While we are used to seeing Intel engineers dominating speaker lists at various Linux events around the world, it has been several years since AMD engineers have held as many presentations as they did this week at the Linux Plumbers Conference and now the Open-Source Summit in the EU is taking place in Dublin , Ireland.
AMD engineers regularly participate in the annual X.Org Developers Conference (XDC) with a talk or two to highlight improvements and/or new features that are being worked on with the Radeon graphics aspect. But when it comes to the AMD CPU side of the house, I can’t remember an event in a number of years where AMD held more than three conversations. Then again, personal events are slowly coming back and AMD’s market share continues to increase, particularly on the EPYC server side of the home which is obviously very important for Linux. But also thanks to design victories with the likes of Linux-powered Steam Deck, we’re starting to see a growing AMD presence at Linux events.
It’s a nice change from a number of years that often don’t see any AMD talks or if one’s recent lucky, compared to the occasional dozen or so Intel engineers presenting at Linux conferences and other open source events. It’s a comeback for AMD too since a decade ago during the times of AMD Fusion/HSA, they tended to speak at more events, cementing their efforts such as taking over MeeGo at the time, sponsoring Linux events, giving Opteron mouse pads using the GCC compiler tuning in. Flags on it, and many other AMD Linux engagements especially during the days of the defunct OS Research Center in Dresden.
Several Linux events are taking place this week in Dublin, Ireland, where AMD has increased its participation compared to previous years.
AMD engineers Gautham R Shenoy and Prateek Nayak presented at the Linux Plumbers conference about their work Split-LLC and user space hint for tasks, following the RFC patch thread sent out last week. This work, which they hope to eventually develop in some form, will further improve the performance of AMD EPYC servers on Linux. Those interested can see it PDF Slide Set A video recording of the talk is included below.
Meanwhile, AMD’s Ray Hwang introduced precise frequency control with kernel governors. This stems from AMD’s recent work on the P-State CPU frequency scaling driver and more recently a follow-up P-State EPP driver. there ship surface For those interested, video recording is not currently available.
Meanwhile, AMD’s Ashish Kalra gave a presentation on interrupt security in Linux with the AMD SEV-SNP. there that slide (PPTX) for those interested.
There were also other AMD-related talks at the Linux Plumbers conference where AMD was linked via Secure Encrypted Virtualization (SEV) and other technologies while talks were being held by its partners such as SUSE and Google.
In the meantime, the Open Source Europe Summit is now taking place in Dublin for the rest of the week with additional AMD talks. Edgar Iglesias spoke with AMD-Xilinx Combined QEMU and RTL open source simulationRay Hwang gave a second talk about AMD P-State driver voltage For the OSS Europe audience, spoken by Bruce Ashfield from AMD Included containers with Yocto.
It’s great to see significantly more AMD’s participation in Linux events while still not at the level of the likes of Intel/Google/Red Hat engineers in these events. It’s not just basic AMD participation but tech talks rather than marketing presentations/sponsor presentations/thin topics as some vendors frequently participate in LF events. It is in line with AMD’s increasing contributions to the major Linux kernel over the past two years or so particularly on the client and server sides to ensure timely hardware support, enable new features in Linux, etc. Hopefully all of this continues to go well and this is just the beginning of more good things to come from AMD on the open source/Linux interface.
