boot time optimisation references b2qt i.MX 8X
-
What reference implementations are available for boot time optimisation?
Ideally for NXP i.MX 8X (but any i.MX 8 or i.MX 6 or similar would be a start).On one extreme, 24 seconds for b2qt reference implementation, i.MX 8X:
https://dev.variscite.com/var-som-mx8x/mx8x-b2qt-kirkstone-5.15-2.0.x-v1.0/yocto-recovery-sd-card/On the other, 1.2 seconds, i.MX 6:
https://www.qt.io/blog/tag/boot-timeThe Qt boot-time blog has many good ideas.
But would be great to have more details of how to strip down the kernel etc.
Where can we find more details, and ideally a reference implementation please?
e.g. a reference linux kernel defconfig?Thank you
