Hello, this is version 12 of the cleanup (PART 1)
The series has been split into two separate parts,
and this is PART 1.
v11 -> v12:
* "cpu: Move synchronize_from_tb() to tcg_ops":
removed review tags, as there is currently a bunch of conflicting
requirements (Eduardo, Richard, Philippe).
in this iteration, tcg-cpu-ops.h is renamed to tcg-cpu-ops.h.inc,
and it is not expected to be included standalone as a header file,
instead it is just a split of cpu.h for the TCG-specific ops.
* "i386: move whpx accel files into whpx/" rebased on master
(trivial change) -> added whpx/apic.c
* "i386: move kvm accel files into kvm/" rebased on master
(trivial change) -> added some code and a default kvm parameter
to kvm/kvm-cpu.c
* "i386: move TCG accel files into tcg/":
(trivial change) -> moved cc_helper_template.h to tcg/ as well.
* "i386: move TCG cpu class initialization to tcg/":
comment better the additional moves of TCG specific defines
from cpu.h to helper-tcg.h.
cpu.h: do not touch CC_SRC and friends,
move FT0 and friends to tcg/fpu_helper.c.
create a new patch
"i386: tcg: remove inline from cpu_load_eflags".
(Richard)
* "cpu: Move tlb_fill to tcg_ops":
(trivial change) -> break line longer than 80 char
* "cpu: move cc->transaction_failed to tcg_ops:
(trivial change) -> break line longer than 80 char
v10 -> v11: split off PART 2,
no further changes to PART 2 other than the split.
v9 -> v10: minor tweaks and fixes
* in "i386: split cpu accelerators from cpu.c",
use kvm/kvm-cpu.c, hvf/hvf-cpu.c, tcg/tcg-cpu.c.
Easier to understand compared to editing multiple cpu.c files,
and matches the header files if needed (kvm-cpu.h).
* in "accel: replace struct CpusAccel with AccelOpsClass",
make it a bit more consistent, by naming the files defining
the AccelOpsClass types "...-accel-ops.c" instead of the old
naming "...-cpus.c".
* in "cpu: move cc->transaction_failed to tcg_ops",
protect with CONFIG_TCG the use of tcg_ops for hw/misc/jazz.c,
#include "exec/memattrs.h" (Philippe, Eduardo)
* in "cpu: Move synchronize_from_tb() to tcg_ops",
#include "hw/core/cpu.h" (Philippe, Eduardo)
do not remove the comment about struct TcgCpuOperations (Philippe)
* in "accel/tcg: split TCG-only code from cpu_exec_realizefn",
invert tcg_target_initialized set order (Alex)
* in "i386: move TCG cpu class initialization out of helper.c",
extract helper-tcg.h, tcg-cpu.c, and tcg-cpu.h directly into
tcg/, avoiding the extra move later to tcg/ (Alex)
v8 -> v9: move additional methods to CPUClass->tcg_ops
do_unaligned_access, transaction_failed and do_interrupt.
do_interrupt is a bit tricky, as the same code is reused
(albeit not usually directly) for KVM under certain odd conditions.
Change arm, as the only user of do_interrupt callback for KVM,
to instead call the target function directly arm_do_interrupt.
v7 -> v8: add missing CONFIG_TCGs, fix bugs
* add the prerequisite patches for "3 tcg" at the beginning of the
series for convenience (already reviewed, queued by RH).
* add CONFIG_TCG to TCGCpuOperations and tcg_ops variable use
* reduce the scope of the realizefn refactoring, do not
introduce a separate cpu_accel_realize, and instead use the
existing cpu_exec_realizefn, there is not enough benefit
to introduce a new function.
* fix bugs in user mode due to attempt to move the tcg_region_init()
early, so it could be done just once in tcg_init() for both
softmmu and user mode. Unfortunately it needs to remain deferred
for user mode, as it needs to be done after prologue init and
after the GUEST_BASE has been set.
v6 -> v7: integrate TCGCpuOperations, refactored cpu_exec_realizefn
* integrate TCGCpuOperations (Eduardo)
Taken some refactoring from Eduardo for Tcg-only operations on
CPUClass.
* refactored cpu_exec_realizefn
The other main change is a refactoring of cpu_exec_realizefn,
directly linked to the effort of making many cpu_exec operations
TCG-only (Eduardo series above):
cpu_exec_realizefn is actually a TCG-only thing, with the
exception of a couple things that can be done in base cpu code.
This changes all targets realizefn, so I guess I have to Cc:
the Multiverse? (Universe was already CCed for all accelerators).
v5 -> v6: remove MODULE_INIT_ACCEL_CPU
instead, use a call to accel_init_interfaces().
* The class lookups are now general and performed in accel/
new AccelCPUClass for new archs are supported as new
ones appear in the class hierarchy, no need for stubs.
* Split the code a bit better
v4 -> v5: centralized and simplified initializations
I put in Cc: Emilio G. Cota, specifically because in patch 8
I (re)moved for user-mode the call to tcg_regions_init().
The call happens now inside the tcg AccelClass machine_init,
(so earlier). This seems to work fine, but thought to get the
author opinion on this.
Rebased on "tcg-cpus: split into 3 tcg variants" series
(queued by Richard), to avoid some code churn:
https://lists.gnu.org/archive/html/qemu-devel/2020-10/msg04356.html
* Extended AccelClass to user-mode.
user-mode now does not call tcg_exec_init directly,
instead it uses the tcg accel class, and its init_machine method.
Since user-mode does not define or use a machine state,
the machine is just passed as NULL.
The immediate advantage is that now we can call current_accel()
from both user mode and softmmu, so we can work out the correct
class to use for accelerator initializations.
* QOMification of CpusAccelOps
simple QOMification of CpusAccelOps abstract class.
* Centralized all accel_cpu_init, so only one per cpu-arch,
plus one for all accels will remain.
So we can expect accel_cpu_init() to be limited to:
softmmu/cpus.c - initializes the chosen softmmu accel ops for the cpus module.
target/ARCH/cpu.c - initializes the chosen arch-specific cpu accelerator.
These changes are meant to address concerns/issues (Paolo):
1) the use of if (tcg_enabled()) and similar in the module_init call path
2) the excessive number of accel_cpu_init() to hunt down in the codebase.
* Fixed wrong use of host_cpu_class_init (Eduardo)
v3 -> v4: QOMification of X86CPUAccelClass
In this version I basically QOMified X86CPUAccel, taking the
suggestions from Eduardo as the starting point,
but stopping just short of making it an actual QOM interface,
using a plain abstract class, and then subclasses for the
actual objects.
Initialization is still using the existing qemu initialization
framework (module_call_init), which is I still think is better
than the alternatives proposed, in the current state.
Possibly some improvements could be developed in the future here.
In this case, effort should be put in keeping things extendible,
in order not to be blocked once accelerators also become modules.
Motivation and higher level steps:

to do this, we need to take code out of cpu.c and helper.c,
and also move some prototypes from cpu.h, for code that is
needed in tcg/xxx_helper.c, and which in turn is part of the
callbacks registered by the class initialization.
Therefore, do some shuffling of the parts of cpu.h that
are only relevant for tcg/, and put them in tcg/helper-tcg.h
For FT0 and similar macros, put them in tcg/fpu-helper.c
since they are used only there.

From: Eduardo Habkost <ehabkost@redhat.com>
The TCG-specific CPU methods will be moved to a separate struct,
to make it easier to move accel-specific code outside generic CPU
code in the future. Start by moving tcg_initialize().
The new CPUClass.tcg_opts field may eventually become a pointer,
but keep it an embedded struct for now, to make code conversion
easier.

From: Eduardo Habkost <ehabkost@redhat.com>
since tcg_cpu_ops.h is only included in cpu.h,
and as a standalone header it is not really useful,
as tcg_cpu_ops.h starts requiring cpu.h defines,
enums, etc, as well as (later on in the series),
additional definitions coming from memattr.h.
Therefore rename it to tcg_cpu_ops.h.inc, to warn
any potential user that this file is not a standalone
header, but rather a partition of cpu.h that is
included conditionally if CONFIG_TCG is true.

cc->do_interrupt is in theory a TCG callback used in accel/tcg only,
to prepare the emulated architecture to take an interrupt as defined
in the hardware specifications,
but in reality the _do_interrupt style of functions in targets are
also occasionally reused by KVM to prepare the architecture state in a
similar way where userspace code has identified that it needs to
deliver an exception to the guest.
In the case of ARM, that includes:
1) the vcpu thread got a SIGBUS indicating a memory error,
and we need to deliver a Synchronous External Abort to the guest to
let it know about the error.
2) the kernel told us about a debug exception (breakpoint, watchpoint)
but it is not for one of QEMU's own gdbstub breakpoints/watchpoints
so it must be a breakpoint the guest itself has set up, therefore
we need to deliver it to the guest.
So in order to reuse code, the same arm_do_interrupt function is used.
This is all fine, but we need to avoid calling it using the callback
registered in CPUClass, since that one is now TCG-only.
Fortunately this is easily solved by replacing calls to
CPUClass::do_interrupt() with explicit calls to arm_do_interrupt().

What's the benefit of moving definitions to a separate file, if
the new file is not a standalone header?
If moving the definitions to a separate header is going to
require too much work, it's completely OK to keep them in cpu.h
by now, and try to move them later.
I'm worried that the scope of this series is growing too much,
and discussion/review of additional changes in each new version
is preventing us from merging the original changes where we
already had some consensus.

Claudio, I haven't been following every respin. If you did that
change just to please me then the circular dependency remarked by
Richard, then if it simplify the series I'm OK if you have to
remove the includes.
Eduardo, if you are happy with patches 1-8 (x86 specific), maybe
you can queue them already. The rest is more TCG generic and
will likely go via Richard/Paolo trees IMO.

the benefit is avoiding a 100 line ifdef CONFIG_TCG, and already separating out what is tcg-specific and what isn't,
but if this is a problem we can avoid that, and revisit later on.

Richard, From the answer of Philippe and Eduardo I think they are not ok with .h.inc,
I think the option of just putting everything in cpu.h was ok with you,
should I go with that?
