[$] A new swap abstraction layer for the kernel

1 év 3 hónap óta
Swapping may be a memory-management technique at its core, but its implementation also involves the kernel's filesystem and storage layers. So it is not surprising that a session on the kernel's swap abstraction layer, led by Chris Li at the 2024 Linux Storage, Filesystem, Memory-Management and BPF Summit, was held jointly by all three of those tracks. Li has some ambitious ideas for an improved subsystem, but getting to a workable implementation may not be easy.

[$] What's scheduled for sched_ext

1 év 3 hónap óta

David Vernet's second talk at the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit was a summary of the state of sched_ext, the extensible BPF scheduler that LWN covered in early May. In short, sched_ext is intended as a platform for rapid experimentation with schedulers, and a tool to let performance-minded administrators customize the scheduler to their workload. The patch set has seen several revisions, becoming more generic and powerful over time. Vernet spoke about what has been done in the past year, and what is still missing before sched_ext can be considered pretty much complete.

[$] The twilight of the version-1 memory controller

1 év 3 hónap óta
Almost immediately after the merging of control groups, kernel developers set their sights on reimplementing them properly. The second version of the control-group API started trickling into the kernel around the 3.16 release in 2014 and users have long since been encouraged to migrate, but support for (and users of) the initial API remain. At the 2024 Linux Storage, Filesystem, Memory-Management and BPF Summit, memory-management developers discussed whether (and when) it might be possible to remove the version-1 memory controller. The session was led by Shakeel Butt and (participating remotely) Roman Gushchin.

[$] Supporting larger block sizes in filesystems

1 év 3 hónap óta
In a combined storage and filesystem session at the 2024 Linux Storage, Filesystem, Memory Management, and BPF Summit, Luis Chamberlain led a discussion on filesystem support for block sizes larger than the usual 4KB page size, which followed up on discussion from last year. While the session was meant to look at the intersection of larger block sizes with atomic block writes that avoid torn (partial) writes (which was also discussed last year), it mostly focused on the filesystem side. Over time, the block sizes offered by storage devices have risen from the original 512 bytes; Chamberlain wanted to discuss filesystem support for block sizes larger than 4KB.
