#ChimeraLinux

1 post1 participant1 post today

Suite du changement d'OS :
Je sais pas vous, mais moi je sens bien, chez moi. Je commence à me faire à Chimera Linux. Quand on est habitué à Debian et sa doc monolithique pour tous les outils de base, il faut juste se faire à l'idée de chercher la doc à différents endroits : Chimera, Artix, FreeBSD, etc. Et finalement, tout est bien plus simple, une fois l'adaptation passée.

(Remarque : j'ai un fond d'écran plus apaisé dans les autres espaces, trop de rouge ici)

Thanks to
@chimera_linux for putting together all the best tools from the floss world :meow_smile_happy: I was prepared to much harder work to get it work, giving that it is only in beta since December! #ChimeraLinux #chimeralinux

linkedlist.org/ is now hosted on #ChimeraLinux using a mini-CDN/Edge network I built. I have a servers in Australia, France, and USA with GeoDNS selecting which one to send you to.

Is this needlessly complicated for such a low-traffic website? Yes, but I wanted to try to make it faster for more people and here we are. I already had the AU server and the other two cost just over $US1/month, so it shouldn't send me broke… hopefully.

@osnews PSA from an owner of a custom Ampere Altra workstation: gpu/graphics choice is limited and affects OS choice! There is a reason System76 chose a NVidia gpu.

The Ampere Altra has a PCIe bug that causes problems with AMD gpus and the linux amdgpu driver, requiring an out-of-tree linux kernel patch that is sporadically maintained and unlikely to ever be upstreamed. (chimera-linux.org is the only distro that ships with this patch applied) The amdgpu drm driver maintainers have expressed no interest in working around this bug within the driver itself either.

Remember that this driver ends up in FreeBSD and OpenBSD too! Personally a Polaris generation gpu has worked with stock OpenBSD 7.6 kernel because the kernel handles device memory mapping differently than linux and doesn’t seem trigger the PCIe bug. With a newer Navi 2nd gen gpu, the bug interrupts firmware loading in stock OpenBSD. It can be worked around, but:

There is also an issue where Vega and newer gpus require cpu hardware floating point math in the kernel driver code which wasn’t supported on arm64 until drm in Linux 6.2. The most recent releases of FreeBSD and OpenBSD are either on an older drm than that, or haven’t ported the hardware floating point code within the kernel driver on arm64 yet. So even if you get the Navi firmware to load, you don’t get any farther than that (Display Core requires the fpu code).

Nvidia supports arm64 with their closed source driver and is unaffected the PCIe bug (or works around it, depending on what you read, but the code is secret so 🤷) but no BSD for you! They only have Linux arm64 drivers. The older cards supported by nouveau will also get you nowhere on BSD.

Also note that Nvidia DOES NOT ship an arm64 option rom GOP driver for EFI console graphics on any of their cards. Your motherboard/platform could provide an emulator in the UEFI firmware to use the x86-64 GOP driver (my Asrock motherboard doesn’t.) Polaris AMD gpus didn’t include arm64 GOP in the rom, but the 2nd gen Navi DOES. So you can get boot console on it but only working OS graphics on patched linux 🫠

There were a few defaults on Chimera Linux that commonly tripped up build tooling such as make being bmake, install being BSD install, and some other flags to tools like cp and ln. q66 has been on a quest lately to address these. Default make was switched to GNU make, install gained a GNU compatible mode, and other tools got compatibility arguments. The end result is far fewer patches required to build things. 🎉 For example:

Hi thought I'd better introduce myself. I'm Justine I'm a marine electronics engineer to trade which basically means I install / repair anything on a vessel from satellite internet and sat TV to autopilots, radars, VHFs and navigational equipment. Other than that I've been a #Linux user since around 2000 and even worked on the distro LRs Linux that basically compiled from scratch according to the users hardware and was LFS based. My current daily driver is #ChimeraLinux and my WM of choice is #RiverWm
I am currently migrating my #homelab from #Ubuntu to #FreeBSD.
