Atari AHDI partition support not enabled in Zen kernel... how to add it?

Issues & Assistance Unsupported Software (AUR & Other)
1

Many years ago I used various flavors of Ubuntu and they all had built-in support for mounting Atari disk partitions, which was extremely convenient for transferring files between Ataris and Linux PCs using SD cards. Ever since I left Ubuntu I haven’t been able to do this. It seems the ability is still in the kernel source but it’s not enabled in most distros. I can see the source files in the Zen repo, but I don’t know how to enable them to recompile them into the kernel. From what I’ve been able to gather, it doesn’t seem to be a kernel module. Here is what I found looking at the source repo:

There’s so little information on this, I don’t really know where to look for help on how to do this… but I’d really like the ability to just pop Atari formatted SD cards into my computer and mount them with Dolphin like I used to.

Any assistance would be appreciated.

I checked /proc/config.gz on my -zen and indeed
1050 │ # CONFIG_ATARI_PARTITION is not set
so you’d have to recompile it with that config option or hope some other kernel variant still has it compiled in.

I was going through this forum with your same question https://atari-forum.com/viewtopic.php?t=18697

And came across this. Check it out.

I found that too, but that program is QT3. I didn’t feel like trying to get QT3 working on my system… probably better to try to port it to QT5 or 6, but I don’t have time to learn how to do that.

Really sucks, with how often there are kernel updates. I don’t know how much trouble it is to recompile the kernel but it doesn’t sound fun.

6

Hmm in that case there are several YouTube videos on how to compile your own kernel just to inform you it’s a long process. If you like documentation,

https://wiki.archlinux.org/title/kernel#Compilation

Btw, is there a specific reason for not just using qt3? I mean it’s there in AUR.

Thanks. Yeah it doesn’t look fun.

Well, the truth is qt3 was just the first roadblock and I was expecting a lot more. I haven’t had the best luck compiling Linux programs that old, there’s usually many problems with libraries. On top of that, I’d rather have built-in OS support for the filesystem so I can just use Dolphin or the terminal to move files around.

For now I have an alternate solution to transfer files using the Hatari emulator with disk images that I am dd’ing back and forth to sd cards. Quite convoluted but it works.

Thanks to some advice over on atari-forum.com, I have found a better solution using the Hatari emulator. Instead of dding a disk image on and off the SD card, the much nicer solution is to use a udev rule to give yourself full access to the card reader device and then use that device (in my case /dev/sdk) as the file in the Hatari config for your hard drive image.

For my system my udev rule looks like this:

SUBSYSTEM=="block", ATTRS{idProduct}=="0749", ATTRS{serial}=="000000001539", ACTION=="add", RUN+="/bin/setfacl
-m u:serqetry:rw- /dev/$name"

This is probably the easiest solution. Just pop the card in, start Hatari and the SD card will be mounted (assuming you have everything set up properly with a hard disk driver installed on the emulated Atari), copy files back and forth all you want and the card will still work properly in a real Atari.
