NVIDIA RTX 30 Series Resizable BAR Support Continues Helping Performance On Linux

While NVIDIA has been supporting Resizable BAR for a while now with their GeForce RTX 30 series graphics cards, for those exclusively using Linux it remains more of a challenge due to AIB partners generally not releasing any vBIOS updates for ReBAR support that can be easily applied under Linux. But if you do carry out an update — such as under Windows — the performance uplift can be worthwhile if using a game that can benefit from the support.

FUTEX2 System Call Updated To Work On ARM

While Linux 5.15 has many new features and improvements, one of the patch series we have been eager to see land is the work introducing the new FUTEX2 system call. FUTEX2 can help improve the performance of newer Windows games running on Linux via Wine / Steam Play’s Proton by better matching the Windows kernel behavior, but while it didn’t land for Linux 5.15, at least a new version of the patches were posted…

Still-Pending AMD PSF Control Patch To Be Retailored For KVM

Of all the great stuff for AMD in Linux 5.15, one of the patches still not having yet been mainlined is the control support around Predictive Store Forwarding (PSF) with Zen 3 processors. It’s been six months since AMD published their security whitepaper around PSF while the Linux patch has yet to be mainlined while now it seems will be updated for a reduced focus on KVM usage…

Linux Developers Talk Again About An Accelerator Subsystem – Or Moving Them Into The GPU/DRM Area

On and off for years has been talk of an accelerator subsystem for the Linux kernel considering that for now most AI training/inference accelerator drivers end up lodged within the “char/misc” area of the kernel. That accelerator subsystem discussion has been restarted with talks of having such a subsystem or moving those drivers within the GPU/DRM subsystem space…

Linux 5.15 Is A Very Exciting Kernel For AMD

While working on my usual Linux kernel feature overview that summarizes the many articles over the past two weeks outlining all of the new features and changes merged, one area that particularly stands out for Linux 5.15 are all of AMD’s upstream contributions that happened to make it in this kernel. There is a lot of new enablement on the AMD side — both for CPUs and Radeon graphics — but also improving existing hardware support…

It's Looking Like Folios / Pagesets Might Miss Making It Into Linux 5.15

We are now down to the last day of the Linux 5.15 merge window and one of the patch series we have been waiting to see if it would land during this two week period was the “folios” code — or that also was recently renamed to “pagesets” to address some concerns over the name…
