Intel GPUs from the consumer desktop Arc Graphics hardware to the Intel Data Center Flex GPU Series "Arctic Sound M" and forthcoming Xe HPC Ponte Vecchio are built around fully open-source drivers. A common misconception or confusion I've heard many times over the past number of months has been questioning whether Intel's discrete GPU driver support on Linux is open-source or is closed-source, etc. Well, it's fully open-source aside from the usual firmware caveat and running on Linux. Here is some initial commentary with running the Intel Arc Graphics A380 on Linux!

Lutris as the open-source game manager that integrates with the likes of Steam, GOG, Humble Bundle, and other game collections and emulators is out with a new update...

Brought up back in 2020 was the readfile system call for efficiently reading small files with the intention of it being simple for reading small files such as those via sysfs, procfs, and similar file-systems. The readfile patches were re-based yesterday against the current Linux 6.0 state, leaving hope that the new system call might finally be sent in for the next kernel cycle...

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.
