Booting Kernel on Amiga 3000

[Stephen Walsh]

Hi Guys,

I have "Debian GNU/Linux bookworm/sid" installed on both Qemu-user and
real hardware.

Amiga 3000
Warpengine ***@40Mhz
128Mb ram on warpengine
8Mb Fast ram on MB
2Mb Chip ram
X-surf Network card (Original)
Kickstart 3.2

Qemu is working with no issues.

Real hardware issue:

Booting kernel/inintrid 5.15.0-2 works and the machine boots all the
way.

Trying to boot with kernel/initrid 5.18.0-1 through to 5.18.0-4 results
in a grey screen and the machine doing nothing after amiboot loads in
the kernel. I have left it for 20 minutes with no change. Booting
5.15.0-2 starts showing the boot process after a couple of minutes.


amiboot -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false

When trying the newer kernel's, all I'm doing is replacing the
kernel/initrid with the newer versions.

Hi Stephen!

Might be a wise idea to cross-post this to the Linux/m68k kernel mailing list.

Also, kernel 5.19.6 is currently being built and should be available soonish.

Didn't know there was one.

I'll test that when it's released.

It's in the archives now. You can give it a try.

Uhm? How do you get the Warpengine with 128MB into an A3000? Usually there is not enough space on the Warpengine for 4x 32 MB SIMMs - or did you use 2x 64MB ones or 4x single sided 32 MB SIMM with two additional sockets?

https://people.debian.org/~cts/debian-m68k/woody/ refers to „debug=mem“ and „dmesg“ afterwards:

Append "debug=mem" to your boot line and run dmesg under AOS after a reboot. Please read the readme file.) and send the output to the appropriate list.

https://people.debian.org/~cts/debian-m68k/misc/dmesg.readme

Does this still work in newer kernels? Otherwise it would also be possible to use debug=ser if you have a serial (null modem) cable.

That's not relevant to this, but my A3000 isn't in a desktop case.

Ok, in an A3000 tower case you might use the Warpengine for the A4000 with vertical sockets and not tilted sockets as in the A3000 desktop version of the Warpengine.

So, here is the error and a possible solution: using a memfile might help.

http://amigadev.elowar.com/read/ADCD_2.1/Hardware_Manual_guide/node00D4.html and comparing with the memory lists shown in ShowConfig or SysInfo might help.

It seems that it tries to move the kernel around, but is unable to do so. Might be when the new kernel is loaded to Chip Mem and the other memory types like Fast Mem are not recognized or ignored. By default it only uses one memory chunk with highest priority, IIRC, but maybe Geert or so will correct me.
If things haven’t changed since my tries with BigRAM 256MB then you can only make use of a single memory chunk as RAM. More memory chunks like onboard memory can be used as ramdisk for swapping or so.

I've not done a memfile before so will need a pointer or two.

So, here is the error and a possible solution: using a memfile might help.

I've not done a memfile before so will need a pointer or two.

Quick pointer was to look it up in my blog about the BigRamPlus:

https://blog.windfluechter.net/2013/12/18/1677-debian-donation-m68k-arrived/

There you can find a memfile. Basically it is quite simple. First line should be ChipMem and in that example there are my 64 MB FastMem on the Warpengine. And next parameter to the starting address is the size in bytes.

Post by Stephen Walsh
The memory layout is like this. Seams to be all the time, booting into
3.1/ATK/SYSINFO
$08000000 - $0FFFFFFF 128Mb (WarpEngine)
$07800000 - $07FFFFFF 8Mb (Fast Ram)
$00004000 - $001FFFFF 2Mb (Chip Ram)
Z3 Warpengine $40000000 (16Mb)
Z2 X-Surf $00E90000 (64Kb)
Z2 Buddha IDE $00EA0000 (64Kb)

You’ll only need to include those address space that is actually RAM, not address space for firmware or IO stuff.

As there are only two regions of Fast RAM, and the second one should
not be used as it is slow motherboard RAM, I think a memfile won't
make a difference.

Why is there no initrd line here?

Note that your initial bad boot report (kernel 5.18.0-4 with corresponding
initrd) had:

initrd: 0f7f81c2 - 10000000

I.e. the initrd was located in the WarpEngine RAM.

What happens with the old kernel and the new initrd?

Hi Finn,

Here are three debugs..... mixing the kernel/intrid's...

What happens if you boot the 5.19 kernel/initrd pair with
"root=/dev/sda2" omitted from the kernel parameters?
It looks like the oops from the 5.18 build disappeared in the 5.19
build.
That makes me think that the 5.18 build would no longer oops when
used with the 5.19 initrd (?)

All boot attempts have ran with the following amiboot line (Changing
the kernel/initrd of course)

amiboot -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false debug=mem


amiboot is version 6, dated 11th may 2005.

Right. What I was saying was that you'd probably get better results if you
omitted root=/dev/sda2.

Or, if you want to keep using the same amiboot line, I suggest you try the
5.18 kernel with the 5.19 initrd. It won't boot correctly but it might
prevent the oops. (The theory was that the 5.18 initrd grew too big.)

omitted root=/dev/sda2.

Please disregard that. I realize now that the kernel is not aware of any
initrd at all, which is why it fails with "No filesystem could mount
root". It still looks like a bootloader issue to me.

It disappeared because the (too large?) initrd is no longer loaded...

Are you sure that is what you really used?

I missed this before, but all kernels that failed to mount their root
file systems, and printed no "initrd: <start> - <end>" lines, had the
"-r <initrd>" parameter in the kernel command line part:

Kernel command line: ignore_loglevel -r initrd.img-5.19.0-1-m68k
root=/dev/sda2 fb=false debug=mem BOOT_IMAGE=vmlinux-5.19.0-1-m68k

Hence Amiboot didn't provide the initrd...

Okay, so the first couple of logs Stephen sent used the correct command

Success:

Failure:
[ 0.000000] initrd: 0f7f81c2 - 10000000

Stephen, can you please confirm that (given the correct bootloader
command) 5.15 does indeed oops when presented with an initrd that's 8 MiB
(8388608 bytes) or larger? And conversely, 5.18 does not oops when
presented with an initrd that's smaller than 8 MiB?

I'll have to re-test when I get home tonight, as I've gone through many
attempts.

I was thinking this morning that perhaps amiboot/kernel/intrid is having
issues with the larger size.

Yes, that is what I've been using and works with 5.15

Screen shot of just before I started a new test. I boot the Amiga with
no startup-sequence and then run the script. (Saves typing).

I have seen it do that many times, but but boot correctly. I have also
seen amiboot get the system going and then either not find the hd, or
the nic or vis versa.

When I got the system installed last year it took many attempts due to
those issues, then someone posted the trick of copying the iso to the
swap space and the system finally installed.

Are you sure that is what you really used?

Yes, that is what I've been using and works with 5.15

I think that what Geert was getting at was the discrepancy between the
two test runs seen here:
https://lists.debian.org/debian-68k/2022/09/msg00015.html

The first has this:

[ 0.000000] Kernel command line: root=/dev/sda2 fb=false debug=mem BOOT_IMAGE=vmlinux-5.15.0-2-m68k
[ 0.000000] Unknown kernel command line parameters "fb=false BOOT_IMAGE=vmlinux-5.15.0-2-m68k", will be passed to user space.

Whereas the second has this:

[ 0.000000] Kernel command line: ignore_loglevel -r initrd.img-5.15.0-2-m68k root=/dev/sda2 fb=false debug=mem BOOT_IMAGE=vmlinux-5.18.0-4-m68k
[ 0.000000] Unknown kernel command line parameters "-r fb=false BOOT_IMAGE=vmlinux-5.18.0-4-m68k", will be passed to user space.

The presence of "-r filename" in the second log indicates that amiboot did
not act upon those arguments but passed them to the kernel instead.

When you run the tests I proposed, please use the first method again i.e.
omit "ignore_loglevel".

oh right, the "ignore_loglevel" is in the wrong location: it should be
located after the initrd.

In the screenshot you showed, "ignore_loglevel" was the last parameter,
which is fine.

Hi Guys.

As requested.

Finn I also tried kernel 5.19 with intrid 5.15..

Still only Kernel/Intrid 5.15-02 is the one that boots.

Hi Guys.
As requested.

Thanks for sending those results.

Post by Stephen Walsh
Finn I also tried kernel 5.19 with intrid 5.15..
Still only Kernel/Intrid 5.15-02 is the one that boots.

You mean, you tried kernel 5.15 with initrd 5.19? The question is, "did it
oops?". Having seen the results below, I suspect that it didn't oops,
despite the large initrd.

Post by Stephen Walsh
amiboot -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false debug=mem

OK.

Length is 0x7cd7c4 which is below 8 MiB. Moreover, this is a known-good
initrd. So the oops appears to be caused by a kernel change and not initrd
growth.

If you would like to try to narrow down the problem a little, there are
5.16 and 5.17 builds available here:

https://snapshot.debian.org/archive/debian-ports/20220403T020744Z/pool-m68k/main/l/linux/

I recommend extracting the vmlinux binary from the deb directly (using ar
and tar) rather than installing the deb.

Hi Finn,

You mean, you tried kernel 5.15 with initrd 5.19? The question is,
"did it oops?". Having seen the results below, I suspect that it
didn't oops, despite the large initrd.

You mean, you tried kernel 5.15 with initrd 5.19? The question is,
"did it oops?". Having seen the results below, I suspect that it
didn't oops, despite the large initrd.

ohh.. here's a successful boot with vmlinux-5.15.0-2-m68k

Here's a test of kernel 5.16, intrid 5.16. It exited to busybox saying
it couldn’t find /dev/sda2 (root fs)

That seems to be an unrelated issue. To pursue that one, I would
cross-compile a monolithic Amiga kernel from kernel.org source and use git
bisect to find the regression (assuming it's a regression). But not
everyone is comfortable building Linux from source and even if you were
the early crash would prevent you from debugging the scsi issue anyway. So
you need a way to boot 5.19 without oops. Can you achieve that by altering
the RAM configuration?

A monolithic Amiga kernel does not need an initrd, so it won't suffer
from the early crash.

[ 0.000000] initrd: 0f83283d - 10000000

Length is 0x7cd7c4 which is below 8 MiB. Moreover, this is a known-good
initrd. So the oops appears to be caused by a kernel change and not initrd
growth.

All these have the initrd in the second memory chunk - at least one of
the successful boots had the initrd in the first (8 MB) chunk).

I know nothing about the way amiboot works, and how the RAM chunk to
copy the initrd image to is selected. Just speculating: maybe amiboot
plus initrd size must be below 8 MB for the first chunk to get used?

But that's a little academic. I really wonder what makes the initrd at
the end of the second RAM chunk fault. But e.g. the range

0f83283d - 10000000

extends one byte beyond what's mapped

node 0: [mem 0x0000000008000000-0x000000000fffffff]

and the fault occurs at faddr=0ffffff4, at which point the processor
probably pre-fetched out to 10000000.

I need to dig out the 68040 manual to check what frame format 7 means...

Cheers,

Michael

Same here. This is not a bug I can resolve. It's a bug for someone who
knows Amiga hardware and amiboot algorithms.

Interesting. That's the failure case. But in the success case, that "one
byte" was always the first byte in the "node 0" mapping. Maybe you're onto
something.

Length is 0x7cd7c4 which is below 8 MiB. Moreover, this is a known-good
initrd. So the oops appears to be caused by a kernel change and not initrd
growth.

All these have the initrd in the second memory chunk - at least one of
the successful boots had the initrd in the first (8 MB) chunk).
I know nothing about the way amiboot works, and how the RAM chunk to
copy the initrd image to is selected. Just speculating: maybe amiboot
plus initrd size must be below 8 MB for the first chunk to get used?

m68kboot/common/amiga/linuxboot.c

bi.ramdisk.addr = (u_long)start_mem+mem_size-rd_size;

However, that's not where it is loaded initially:

memreq = kernel_size+bi_size+rd_size;
memptr = (char *)AllocMem(memreq, MEMF_FAST | MEMF_PUBLIC | MEMF_CLEAR);

I expect the allocated memory to be from the largest (second)
block of memory.

Later, everything is copied to the first memory block.
But from a quick glance, I see no check to verify the first
block is sufficiently large.

I think we really need to see the output of "amiboot -d",
for both the good and the bad cases.

But that's a little academic. I really wonder what makes the initrd at
the end of the second RAM chunk fault. But e.g. the range
0f83283d - 10000000
extends one byte beyond what's mapped
node 0: [mem 0x0000000008000000-0x000000000fffffff]

That's because the first printed range is initrd_start, initrd_end,
while the second is (u64)start_pfn << PAGE_SHIFT,
((u64)end_pfn << PAGE_SHIFT) - 1).

Post by Michael Schmitz
and the fault occurs at faddr=0ffffff4, at which point the processor
probably pre-fetched out to 10000000.

Or perhaps memcmp() (that's __builtin_memcmp()?) loads 4 words
at once?

Hi Geert.

Post by Geert Uytterhoeven
I think we really need to see the output of "amiboot -d",
for both the good and the bad cases.

I had amiboot like so:

amiboot -d -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false

Didn't see anything different, in the output except for this at the
start of the process:

Hi Stephen,

I think we really need to see the output of "amiboot -d",
for both the good and the bad cases.

amiboot -d -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false
Didn't see anything different, in the output except for this at the
https://amiga.vk3heg.net/wp-content/uploads/2022/09/PXL_20220909_120251490.MP_-scaled.jpg

Which says "ramdisk dest is 0x0f83283d"...

... which does not match 0783283d?

Interestingly, this is the working case.

While the non-working case in your next email has
"ramdisk dest is 0x0f7f6794" and a matching
"initrd: 0f7f6794 - 10000000".

/me confused even more...

Length is 0x7cd7c4 which is below 8 MiB. Moreover, this is a known-good
initrd. So the oops appears to be caused by a kernel change and not initrd
growth.

All these have the initrd in the second memory chunk - at least one of
the successful boots had the initrd in the first (8 MB) chunk).

Just spotted another difference - in the success case, the initrd log
message is printed after the initmem setup log message.

Maybe add initcall_debug to the kernel options so we see what happens in
which order in succes and fault cases?

Post by Finn Thain

Post by Michael Schmitz
I know nothing about the way amiboot works, and how the RAM chunk to
copy the initrd image to is selected. Just speculating: maybe amiboot
plus initrd size must be below 8 MB for the first chunk to get used?

m68kboot/common/amiga/linuxboot.c
bi.ramdisk.addr = (u_long)start_mem+mem_size-rd_size;

That's after figuring out which RAM segment the kernel will get loaded
to. If I understand you right, that is always the first memory block. In
all cases, this is the 0x8000000 one (hence the message about chunk
0x7800000 getting ignored by mem setup).

But the initrd does not always get loaded at the end of the kernel RAM
segment - in fact, in all cases where it's instead loaded to the later
ignored segment, the kernel boots fine.

Post by Finn Thain
memreq = kernel_size+bi_size+rd_size;
memptr = (char *)AllocMem(memreq, MEMF_FAST | MEMF_PUBLIC | MEMF_CLEAR);
I expect the allocated memory to be from the largest (second)
block of memory.
Later, everything is copied to the first memory block.
But from a quick glance, I see no check to verify the first
block is sufficiently large.
I think we really need to see the output of "amiboot -d",
for both the good and the bad cases.

Post by Michael Schmitz
But that's a little academic. I really wonder what makes the initrd at
the end of the second RAM chunk fault. But e.g. the range
0f83283d - 10000000
extends one byte beyond what's mapped
node 0: [mem 0x0000000008000000-0x000000000fffffff]

That's because the first printed range is initrd_start, initrd_end,
while the second is (u64)start_pfn << PAGE_SHIFT,
((u64)end_pfn << PAGE_SHIFT) - 1).

And in the success case, initrd_end does just serendipitously happen to
be mapped (first byte of the kernel RAM segment), while in the problem
case it doesn't (beyond end of kernel RAM segment).

How is initrd_end calculate? It's just initrd_start + initrd_size, which
is just fine because the calculation of the bootconfig address from
initrd_end is correct, and initrd_end should never be accessed.

Post by Finn Thain

Post by Michael Schmitz
and the fault occurs at faddr=0ffffff4, at which point the processor
probably pre-fetched out to 10000000.

Or perhaps memcmp() (that's __builtin_memcmp()?) loads 4 words
at once?

It's lib/string.c:memcmp() for me. That does load (unsigned long) for as
long as there's still more than sizeof(unsigned long), then compares bytes.

Might depend on the GCC version?

Changing amiboot to leave some space before the end of RAM is probably
quite hard, but moving the loaded initrd down by a few bytes early on in
the boot (in setup_arch()??) might be a simple way to test the hypothesis.

Cheers,

Michael

amiboot -k vmlinux-5.15.0-2-m68k -r initrd.img-5.15.0-2-m68k
root=/dev/sda2 fb=false debug=mem

Are you sure that is what you really used?

Yes, that is what I've been using and works with 5.15
Screen shot of just before I started a new test. I boot the Amiga with
no startup-sequence and then run the script. (Saves typing).
https://amiga.vk3heg.net/wp-content/uploads/2022/09/PXL_20220907_121140311-scaled.jpg

That indeed looks good.
Does Amiboot print that it actually loads the ramdisk?

Post by Stephen Walsh

Post by Geert Uytterhoeven
I missed this before, but all kernels that failed to mount their root
file systems, and printed no "initrd: <start> - <end>" lines, had the
Kernel command line: ignore_loglevel -r initrd.img-5.19.0-1-m68k
root=/dev/sda2 fb=false debug=mem BOOT_IMAGE=vmlinux-5.19.0-1-m68k

I have seen it do that many times, but but boot correctly. I have also
seen amiboot get the system going and then either not find the hd, or
the nic or vis versa.

That's really strange. Amiboot should only pass the last unrecognized
parts of the parameters as the kernel command line.
Any chance there is not a real space, but a non-breaking space
(SHIFT + SPACE, 0xa0) after the "-r", confusing the parser?

Can you try running Amiboot with "-d"? That will print more info about
the used addresses, and will give you more time to read its output,
by waiting for a keypress before launching Linux.

Thanks!

Here are three debugs..... mixing the kernel/intrid's...

What happens if you boot the 5.19 kernel/initrd pair with "root=/dev/sda2"
omitted from the kernel parameters?

It looks like the oops from the 5.18 build disappeared in the 5.19 build.

That makes me think that the 5.18 build would no longer oops when used
with the 5.19 initrd (?)

Expanding a little on what Andreas said above: Linux/m68k doesn't produce
precise backtraces. What gets printed is any value found on the stack that
could possibly be interpreted as an instruction pointer i.e. any address
within a kernel code segment.

Stack corruption?

No, i's not an oops, it's normal behaviour:

[ 3.110000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

This expected, and it is not the crash that was originally reported.

Regarding the oops that was originally reported, the kernel already told
us why it crashed:

[ 0.000000] Ignoring memory chunk at 0x7800000:0x800000 before the first chunk
[ 0.000000] Fix your bootloader or use a memfile to make use of this area!

Hence Geert's questions aimed at figuring out what's going on with the
bootloader.

Post by Laurent Vivier
0x8001 looks like
uapi/asm/bootinfo-amiga.h:#define BI_AMIGA_AUTOCON 0x8001 /* AutoConfig device */

By the time the kernel gets to mounting the rootfs, the stack frame
generated by amiga_parse_bootinfo() has been clobbered many times over.

Maybe. It would be nice if the oops message offered us the fault address
like it used to, instead of "Unable to handle kernel access at virtual
address (ptrval)". This is a regression, IMO, that could be easy or hard
to fix, depending on reviewers' notion of "security"...

Which matches

data = (char *)initrd_end - BOOTCONFIG_MAGIC_LEN;

in init/main.c:get_boot_config_from_initrd(), the function identified
by Finn before.

So if the initrd is stored at the end of motherboard RAM:

initrd: 0783283d - 08000000

The code

memcmp(data, BOOTCONFIG_MAGIC, BOOTCONFIG_MAGIC_LEN)

works. When the initrd is stored at the end of WarpEngine RAM:

initrd: 0f7f81c2 - 10000000

it crashes, probably because it is not mapped.

According to

Initmem setup node 0 [mem 0x000000000a000000-0x000000000fffffff]

the memory should be mapped, shouldn't it?

So we see an ATC fault when reading from an address that's mapped but no
fault when the initrd is located in "unused" memory. I find that
surprising. Yet the fault address is initrd_end - BOOTCONFIG_MAGIC_LEN.
Anyway, it appears Geert is right and I was wrong about the memory chunk
at 0x7800000:0x800000 being the cause of the fault. But it does look like
the use of that chunk may have prevented the fault in the success case.

Amiga 3000
128Mb ram on warpengine

Uhm? How do you get the Warpengine with 128MB into an A3000? Usually
there is not enough space on the Warpengine for 4x 32 MB SIMMs - or
did you use 2x 64MB ones or 4x single sided 32 MB SIMM with two
additional sockets?

That's not relevant to this, but my A3000 isn't in a desktop case.

Still, it might help to narrow down the bug if you also test a RAM
configuration that others have had success with -- if possible.

When trying the newer kernel's, all I'm doing is replacing the
kernel/initrid with the newer versions.

Append "debug=mem" to your boot line and run dmesg under AOS after a
reboot. Please read the readme file.) and send the output to the
appropriate list.

This is the debug output.

[ 0.000000] Initmem setup node 0 [mem 0x000000000a000000-0x000000000fffffff]

That looks like the point where you'd normally see output from,

pr_info("Built %u zonelists, mobility grouping %s. Total pages: %ld\n",
nr_online_nodes,
page_group_by_mobility_disabled ? "off" : "on",
vm_total_pages);

but the address of this format string is not in the oops message. (It
might help to add "ignore_loglevel" to the kernel parameters.)

Anyway, 0040af3d and 0040af41 can be seen in the oops messages, which can
be found in "objdump -s" output:

40af30 6f707469 6f6e7300 01352573 0023424f options..5%s.#BO

40af70 6e697472 64207369 7a652025 6c640a00 nitrd size %ld..

I can't see how setup_boot_config() could crash before linux_banner got
printed... but it does do this,

if (!memcmp(data, BOOTCONFIG_MAGIC, BOOTCONFIG_MAGIC_LEN))
goto found;

which seems to fit the backtrace.

What happens if you boot the known-good initrd (v5.15) with the crashy
vmlinux binary (v5.18)?

The combination won't boot normally but should fail normally (wrong
modules) and not fail with an oops.

What happens if you boot the known-good initrd (v5.15) with the
crashy vmlinux binary (v5.18)?
The combination won't boot normally but should fail normally (wrong
modules) and not fail with an oops.

It still crashes, but I can see the process.

OK. I assume that it was the initrd change that prevented the oops and not
the addition of ignore_loglevel.

Your results suggest to me that the problem was triggered by the growth of
the initrd between v5.15 and v5.18.

My guess is that the bootloader made use of the 8 MB memory chunk which
was later discarded by the kernel.

[ 0.000000] Ignoring memory chunk at 0x7800000:0x800000 before the first chunk

This may actually be a bootloader bug, i.e. memory chunks not in the
correct sequence (?).

Anyway, I agree with Ingo, this problem has to do with memory layout
and/or bootloader behaviour and the way to avoid it is probably a memfile.

As I have no experience with booting Linux on Amigas I can't be of much
more help unfortunately. So I'll stop guessing and leave this to the Amiga
experts.
