    So yeah, it kind of is a sign of good open source support, that their very early pre-release code is already in the kernel. It just needs to be fixed up before the actual release.

    Better that than getting added a few months after release and still needing to get fixed.
    Totally irrelevant. It doesn't change the fact that the process was so fucked up end to end.

    More like a bad sign of broken open source process. Quite embarrassing.

    Not really. If it was added a few months later it wouldn't have been broken.

    There are some engineering disasters along the way, but I guess the overall picture is still decent enough?!

    And here I thought Intel was always the best at contributing to the Linux kernel/community? At least that's what I always read in the Phoronix comments………

    Phoronix: Linux Disables Intel's New ENQCMD Feature Since Kernel Code "Broken Beyond Repair"

    For two years now we have seen various open-source patches around ENQCMD instructions for the code compilers and the Linux kernel. This Enqueue Stores support is part of Intel's Data Streaming Accelerator coming with Xeon Scalable "Sapphire Rapids". But even with Sapphire Rapids not launching until later this year, the already merged Linux kernel code is force-disabling the ENQCMD instructions support as the current kernel support is deemed "broken beyond repair" and will need to be reworked...
