Hello,
The warning message “All bds consumed, restart now” from the SDMA driver on your Toradex device is typically a normal part of the driver’s operation under high system load conditions. It indicates that all buffer descriptors have been used, prompting the driver to restart the channel to maintain processing.
While this warning is generally not harmful, if it occurs frequently and affects system performance, you might consider the following steps:
-
Check for Updates: Ensure your system is running the latest version of the Toradex BSP and kernel, as updates may include improvements for the SDMA driver.
-
Optimize System Load: Review your system’s workload to identify processes that could be optimized or offloaded, potentially reducing the load on the SDMA.
-
Driver Configuration: Examine the SDMA driver settings in your device tree or kernel configuration to ensure they are tailored to your specific use case.
Unfortunately, there is no straightforward method to disable this warning without modifying the driver code, which is not recommended. Instead, focusing on system optimization and configuration may help mitigate the frequency of this message.
I hope this helps! If you have further questions, feel free to ask.
Best regards,
Toradex AI Assistant.
