New issue arrived. After switching to sd-boot from grub I can not generate boot menu entry for linux-cachyos-tt-lto. systemd-boot-manager is installed. Running sdboot-manage gen doesn't help. Kernel successfully compiles, installs, but menu entry is not generated. Other kernels from repository correctly generate boot menu entries. Hmm, please some guidance. What am I doing wrong? Maybe something in kernel config prevents menu entry generation? No idea. It was working with grub with no problem.

Thank You for your time and exhausted answer. I've tried "normal build" process and I've got an error:

makepkg -si
==> Making package: linux-cachyos-tt-lto 5.19.3-1 (Tue Aug 23 20:13:56 2022) ==> Checking runtime dependencies... ==> Checking buildtime dependencies... ==> Retrieving sources... -> Found linux-5.19.3.tar.xz -> Found config -> Found auto-cpu-optimization.sh -> Found 0001-cachyos-base-all.patch -> Found 0001-tt-cachy.patch ==> Validating source files with sha256sums... linux-5.19.3.tar.xz ...

Any idea what is wrong?

@miq

I don't see here a issue. It seems probably to be a issue from manjaro's pamac. The kernel is build successfully. You probably are able to install it with sudo pacman -U then the filenames where it got placed.

Personally I dont use manjaro and never used it. Maybe you should try instead of using "pamac build" the normal build process.

git clone https://aur.archlinux.org/linux-cachyos-tt.git
cd linux-cachyos-tt
nano PKGBUILD (changing parameters you wish)
makepkg -si

All kernels from CachyOS has been built fine on our buildserver. You can find them here: https://mirror.cachyos.org/repo/x86_64_v3/cachyos-v3/

You can also the install the kernels from there, if you add our keyring. Adding the complete repo is not a good idea, Ive never tested it against manjaro since we provide all packages with a optimized march (x86-64-v3)

For getting the keyring use:

sudo pacman-key --recv-keys F3B607488DB35A47 --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key F3B607488DB35A47

Then just install the package you want with:

sudo pacman -U 'https://mirror.cachyos.org/repo/x86_64_v3/cachyos-v3/linux-cachyos-tt-lto-5.19.2-1-x86_64_v3.pkg.tar.zst' 'https://mirror.cachyos.org/repo/x86_64_v3/cachyos-v3/linux-cachyos-tt-lto-headers-5.19.2-1-x86_64_v3.pkg.tar.zst'

If you want to build it yourself, just follow the steps above. It should work.

Forgot to mention I use Manjaro.

miq commented on 2022-08-16 10:16 (UTC)

Anyone?

I can not successfully compile this kernel with llvm/lto. It stucks on "cleaning up" Anyone help? This is my pkgbuild config file:

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='tt'

BUILD OPTIONS
Set these variables to ANYTHING that is not null to enable them
Tweak kernel options prior to a build via nconfig

_makenconfig=

Tweak kernel options prior to a build via menuconfig

_makemenuconfig=

Tweak kernel options prior to a build via xconfig

_makexconfig=

Tweak kernel options prior to a build via gconfig

_makegconfig=

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=y

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=

Enable TCP_CONG_BBR2

_tcp_bbr2=y

Running with a 1000HZ, 750Hz, 600 Hz or 500Hz tick rate

_HZ_ticks=750

Choose between perodic, idle or full
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=full

Disable MQ-Deadline I/O scheduler

_mq_deadline_disable=y

Disable Kyber I/O scheduler

_kyber_disable=y

Enable multigenerational LRU
ATTENTION - one of three predefined values should be selected!
'standard' - enable multigenerational LRU
'stats' - enable multigenerational LRU with stats
'none' - disable multigenerational LRU

_lru_config='standard'

Enable DAMON

_damon=y

Enable Linux Random Number Generator

_lrng_enable=y

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

_processor_opt=

_use_auto_optimization=y

disable debug to lower the size of the kernel

_disable_debug=y

Enable zram/zswap ZSTD compression

_zstd_compression=y

Selecting the ZSTD kernel and modules compression level
ATTENTION - one of two predefined values should be selected!
'ultra' - highest compression ratio
'normal' - standard compression ratio
WARNING: the ultra settings can sometimes
be counterproductive in both size and speed.

_zstd_level_value='normal'

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=full

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"
ATTENTION!: This is very experimental and could fail and the compilation or have other bugs in the kernel
