⚠️ ISDN is now Oldspeak

｢ Integrated Services Digital Network (ISDN) usage is long obsolete even where it had enjoyed some successes in the likes of Germany and Norway. With no activity in years to the ISDN and mISDN subsystem code for the Linux kernel, a patch was sent out today for orphaning the code ｣

｢ Linux has also been ported to itself. You can now run the kernel as a userspace application - this is called UserMode Linux (UML) ｣

The #Linux Boot Process: From Power Button to #Kernel

New #Project with my friends!

https://krnldev.nerdnextdoor.net/

We are making our own #OSDev / #KernelDev #Wiki. (We're aware of osdev.org and osdev.wiki.)

The wiki source is on #Codeberg. We aim to be a modern and reliable source for AARCH64 and x86_64 OSDev, documenting kernels and how they work so others can learn from them and being a friendly newcomer place.

We may do other architectures including 32-bit too but our main focus are the ones we picked.

🐧 Linux 6.19 Will Add Support For The Logitech G13 Keypad - 17 Years After Hardware Debut - Phoronix

｢ Logitech G13 Linux support patch was posted for the G13 with its 25 programmable keys, mini joystick, and other functionality. There had been out-of-tree support for the Logitech G13 via the open-source community but now this patch is working its way to rhe mainline Linux kernel ｣

Namjae Jeon from exFAT and KSMBD fame published a new #NTFS #Linux #kernel driver called #NTFSPLUS

https://lore.kernel.org/lkml/20251020020749.5522-1-linkinjeon@kernel.org/

""Currently, ntfs support in Linux was the long-neglected NTFS Classic (read-only), which has been removed from the Linux kernel, leaving the poorly maintained ntfs3. ntfs3 still has many problems and is poorly maintained, so users and distributions are still using the old legacy ntfs-3g.

What is ntfsplus?

The remade ntfs called ntfsplus is an implementation that supports write and the essential requirements(iomap, no buffer-head, utilities, xfstests test result) based on read-only classic NTFS. The old read-only ntfs code is much cleaner, with extensive comments, offers readability that makes understanding NTFS easier. This is why ntfsplus was developed on old read-only NTFS base. The target is to provide current trends(iomap, no buffer head, folio), enhanced performance, stable maintenance, utility support including fsck.""

When is the next Linux kernel release? What about vX.Y? When is the next merge window? When is the deadline for features for kernel version vX.Y?

Get asked this a lot?

Point the people at this web page for about as accurate answers as anyone's going to be able to give.

The Linux Kernel Tea Leaves is a reimagination of the venerable PHB Crystal Ball, with even more answers based on fewer stats.

Oh no. It's true: The mouse cursor image on Wayland is delayed by one frame. 😭

Proof: https://mort.coffee/home/wayland-input-latency/

Great explaination by @lina: https://lobste.rs/s/oxtwre/hard_numbers_wayland_vs_x11_input_latency#c_edq7tn

A failed attempt to fix this in @gnome: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4249

It sounds like there is going to be a new kernel API that would allow updating the cursor independently and therefore earlier, but I couldn't find anything about that.

There is now a dedicated drm-rust #Linux tree for Rust DRM #kernel drivers and infrastructure:

https://lore.kernel.org/dri-devel/20250901202850.208116-1-dakr@kernel.org/t/#u

"[…] Multiple DRM Rust drivers (e.g. nova-core, nova-drm, Tyr, rvkms) are in development, with at least Nova and (soon) Tyr already upstream. Having a shared tree will ease and accelerate development, since all drivers can consume new infrastructure in the same release cycle. […]""

- completed 64 bit support
- all disk drivers running in userland (⇒ you can live-debug a disk driver with gdb)
- Rust support
- working disk and CD-ROM via USB (this actually is a big deal)
- SMP (multiprocessing) is finally working well
- custom keyboard layouts on the console via xkb

#FreeSoftware #kernel

Avui fa 34 anys del neixement del #kernel de Linux. 👏 Linus Torvalds, el seu creador, el feia públic per correu electrònic:

https://mastodon.social/@nixCraft/115088303518406584

Internet funciona principalment gràcies a Linux i el seu kernel.

Linus QOTD from a recent #Linux #kernel merge commit:

""I am on a mission to write out the more obscure TLAs in order to keep track of them.

Because while math tells us that there are only about 17k different combinations of three-letter acronyms using English letters (26^3), I am convinced that somehow Intel, AMD and ARM have together figured out new mathematics, and have at least a million different TLAs that they use.""
