It fails checksum when updating with Paru. Cleaning the cache solves it.

I was asked this:

Provide additional RCU stall debug information (RCU_CPU_STALL_CPUTIME) [N/y/?]

Maybe it's worth adding it to the config.

Applying patch bore-tuning-sysctl.patch...

Hunk #1 FAILED at 67.

There seems to be something wrong with bore-tuning-sysctl.patch, but I don't know how to fix this patch.

There are additional dependencies: flex and bison.

@ptr1337 thanks very much. The "y" at the end confused me a bit, I think I figured out some shell syntax

@wustdsh

Little example:

The "y" at the end, means it is default enabled.

_cachy_config=${_cachy_config-y}

If the "y" is away, it is disabled.

_cachy_config=${_cachy_config-}

You can also pass a variable to configure the settings on your own, for example:

env _cachy_config= _build_zfs=y makepkg -si

Without editing the PKGBUILD at all. Just go with the way, you want to

There is no "anything". Most variables are only "y" or " " (nothing) to disable. There is for llvm LTO: _use_llvm_lto , which should be set to none, thin or full. But it is explained inside of the PKGBUILD

wustdsh commented on 2023-12-20 16:01 (UTC)

I see that each build option has a preset variable, like _cachy_config=${_cachy_config-y} .Should I just modify PKGBUILD or use env _cachy_config-y=ANYTHING. sorry probably a dumb question

Sorry, needs another checksum bump

Hi there, error messages when LTO is selected (both full or thin)


  UPD     include/generated/compile.h
  CC      scripts/mod/empty.o
clang-15: error: optimization flag '-fexcess-precision=fast' is not supported [-Werror,-Wignored-optimization-argument]

It is compiling as usual without LTO.

Thanks in advance. Regards.

@ptr1337 LTO -> Full Compiling a kernel without LTO right now. I'll edit when tested.

Edit 1. Nope. Messages are gone compiling without LTO.
