Alpine Linux

[JamiKettunen]

On top of using ln -s instead of making relative symlinks won't you have to fix the instances where $(SYMLINK) was used like from:

$(SYMLINK) Makefile $(BUILD)/Makefile

to:

$(SYMLINK) $(PWD)/Makefile $(BUILD)/Makefile

in https://github.com/cyring/CoreFreq/blob/develop/Makefile#L109, so that $(BUILD)/Makefile won't be a broken symlink? $(HW)/corefreqk.c below also would need the $(PWD)/ prefix

@JamiKettunen

Based on Virtual x86_64 alpine-virt-3.18.3-x86_64.iso

Host [Arch Linux 6.5.4]

qemu-system-x86_64 -enable-kvm -cpu max,hv-runtime -m 2G -smp 4 -cdrom alpine-virt-3.18.3-x86_64.iso

Once VM booted, the following packages have been installed

• Configure Networking
• Alpine Package Keeper

apk add nano git make gcc musl-dev linux-headers

CoreFreq Makefile is also fixed for symbolic links

git clone -b develop https://github.com/cyring/CoreFreq.git
cd CoreFreq
nano Makefile

SYMLINK ?= ln -s

Now try to build.
You may have to force clean

rm -fr build
make

Missing kernel module: to be continued

[cyring]

• Alpine is now installed to disk to ease Linux Kernel Headers

apk update
apk upgrade
apk add linux-virt-dev
reboot

• CoreFreq is now build and run from a standard user

cd ~/src/CoreFreq
nano Makefile

SYMLINK ?= ln -s

prepare:
        @if [ ! -e $(BUILD)/Makefile ]; then \
                $(SYMLINK) $(PWD)/Makefile $(BUILD)/Makefile; \
        fi

rm -fr build
make

• Need to rebuild a custom kernel ...

[cyring]

Custom Kernel

apk add alpine-sdk sed installkernel bc nawk diffutils findutils pahole openssl-dev python3 linux-virt linux-virt-dev

• Clone the aports tree

git config --global user.name "Your Full Name"
git config --global user.email "[email protected]"
git clone https://gitlab.alpinelinux.org/alpine/aports

• Fix write mode of /var/cache/distfiles/
• Create User keygen
• Add User to group abuild
• Create a branch for custom kernel

# addgroup <yourusername> abuild
abuild-keygen -a -i
cd aports
git checkout -b corefreq-kernel
cd main/linux-lts
cp -vi virt.x86_64.config .config
nano APKBUILD

_flavor-virt

abuild -rd

@JamiKettunen
With your Makefile changes, can you now build and run CoreFreq ?
Can you show the UI with its kernel window and the view in Tasks mode ?

[cyring]

No more work

[cyring]

• New parallel build

• Symlinks
