Topics

• 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.
