Here are my starter question.
(Some of these I now know but I had these question a year ago when we
started looking.)
1) Is LAVA suitable for personal machine deployments?
I think the initial focus of this project should be a board lab
environment. This seems to be the natural environment of LAVA.
That said, I think the Yocto Project recommended test tool should scale
down to situations where a developer has a board attached to her PC
where she does bitbake builds and then runs test locally.
What issues do you see for LAVA in this situation?
2) We want to test images as produced by bitbake, can we do that with LAVA?
For Ubuntu and other distros, LAVA uses a tool at test start to combine
a generic image and a hw specific add on. Bitbake already does this.
Can we bypass this step and test the images just as they were produced
from bitbake? Do you already have examples of this working?
3) What types of image deployment / boot can you support?
The traditional LAVA image deployment is to use multiple partitions on a
boot storage device: a master image and a test image. I believe LAVA
controls the boot process over a serial port to direct the boot flow to
the master or test partition.
What other scenarios do you support and do you have examples of these
working already?
* Network boot of kernel & standalone initramfs?
* Network boot of kernel w/ NFS root?
* SDMUX based boot from one of two SD cards based on dispatcher control?
* BBB bootmode can be controlled via a Ethernet controlled relay board,
can LAVA supoprt that?
* others?
4) Yocto Project supports ARM, x86, MIPS, and PowerPC architectures. Is
that an issue for LAVA?
We are starting with BeagleBoneBlack (ARMv7) and Minnow board (x86) but
will eventually want to cover all the architectures. YP test
infrastructure users will want to add their own boards.
How hard is this?
Is LAVA flexibility enough to control various boards?
5) What is the size of the team that works on LAVA? How many people are
using outside of the linaro.org LAB?
