This code is not related to hardware emulation. Move it under accel/ with the other hypervisors. Reviewed-by: Paul Durrant <paul@xxxxxxx> Signed-off-by: Philippe Mathieu-Daudé <philmd@xxxxxxxxxx> --- We could also move the memory management functions from hw/i386/xen/xen-hvm.c but it is not trivial. v2: Use g_assert_not_reached() instead of abort() v3: (quintela) - Do not expose xen_allowed - Do not abort in xen_hvm_modified_memory --- include/exec/ram_addr.h | 2 +- include/hw/xen/xen.h | 11 ------- include/sysemu/xen.h | 38 ++++++++++++++++++++++ hw/xen/xen-common.c => accel/xen/xen-all.c | 8 +++++ hw/acpi/piix4.c | 2 +- hw/i386/pc.c | 1 + hw/i386/pc_piix.c | 1 + hw/i386/pc_q35.c | 1 + hw/i386/xen/xen-hvm.c | 1 + hw/i386/xen/xen_platform.c | 1 + hw/isa/piix3.c | 1 + hw/pci/msix.c | 1 + migration/savevm.c | 2 +- softmmu/vl.c | 2 +- stubs/xen-hvm.c | 9 ----- target/i386/cpu.c | 2 +- MAINTAINERS | 2 ++ accel/Makefile.objs | 1 + accel/xen/Makefile.objs | 1 + hw/xen/Makefile.objs | 2 +- 20 files changed, 63 insertions(+), 26 deletions(-) create mode 100644 include/sysemu/xen.h rename hw/xen/xen-common.c => accel/xen/xen-all.c (98%) create mode 100644 accel/xen/Makefile.objs diff --git a/include/exec/ram_addr.h b/include/exec/ram_addr.h index 5e59a3d8d7..4e05292f91 100644 --- a/include/exec/ram_addr.h +++ b/include/exec/ram_addr.h @@ -21,7 +21,7 @@ #ifndef CONFIG_USER_ONLY #include "cpu.h" -#include "hw/xen/xen.h" +#include "sysemu/xen.h" #include "sysemu/tcg.h" #include "exec/ramlist.h" #include "exec/ramblock.h" diff --git a/include/hw/xen/xen.h b/include/hw/xen/xen.h index 5ac1c6dc55..771dd447f2 100644 --- a/include/hw/xen/xen.h +++ b/include/hw/xen/xen.h @@ -20,13 +20,6 @@ extern uint32_t xen_domid;
