We don't want to have zstd compression on every machine, so get this
particular option out of the base/ directory. For now wee only use this
on albatross.
|
|
|
|
|
| |
For now this will only include support for zstd. This is generic enough
to keep in a base profile.
|
|
|
|
|
|
| |
Where before we had a profile/vm fragment that was set on nearly every
host we administer, now make sure to enable KVM unconditionally and put
CPU-specific KVM options into the CPU profiles.

This option is now needed for Kernel Self Protection system to be
available.
|
|
|
|
| |
This option no longer exists in versions >= 5.18.7.

These are useful to show with lm-sensors. No more need to show
temperatures using smartctl.

This should be safe to have enabled (but unused) and gives us an extra
layer of potential mitigation of SMT side channels.
|
|
|
|
|
| |
This should improve handling of very large core counts and should be
safe to enable globally.
|
|
|
|
|
| |
For now this enables the processor aggregator, which should reduce power
consumption when supported by the ACPI device.

This is needed for application such as htop and doesn't hurt to be
included in the base group.
|
| |
|
|
|
|
| |
This seems to be a harmless optimization.
|
|
|
|
| |
This option does no longer exist in the 5.15 branch.

The Gentoo KSP recommendations have changed slightly again, now
requiring three different settings instead of just one. Additionally, in
order to enable KSP at all, CONFIG_MODIFY_LDT_SYSCALL needs to be unset.
|
|
|
|
|
|
| |
An upcoming commit updates to the latest KSP recommendations and
requires this particular setting as a direct dependency for
CONFIG_SECURITY_YAMA.
|
|
|
|
|
| |
An upcoming commit which updates to the latest KSP recommendations
requires expert mode for one setting. Enable it here.

The newer versions of sys-kernel/gentoo-sources do not have this switch
anymore, instead relying only on the architecture-specific switches.
Remove it.

This setting pulls in a set of recommended settings [1] from the Kernel
Self Protection Project. We are pretty sure that we exhaustively set all
these manually already, but since Gentoo upstream provides this option,
make use of it too.

This is needed for CONFIG_EDAC* but is not enabled by default upstream.
|
|
|
|
|
| |
These options have either been merged into others or enabled
unconditionally.
