### Selecting the CPU scheduler | |
# ATTENTION - one of seven predefined values should be selected! | |
# 'bmq' - select 'BitMap Queue CPU scheduler' | |
# 'pds' - select 'Priority and Deadline based Skip list multiple queue CPU scheduler' | |
# 'cacule' - select 'CacULE scheduler' | |
# 'cacule-rdb' - select 'CacULE-RDB scheduler' | |
# 'bore' - select 'Burst-Oriented Response Enhancer' | |
# 'cfs' - select 'Completely Fair Scheduler' | |
# 'tt' - select 'Task Type Scheduler by Hamad Marri' | |
# 'hardened' - select 'BORE Scheduler hardened' ## kernel with hardened config and hardening patches with the bore scheduler | |
_cpusched='bore' | |
### BUILD OPTIONS | |
# Set these variables to ANYTHING that is not null to enable them | |
### Tweak kernel options prior to a build via nconfig | |
_makenconfig=y | |
# NUMA is optimized for multi-socket motherboards. | |
# A single multi-core CPU actually runs slower with NUMA enabled. | |
# See, https://bugs.archlinux.org/task/31187 | |
_NUMAdisable=y | |
# Compile ONLY used modules to VASTLYreduce the number of modules built | |
# and the build time. | |
# | |
# To keep track of which modules are needed for your specific system/hardware, | |
# give module_db script a try: https://aur.archlinux.org/packages/modprobed-db | |
# This PKGBUILD read the database kept if it exists | |
# | |
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed-db | |
_localmodcfg= | |
# Use the current kernel's .config file | |
# Enabling this option will use the .config of the RUNNING kernel rather than | |
# the ARCH defaults. Useful when the package gets updated and you already went | |
# through the trouble of customizing your config options. NOT recommended when | |
# a new kernel is released, but again, convenient for package bumps. | |

### Enable KBUILD_CFLAGS -O3 | |
_cc_harder=y | |
### Set performance governor as default | |
_per_gov=y | |
### Enable TCP_CONG_BBR2 | |
_tcp_bbr2=y | |
### Running with a 1000HZ, 750Hz, 600 Hz or 500Hz tick rate | |
_HZ_ticks=750 | |
## Choose between perodic, tickless idle or full tickless | |
### Full tickless can give higher performances in various cases but, depending on hardware, lower consistency. | |
_tickrate=full | |
## Choose between full(low-latency), voluntary or server | |
_preempt=voluntary | |
### Disable MQ-Deadline I/O scheduler | |
_mq_deadline_disable=y | |
### Disable Kyber I/O scheduler | |
_kyber_disable=y | |
### Enable multigenerational LRU | |
_lru_enable=y | |

# Other options : | |
# - "native_amd" (use compiler autodetection - Selecting your arch manually in the list above is recommended instead of this option) | |
# - "native_intel" (use compiler autodetection and will prompt for P6_NOPS - Selecting your arch manually in the list above is recommended instead of this option) | |
# - "generic" (kernel's default - to share the package between machines with different CPU µarch as long as they are x86-64) | |

# Or use the _use_auto_optimization with _use_auto_optimization=y | |

# "thin: uses multiple threads, faster and uses less memory, may have a lower runtime performance than Full." | |

## Change the thin lto cachedir for fixing building several dkms modules including zfs | |

# KCFI is a proposed forward-edge control-flow integrity scheme for | |
# Clang, which is more suitable for kernel use than the existing CFI | |
# scheme used by CONFIG_CFI_CLANG. KCFI doesn't require LTO, doesn't | |
# alter function references to point to a jump table, and won't break | |
# function address equality. | |
# ATTENTION!: you do need a patched llvm for the usage of kcfi, | |
# you can find a patched llvm-git in the cachyos-repo's. | |
# The packagename is called "llvm-kcfi" | |
_use_kcfi= | |
