# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
<qyliss>
aww
<samueldr>
that's where having the reasoning explained would be helpful :)
<samueldr>
oh
<samueldr>
>> Selecting this option will enable a DMAR device at boot time if one is found. If this option is not selected, DMAR support can be enabled by passing intel_iommu=on to the kernel.
<qyliss>
wow, according to repology we're the only ones to package rc kernels
<qyliss>
the upstream default is Y IIRC
<samueldr>
is there an issue with passing the intel_iommu=on flag?
<samueldr>
I should have looked at what the option did first :)
<samueldr>
I thought it served to enable the IOMMU feature
<samueldr>
(or _a_ feature of)
<qyliss>
it's slightly annoying, and also means users don't get the security properties of IOMMU by default
<samueldr>
hmmm, but since you say upstream defaults to =y it just blurs things even further!
<qyliss>
(ngl though my main motivation here is the "slightly annoying" part0
<qyliss>
looks like changing the default isn't the right thing to do, then
<qyliss>
but I'll keep thinking about the comparison site idea -- feels like it would be very useful and not too difficult
<samueldr>
yeah, while it would be better to have more insight from other distros, at a glance from the defconfig, archlinux and fedora, sounds like it's not desirable
<samueldr>
the most difficult part is finding the source of the config files :)
<qyliss>
i did find a debian bug report where they enabled it
<samueldr>
though maybe extracting from a kernel binary is the easiest universal way
<samueldr>
since NixOS *also* does not ship a .config file
<qyliss>
was thinking about that, but we also don't have a stable URL where one can download the latest kernel binary
<samueldr>
would be interesting, too, to include two columns from kernel.org: "no defconfig" and "defconfig"
<qyliss>
yeah
<qyliss>
Debian enabled it in 2019, no idea if it's still enabled
<samueldr>
yeah, there won't be a stable url for any distros, but you could go from the hydra path in one hope to get the nix store path
<samueldr>
one hop*
<samueldr>
with the "last build from a finished eval" link
<qyliss>
shame repology doesn't do binary package URLs
