2024-09-19fragments: Add base/compressionWolfgang Müller-0/+1
For now this will only include support for zstd. This is generic enough to keep in a base profile.
2024-09-19Simplify handling of KVM-based optionsWolfgang Müller-0/+7
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.
2022-10-15fragments: Enable CONFIG_RANDSTRUCT_PERFORMANCEWolfgang Müller-0/+1
This option is now needed for Kernel Self Protection system to be available.
2022-07-10fragments: Remove reference to STRUCTLEAK_BYREFWolfgang Müller-1/+0
This option no longer exists in versions >= 5.18.7.
2022-07-10fragments: Enable sensors for drive temperaturesWolfgang Müller-0/+2
These are useful to show with lm-sensors. No more need to show temperatures using smartctl.
2022-07-10fragments: Enable core scheduling for SMTWolfgang Müller-0/+2
This should be safe to have enabled (but unused) and gives us an extra layer of potential mitigation of SMT side channels.
2022-07-10fragments: Enable X2APIC supportWolfgang Müller-0/+3
This should improve handling of very large core counts and should be safe to enable globally.
2022-07-10fragments: Add fragments for base ACPI settingsWolfgang Müller-0/+1
For now this enables the processor aggregator, which should reduce power consumption when supported by the ACPI device.
2022-07-10fragments: Add fragment for task accountingWolfgang Müller-0/+4
This is needed for application such as htop and doesn't hurt to be included in the base group.
2022-06-04fragments: Enable CONFIG_BINFMT_MISCWolfgang Müller-0/+2
2022-06-04fragments: Add CONFIG_JUMP_LABEL to base/commonWolfgang Müller-0/+2
This seems to be a harmless optimization.
2022-06-04fragments: Remove reference to CONFIG_UNUSED_SYMBOLSWolfgang Müller-2/+0
This option does no longer exist in the 5.15 branch.
2022-06-04fragments: Add requisite option for KSPWolfgang Müller-0/+1
2021-08-13fragments: Update to latest KSP recommendationsWolfgang Müller-0/+5
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.
2021-08-13fragments: Enable CONFIG_SECURITYWolfgang Müller-0/+2
An upcoming commit updates to the latest KSP recommendations and requires this particular setting as a direct dependency for CONFIG_SECURITY_YAMA.
2021-08-13fragments: Use expert mode by defaultWolfgang Müller-0/+2
An upcoming commit which updates to the latest KSP recommendations requires expert mode for one setting. Enable it here.
2021-07-20fragments: Remove obsoleted KSP switchWolfgang Müller-1/+0
The newer versions of sys-kernel/gentoo-sources do not have this switch anymore, instead relying only on the architecture-specific switches. Remove it.
2021-07-03fragments: Enable GENTOO_KERNEL_SELF_PROTECTIONWolfgang Müller-0/+3
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.

2021-03-06fragments: Enable CONFIG_RASWolfgang Müller-0/+1
This is needed for CONFIG_EDAC* but is not enabled by default upstream.
2021-03-06fragments: Remove superfluous options for 5.10Wolfgang Müller-1/+0
These options have either been merged into others or enabled unconditionally.
