Linux 6.5 has many great features from the AMD P-State EPP driver default rather than ACPI CPUFreq for Zen 2 and newer supported AMD Ryzen systems, initial USB4 v2 enablement, initial MIDI 2.0 kernel driver work, more Intel hybrid CPU tuning, and a whole lot more.
Hopefully bcachefs will be merged with 6.6.
For those who may not know, bcachefs (bcachefs.org) was written by the same developer as bcache (wikipedia.org) - TIL! I was always confused when reading headlines about bcachefs but never looked into why someone might give their filesystem such a conflicting name. Now it makes sense. I’ve used bcache briefly and it worked really well for my use case. Anyone using bcachefs that can speak to their own experience? How does it compare to btrfs?
I love it. I have a pool of 9x10tb spinning rust as bulk storage (background target in bcachefs terms) and 6x3.84tb SSD as cache and metadata (foreground, promote, metadata targets). It’s proven to be incredibly solid, I’ve written tons (on the order of 50+tb) to the FS and actually hit a few edge cases during my early testing in terms of scaling limits and the like.
This ~100Tb array replaced a Synology-flavoured btrfs 30Tb which had been running up against capacity limits for a while. I looked into alternative FSes: btrfs RAID wasn’t quite there for me, and zfs won’t be mainlined.
The only ‘not 100% stable’ feature is Erasure Coding, which I look forward to enabling at some point in the future.
wow! happy to hear that. May have to play around with it before I fully commit.
The new EEVDF scheduler would also be nice.
