[PATCH v2 0/7] hw/ppc: SysBus simplifications

Posted by Philippe Mathieu-Daudé 1 year, 1 month ago

Hi,

There is no point in exposing an internal MMIO region via
SysBus and directly mapping it in the very same device.

This series replaces a sequence of:
- sysbus_init_mmio()
- sysbus_mmio_map()
by a single call to memory_region_add_subregion().

Since v1:
- New "Realize SPAPR_VIO_BRIDGE device before accessing it" patch
- Added R-b tags

Philippe Mathieu-Daudé (7):
  hw/ppc/spapr_vio: Realize SPAPR_VIO_BRIDGE device before accessing it
  hw/ppc/pnv_xscom: Rename pnv_xscom_realize(Error **) ->
    pnv_xscom_init()
  hw/ppc/pnv_xscom: Move sysbus_mmio_map() call within pnv_xscom_init()
  hw/ppc/pnv_xscom: Do not use SysBus API to map local MMIO region
  hw/ppc/pnv: Do not use SysBus API to map local MMIO region
  hw/intc/spapr_xive: Move sysbus_init_mmio() calls around
  hw/intc/spapr_xive: Do not use SysBus API to map local MMIO region
