Missing review: patch #7
Hi,
This series is inspired on Claudio TCG work.
Instead of separate TCG from other accelerators, here we
separate sysemu operations (system VS user).
Patches 1-5 are generic cleanups.
Patches 6-14 move from CPUClass to SysemuCPUOps
Patch 15 restricts SysemuCPUOps to sysemu
Since v4:
- Removed watchpoint patches (need more work) (Richard)
- Merged patch 1 & 7 "Move CPUClass::vmsd to SysemuCPUOps" (Eduardo)
- Reworded cpu_virtio_is_big_endian description (Greg)
- Move write_elf() in target/riscv/cpu.c (rebased on top of 43a965888)
- Added R-b tags
Since v3:
- SysemuCPUOps const (Richard)
- added missing xtensa #ifdef'ry
- added missing aa64/sve #ifdef'ry
- added Laurent R-b
Since v2:
- fixed lm32/unicore32
- remove USER_ONLY ifdef'ry from "cpu.h" (Claudio)
Since v1:
- Name 'sysemu' (Claudio)
- change each field progressively (Richard)

To be able to later extract the cpu_get_phys_page_debug() and
cpu_asidx_from_attrs() handlers from CPUClass, un-inline them
from "hw/core/cpu.h".

Introduce the cpu_virtio_is_big_endian() generic helper to avoid
calling CPUClass internal virtio_is_big_endian() one.
Similarly to commit bf7663c4bd8 ("cpu: introduce
CPUClass::virtio_is_big_endian()"), we keep 'virtio' in the method
name to hint this handler shouldn't be called anywhere but from the
virtio code.

Migration is specific to system emulation.
- Move the CPUClass::vmsd field to SysemuCPUOps,
- restrict VMSTATE_CPU() macro to sysemu,
- vmstate_dummy is now unused, remove it.
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since v3: Merged in patch 1 (Eduardo)
therefore removed Richard R-b.
'vmsd' is not a 'system operation' prototype but a const
pointer field, so it belongs to a const structure,
but maybe this structure could be better named than SysemuCPUOps?
This field comes from:
commit b170fce3dd06372f7bfec9a780ebcb1fce6d57e4
Author: Andreas Färber <afaerber@suse.de>
Date: Sun Jan 20 20:23:22 2013 +0100
cpu: Register VMStateDescription through CPUState
In comparison to DeviceClass::vmsd, CPU VMState is split in two,
"cpu_common" and "cpu", and uses cpu_index as instance_id instead of -1.
Therefore add a CPU-specific CPUClass::vmsd field.
Unlike the legacy CPUArchState registration, rather register CPUState.

Migration is specific to system emulation.
- Move the CPUClass::vmsd field to SysemuCPUOps,
- restrict VMSTATE_CPU() macro to sysemu,
- vmstate_dummy is now unused, remove it.
Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since v3: Merged in patch 1 (Eduardo)
therefore removed Richard R-b.
'vmsd' is not a 'system operation' prototype but a const
pointer field, so it belongs to a const structure,
but maybe this structure could be better named than SysemuCPUOps?
This field comes from:
commit b170fce3dd06372f7bfec9a780ebcb1fce6d57e4
Author: Andreas Färber <afaerber@suse.de>
Date: Sun Jan 20 20:23:22 2013 +0100
cpu: Register VMStateDescription through CPUState
In comparison to DeviceClass::vmsd, CPU VMState is split in two,
"cpu_common" and "cpu", and uses cpu_index as instance_id instead of -1.
Therefore add a CPU-specific CPUClass::vmsd field.
Unlike the legacy CPUArchState registration, rather register CPUState.

Somehow similar to commit 78271684719 ("cpu: tcg_ops: move to
tcg-cpu-ops.h, keep a pointer in CPUClass"):
We cannot in principle make the SysEmu Operations field definitions
conditional on CONFIG_SOFTMMU in code that is included by both
common_ss and specific_ss modules.
Therefore, what we can do safely to restrict the SysEmu fields to
system emulation builds, is to move all sysemu operations into a
separate header file, which is only included by system-specific code.
This leaves just a NULL pointer in the cpu.h for the user-mode builds.

Somehow similar to commit 78271684719 ("cpu: tcg_ops: move to
tcg-cpu-ops.h, keep a pointer in CPUClass"):
We cannot in principle make the SysEmu Operations field definitions
conditional on CONFIG_SOFTMMU in code that is included by both
common_ss and specific_ss modules.
Therefore, what we can do safely to restrict the SysEmu fields to
system emulation builds, is to move all sysemu operations into a
separate header file, which is only included by system-specific code.
This leaves just a NULL pointer in the cpu.h for the user-mode builds.
