "hybrid" chroot build.
besides it been a bit slow all builds are done in the method i explain
wanted to have it all in one.
once you have a base cross toolchain [binutils/gcc/glibc] place them all in
sysroot allong with libs/bins from host [in my case x86_64] for common tasks
getttext/make/bash/..... configure binfmt_misc mount the sysroot onto
/usr/gnemul. this allows execution of programs while "building" and allows
chrooting into the sysroot and running the build cross [x86_64] for the
host [aarch64] native will be [aarch64].
problem children like perl and python build out the box now [chroot].
There some qemu errors trying to chroot build with "waf" [samba/python]
when chrooting but it does build "cross".
expect some updates and leaching off the repositories.
any one interested in further info or has comments please shout.
I plan to develop a boot loader for an ARMv8 SOC.
So, I have a few questions about booting an ARMv8 kernel image.
1. the linux kernel image's execution state when jumping to the
entrypoint of zImage.
Take Cortex-A57 as an example:
It has 2 execution state : Aarch32 / Aarch64
(1) boot loader is running at Non-Secure EL2 Aarch64 state
Does the linux kernel zImage also need run at Non-Secure EL2 Aarch64
Is the kernel zImage possible to run at Non-Secure EL2 Aarch32 state?
Colin King sent me some patches to fixup memory leaks and some nits in
the error code path.

I want to remind everyone that if you wish to communicate anything to do with the Lab in Cambridge, then you should always use the “lava-lab(a)linaro.xn--org-9o0a alias. The people on that list include the three of us in the LAVA team in Cambridge, as well as Alan and Tyler, so we cover a pretty wide time zone.
Additionally, just because you get a reply off one of us, please don’t cut the mailing list out of the loop. If one of us is unavailable, someone else can pick up the thread.
Hangout audio and video is regularly broken for people which causes
general aggravation for people in meetings. Could we have a
'test/corridor/watercooler/coffeemachine' hangout somewhere for people
to test if it's working for them today?
Maybe there is one already?

Is there a way to set how much memory an armv8 box will get when
running in the model?
I'll really like to avoid setting up swap :-)
