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 1-6 are generic cleanups.
Patches 7-15 move from CPUClass to SysemuCPUOps
Patches 16-17 restrict SysemuCPUOps to sysemu
Since v1:
- Name 'sysemu' (Claudio)
- change each field progressively (Richard)
Regards,
Phil.
Supersedes: <20210226163227.4097950-1-f4bug@amsat.org>
Philippe Mathieu-Daudé (17):
target: Set CPUClass::vmsd instead of DeviceClass::vmsd
cpu: Un-inline cpu_get_phys_page_debug and cpu_asidx_from_attrs
cpu: Introduce cpu_virtio_is_big_endian()
cpu: Directly use cpu_write_elf*() fallback handlers in place
cpu: Directly use get_paging_enabled() fallback handlers in place
cpu: Directly use get_memory_mapping() fallback handlers in place
cpu: Introduce SysemuCPUOps structure
cpu: Move CPUClass::vmsd to SysemuCPUOps
cpu: Move CPUClass::virtio_is_big_endian to SysemuCPUOps
cpu: Move CPUClass::get_crash_info to SysemuCPUOps
cpu: Move CPUClass::write_elf* to SysemuCPUOps
cpu: Move CPUClass::asidx_from_attrs to SysemuCPUOps
cpu: Move CPUClass::get_phys_page_debug to SysemuCPUOps
cpu: Move CPUClass::get_memory_mapping to SysemuCPUOps
cpu: Move CPUClass::get_paging_enabled to SysemuCPUOps
cpu: Restrict cpu_paging_enabled / cpu_get_memory_mapping to sysemu
cpu: Restrict "hw/core/sysemu-cpu-ops.h" to target/cpu.c

The cpu model is the single device available in user-mode.
Since we want to restrict some fields to user-mode emulation,
we prefer to set the vmsd field of CPUClass, rather than the
DeviceClass one.

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".

from "hw/core/cpu.h".

Hi Philippe,
this is the only patch where I was able to find an issue.
Adding any #ifdef CONFIG_USER_ONLY in include/hw/core/cpu.h as far as I experienced, is basically wrong.
Your use is not causing direct damage, but could be used as a precedent to introduce serious bugs.
It was the case for me.
Is there some other header, only included by target-specific code, that you could place these?
Ciao,
Claudio

Note I'm not strictly "adding" it but moving it.
I agree CONFIG_USER_ONLY shouldn't be used in hw/ (and sent 3 series
to clean this the last days).

I'll think about it, meanwhile we can also drop this patch, it is not
a requisite.
Thanks for your review,

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.
