Linux/DRA77P: Fastboot not achieved

Hi Padmesh,

do you refer to systemd services started at later stages of the boot process?
You should be able to use "systemctl disable <service>" command to disable unused services, you can refer this document for detailed explanation:
docs.fedoraproject.org/.../index.html

Hi Yordan,

Sorry for the misunderstanding, I do not want to disable the services, i wanted to disable the scripts shown by them.

This is the log I get.

What do i do to silence them ? By this have I achieved the kernel fastboot ?

Regards,
Padmesh

Hi Padmesh,

I think you should be able to disable services output by adding "StandardOutput=null" to the corresponding *.service files located in /lib/systemd/system directory of the rootfs.
Note that the Application Report you referred focuses on optimizing only to the u-boot and kernel execution times, not the userspace services. In the document you can find a way to measure boot times with and without optimization patches applieda and compare them.

Regards,
Yordan

Hi Yordan,

Thanks for the guidance, I was able to disable prints by the services.

The thing I am facing is that, am not able to run ./list-boot-times.sh.  The following is displayed,

ls: m-*: No such file or directory

ls: k-*: No such file or directory

ls: u-*: No such file or directory

cat: can't open '/tmp/m-kernelstart-time': No such file or directory
cat: can't open '/tmp/k-start-time': No such file or directory
Kernel Decompression time,0
cat: can't open '/tmp/k-user-space-entry-time': No such file or directory
Kernel Exec time,0

What am I missing here ? I have followed the patches. I am not able measure the performance parameters.

On applying the patches, I found that the eth0 is not able not showing IP address. Is there anything preventing it.

Hi,

The readproc utility described in section 5.1 reads the measurements from the chosen node of the device tree and dumps them into /tmp. Please check the files under "/proc/device-tree/chosen".

if the ethernet module is converted into a module, eth0 may not show an IP address. Please check the kernel configuration.

regards,

Venkat

Hi Venkat,

Under /proc/device-tree/chosen, I am able to see the timing parameters.

I changed the directory to /proc/device-tree/chosen and was able to see the following:

Are there any ways to optimize after the kernel execution ?

Regards,

Padmesh

Hi,

Can you confirm that you are using single stage boot mode and the device tree has the required entries as shown in

review.omapzoom.org/

For optimizing after kernel boot, there are a number of documents online. One for example below.

bootlin.com/.../boot-time-slides.pdf

regards,

Venkat

Thanks Venkat,

I was able to solve the issue, currently I'm looking into further optimizations in user space.

Regards,

Padmesh

Hi Venkat,

I used the fdtput command with bootargs on the required dtb and placed it in qspi flash as well in the emmc.

Also I cleaned up the filesystem and added it again.
