Dear maintainer(s),

It seems that the last blocker to fix the migration of edk2 (bug
1119236) now is an autopkgtest regression on s390x.

With a (not so) recent upload of edk2 the autopkgtest of edk2 fails in
testing when that autopkgtest is run with the binary packages of edk2
from unstable. It passes when run with only packages from testing. In
tabular form:

                        pass            fail
edk2                   from testing    2025.11-5
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration to testing [1]. Can
you please investigate the situation and fix it?

Hi, all

I can reproduce this test failure locally. I believe the reason is that the
implementation of the pvscsi device in qemu is broken when the endianness of
the guest and the host differs.

It can be easily seen in the driver code of pvscsi that the command data is
sent through a register in units of 32bits in the native endianness. In the
qemu emulated device code, however, although qemu has done the endianness
translation of the registers, the command data is received as a data stream
and filled into a buffer. When a field of a command data struct is 64bits long,
the upper 32 bits and the lower 32 bits will be flipped resulting the
mis-interpretation of the command data.

As a suggestion, I think pvscsi should be disabled on cross-endianness qemu
builds before the implementation is fixed in upstream and the test of
OVMF.legacy.fd on amd64 virtual machines on s390x should be disabled.

Cheers,

Miao Wang

Oh wow.

Can you post this to the qemu mailing list please?
That sounds like a big issue.

Hi, mjt

I have posted my patch fixing pvscsi emulation on big-endian hosts to the qemu-devel
mailing list [1]. However, I have not received any response till now.

Cheers,
