initramfs-module-luks-ftpm: Add fTPM support

2026-03-26T14:40:56+00:00

Add initramfs module to dynamic-layers/tpm-layer providing LUKS2 full disk encryption with TPM-sealed keys for TI K3 platforms. Keys are sealed by firmware TPM (fTPM) running in OP-TEE and stored in eMMC RPMB. Features: - First-boot in-place encryption with tpm2_getrandom key generation - TPM-sealed key storage via persistent handle 0x81080001 - Automatic unlock on subsequent boots - Space verification ensuring 32MB available for LUKS header The module is built only when meta-tpm layer is present and gets included in initramfs only when DISTRO_FEATURES='luks' and MACHINE_FEATURES='optee-ftpm' LUKS packages (cryptsetup, tpm2-tools, tpm2-tss, optee-ftpm, e2fsprogs-*) significantly increase initramfs size beyond the default 131072 limit. Increase INITRAMFS_MAXSIZE to 200000 to accommodate these packages. Signed-off-by: Shiva Tripathi Signed-off-by: Ryan Eatmon

packagegroup-ti-core-initramfs: move cifs-utils to dynamic-layers

2025-11-05T23:55:43+00:00

Since cifs-utils is available in meta-openembedded, not OE-Core, it cannot be added to this packagegroup unconditionally, as meta-ti-bsp doesn't depend on meta-oe, only recommends it. As it breaks yocto-check-layer now, move cifs-utils addition to dynamic-layers to be added conditionally on meta-oe presence. Signed-off-by: Denys Dmytriyenko Signed-off-by: Ryan Eatmon

u-boot-ti: Move UBOOT_VERSION into dynamic layer

2025-07-10T20:36:25+00:00

The gitpkgv class we are using to set UBOOT_VERSION is located in meta-openembedded. We do not want to depend on meta-openembedded to keep meta-ti-bsp as light as possible, and the naming of UBOOT_VERSION is not a requirement, just a nice to have. Dynamic layers allow us to use the class if it is available in the build, but not require it. Signed-off-by: Ryan Eatmon

mesa-pvr: remove dynamic-layer append for llvmpipe

2024-11-06T19:48:12+00:00

The mesa.inc that we inherit from oe-core now has the required parameters. This conditional append is no longer required. This reverts commit dbc6afc46e55b247606dfad5238137c8fa807843. Signed-off-by: Randolph Sapp Signed-off-by: Ryan Eatmon

mesa-pvr: add dynamic-layer append for llvmpipe

2023-09-20T22:30:56+00:00

Meta-clang provides a bbappend for mesa to use clang to accelerate it's rasterization with runtime code generation through the use of llvmpipe. With the addition of mesa-pvr we no longer get this for free with the blanket mesa bbappend on the devices that explicitly request mesa-pvr so lets add a dynamic layer to append the same args meta-clang does. Though the number of devices that would select pvr-mesa and still want to use software rendering is small, it's not zero due to debug and testing purposes.
