While mostly of benefit to server administrators with large fleets of hardware, Linux 6.1 aims to make it easier to help spot problematic CPUs/cores by reporting the likely socket and core when a segmentation fault occurs, which can help in spotting any trends if routinely finding the same CPU/core is causing problems...

Async page flipping via DRM_MODE_PAGE_FLIP_ASYNC has been available with the Direct Rendering Manager's legacy API but hasn't been supported by the atomic mode-setting interface. However, a proposed patch series would add that atomic async flip support and wire it up initially for the AMDGPU DRM driver. Meanwhile Valve's Gamescope compositor in user-space would be ready to make use of it...

They've pulled that off and the code is now out there in a public GitHub repository...

The current Intel open-source "ANV" Vulkan driver within Mesa supports graphics hardware going back to the "Gen7" graphics found with Ivy Bridge / Haswell. However, Intel open-source Linux graphics driver engineers are preparing to separate the old Ivy Bridge / Haswell (Gen7) and Broadwell (Gen8) graphics into a separate Mesa driver so they can better focus on improving their modern Vulkan driver that would then be limited to Skylake Gen9 graphics and newer...

The X.Org project "xisxwayland" is out with a new version of this simple program that can be easily called by shell scripts and other simple uses for checking to see whether the running X.Org Server is a genuine X11 server or more commonly these days an XWayland server running within a Wayland environment...

For speeding up the actual Mesa continuous integration (CI) process itself with frequently building new revisions of Mesa3D, their CI infrastructure is beginning to make use of the Mold linker as a high performance alternative to the GNU Gold and LLVM LLD linkers. This is yielding a "substantial" performance improvement in tests for being able to turnaround CI jobs faster and in turn allowing Mesa developers to be more efficient...

Open-source firmware consulting firm 3mdeb last year worked on Fwupd support for FreeBSD so system firmware updates can be more easily handled on that popular BSD operating system and leveraging the Fwupd/LVFS infrastructure that's been happening for years in the Linux space. Their most recent target is now DragonFlyBSD for handling of UEFI firmware updates with Fwupd...

One of the great things about Jason Ekstrand having joined Collabora at the start of the year is that the former Intel graphics engineer, who was on the team that created their original Vulkan driver, can now work on whatever open-source driver code he wishes. Among other upstream Mesa work, he's recently been contributing to the new "NVK" NVIDIA Vulkan driver and also the RADV driver too...

With this weekend having seen more Zink refactoring code land and Zink being faster than RadeonSI at least for some operations, it was time to fire up some fresh benchmarks of this generic OpenGL-on-Vulkan implementation. From the newest Mesa code this weekend after the latest Zink patches were merged, here is a look at how the Zink performance is compared to the RadeonSI Gallium3D driver's native OpenGL support. All of the testing was done using an AMD Radeon RX 6800 XT graphics card.

For the past decade going back to the early GTK3 days there has been the "Broadway" back-end that allows for GTK interfaces to be rendered within HTML5 web browsers. Aside from demos and other toys, there hasn't been too much widespread use reported with this GTK HTML5 back-end and some distributions like Ubuntu and Debian haven't been shipping the Broadway support with the newer GTK4. However, that is changing now for Debian and with this autumn's release of Ubuntu 22.10...

Made public back in June by Intel was the MMIO Stale Data vulnerabilities. The disclosure noted affected Intel products range from Haswell up through Rocket Lake on the client side or Xeon Scalable Ice Lake servers. However, pre-Haswell Intel CPUs might be impacted too while the Linux kernel to this point was incorrectly stating older CPUs are "not affected" by MMIO Stale Data...

With Intel Xeon Sapphire Rapids expected to make more of a splash coming up, it's a good time to revisit the Intel Xeon Platinum 8380 "Ice Lake" performance to see how the Linux software performance has evolved since last year's launch.
