[Qemu-devel] [PATCH v3 00/25] generalize parsing of cpu_model (part 4)

[Qemu-devel] [PATCH v3 00/25] generalize parsing of cpu_model (part 4)

[Igor Mammedov]

v3:
  - use qtest_startf() instead of qtest_start()
  - rename tests/machine-none.c to tests/machine-none-test.c
  - introduce first CPU_RESOLVING_TYPE for all targets and
    only then use it parse_cpu_model() 
  - stop abusing  mc->default_cpu_type as resolving cpu type,
    move cpu_parse_cpu_model() in to exec.c and embed in
    CPU_RESOLVING_TYPE, so that callers won't have to know
    about unnecessary detail

v2:
  - implemented new approach only for x86/ARM (will be done for all targets
    if approach seems acceptable)
  - add test case for '-M none -cpu FOO' case
  - redefine TARGET_DEFAULT_CPU_TYPE into CPU_RESOLVING_TYPE
  - scrape off default cpu_model refactoring, so it would cause
    less conflicts with Laurent's series where he tries to rework
    defaults to use ELF hints of executed program

Series is finishing work on generalizing cpu_model parsing
and limiting parts that deal with inconsistent cpu_model
naming to "-cpu" CLI option in vl.c, bsd|linux-user/main.c
CLI and default cpu_model processing and FOO_cpu_class_by_name()
callbacks.

It introduces CPU_RESOLVING_TYPE which must be defined
by each target and is used by helper parse_cpu_model()
(former cpu_parse_cpu_model()) to get access to target
specific FOO_cpu_class_by_name() callback.

[Qemu-devel] [PATCH v3 10/25] mips: cpu: add CPU_RESOLVING_TYPE macro

[Igor Mammedov]

it will be used for providing to cpu name resolving class for
parsing cpu model for system and user emulation code.

Along with change add target to null-machine test, so
that when switch to CPU_RESOLVING_TYPE happens,
test would ensure that null-mchine usecase still works.

[Qemu-devel] [PATCH v3 22/25] tilegx: cpu: add CPU_RESOLVING_TYPE macro

[Igor Mammedov]

it will be used for providing to cpu name resolving class for
parsing cpu model for system and user emulation code.

Along with change add target to null-machine test, so
that when switch to CPU_RESOLVING_TYPE happens,
test would ensure that null-mchine usecase still works.

[Qemu-devel] [PATCH v3 23/25] Use cpu_create(type) instead of cpu_init(cpu_model)

[Igor Mammedov]

With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.

That allows us to stop abusing cpu type from
  MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().

Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.

[Qemu-devel] [PATCH v3 24/25] cpu: get rid of unused cpu_init() defines

[Igor Mammedov]

cpu_init(cpu_model) were replaced by cpu_create(cpu_type) so
no users are left, remove it.

I understand that this doesn't matter for your purposes, but can we change
the aarch64 mapping to point to an aarch64 processor, e.g. cortex-a57,
instead?

Thanks,

[Qemu-devel] [PATCH v4 03/25] arm: cpu: add CPU_RESOLVING_TYPE macro

[Igor Mammedov]

it will be used for providing to cpu name resolving class for
parsing cpu model for system and user emulation code.

Along with change add target to null-machine test, so
that when switch to CPU_RESOLVING_TYPE happens,
thest would ensure that null-mchine usecase still works.

[Qemu-devel] [PATCH v4 23/25] Use cpu_create(type) instead of cpu_init(cpu_model)

[Igor Mammedov]

With all targets defining CPU_RESOLVING_TYPE, refactor
cpu_parse_cpu_model(type, cpu_model) to parse_cpu_model(cpu_model)
so that callers won't have to know internal resolving cpu
type. Place it in exec.c so it could be called from both
target independed vl.c and *-user/main.c.

That allows us to stop abusing cpu type from
  MachineClass::default_cpu_type
as resolver class in vl.c which were confusing part of
cpu_parse_cpu_model().

Also with new parse_cpu_model(), the last users of cpu_init()
in null-machine.c and bsd/linux-user targets could be switched
to cpu_create() API and cpu_init() API will be removed by
follow up patch.

With no longer users left remove MachineState::cpu_model field,
new code should use MachineState::cpu_type instead and
leave cpu_model parsing to generic code in vl.c.

v4:
  - actually remove no longer used MachineState::cpu_model field
    that I've lost somewhere during respins

  - squash in [PATCH v3 25/25] cpu: get rid of cpu_generic_init()
    as after rework/rebase cpu_generic_init() is being removed by
    this patch and only check removal was left in 25/25, which
    should be removed together with cpu_generic_init() in this patch

after rebase this patch nor longer does what subj says
and it should be squashed into 23/25 where cpu_generic_init() is removed,
so pls ignore this patch I'll post v4 for 23/25 with this squashed in
and actual removal of not used MachineState::cpu_model
which I've lost on rebase.

I'm unsure if it's OK to purposefully have intermediate commits
that will generate warnings on "make check".  It could confuse
people doing bisects.

I would prefer to add this warning only after all targets are
converted.  Or maybe only add this test code after all targets
are converted.

Why are we testing only a single CPU model on each target (and
requiring one entry for each architecture in this table), instead
of just running query-cpu-definitions and testing all CPU models?

Suggestion: replace this with assert(!cpu_globals_initialized)
just to make sure there are no bugs that make us register CPU
globals twice.

This shouldn't block the patch, though:

Re: [Qemu-devel] [PATCH v3 00/25] generalize parsing of cpu_model (part 4)

[Eduardo Habkost]

I will try to summarize my comments here:

* I suggest squashing patches 2-22 together.  This way we
  shouldn't have any intermediate commits where "make check"
  generates warnings, and the series is shorter.
  * Or, even better: squash the CPU_RESOLVING_TYPE parts of 3-22
    into one patch, and the tests/machine-none-test.c parts of
    3-22 into patch 2.

* The linux-user/main.c hunk of patch 03/25 looks unnecessary.

* I suggest testing all CPU models in patch 02/25, but this
  shouldn't block the series.  Can be a follow-up patch.

All the rest looks good to me.

Thanks!

CPU_RESOLVING_TYPE parts we split to simplify review

I'll respin squashing them into one commit.

Indeed, I think it was a leftover slipped in from previous revision
where I was touching default cpus handling in *-user targets,
with the later dropped from series it's not needed.

the goal of the test is that refactoring didn't regress
'none' machine after following change in 23/25:

@@ -24,9 +24,9 @@ static void machine_none_init(MachineState *mch)
 {
     CPUState *cpu = NULL;
 
-    /* Initialize CPU (if a model has been specified) */
-    if (mch->cpu_model) {
-        cpu = cpu_init(mch->cpu_model);
+    /* Initialize CPU (if user asked for it) */
+    if (mch->cpu_type) {
+        cpu = cpu_create(mch->cpu_type);

for that it's sufficient to probe one cpu model.

We can do all cpus probing later if there will be need in it,
but that's not related to this series and would just waste
'make check' time if it won't be doing something meaningful
with probed cpu.

Not making "make check" slow is a good argument, I agree.

Extensive testing like testing all CPU models or all devices
probably should be done in a separate (slower) test set.
