I am building a custom image for 

ASUS ROG STRIX Z390-I, with Tesla T4

I will build on meta-intel. But the problem is that I am also using Tesla T4 GPU, which requires CUDA toolkit to install. And CUDA requires a supported linux distribution. So, how to setup and use the T4 drivers?

Hello,

I have a ROG STRIX Z390-I motherboard with an Intel® Z390 chipset. And I want to create a custom BSP Layer for it. Where should I start? I did not find any yocto community for ASUS. So, Any guides would be helpful.
Thank you

you don't want the leading space.

I got the idea from reading
https://docs.yoctoproject.org/ref-manual/migration-3.0.html?highlight=init_manager#init-system-selection

But this is exactly why we need some explicit examples. :-)

Thanks Robert and Raj!!

I am using Yocto 3.1 Dunfell release.

You are right about the .bbappend file. Changed the name in the overlay to new-ver.bbappend and no longer see the warning.

Tried setting INIT_MANAGER = " sysvinit" in build/conf/local.conf but looks like generated rootfs has init file pointing to init -> ../lib/systemd/systemd

Hello Yocto team:

I just started with yocto and would like to know the process for
switching the init manager from systemd to sysvinit.

I tried this options in config file
VIRTUAL-RUNTIME_init_manager = "busybox"
PREFERRED_PROVIDER_udev = "sysvinit"
PREFERRED_PROVIDER_udev-utils = "sysvinit"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
DEFAULT_DISTRO_FEATURES += " sysvinit"

I see a warning when building my machine:

No recipe for target:
/recipes-core/sysvinit/sysvinit_2.88dsf.bbappend

Please find out which layer is adding this bbappend you could use

bitbake-layers show-appends sysvinit

It seems recipe version is newer perhaps and the bbappend is still made
for older recipe, these things happen when you mix release branches for
different layers.

When I run this build on my target it still shows me systemd init manager...

Not sure if I am missing any options.
Could you please let me know if there are any pointers I can refer to?

Thanks,
Priya

Why do I (always) point out the obvious?

And I do need... Geniuses are not meant to fix The World to understand them!?

Geniuses should understand The World (and act properly)!

Extras to geniality, do you, YOCTO primes, think?

Robert... If I am correct, i'm I?

Should you include in docs some examples??? Yes, U should!
As for an example fix:
poky/meta/conf/distro/include/init-manager-*.con, NOT
conf/distro/include/init-manager-*.conf

(full path is more explicit, isn't it?)

And some local.conf examples/snippets (since all descriptions are here
and there very dry):

## Add systemd service
INIT_MANAGER = "systemd"
## DISTRO_FEATURES_append = " systemd"
## DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
## VIRTUAL-RUNTIME_init_manager = "systemd"
## VIRTUAL-RUNTIME_dev_manager = "systemd"
## VIRTUAL-RUNTIME_initscripts = ""

Where INIT_MANAGER = "systemd" replaces all commented commands below....

My two cent advice,

Hello all,

to speed up builds, we would like to make the CI generated sstate-cache available via internet. Due to IP concerns, we don't want to make it publically available but for authenticated hosts only.

[1] indicates it is possible to serve the sstate-cache over http with basic authentication [2].

How does one set the username & password? By putting it into the URL like in the following example, or are other ways available?
```
SSTATE_MIRRORS ?= "\

There is an example in the commit you sent, so I would say:
SSTATE_MIRRORS ?= " \

?

2.17.1

With zephyr v2.5.0, EFI binary support has been added for x86 board (64-bit mode).

To achieve this, an python tool[1] has been added to convert zephyr ELF file
into an EFI appliable. But currently this does not work with Yocto
cross-compilation env.
This patch fix this issue and allow to build zephyr.efi

Could you please rebase these patches for v2.5.0 latest master ?
