Going through my usual scanning of all the "-next" Git subsystem branches of new code set to be introduced for the next Linux kernel merge window, a very notable addition was just queued up... Linux 6.10 is set to merge the NTSYNC driver for emulating the Microsoft Windows NT synchronization primitives within the kernel for allowing better performance with Valve's Steam Play (Proton) and Wine of Windows games and other apps on Linux.

I was wondering if this can be used outside of Windows context.

Edit: I'm asking specifically for Linux context.

Why not? Would you rather that we have a Windows-exclusive subsystem in our kernel?

[-] uis@lemm.ee 5 points 7 months ago
  1. Kernel devs then would want to make it stable API. I don't want Windows API being stable part of kernel.

  2. It mostly implements racy stuff like pulsing event.

  3. There is already known subsystem that does not have stable API because it is used by only one project - DRI.

Backwards compatibility is important

How does that have to do with the sync primitive?

[-] ProgrammingSocks@pawb.social 1 points 7 months ago* (last edited 7 months ago)

Since it's a new feature, would it not cause incompatibility for any kernel versions before it was added?

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
