Understand the architecture DOCA Core primitives Device enumerations with doca_devinfo Run sample applications Regex offload sample Compression sample: doca_compress First, our program opens a device capable of supporting hardware compression engine. The device here means PF, VF, or SF in the BlueField device, and it is stored into struct doca_dev object. Next, the compression context doca_compress is created, and the progress engine (PE) is also created. https://www.siho-shin.life/researches/learning-nvidia-doca-1/ Sun, 19 Apr 2026 23:09:36 +0000 https://www.siho-shin.life/researches/learning-nvidia-doca-1/ Today, I used doca_dev.h API to enumerate PCI functions of the BlueField device. Understand the architecture DOCA Core primitives Device enumerations with doca_devinfo Run sample applications Regex offload sample Compression sample: doca_compress To acquire the information of each interface of the device, first I had to call the function doca_devinfo_create_list. It creates an array of struct doca_devinfo. Then, while iterating through the array, I called doca_dev_open function to retrieve struct doca_dev of the device. https://www.siho-shin.life/researches/learning-nvidia-doca-0/ Mon, 13 Apr 2026 12:00:05 +0000 https://www.siho-shin.life/researches/learning-nvidia-doca-0/ Since I am assigned to research SmartNICs, I also have to learn NVIDIA DOCA. Here is the roadmap that Claude made for me: Understand the architecture DOCA Core primitives Device enumerations with doca_devinfo Run sample applications Regex offload sample Compression sample: doca_compress In this short series, I’ll go through this roadmap and document my journey on this blog. Stay tuned!
