| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the CPUClass:gdb_core_xml_file setting is a simple 'const char *' which the CPU class must set to a fixed string. Allow the CPU class to instead set a new method gdb_get_core_xml_file() which returns this string. This will allow Arm CPUs to use different XML files for AArch32 vs AArch64 without having to have an extra AArch64-specific class type purely to give somewhere to set cc->gdb_core_xml_file differently.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gather all VFIORegion related declarations and definitions into their own files to reduce exposure of VFIO internals in "hw/vfio/vfio-common.h". They were introduced for 'vfio-platform' support in commits db0da029a185 ("vfio: Generalize region support") and a664477db8da ("hw/vfio/pci: Introduce VFIORegion"). To be noted that the 'vfio-platform' devices have been deprecated and will be removed in QEMU 10.2. Until then, make the declarations available externally for 'sysbus-fdt.c'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The migration core subsystem makes use of the VFIO migration API to collect statistics on the number of bytes transferred. These services are declared in "hw/vfio/vfio-common.h" which also contains VFIO internal declarations. Move the migration declarations into a new header file "hw/vfio/vfio-migration.h" to reduce the exposure of VFIO internals. While at it, use a 'vfio_migration_' prefix for these services. To be noted, vfio_migration_add_bytes_transferred() is a VFIO migration internal service which we will be moved in the subsequent patches.
