Re: [yocto] Problems with Torvalds Kernels (6.10-rcX)
Hello Paul,
Many Thanks (not entirely politically correct English language), I
guess it was one of the errors:
PREFERRED_VERSION_linux-torvalds ?= "6.10.%"
I swapped "torvalds" with "mainline", as U did.
But the one I've bumped to is the one I just noticed at the end of
writing the original email:
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/conf/machine/beaglebone.conf
5 SOC_FAMILY = "ti335x"
6 TARGET_ARCH = "arm"
7
8 DEFAULTTUNE ?= "cortexa8hf-neon-"
9
10 require conf/machine/include/soc-famil
y.inc
11 require conf/machine/include/arm/armv7a/tune-cortexa8.inc
12
===>>> 13 PREFERRED_PROVIDER_virtual/kernel = "linux-stable" <<<===
14 #PREFERRED_PROVIDER_virtual/kernel = "ti-linux"
15 KERNEL_IMAGETYPE = "zImage"
16
17 PREFERRED_PROVIDER_virtual/bootloader = "u-boot"

Anyway, Ur @ somehow prompted me to start moving after 3 days og
banging my head off the Chinese wall...
I did fix the mainline kernel recipe, in some clumsy way, but for now
I have @ least a working version (or I think I have, since now I am
compiling kernel 6.10-rc2, I need to wait till the end of the process)
!
U did organize the whole mainline thing in a very structured way, my
mainline 6.10-rc2 .bb recipe is a complete mess
At least it does work (with sticks and ropes)! :-)))
Very soon I will release this recipe in my meta-bbb/ layer, inherited
from Scott Ellis. Scott kept in there machine/
.../meta-bbb/conf/machine/ directory, U did not.
Implementation detail! ;-)
Later... YOCTO Folks!

Hello Yocto Community,
I am trying to understand how to handle (beside linux-stable) another
pre-released stream of kernels, handled ONLY by Linus.
I called it linux-torvalds. Whatever I tried last week does NOT work for me.
Let me start describing the problem.
This is the kernel recipe I am using in my meta-bbb layer, experimentally.
Here is the pointer for kernel recipe 6.10-rc1 (on the net still
visible from github):
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/recipes-kernel/linux/
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/recipes-kernel/linux/linux-torvalds_6.10.bb
Not sure from where the variable ${SRCPV} comes from (from .../poky/meta/...)?
The .../build/conf/local.conf is NOT visible from the net, but in
nutshell, here is what I have in it (important):
## Define kernel version
## SRCPV = "${@bb.fetch2.get_srcrev(d)} <<<=== Commented out -
just to remind me about this mysterious variable
## PREFERRED_PROVIDER_virtual/kernel ?= "meta-bbb"
## PREFERRED_VERSION_meta-bbb ?= "6.1.%"
PREFERRED_PROVIDER_virtual/kernel = "linux-torvalds"
PREFERRED_VERSION_meta-bbb ?= "6.10.%"
The pattern here is PREFERRED_VERSION_.
So if your recipe is named linux-torvalds, you want:
PREFERRED_VERSION_linux-torvalds ?= "6.10.%"
As an alternative to maintaining such a recipe yourself, I recommend you
look at the following:
- The linux-yocto-dev recipe in openembedded-core/poky. This is the
mainline kernel plus some Yocto-specific patches and is regularly
updated by Bruce (linux-yocto maintainer).
- The linux-mainline recipe in my meta-linux-mainline layer. This is the
mainline kernel with no additional patches and is regularly updated by
me. See https://github.com/betafive/meta-linux-mainline for more info on
this layer.
Thanks,

[yocto] Problems with Torvalds Kernels (6.10-rcX)
Hello Yocto Community,
I am trying to understand how to handle (beside linux-stable) another
pre-released stream of kernels, handled ONLY by Linus.
I called it linux-torvalds. Whatever I tried last week does NOT work for me.
Let me start describing the problem.
This is the kernel recipe I am using in my meta-bbb layer, experimentally.
Here is the pointer for kernel recipe 6.10-rc1 (on the net still
visible from github):
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/recipes-kernel/linux/
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/recipes-kernel/linux/linux-torvalds_6.10.bb
Not sure from where the variable ${SRCPV} comes from (from .../poky/meta/...)?
The .../build/conf/local.conf is NOT visible from the net, but in
nutshell, here is what I have in it (important):
## Define kernel version
## SRCPV = "${@bb.fetch2.get_srcrev(d)} <<<=== Commented out -
just to remind me about this mysterious variable
## PREFERRED_PROVIDER_virtual/kernel ?= "meta-bbb"
## PREFERRED_VERSION_meta-bbb ?= "6.1.%"
PREFERRED_PROVIDER_virtual/kernel = "linux-torvalds"
PREFERRED_VERSION_meta-bbb ?= "6.10.%"
It then tries to pick up a latest linux-stable kernel 6.9.3 (talking
from the scratch/fresh bitbake), but since I have:
PREFERRED_PROVIDER_virtual/kernel = "linux-torvalds"
It fails, since it does not know the location where it needs to fetch it?!
If I make the following changes:
## PREFERRED_PROVIDER_virtual/kernel = "linux-torvalds"
PREFERRED_PROVIDER_virtual/kernel ?= "meta-bbb"
PREFERRED_VERSION_meta-bbb ?= "6.10.%"
It does fetch it correctly, but ONLY again kernel-stable 6.9.3 ???
Despite the line PREFERRED_VERSION_meta-bbb ?= "6.10.%"???
Where am I making a mistake here?
How to pick up linux-torvalds_6.10_rc1 recipe??? At least, then I can
continue forward?
___
I just spotted it!
It seems here is the problem!?
https://github.com/ZoranStojsavljevic/meta-bbb/blob/scarthgap/conf/machine/beaglebone.conf
5 SOC_FAMILY = "ti335x"
6 TARGET_ARCH = "arm"
7
8 DEFAULTTUNE ?= "cortexa8hf-neon"
9
10 require conf/machine/include/soc-family.inc
11 require conf/machine/include/arm/armv7a/tune-cortexa8.inc
12
===>>> 13 PREFERRED_PROVIDER_virtual/kernel = "linux-stable" <<<===
14 #PREFERRED_PROVIDER_virtual/kernel = "ti-linux"
15 KERNEL_IMAGETYPE = "zImage"
16
17 PREFERRED_PROVIDER_virtual/bootloader = "u-boot"
Thank you,
Zee
