Release Notes
NVIDIA DOCA Release Notes
NVIDIA DOCA SDK release notes containing information on new features, bug fixes, and known issues.
- Added support for signing and authenticating user DPA applications for BlueField-3, allowing only signed applications to load on DPA
- Added Redfish support for configuring all UEFI secure boot settings (disable, enable, enroll user keys, etc.) at scale, remotely, and securely
- Added alpha support for BlueMan
- Added support for the DOCA PCC library to support tracing on the device side of the application code using the call
doca_pcc_dev_trace_5(...)
. The common use case for this call is to trace a specific flow using its flow tag, which can be acquired by thedoca_pcc_dev_get_flowtag()
call. This trace call is designed to be faster than the normaldoca_pcc_dev_printf()
call, and is added as a debugging tool that does not highly affect performance. - Individual priorities in mlxconfig
- Optimized DPA RTOS performance
