See https://github.com/OE4T/meta-tegra/pull/1927
Issues with changes in kernel config from linux kernel 6.12 which caused problems with capsule update. Also an issue on the master branch, resolved with https://github.com/OE4T/meta-tegra/issues/1954
Ridgerun submitted configs for tegra to kernel meta, could try to pick that up.
Windriver was putting together a kernel config
Spent some time last weekend sorting out additional patches for out of tree drivers.
Able to get both sato and weston image to come up correctly.
Pretty close - not too concerned bout exhaustive testing, not a huge update. Will get that merged this weekend.
Removed efifb=off kernel commandline parameter, implies they have done something to address the handoff problem
Have implemented flash support for hsm but not tested.

Working on patch for core, certain attributes appended to default tune for ARM
- Decided to switch from march to mcpu, more optimal set of micro attributes
- Ran into issue where clang assumes some cortex have crypto, gcc does not
meta-tegra change at https://github.com/OE4T/meta-tegra/blob/master/conf/machine/include/tegra234.inc#L6
patch at https://patchwork.yoctoproject.org/project/oe-core/patch/[email protected]/
Have tended to focus less on CPU specific optimizations support on tune features.
Don’t want to introduce cpu optimizations which would break compatibility with Nvidia default Ubuntu features.
