### 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=
# 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.
_use_current=
### 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
## Enable DAMON
_damon=y
## enable SPECULATIVE_PAGE_FAULT

# CPU compiler optimizations - Defaults to prompt at kernel config if left empty
# AMD CPUs : "k8" "k8sse3" "k10" "barcelona" "bobcat" "jaguar" "bulldozer" "piledriver" "steamroller" "excavator" "zen" "zen2" "zen3"
# Intel CPUs : "mpsc"(P4 & older Netburst based Xeon) "atom" "core2" "nehalem" "westmere" "silvermont" "sandybridge" "ivybridge" "haswell" "broadwell" "skylake" "skylakex" "cannonlake" "icelake" "goldmont" "goldmontplus" "cascadelake" "cooperlake" "tigerlake" "sapphirerapids" "rocketlake" "alderlake"
# 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

# Clang LTO mode, only available with the "llvm" compiler - options are "no", "full" or "thin".
# "full: uses 1 thread for Linking, slow and uses more memory, theoretically with the highest performance gains."
# "thin: uses multiple threads, faster and uses less memory, may have a lower runtime performance than Full."
_use_llvm_lto=
# 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=
