Péter Ujfalusi
Linux Software Engineer at Intel Corporation
Tampere, Pirkanmaa, Finland
Summary
🤩
RockstarPéter Ujfalusi is a Linux software engineer with 15 years of deep kernel and embedded systems experience, currently working on open-source Linux audio (ALSA/ASoC/SOF) at Intel in Tampere. He has a strong track record at Nokia and Texas Instruments driving upstream ASoC and DMAengine support for multiple ARM SoC families and led TI’s DMA Data Movement Architecture from spec through pre-silicon. A prolific contributor to high-profile projects like the Zephyr RTOS, Sound Open Firmware and the mainline Linux tree, he specializes in low-level device drivers, DMA debugging and hardware-specific audio optimizations. Péter’s work often focuses on subtle hardware quirks—FIFO draining, sample container sizing and memory management—that improve real-world audio reliability across Intel and TI platforms. He combines hands-on bug hunting and refactoring with upstream maintenance, making him adept at turning vendor requirements into clean, upstreamable kernel code.
