I can't reproduce this, including with your kernel binary, which
suggests that this an issue with your FVP usage and firmware.

How are you invoking the FVP, what firmware are you using and how is it
configured?

This is an undefined instruction, my first thought there would be that
you have some feature enabled for the kernel which requires enablement
at EL3 but your EL3 firmware is not configured to enable it.

This is where the undef came from.

FWIW, I just grabbed your Image from:
https://builds.tuxbuild.com/2BnQMpJj3kDTJXoCwd2pY5gW9CN/
... and it boots perfectly fine under:
* An FVP Base RevC model using the latest boot-wrapper
* a QEMU KVM VM on a ThunderX2 host.
* a QEMU TCG VM on a ThunderX2 host (with -cpu max).
What firmware are you using in your FVP? How are you loading the kernel?

This looks bad. IIUC that "actual" line tells us that the instruction we wanted
to modify consisted of zeroes, and was not a NOP as it should have been.
So perhaps the kernel has not been fully loaded into memory, or has been
corrupted somehow after loading. That could explain the subsequent failure, too.

We should really improve this WARN to something that tells us about the actual
failing instruction.

Also with TF-A and u-boot (both some random recentish tip of tree
whenever I last built them).

FWIW, I've put together a series to improve the reporting here:

Thanks for investigating the reported issue and providing details.
We will do the needful to update / configure EL3 firmware.

Here I am providing the available data.
Let me know what I am missing here, so that I will update my setup.

... and this command line (modulo paths, and providing my own bogus rootfs) ...
... and this boots as far as loading userspace on a couple of models I've tried
it on (though the latest internal model I have doesn't like the PCI options).
I note that your log has:
| Hit any key to stop autoboot: 1 0
| smh_open: ERROR fd -1 for file 'boot.img'
| smh_open: ERROR fd -1 for file 'Image'
| smh_open: ERROR fd -1 for file 'devtree.dtb'
| smh_open: ERROR fd -1 for file 'ramdisk.img'
... whereas mine has:
| Hit any key to stop autoboot: 0
| smh_open: ERROR fd -1 for file 'boot.img'
| loaded file Image from 80080000 to 82F299FF, 02EA9A00 bytes
| smh_open: ERROR fd -1 for file 'devtree.dtb'
| smh_open: ERROR fd -1 for file 'ramdisk.img'
| fdt - flattened device tree utility commands
... and I wonder if that has something to do with it, given it appears that
your Image is corrupted somehow.
Full log below.
Thanks,
Mark.

11.18 was released since (not that it should make any difference to this
issue).

Where did you get the TF-A and u-boot from - what versions are they and
how are they configured and built? Especially TF-A, u-boot isn't likely
to cause any issues here since it isn't responsible for initialising the
higher ELs.
That said I do seem to be able to boot with those images on my system -
it looks like a debug build of TF-A 2.5 and a modified version of u-boot
2021.04. There's newer releases of both, especially with TF-A I'd
recommend keeping up with new releases though it doesn't *immediately*
look like your issue here.

You don't seem to have
-C cluster0.mpidr_layout=1
-C cluster1.mpidr_layout=1
though I would expect that the system wouldn't get as far as it was
without that, it doesn't seem to when I try testing here - it dies
running TF-A.
You might also want to turn on a few more options
-C cluster0.has_fgt=1
-C cluster1.has_fgt=1
-C cluster0.memory_tagging_support_level=3
-C cluster1.memory_tagging_support_level=3
-C bp.dram_metadata.is_enabled=1
to turn on fine grained traps and MTE, plus at least the newer model has
more base architecture extensions, though these shouldn't be the issue
here. They don't seem to be (and shouldn't be) relevant here though.
FGT is an EL2 feature so it'd die earlier.

Naresh's command line is putting Image directly into RAM with
--data cluster0.cpu0=/tuxrun-r4_1075p-lava-1/Image@0x80080000

Likewise in mine:
--data cluster0.cpu0=/mnt/data/models/fvp/naresh/Image@0x80080000
... as I'm using the same command line, just with paths altered.

... and I've just reproduced the issue by running the script from a different
directory, since apprarently the semihosting interface just grabs the file from
the current directory.
I'm pretty sure this means that *something* is clobbering the Image early on
during boot, and the semihisting loading happens to refresh it.
Thanks,
Mark.

I had a go with my own kernel built from my arm64/traps/rework branch:
https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/log/?h=arm64/traps/rework
... and Naresh's config:
https://builds.tuxbuild.com/2BnQMpJj3kDTJXoCwd2pY5gW9CN/config
When *only* using the initial loading into memory, that blows up in stackdepot
and with a subsequent bogus pointer dereference (full log below), and when
loaded via semihosting that just works. Note that my kernel is based on the
arm64 for-next/core branch, which itself is based on v5.19-rc3.
My failing kernel Image is ~47M, as is Naresh's original Image. When using
smaller Images (as large as 43M so far), I don't see any issues.
I also note that if I enable KASAN_OUTLINE, the kernel is so big that it
clobbers the DTB, and cannot be booted. So this looks liek a problem with tha
arbitrary placement / limits chosen for U-Boot being too small, and this is not
a kernel bug.
Naresh, please can you fix your boot flow before reporting any further issues?
This sort of corruption will manifest in a number of ways, and we need to rule
that out for any other bug reports.
Thanks,
Mark.

Now I have understood the reason.

Yes.

Any further reports I will do needful initial investigation.

If you don't *need* to use u-boot for any reason then it might be worth
looking into using EDK2 instead, it will dynamically place loaded images
so you don't need to worry about size issues unless you actually run out
of memory which is a whole other problem.
