I recently participated as a speaker at DebConf 24, where I contributed as a Linux perf contributor by sharing the latest insights on the use of perf. My session, "perf In Action" focused on real-world applications of this powerful performance analysis tool. Anyone can find more details about my session here: https://debconf24.debconf.org/talks/43-perf-in-action-real-world-applications/

I'm GNU Linux Kernel contributor: https://lore.kernel.org/all/?q=Yunseong+Kim I recently ported the perf wiki to Markdown format: https://perfwiki.github.io/

My primary area of interest is the IBM's Z and Power architecture. I am particularly focused on Linux support for various non-Intel-based architectures, as well as emulation layers for open-source microarchitectures. My recent contributions include identifying security vulnerabilities in the IBM Z architecture's memory subsystem within the Linux Kernel, which were documented.

･ CVE-2024-42235: https://lore.kernel.org/linux-cve-announce/2024080740-CVE-2024-42235-efae@gregkh/ ･ CVE-2024-41021: https://www.cve.org/CVERecord?id=CVE-2024-41021

As a Debian lover, I am eager to contribute to the upstream Debian community. I am excited to leverage the skills and experience I’ve developed over the years to further enhance Debian’s support for a diverse range of architectures.

I'm also active uftrace contributor: https://github.com/namhyung/uftrace/commits/master/?author=yskelg
