    John posted v3 of the patch-set with the "remaining pieces of the #printk rework" to support threaded console printing, which is last big missing piece missing to support #realtime with the mainline #Linux #kernel through #PREEMPT_RT:

    They joys of bugs in hardware or firmware[1]:

    A user reported updating to 6.4.y broke on a Intel 3165 NIC. Bisection identified 5fc3f6c90cc ("r8169: consolidate disabling ASPM before EPHY access") as culprit.

    Turns out it was not a faulty bisection, as it seems enabling on some chips supported by can harm other PCI devices. 🥴 🤨

    Lai Jiangshan posted a RFC patch-set introducing a new hypervisor called :

    lore.kernel.org/lkml/202402261

    "'"This RFC series proposes a new virtualization framework built upon the hypervisor that does not require hardware-assisted virtualization techniques.

    So the over-arching goals of PVM are to 1) enable nested virtualization within any IaaS clouds […] 2) avoid costly exits to the host hypervisor […]"'"

    The last step in the rework saga (the last big pre-requisite before can be mainlined) is getting closer:

    John submitted the printk patch series "add threaded printing + the rest", which '"provides the remaining pieces of the printk rework. All other components are either already mainline or are currently in linux-next. […] Note that this series does *not* provide an nbcon console driver. That will come in a follow-up series."'

    ```The IA64 port of Linux has no maintainer, and according to a report from its only remaining user [0], it has been broken for a month and nobody cares.

    ```In this round, we've added two features: F2FS_IOC_START_ATOMIC_REPLACE and a per-block age-based extent cache.

    F2FS_IOC_START_ATOMIC_REPLACE […] guarantees a per-file atomicity […] more efficient […]

    The per-block age-based extent cache […] keeps the per-block age in a file, so that block allocator could split the hot and cold data blocks more accurately.```

    Another step closer for support in the upstream :

    The patch series "wire up write_atomic() printing"[1] is now in -next[2] and thus slated for inclusion in 6.11. 🥳

    Note, that series does _not_ include threaded printing or nbcon
    drivers. Those features will be added in separate follow-up
    series.

    Another small step to get aka aka support mainlined was taken, as more preparations for introducing kthreads were merged for 6.7: git.kernel.org/torvalds/c/2a80

    That work comes from this series:
    lore.kernel.org/all/2023091619

    But some more work is needed to finally make the printk stack be rt capable, as threaded printing, atomic printing regions, or nbcon drivers are still missing afaics.
