Major opensource upgrades (Dunfell → Kirkstone) are :- GCC (9.3 → 11.3) , glibc (2.31 → 2.35) , glib-2.0 (2.62.4 → 2.72.3), systemd (244.3 → 250.5) , busybox (1.31.1 → 1.35.0)
Netflix upgrade, youtube
GCC compiler
Maintainability - Dunfell 4 years ; Kirkstone 2 years ; CVE Dunfell is sill open (Refer Yocto mailing list), Upstream dunfell 3.1.24 has open CVE
Build time - reduce number of default dependency (make build faster in first/second time)
meta-rust is in core
software bill of material (security infrastructure)
share state - c standard. faster sstsate performance due to decompression standard cstd (twice faster than xz)
license management tool improvement (more accurate license compliance)
Kirkstone need minimum 4.x kernel (refer systemd)
linux_kernel_header does not mandate

Migrate RPI4 32 bit to Yocto 4.0
support@rdkcentral.com
Kirkstone (Yocto 4.0) can be built using Ubuntu 18.04, 20.04 or 22.04 VMs. All these variants need additional packages to be installed over the vanilla version.
To tackle the build issues from moving one version to another, we have decided to split the problem into different subtasks. So instead of building a complete image at one go, we have planned for the generation of the following images:
These images need to be tested in cmf, to ensure that nothing has broken the existing system.
In order to provide a smooth transition without disturbing the existing branch, we have created a branch called `feature-kirkstone` for non-OE layers and another branch called `rdk/kirkstone` for OE layers and bitbake.
The machine configuration shall have a distro defined “Kirkstone”
Note: A detailed migration steps will be update before March 02,2023
