Check your system for support > [!CAUTION] > Before enabling any of these repos, make sure that your system supports the level of functionality you want to > enable (e.g. `x86-64-v3`). > **If you don't check first, you may not be able to boot your system and will have to downgrade any packages you may have upgraded.** Check which feature levels your CPU supports with ```bash /lib/ld-linux-x86-64.so.2 --help ``` Example output snippet for a system supporting up to `x86-64-v3`: ``` Subdirectories of glibc-hwcaps directories, in priority order: x86-64-v4 x86-64-v3 (supported, searched) x86-64-v2 (supported, searched) ``` > [!NOTE] > ALHP repos for `x86-64-v2`, `x86-64-v3` and `x86-64-v4` are currently available. You can see all available > repositories [here](https://alhp.dev/). ### 2. Install keyring & mirrorlist Install [alhp-keyring](https://aur.archlinux.org/packages/alhp-keyring/) and [alhp-mirrorlist](https://aur.archlinux.org/packages/alhp-mirrorlist/) from the **AUR**. Example with `yay`: ```bash yay -S alhp-keyring alhp-mirrorlist ``` `alhp-keyring` provides the current signing keys used by ALHP, `alhp-mirrorlist` a selection of mirrors. ### 3. Choose a mirror (optional) Edit `/etc/pacman.d/alhp-mirrorlist` and comment in/out the mirrors you want to enable/disable. By default, a CDN mirror provided by ALHP is selected. > [!NOTE] > `cdn.alhp.dev` and `alhp.dev` are provided directly by ALHP. If you have problems with a mirror, > open an issue at [the mirrorlist repo](https://somegit.dev/ALHP/alhp-mirrorlist). ### 4. Modify pacman.conf Add the ALHP repos to your `/etc/pacman.conf`. Make sure the appropriate ALHP repository is **above** the Archlinux repo. Example for `x86-64-v3`: ```editorconfig [core-x86-64-v3] Include = /etc/pacman.d/alhp-mirrorlist [core] Include = /etc/pacman.d/mirrorlist [extra-x86-64-v3] Include = /etc/pacman.d/alhp-mirrorlist [extra] Include = /etc/pacman.d/mirrorlist # if you need [multilib] support [multilib-x86-64-v3] Include = /etc/pacman.d/alhp-mirrorlist [multilib] Include = /etc/pacman.d/mirrorlist ``` Replace `x86-64-v3` with the x86-64 feature level you want to enable. > [!TIP] > Multiple layers can be stacked as described in https://somegit.dev/ALHP/ALHP.GO/issues/255#issuecomment-3335. ### 5. Update package database and upgrade ``` pacman -Suy ``` ## FAQ ### Remove ALHP packages To disable ALHP, remove all *x86-64-vX* entries in `/etc/pacman.conf` and remove `alhp-keyring` and `alhp-mirrorlist`. After that, you can update pacman's databases and downgrade all packages, like ``` pacman -Suuy ``` ### LTO Enabled for all packages built after 04 Nov 2021 12:07:00 UTC. [More details.](https://somegit.dev/ALHP/ALHP.GO/issues/52) LTO status is visible per package on the package status page. ### Linux Kernel packages `KCFLAGS`/`KCPPFLAGS` are used to build the kernel packages with our additional flags. ### Directly linked kernel modules Due to our increase in pkgrel, building the kernel packages **will break any directly linked modules** such as `nvidia` (not `nvidia-dkms`) or `virtualbox-host-modules-arch` (not `virtualbox-host-dkms`). **Their respective `dkms`-variant is not affected**. This issue is being tracked in #68, a solution is being worked on. ### Mirrors You want to mirror ALHP? You are welcome to do so, [see alhp-mirrorlist for how to become one](https://somegit.dev/ALHP/alhp-mirrorlist#how-to-become-a-mirror). ### What packages are built Packages [excluded](https://www.reddit.com/r/archlinux/comments/oflged/alhp_archlinux_recompiled_for_x8664v3_experimental/h4fkinu?utm_source=share&utm_medium=web2x&context=3) from building (besides all `any` architecture packages) are being listed in issue #16. See also [package status page](https://status.alhp.dev) (search for `blacklisted`). ### Why is package X not up-to-date Also relevant for: **I can't find package X / Application X fails to start because it links to an old/newer lib** ALHP builds packages **after** they are released in the official Archlinux repos (excluding `[*-testing]`). This will cause packages to be delayed if the current batch contains many packages, or packages that take a while to build (e.g. `chromium`). You can always check on the progress of the current build cycle on the [package status page](https://status.alhp.dev). Please refrain from opening issues caused by packages currently in queue/not yet build/not yet moved to the repo. Please keep in mind that large rebuilds such as `openssl` or `python` can take days to complete on our current build hardware. ### Debug symbols ALHP provides a debuginfod instance under `debuginfod.alhp.dev`. To use it, have `debuginfod` installed on your system and add it to your `DEBUGINFOD_URLS` with: ```bash echo "https://debuginfod.alhp.dev" > /etc/debuginfod/alhp.urls ``` ### Switch between levels If you want to switch between levels, e.g. from `x86-64-v3` to `x86-64-v4`, you need to revert to official packages first, and then enable your desired repos again. 1. Comment out or remove the ALHP repo entries in `/etc/pacman.conf`. 2. Downgrade packages with `pacman -Suuy`. 3. Clear pacman's package cache with `pacman -Scc`. 4. Uncomment/add your desired repos to `/etc/pacman.conf` and update with `pacman -Suy`. ## Matrix For any non-issue questions, or if you just want to chat, ALHP has a Matrix room [here](https://matrix.to/#/#alhp:ofsg.eu) (`#alhp@ofsg.eu`). You can also find me (@idlegandalf) in `#archlinux:archlinux.org`. ## Donations I appreciate any money you want to throw my way, but donations are strictly optional. Donations are primarily used to pay for server costs. Also consider [donating to the **Archlinux Team**](https://archlinux.org/donate/), without their work ALHP would not be possible.
