[pve-devel] ZFS 0.8 and __kernel_fpu_{begin,restore} symbols

[Harald Leithner]

Hi,

I have seen zfs 0.8 has been merged in to the pve kernel master branch
including the update to Kernel 5.0.8 for buster.

Does the Ubuntu/PVE kernel export the __kernel_fpu symbols?
I ask because I didn't found a patch for this and it would be painful if
we have zfs with crypto without good performance.

The patch used by NixOS https://github.com/NixOS/nixpkgs/pull/61076
mentions a throughput drop of 1GB/s (200 instead of 1.2 GB/s) without
the exported symbols.

thx

Harald
