I guess we never noticed and tried to build with this cross image. Fix
the toolchain prefix so we actually build 32 bit images.

The commit 4f9a8315e6 (gitlab-ci.d/crossbuilds: Drop the i386 system
emulation job) was a little too aggressive dropping testing for 32 bit
system builds. Partially revert but using the debian-i686 cross build
images this time as fedora has deprecated the 32 bit stuff.
As the SEV breakage gets in the way and its TCG issues we want to
catch I've added --disable-kvm to the build.

They don't need to be in the global trace-events file and can have a
local trace header. Also add address_space_map tracepoint for tracking

Really the problem here is the return values of fit_load_[kernel|fdt]() are a
little all over the place. However we don't want to somehow get
through not having set kernel_end and having it just be random unused
data.
The compiler complained on an --enable-gcov build:

Akihiko Odaki
From: Akihiko Odaki <akihiko.odaki@daynix.com>
Previously we are always specifying -u $(UID) to match the UID in the
container with one outside. This causes a problem with rootless Podman.
Rootless Podman remaps user IDs in the container to ones controllable
for the current user outside. The -u option instructs Podman to use
a specified UID in the container but does not affect the UID remapping.
Therefore, the UID in the container can be remapped to some other UID
outside the container. This can make the access to bind-mounted volumes
fail because the remapped UID mismatches with the owner of the
directories.
Replace -u $(UID) with --userns keep-id, which fixes the UID remapping.
This change is limited to Podman because Docker does not support
--userns keep-id.

This avoids a memcpy to the stack when compiled with clang.
Since we don't enable optimization, nor provide memcpy,
this results in an undefined symbol error at link time.

Define the variable to the compiler flag used, not "y".

complains if a 32-bit value is given. Explicitly specify register width

From: Akihiko Odaki <akihiko.odaki@daynix.com>
The test cases for "converting double-precision to single-precision"
emits float but the result variable was typed as uint32_t and corrupted
the printed values. Propertly type it as float.

This is perhaps a clang bug, but using the neon mnemonic is clearer.

For arm32 host and arm64 guest we get
.../main.c:851:32: error: result of comparison of constant 70368744177664 with expression of type 'unsigned long' is always false [-Werror,-Wtautological-constant-out-of-range-compare]

~~~~~~~~~~~~~~~~~~ ^ ~~~~~~~~~~~
We already disable -Wtype-limits here, for this exact comparison, but
that is not enough for clang. Disable -Wtautological-compare as well,
which is a superset. GCC ignores the unknown warning flag.

In fact any other accelerator would be pointless as the point is to
exercise the TCI accelerator anyway.

No, this is a Linux machine, and there's only TCG and KVM available for
Linux. No need to bother with the other accelerators here.

I noticed this is Linux. If for some reason the Xen libs get installed,
Xen accel will be enabled. Explicit would be:
--enable-tcg --enable-tcg-interpreter --disable-kvm --disable-xen
But I won't insist. Anyhow Alex sent his pull request.

Phil.

Oh, drat, I somehow only had the hvf and whpx accelerators in mind... You're
right, --disable-xen is certainly a good idea here, too:
https://gitlab.com/qemu-project/qemu/-/jobs/7281510036#L583
Mind to send a patch on top of the previous one?

While the match functionality is useful lets make the verbosity
optional while we are actually running.

We were repeating information which wasn't super clear. As we already
will have dumped the last failing PC just note the divergence and dump
the previous instruction log.

From: Gustavo Romero <gustavo.romero@linaro.org>
Move GdbCmdParseEntry and its associated types into a separate header
file to allow the use of GdbCmdParseEntry and other gdbstub command
functions outside of gdbstub.c.
Since GdbCmdParseEntry and get_param are now public, kdoc
GdbCmdParseEntry and rename get_param to gdb_get_cmd_param.
This commit also makes gdb_put_packet public since is used in gdbstub
command handling.

From: Gustavo Romero <gustavo.romero@linaro.org>
Currently, it's not possible to have stubs specific to a given target,
even though there are GDB features which are target-specific, like, for
instance, memory tagging.
This commit introduces gdb_extend_qsupported_features,
gdb_extend_query_table, and gdb_extend_set_table functions as interfaces
to extend the qSupported string, the query handler table, and the set
handler table, allowing target-specific stub implementations.

From: Gustavo Romero <gustavo.romero@linaro.org>
Factor out the code used for setting the MTE TCF0 field from the prctl
code into a convenient function. Other subsystems, like gdbstub, need to
set this field as well, so keep it as a separate function to avoid
duplication and ensure consistency in how this field is set across the
board.

From: Gustavo Romero <gustavo.romero@linaro.org>
This commit implements the stubs to handle the qIsAddressTagged,
qMemTag, and QMemTag GDB packets, allowing all GDB 'memory-tag'
subcommands to work with QEMU gdbstub on aarch64 user mode. It also
implements the get/set functions for the special GDB MTE register
'tag_ctl', used to control the MTE fault type at runtime.
