This series makes the necessary changes to allow the use of
--disable-tcg for arm.
For the v2 I have taken a more strict approach to avoid introducing
changes in behavior, specially regarding the cpregs hash table.
changes:
patch 5:
Move all cpregs related code from helper.c into cpregs.c;
patches 6 & 7:
These are ARMCPRegInfo and accessors that are currently in helper
files. I moved them into cpregs.c, otherwise we can't move the
helpers into tcg/
patch 11:
Richard suggested we handle the tcg_enable check in a header, but I
noticed that are many more instances of arm_rebuild_hflags being
called from code that is tcg-only, so I'm not sure if we want to
have the added overhead in all calls. I have extracted all of the
new tcg_enable() calls so we can judge if it's worth it.
dropped the previous patch 11:
[RFC PATCH 11/27] target/arm: only perform TCG cpu and machine inits if TCG enabled
This patch had a mistake when we moved
register_cp_regs_for_features() under tcg_enabled(). That caused the
cp_regs hash table to be empty and no registers being written in
write_cpustate_to_list().
v1:
https://lore.kernel.org/r/20230104215835.24692-1-farosas@suse.de
I have included the other two already reviewed series to facilitate
the merge. Patch 12 is the first from this series proper.
I could use some help with the last two patches which deal with the
fact that ptw.c needs CPUTLBEntryFull and probe_access_full which are
_currently_ only compiled with CONFIG_TCG=y.
The 3 cpregs patches were split from the larger commit[1] from the
original series. We're still left with one huge patch, but it is only
code movement, it can be checked with:
diff -u <(sed -n 's/^-//p' patch) <(sed -n 's/^\+//p' patch)
1- [RFC v14 14/80] target/arm: split cpregs from tcg/helper.c
https://lore.kernel.org/r/20210416162824.25131-15-cfontana@suse.de
Claudio Fontana (8):
target/arm: rename handle_semihosting to tcg_handle_semihosting
target/arm: wrap psci call with tcg_enabled
target/arm: wrap call to aarch64_sve_change_el in tcg_enabled()
target/arm: move helpers to tcg/
target/arm: Move psci.c into the tcg directory
tests: do not run test-hmp on all machines for ARM KVM-only
tests: do not run qom-test on all machines for ARM KVM-only
tests: device-introspect-test: cope with ARM TCG-only devices
Fabiano Rosas (11):
target/arm: Move PC alignment check
target/arm: Move cpregs code into cpregs.c
target/arm: Move define_debug_regs() to cpregs.c
target/arm: Move helper_set_pstate_* into cpregs.c
target/arm: move translate modules to tcg/
target/arm: Wrap arm_rebuild_hflags calls with tcg_enabled
target/arm: Move hflags code into the tcg directory
tests/tcg: Do not build/run TCG tests if TCG is disabled
target/arm: Move regime_using_lpae_format into internal.h
cpu-defs.h: Expose CPUTLBEntryFull to non-TCG code
target/arm: don't access TCG code when debugging with KVM

Move this earlier to make the next patch diff cleaner. While here
update the comment slightly to not give the impression that the

The debug_helper.c file will move into a tcg-specific directory, so
take the cpregs code out of it. That code needs to be present in KVM
builds as well.

still have non-tcg code to be removed from them:

This is in preparation to moving the hflags code into its own file
under the tcg/ directory.
Signed-off-by: Fabiano Rosas <farosas@suse.de>

I extracted these into a separate patch so we can discuss. If I move
the tcg_enabled check to a header that would add overhead for all the
calls where we know for sure that the code is running with TCG. And I
don't think we want a new arm_rebuild_hflags_foo to be used for common
code.

Skip the test_device_intro_concrete for now for ARM KVM-only build,
as on ARM we currently build devices for ARM that are not
compatible with a KVM-only build.
We can remove this workaround when we fix this in KConfig etc,
and we only list and build machines that are compatible with KVM
for KVM-only builds.
Alternative implementation provided by Alex.

The tests under tests/tcg depend on the TCG accelerator. Do not build
them if --disable-tcg was given in the configure line.
Test against CONFIG_TCG='' instead of CONFIG_TCG=y to account for
CONFIG_TCG=m.
sample output:
$ make check-tcg
GIT ui/keycodemapdb meson dtc
SKIPPED x86_64-softmmu guest-tests because TCG is disabled in this build

This struct has no dependencies on TCG code and it is being used in
target/arm/ptw.c to simplify the passing around of page table walk
results. Those routines can be reached by KVM code via the gdbstub
breakpoint code, so take the structure out of CONFIG_TCG to make it
visible when building with --disable-tcg.

When TCG is disabled this part of the code should not be reachable, so
wrap it with an ifdef for now.
This allows us to start using CONFIG_TCG=n (--disable-tcg in the
configure line).

Hmm. I would have hoped these could stay tcg-only, somehow.
I wonder if it warrants being an ARM_CP_SPECIAL_MASK value instead of svcr_write.

Why don't you fix it immediately? ... it shouldn't be too hard to add some
"depends on TCG" statements to the machine entries in hw/arm/Kconfig, should it?
Anyway, if that's not possible (yet), I suggest to add your hack to
qtest_cb_for_every_machine() instead, so you could change this in one
central place instead of adding a hack to each and every test that uses this
function.

My idea was to have in this series the minimum to unbreak the
--disable-tcg build and later bring the rest of the changes
incrementally.
(plus the cpregs code movement which conflicts with everything, so I'd
rather merge it sooner)

I havent't looked into it yet. If it turns out to be simple I can do it
now.

This test is basically checking "all the machines should
work". That's an important invariant to maintain, so
I don't think we should just skip it for Arm targets.

In general, what characterizes as "special" for a register to use
ARM_CP_SPECIAL_MASK?
And specifically for svcr_write, it seems to me that
helper_set_pstate_{sm,za} and arm_reset_sve_state are straight-forward
enough that they could (if it made sense) be used by non-tcg code
(except they eventually call vfp_set_fpscr that still needs to be
split).

But what does "all machines" mean in a no-TCG build? The original intent
of the patch was that only 'virt' should be present and therefore the
only one tested.

It means that the register has special-case handling code
in the translate.c/translate-a64.c TCG codegen functions.
Non-special registers can be handled all in the same way
(load a constant, read a field from the CPU state struct,
or call a read/write function); the special cases directly
emit code to handle whatever they are doing. See the switch
commented "Handle special cases first" in target/arm/translate-a64.c
function handle_sys().

It means "every machine the user can create". If the
machine can't run then either we shouldn't compile it
in, or else we should be compiling in enough extra stuff
to allow it to work.

To answer my own question, ARM_CP_SPECIAL_MASK forces NO_RAW, which is not what we want
for migration.
I'll think of something better here though.

Is this it?
https://www.mail-archive.com/qemu-devel@nongnu.org/msg777719.html
I have now moved the cpus into the tcg directory:
# ./qemu-system-aarch64 -cpu ?
Available CPUs:
a64fx
cortex-a35
cortex-a53
cortex-a55
cortex-a57
cortex-a72
cortex-a76
host
max
neoverse-n1
What remains is changing the Kconfig to not bring all the
machines. Nowadays for KVM is the 'virt' machine the only one we use? I
did some tests yesterday by keeping only CONFIG_ARM_VIRT and was left
with this:
# ./qemu-system-aarch64 -machine ?
Supported machines are:
none empty machine
virt-2.10 QEMU 2.10 ARM Virtual Machine
virt-2.11 QEMU 2.11 ARM Virtual Machine
virt-2.12 QEMU 2.12 ARM Virtual Machine
virt-2.6 QEMU 2.6 ARM Virtual Machine
virt-2.7 QEMU 2.7 ARM Virtual Machine
virt-2.8 QEMU 2.8 ARM Virtual Machine
virt-2.9 QEMU 2.9 ARM Virtual Machine
virt-3.0 QEMU 3.0 ARM Virtual Machine
virt-3.1 QEMU 3.1 ARM Virtual Machine
virt-4.0 QEMU 4.0 ARM Virtual Machine
virt-4.1 QEMU 4.1 ARM Virtual Machine
virt-4.2 QEMU 4.2 ARM Virtual Machine
virt-5.0 QEMU 5.0 ARM Virtual Machine
virt-5.1 QEMU 5.1 ARM Virtual Machine
virt-5.2 QEMU 5.2 ARM Virtual Machine
virt-6.0 QEMU 6.0 ARM Virtual Machine
virt-6.1 QEMU 6.1 ARM Virtual Machine
virt-6.2 QEMU 6.2 ARM Virtual Machine
virt-7.0 QEMU 7.0 ARM Virtual Machine
virt-7.1 QEMU 7.1 ARM Virtual Machine
virt-7.2 QEMU 7.2 ARM Virtual Machine
virt QEMU 8.0 ARM Virtual Machine (alias of virt-8.0)
virt-8.0 QEMU 8.0 ARM Virtual Machine
x-remote Experimental remote machine
But qtest dislikes that even more. I need to figure out why.
The approach of that series seems interesting, moving CONFIG_FOO=y from
default.mak into Kconfig as 'default y if TCG'. Maybe that will yield
better results, I'll try to follow that route.

Inline marker non-functional.
Anyway, this should not be separated from cpu_get_tb_cpu_state, where it folds to no-op
when --disable-debug-tcg. Indeed, I once had it textually inlined in
cpu_get_tb_cpu_state, before Philippe thought it looked nicer as a separate helper function.
Otherwise,

It seems not, sbsa_ref_init has this:
if (kvm_enabled()) {
error_report("sbsa-ref: KVM is not supported for this machine");

I think perhaps also xlnx-versal-virt -- at any rate, the source
files include some KVM related headers...
Alistair, Edgar -- does xlnx-versal-virt work with KVM ?
