Hi Shankari, It sounds like you are off to a good start. I have something that needs to be done, that I think you can help with, and that matches where I believe you are in your status with being able to evaluate the kernel. In general, there's a lot of information on the elinux wiki which is stale, which needs to be updated or archived, or maybe even just removed. This section of the Boot Time page has a lot of material in this category: https://elinux.org/Boot_Time#kernel_speedups Can you validate the information on these 2 pages: * https://elinux.org/Disable_Console * https://elinux.org/Preset_LPJ This would consist of reading through the material, and testing the described techniques on your machine. This will involve booting the machine 2 ways, with a particular kernel command line option and without it, and then reporting back the final boot time for both. You can use the timestamp for the "init process" string as your final boot time, for the purposes of this exercise. Helping me to update the elinux wiki material on boot time would be an immense help, and is one of my main goals for the boot time SIG in 2025. Don't hesitate to ask questions if you have any. BTW - you can just report your findings to me and linux-embedded list, but alternatively (and even better) would be if you could also update the wiki pages themselves with your information based on recent kernels and hardware. To do this, you will need an elinux wiki account, which you can make online on elinux wiki.org by going to this page: https://elinux.org/Special:CreateAccount Anyone else reading this who wants to also participate in this project to update the elinux wiki boot time information, please contact me. Thanks. -- Tim
