Instalar kernel for Debian

Instalando kernel package for Debian

Download build tools

sudo apt install build-essential bison flex gnupg libncurses-dev libelf-dev libssl-dev wget

gpg --locate-keys torvalds@kernel.org gregkh@kernel.org

Preparando e baixando o Kernel source

mkdir ~/kernel; cd ~/kernel
wget https://cdn.kernel.org/pub/linux/kernel/v .xz
wget https://cdn.kernel.org/pub/linux/kernel/v .tar.sign

Verificando a signature

unxz -c linux-v .tar.xz | gpg --verify linux-v .tar.sign -

tar xvf linux- .tar.xz
cd linux-v

Configurando

Rather than configure everything from scratch, copy the /boot/config-VERSION of the kernel currently in use to the kernel source directory

cp /boot/config-$(uname -r) .config

Use um dos métodos:

1. sudo make nconfig

2. sudo make oldconfig

3. sudo make olddefconfig

System keys

Disative o SYSTEM_TRUSTED_KEYS e SYSTEM_REVOCATION_KEYS em .config

scripts/config --disable SYSTEM_TRUSTED_KEYS
scripts/config --disable SYSTEM_REVOCATION_KEYS

sem isso vai ter erro do tipo:

make[4]: *** No rule to make target ‘debian/certs/debian-uefi-certs.pem’, needed by ‘certs/x509_certificate_list’. Stop.

Disative o debug

Disable DEBUG_INFO 

scripts/config --disable DEBUG_INFO

Se precisar usar o antigo enable DEBUG_INFO_NONE …

cripts/config --enable DEBUG_INFO_NONE

Compile o Kernel

make clean
make deb-pkg LOCALVERSION=-custom

Instale

ls -l ../*.deb

../linux-headers-V-custom_V-custom-1_amd64.deb ../linux-image-V-custom_V-custom-1_amd64.deb ../linux-libc-dev_V-custom-1_amd64.deb

Instale os pacotes (linux-libc-dev* não ) …

$ sudo dpkg -i ../linux-image-V-custom_5.19.8-custom-1_amd64.deb $ sudo dpkg -i ../linux-headers-V-custom_V-custom-1_amd64.deb

Reboot!!!
