Known Gaps
When extending kernel support to a platform, its components and features must be validated, and issues may arise during testing. This page is divided into two sections: Platform Components and Features Not Yet Validated and Known Issues.
Platform Components and Features Not Yet Validated
To help users understand the current validation status of the Xavier platform, the following tables list the platform components and features that have not yet been validated and are still awaiting testing.
| Area | Description |
|---|---|
| Stability foundations | Thermal zones, DevFreq, EMC scaling, and watchdog support. |
| Storage and I/O | Such as SD, NVMe, USB 3.0, Wi-Fi, and Bluetooth. |
| Power Management | Verification of suspend/resume functionality, idle states, and thermal behavior under sustained workloads. |
| Area | Description |
|---|---|
| Audio | Validation of audio playback and capture functionality through the supported audio interfaces and codecs. |
| Area | Description |
|---|---|
| DLA (Deep Learning Accelerator) | Validation of DLA functionality for AI inference workloads and framework integration. |
| PVA (Programmable Vision Accelerator) | Validation of PVA support for computer vision and image-processing workloads. |
| RCE (Real-Time Camera Engine) | Validation of the camera processing firmware and real-time camera pipeline functionality. |
| RTCPU (Real-Time CPU) | Validation of the real-time coprocessor firmware and communication mechanisms used by subsystems such as camera, sensors, and other time-critical platform services. |
| Area | Description |
|---|---|
| Secure Boot Chain | Validation of the secure boot process, ensuring that each stage of the boot chain verifies the authenticity and integrity of the next stage before execution. |
| Disk Encryption | Validation of storage encryption mechanisms to protect data at rest and ensure secure access to encrypted partitions. |
| OTA (Over-the-Air Updates) | Validation of remote software update mechanisms, including update deployment, installation, and rollback procedures. |
| OP-TEE | Validation of the Trusted Execution Environment (TEE) provided by OP-TEE, including secure services and communication between the normal and secure worlds. |
| Bootloader Capsule Update | Validation of firmware and bootloader update mechanisms using capsule-based updates to ensure secure and reliable firmware deployment. |
Known Issues
When bringing up support for a new kernel version on a platform, unexpected issues may arise. This section describes known issues with the platform components and features tested.
