ALHP x86-64-v3 official support and user experiences

MS1 · 2023-12-30 11:44:09

I know Arch can have repos with newer CFLAGS like -march=x86-64-v3 but this has not been adopted yet. ALHP is a project offers such packages. Are anyone Archers using it? What experiences have you had good and bad? If I enable it, can I still post with problems and questions to these forums or is it considered another distro and banned from discussion?

https://lists.archlinux.org/hyperkitty/ … BKUZSEXP4O has some info , but I don't think any arch devs are working on this.

The alhp repo is on the unoffical user repo list, so may be acceptable .

One thing I personally don't like is that they default to O3 where archlinux default is O2*

I think you should ask forum moderators directly about this.

* yes, some of my aur packages do use O3. Those are following upstream recommendation AND have been tested by me successfully .

I cannot comment on that specific repo, but on the more specific topic of CFLAGS: I have been running Openwrt on x86-64 for months now which I compile with CONFIG_KERNEL_CFLAGS="-march=znver3 -O3 -pipe" and with CONFIG_BUSYBOX_CONFIG_EXTRA_CFLAGS="-march=znver3 -O3 -pipe" which is their build system's equivalent of passing those options on to the kernel and to the packages. I have not seen any breakage of routing, snort, kernel stuff, samba4, nor containers. Can't comment on any real performance differences though

I'll raise the topic in the Mod discussion area, but my gut feeling is that this isn't supportable by this community.

There have been a few discussions in the past about officially supporting optimised builds, but I don't think there's any effort ongoing on that front.

That repo replaces a large amount of official packages and includes its own custom tools, which have lead to pacman segfaults amongst other issues. Suffice to say any issues arising with your install after using this repo should be directed to its author.

I tried it and it has been stable since I switched over. I am surprised more people haven't replied to say they are using it.

Does if offer much in the way of performance improvement? Have you benchmarked the difference at all?

Do you have a reference for the pacman segfault. I'd be amazed if it was caused by additional optimisation.

It was related to a faulty rewrite of repo-add used by the repository, not a recompilation of pacman with new flags:

I've been using it for a while, improves ram usage and idle CPU usage, it probably makes things faster but I haven't compared it to a normal system install. I've experienced no bugs except one, which was something with firefox that got fixed pretty quickly without me having to do anything.

Hi, I am considering adding v3 repos from ALHP, it seems that the project is well maintained and organised. A bit scary though, considering the amount of packages to upgrade. Any further feedback from users, who can state they see an impact on performance?
