BSP Layers and Reference Images for Yocto Project Issue Tracker

Description: Update i.MX Linux downstream kernel to NXP L5.15-2.2.x-imx / kernel.org v5.15.129

Description: PREEMPT_RT was not enabled by default on RT Downstream images

Workaround: PREEMPT_RT config depends indirectly on !KVM, so make sure that KVM is not set

Description: Some kconfig option required by some systemd functionality are missing in the kernel config, add those.

Description: Update Linux Kernel to 5.15-2.0.x-imx version, as included in NXP 5.15-2.0 BSP.

Description: Update Linux Kernel patch version to 5.4.193

Description: Update Linux kernel to 5.4.161

Description: Unfortunately, CMA needs to be in low memory and to be consecutive is not allowed to cross any other reserved sections. This severely limits its maximum available size and it looks like there is no consecutive 2GB block available that would meet all these conditions.

Workaround: Luckily, one may simply override the amount of CMA via Linux kernel command line parameter. E.g. for the BSP:
setenv setup 'setenv setupargs console=${console},${baudrate} console=tty1 consoleblank=0 earlycon cma=1376MB'
saveenv; boot
Or in the Toradex Easy Installer case:
setenv teziargs cma=1376MB; saveenv; boot

Description: CMA memory allocation is a fixed value and takes up too much space on certain SKUs. Drop the configuration of the CMA in the device tree in favour of specifying it in the kernel config with a size of 256MB or 12% of total memory which ever is less.

Description: Integrate all the changes into our buildsystem/userspace which were released in NXP L5.4.70_2.3.2 patch release.

Description: Update Linux kernel to new NXP L5.4.70-2.3.0 release.

Description: Use KBUILD_DEFCONFIG in OpenEmbedded to define the defconfig to build the kernel from. Toradex is now using the defconfigs from the kernel-repo instead of providing separate defconfigs in OpenEmbedded. However if you wish to provide your own defconfig in OpenEmbedded you can still do so.
