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/hobbies/post-o-moich-ostatnich-dzia%C5%82aniach/ Wed, 22 Apr 2026 12:25:01 +0000 https://www.siho-shin.life/hobbies/post-o-moich-ostatnich-dzia%C5%82aniach/ Cześć! Ja mam na imię Siho! Albo możecie nazywać mnie Witekiem - Witek to moje polskie imię. W tym poście, będę pisał o rzeczach, które się dzieją w moim życiu w tym miesiącu. W kwietniu, przegotowuję się do badań niebezpieczeństwa informatycznego. Nie mamy dużego postępu, ale nad czymś pracowałem! Ale ostatnio się uczyłem na egzaminy. One dzisiaj zaczęły i skończą dwudziestego ósmego. Ciężkie czasy są przede mną. Również, w dzisiajszym czasie nie dobrze spałem. 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/todays-song/todays-song-tini/ Sun, 19 Apr 2026 14:09:08 +0000 https://www.siho-shin.life/todays-song/todays-song-tini/ https://www.siho-shin.life/todays-song/todays-song-%EC%9E%90%EC%97%B0%EC%82%AC%EB%B0%95%EB%AC%BC%EA%B4%80/ Fri, 17 Apr 2026 12:25:51 +0000 https://www.siho-shin.life/todays-song/todays-song-%EC%9E%90%EC%97%B0%EC%82%AC%EB%B0%95%EB%AC%BC%EA%B4%80/ A song that brings me back to the childhood. https://www.siho-shin.life/hobbies/learning-polish-from-song-urke/ Fri, 17 Apr 2026 10:55:35 +0000 https://www.siho-shin.life/hobbies/learning-polish-from-song-urke/ In this post, I’ll be learning Polish language from the song “Urke” by Wilki. <Verse 1> Nic nie przychodzi do głowy Samotny człowiek w środku dnia Zupełnie sam Na ulicy gwar Zgubione szczęście Nigdy nie wraca choćbyś chciał Tyle w życiu się zmienia Zaufaj przeznaczeniu In the first line, przychodzić is not a part of indeterminate/determinate thingy. Its perfective verb is przyjść. This line means “Nothing comes to my mind.” https://www.siho-shin.life/todays-song/todays-song-%EC%B2%AD%EB%A1%9D/ Thu, 16 Apr 2026 11:06:10 +0000 https://www.siho-shin.life/todays-song/todays-song-%EC%B2%AD%EB%A1%9D/ I want to play this song with my guitar some day in the future. https://www.siho-shin.life/posts/new-fedora-desktop-setup/ Tue, 14 Apr 2026 22:55:54 +0000 https://www.siho-shin.life/posts/new-fedora-desktop-setup/ Today, I have a class where I need to use Mac OS or Linux-based OS, because we have to run docker or k8s. So before class, I grabbed my old, dusty Dell laptop and turned it on. It was running quite nicely, but it was missing some aesthetics. How about I make it very minimalistic and very dark-themed? The final result First, I made my background color pitch black. Not just black, #000000. https://www.siho-shin.life/todays-song/todays-song-%EC%8B%9C%EC%9E%91/ Tue, 14 Apr 2026 17:48:09 +0000 https://www.siho-shin.life/todays-song/todays-song-%EC%8B%9C%EC%9E%91/ Like this song because this year is the beginning of my life as a researcher. I need courage. https://www.siho-shin.life/todays-song/todays-song-znowu-pada-deszcz/ Mon, 13 Apr 2026 15:22:28 +0000 https://www.siho-shin.life/todays-song/todays-song-znowu-pada-deszcz/ Nie chcę wiedzieć jak i co Po co mówić to nie to Nie umiałem kochać wprost Znowu zakpił los Really like the pre-chorus. https://www.siho-shin.life/devs/making-a-secure-code-testing-environment-0/ Mon, 13 Apr 2026 14:54:51 +0000 https://www.siho-shin.life/devs/making-a-secure-code-testing-environment-0/ What should I implement?

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.

This song cheered me up during the hard days. https://www.siho-shin.life/todays-song/todays-song-%EC%88%98%EC%84%B1%EC%9D%98-%ED%95%98%EB%A3%A8/ Sun, 12 Apr 2026 14:06:29 +0000 https://www.siho-shin.life/todays-song/todays-song-%EC%88%98%EC%84%B1%EC%9D%98-%ED%95%98%EB%A3%A8/ There’s something about this song. The swing rhythm adds a vibe to the song. I haven’t fully understood the lyrics, but still, it’s a good one. https://www.siho-shin.life/posts/hello-world/ Sun, 12 Apr 2026 10:36:35 +0000 https://www.siho-shin.life/posts/hello-world/ Hi!
