- Kernel Lock Debugging - PREEMPT_RT patches
- See thread at https://github.com/OE4T/meta-tegra/issues/1165
- Suggestion to use kernel and kernel build instructions directly from Jetpack, to eliminate the possibility of meta-tegra patches causing issues.
- Jetpack 5.1.1 testing status
- Have a minimal testing on the master branch.
- Changes are minimal from the previous release.
- Would appreciate any other help testing.
- Tested with holoscan and IGX Orin devkit.
- Timeline for backporting new BSP into Kirkstone
- Matt was planning to work on this over the weekend.
- Will include anything currently on the PR branch, plus new MR from Kurt, plus any others after the weekend.
- Not planning to do a backport to langdale, not sure anyone is using.
- Will pull a Mickledore branch this weekend and prune some of the older branches.
- Kernel module signing will remain off by default, will add a config fragment to enable when needed.
- Didn’t seem appropriate to have kernel modules signed but not checking signing. When turning on you need to ensure you are coordinating between kernel and modules build, especially for OTA updates.
- Capsule update status
- Working on agx-xavier devkit, not yet working on xavier-nx. Next step is to prove NVIDIA instructions work on xavier-nx.
- Latest status in https://matrix.to/#/#OE4T_jetpack-5-device-update:gitter.im
- Discussed strategies related to updating bootloader components and rootfs separately.
- Release of Holoscan SDK
- Providing a layer to support discrete GPU.
- Originally targeted healthcare, now more generic.
- Mellanox, rivermax
- Recently made 0.5 release, 35.2.1 Kirstone supported. Will make a point release with the next release or two on IGX Orin Devkit.
- Secureboot with latest Jetpack
- Not fully supported yet with the latest Jetpack.
- NVIDIA is planning to release with a separate release or possibly with a future BSP.
- Overlay package on top of existing Jetpack. Ilies has early access, exploring related to chain of trust, trying to implement this first.
- Working on Secure Boot for Holoscan as well. IGX Orin devkit working with signing using the existing overlay pre-release.
- Aiming to include secureboot holoscan support with the upcoming point release.
- Add support to flash via external device with wic image.
- Discussed QT6 support
- Working with no modifications on meta-tegra
- Started using the GBM backend for QT5/6 instead of EGL streams, this is also working.
