[PATCH v3 0/6] target/ppc: Few cleanups in kvm_ppc.h

[Philippe Mathieu-Daudé]

PPC specific changes of a bigger KVM cleanup, remove "kvm_ppc.h"
from user emulation. Mostly trivial IMO.

Philippe Mathieu-Daudé (6):
  target/ppc: Have 'kvm_ppc.h' include 'sysemu/kvm.h'
  target/ppc: Reorder #ifdef'ry in kvm_ppc.h
  target/ppc: Move CPU QOM definitions to cpu-qom.h
  target/ppc: Define TYPE_HOST_POWERPC_CPU in cpu-qom.h
  target/ppc: Restrict 'kvm_ppc.h' to sysemu in cpu_init.c
  target/ppc: Remove pointless checks of CONFIG_USER_ONLY in 'kvm_ppc.h'

[PATCH v3 1/6] target/ppc: Have 'kvm_ppc.h' include 'sysemu/kvm.h'

[Philippe Mathieu-Daudé]

"kvm_ppc.h" declares:

  int kvm_handle_nmi(PowerPCCPU *cpu, struct kvm_run *run);

'struct kvm_run' is declared in "sysemu/kvm.h", include it.

[PATCH v3 4/6] target/ppc: Define TYPE_HOST_POWERPC_CPU in cpu-qom.h

[Philippe Mathieu-Daudé]

TYPE_HOST_POWERPC_CPU is used in various places of cpu_init.c,
in order to restrict "kvm_ppc.h" to sysemu, move this QOM-related
definition to cpu-qom.h.

I guess the MemoryRegion code has sufficiently changed since commit
98efaf75282a ("ppc: Fix up usermode only builds") ?

Greg has a point:

$ git grep '#define cpu_list'
target/alpha/cpu.h:#define cpu_list alpha_cpu_list
target/arm/cpu.h:#define cpu_list arm_cpu_list
target/avr/cpu.h:#define cpu_list avr_cpu_list
target/cris/cpu.h:#define cpu_list cris_cpu_list
target/hexagon/cpu.h:#define cpu_list hexagon_cpu_list

target/mips/cpu.h:#define cpu_list mips_cpu_list
target/openrisc/cpu.h:#define cpu_list cpu_openrisc_list
target/ppc/cpu.h:#define cpu_list ppc_cpu_list
target/riscv/cpu.h:#define cpu_list riscv_cpu_list
target/rx/cpu.h:#define cpu_list rx_cpu_list
target/s390x/cpu.h:#define cpu_list s390_cpu_list
target/sh4/cpu.h:#define cpu_list sh4_cpu_list
target/sparc/cpu.h:#define cpu_list sparc_cpu_list
target/tricore/cpu.h:#define cpu_list tricore_cpu_list
target/xtensa/cpu.h:#define cpu_list xtensa_cpu_list

I'm not against moving this define to cpu-qom.h per se but I believe that, for the sake
of consistency, this change should be done in a single swoop across all archs.

For now, if you agree with keeping the 'cpu_list' define in cpu.h, I'll queue this up
and amend it in-tree.


Thanks,

Daniel

Re: [PATCH v3 0/6] target/ppc: Few cleanups in kvm_ppc.h

Phil,

I queued all patches to ppc-next. I fixed up patch 3 to not move the cpu_list
macro as Greg suggested. If you're strongly attached to it let me know and
I'll remove it from the queue.

Greg, feel free to send your R-b in patch 3 if patch 3 with this change pleases
you.
