 Posted: Tue Dec 20, 2022 6:14 pm Post subject: Any general advices ? Ryzen and make.conf and kernel config |
 |
|
Hello, it's me again.
So can I start this way ?
Please help how to configure kernel in order to install Gentoo on AMD 5500u ?
Last time I probably (or probably not) turned off some "intel" stuff, and
| Quote: | * Determining 'BEST' compression method for initramfs using kernel config '/usr/src/linux/linux-6.0.8-gentoo/.config' ...
* Checking if we can use 'XZ' compression ...
* Cannot use 'XZ' compression, kernel option 'CONFIG_RD_XZ' is not set!
* Checking if we can use 'LZMA' compression ...
* Cannot use 'LZMA' compression, kernel option 'CONFIG_RD_LZMA' is not set!
* Checking if we can use 'ZSTD' compression ...

* Checking if we can use 'BZIP2' compression ...
* Cannot use 'BZIP2' compression, kernel option 'CONFIG_RD_BZIP2' is not set!
* Checking if we can use 'LZO' compression ...
* Cannot use 'LZO' compression, the tool 'lzop' to compress initramfs was not found. Is app-arch/lzop installed?
* Checking if we can use 'LZ4' compression ...
* Cannot use 'LZ4' compression, the tool 'lz4' to compress initramfs was not found. Is app-arch/lz4 installed? |
How to avoid this mistake ?
What is safe regarding menuconfig to disable ?
Last time system just won't make images. Last time on intel cpu, I just can't install wifi modules.
I hope that this time will be better.
Any advices regarding make.conf ? |

RIA77,
DIY Kernels still describes the correct method.
The kernel has got a lot bigger in the 17 years since that past was made, so you need a lot more coffee now :)
Some of the detail has changed too.
It will help you to configure a kernel if you understand the boot process at a high level.
The understanding will help with the what and the why.
| Code: | * Checking if we can use 'XZ' compression ...
* Cannot use 'XZ' compression, kernel option 'CONFIG_RD_XZ' is not set! |
The kernel symbolmust be set to <*> for the kernel to read XZ compression ... and so on.
In make.conf, use
Set " Where X is the lowest of your thread count or
Set to whatever app-portage/cpuid2cpuflags tells you is right for your CPU.
If you want an all testing install, it mostly works but expect to pick up the pieces from time to time.

I have 12 threads, should I set MAKEOPTS="-j12 ?
Is it too dangerous ?
16 gigabytes of ram.

Where can I find option for XZ in kernel ? |

RIA77,
will be safe most of the time.
Bigger numbers will work less and less often.
Even at -j8 a few big packages may fail the RAM check, so you may want to tell portage to use a lower number of threads to build them.
You will know which ones when you find them.
Search for RD_XZ.
The CONFIG_ is not required.
