Debian Linux under FS-UAE

Hi,

I prepared Debian 8 image for FS-UAE. It's available here:

https://drive.google.com/folderview?...GM&usp=sharing

Please read the Info doc for details.

Enjoy!

Thanks will give it a go

Somewhat unsettling to see Linux in an emulated Amiga in FS-UAE use a newer kernel than I use on my main computer

Nice one! Thanks

In Info you say...

Q: Is networking working

A: Yes, with qemuuae plugin.

But in https://fs-uae.net/download#plugins it says that qemu-uae is Plugin for PPC emulation. Something doesn't add up?

How did you make that? Cross-compiled from linux or something?

The documentation isn't completely accurate. It is also used for slirp network support. I'll update the information on the download page.

Hm, for some reason it doesn't work here: The kernel can't find the root partition.
Using Linux, fs-uae-devel from git and Linux-A1200.fs-uae config

sha1sum TEST.hdf*
37a8299e5fff8a07a3237ebfb92ee014d9643496  TEST.hdf
6f6af4f5e3d480333993dc40e0808704ce949565  TEST.hdf.xz

Edit: Boots fine with fs-uae 2.6.2 after changing amiga_model to A1200/020 and WinUAE 3.1.0. Fails to boot (same error) with WinUAE 3.3.0 Public Beta 10 and 3.2.2.
So perhaps a (Win)UAE bug or wrong config (but I used the same one...).

Most likely a qemu or Linux kernel bug where support for IDE controller in Amiga is broken. If you pause the booting process of the kernel you should see something along

"ide0: Unknown number of cylinders. ide0 ignored"

I fixed it some time ago by using Amiga3000 with SCSI, which seems to work better. Here's the config

[fs-uae]
amiga_model = A3000
accelerator = cyberstorm-ppc
accelerator_memory = 131072
accelerator_rom = /home/jagger/Documents/FS-UAE/Kickstarts/cyberstormppc.rom
cpu = 68060
accuracy = 0
video_sync = off
uae_cpu_speed = max
fpu_strict = true
bsdsocket_emu = false
floppy_drive_count = 0
chipset_compatible = A3000
hard_drive_0 = DEBIAN.hdf
hard_drive_0_controller = scsi0
hard_drive_0_label = DEBIAN
kickstart_file = /home/jagger/Documents/FS-UAE/Kickstarts/a3000.rom
chip_memory = 2048
uae_z3mem_size = 1024
uae_z3mem_start = 0x80000000
uae_sana2 = true
uae_a2065 = slirp
uae_slirp_implementation = qemu
floppy_drive_count = 0

but for it to work, you need to make 2 changes

a). change <amiga_affs_partition>/s/startup-sequence hda2 -> sda2
b). change <linux_partition>/etc/fstab hda2 -> sda2

It's possible to do it on local Linux, but you need to do some magic with losetup and mount.

losetup -P /dev/loop0 TEST.hdf
mount -t affs /dev/loop0p1 /mnt/affs
mount -t ext4 /dev/loop0p2 /mnt/ext4


after modification perform the following:
umount /mnt/affs
umount /mnt/ext4
losetup -d /dev/loop0

Also, you'd need A3000 rom, because the one delivered with FS-USE doesn't seem to support boot-from-scsi, and Cyberstorm ROM, w/o which it doesn't boot well.

Kernel is cross-compiled. The root image is debootstrap'd with different architecture under chroot. Well.. it's actually a bit more complicated (debootstrap doesn't set-up all packages correctly, so I re-installed individual packages after boot).

No joy on FS-UAE 2.4.1 either as A1200 or A1200/20

Upgraded to FS-UAE 2.6.2 and i'm up and running as A1200/20.

I think, it's a little strange that it works with earlier Win-/FS-UAE versions and with more recent ones it doesn't.

Anyway... It works with A3000+cs-ppc+scsi. Loop-mounting the .hdf wasn't possible with my kernel because it has no support for Amiga partition type. Most distros disable it, because nobody needs it nowadays (except us of course ). I used Amiga Workbench to change the startup-sequence and the emergency shell for fstab.

It's really nice to see a recent kernel running on m68k with all the modern stuff like systemd. I wonder how it would perform on real hardware...

Wierd, I'm using FS-UAE 2.6.2 and the 1200/020 combo gives me a guru every time. Is this config missing anything (I tried both 020 options)?

[fs-uae]
amiga_model = A1200
chip_memory = 2048
cpu = 68EC020
fast_memory = 8192
hard_drive_0 = /home/TLF/Downloads/linux on amiga/TEST.hdf
kickstart_file = Amiga kick31.rom
slow_memory = 1024

[FrodeSolheim]

Don't you need an MMU for Linux? Try amiga_model = A4000 with cpu = 68040 or cpu = 68060.

[TenLeftFingers]

I get "Kernel Panic - not syncing" "out of memory and no killable processes" with these settings:

[fs-uae]
amiga_model = A4000
chip_memory = 2048
cpu = 68040
fast_memory = 8192
hard_drive_0 = /home/jarlath/Downloads/linux on amiga/TEST.hdf
kickstart_file = Amiga kick31.rom
motherboard_ram = 65536
slow_memory = 1024
zorro_iii_memory = 1048576

But as Jagger says above, it could be a linux kernel 4.6.0 bug?
