* gen_configkernel: Prepare for kernel-6.64.3.9Michal Privoznik2024-01-191-6/+10
| | | | | | | | | | | | | | | | The microcode related config options were removed in [1] and microcode loading is enabled when support for corresponding CPU is enabled. Basically, this is equivalent to renaming options: CONFIG_MICROCODE_AMD -> CONFIG_CPU_SUP_AMD CONFIG_MICROCODE_INTEL -> CONFIG_CPU_SUP_INTEL Reflect this change in gen_configkernel.sh.

* firmware: copy only the necessary firmware(s) into initramfsDmitry Baranov2023-08-301-7/+0
| | | | | | | | | | | | | | | | | | | FIRMWARE=yes behavior is changed: Only the minimum number of firmware files will be copied. The list is generated using the `modinfo -F firmware [modules]...` command. The ability to copy all firmware(s) is also available with a new ALLFIRMWARE setting (see the modified genkernel.conf for more details). As for changes in the source code: gen_moddeps.sh: Significantly redesigned module list generation. To get a list of modules, use the `mod_dep_list()` function instead of `gen_dep_list()`. Modules that are not in the kernel (=n or invalid) will be filtered out. Aliases will be replaced with real names (including dependencies).

* Refactor (compressed) kernel module handlingThomas Deutschmann2021-09-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | To support a specific module compression algorithm, two things are needed: Used depmod utility on host system building the kernel must support chosen module compression algorithm to generate proper modules.dep file or genkernel would be unable to read module dependencies when copying modules to initramfs. At runtime, used modprobe utility must be able to handle chosen module compression algorithm or modules would be unloadable. To address the first requirement, genkernel will now check if used kmod utility on host system supports chosen module compression algorithm. To address the runtime requirement, this commit will switch from BusyBox's modutils implementation to kmod because BusyBox does not support ZSTD compression (yet).

* gen_configkernel.sh: config_kernel(): Warn when kernel config did not changeThomas Deutschmann2021-03-191-0/+9
| | | | | | | | | | | | When user requests to modify kernel config, i.e. `genkernel --menuconfig` but kernel config did not change, show a warning to allow user to notice. This can happen for example when user loaded a different kernel config in dialog but forgot to save to $KERNEL_OUTPUTDIR/.config which is required in that case.

For this run, even when --integrated-initramfs is set, the kernel option CONFIG_INITRAMFS_SOURCE should be unset *when* we are also tasked to create an initramfs.

* Change kernel and initramfs default filename in $BOOTDIRThomas Deutschmann2019-07-291-1/+1
| | | | | | | | | | | | | | | | | | This commit will change default kernel and initramfs filename: kernel-genkernel-%%ARCH%%-%%KV%% -> vmlinuz-%%KV%% System.map-genkernel--%%ARCH%%-%%KV%% -> System.map-%%KV%% initramfs-genkernel-%%ARCH%%-%%KV%% -> initramfs-%%KV%%.img The new naming will be consistent with kernel's "make install" and will allow to match files in /lib/modules with actual kernel. In addition, $ARCH value was moved to kernel's LOCALVERSION. This will ensure that this information is still present and when you do cross-compilation, that /lib/modules content don't get mixed.
