Subject: [PATCH 00/15] system/physmem: Remove cpu_physical_memory _is_io() and _rw()
Date: Mon, 29 Sep 2025 20:32:39 +0200	[thread overview]
Message-ID: <20250929183254.85478-1-philmd@linaro.org> (raw)

The cpu_physical_memory API is legacy (see commit b7ecba0f6f6):

  ``cpu_physical_memory_*``
  ~~~~~~~~~~~~~~~~~~~~~~~~~

  These are convenience functions which are identical to
  ``address_space_*`` but operate specifically on the system address space,
  always pass a ``MEMTXATTRS_UNSPECIFIED`` set of memory attributes and
  ignore whether the memory transaction succeeded or failed.
  For new code they are better avoided:
  ...

This series removes:
  - cpu_physical_memory_is_io()
  - cpu_physical_memory_rw()
and start converting some
  - cpu_physical_memory_map()
  - cpu_physical_memory_unmap()
calls.

Based-on: <20250922192940.2908002-1-richard.henderson@linaro.org>
          "system/memory: Split address_space_write_rom_internal"

Philippe Mathieu-Daudé (15):
  docs/devel/loads-stores: Stop mentioning
    cpu_physical_memory_write_rom()
  system/memory: Factor address_space_memory_is_io() out
  target/i386/arch_memory_mapping: Use address_space_memory_is_io()
  hw/s390x/sclp: Use address_space_memory_is_io() in sclp_service_call()
  system/physmem: Remove cpu_physical_memory_is_io()
  system/physmem: Pass address space argument to
    cpu_flush_icache_range()
  target/s390x/mmu: Replace [cpu_physical_memory -> address_space]_rw()
  target/i386/whpx: Replace legacy cpu_physical_memory_rw() call
  target/i386/kvm: Replace legacy cpu_physical_memory_rw() call
  target/i386/nvmm: Inline cpu_physical_memory_rw() in nvmm_mem_callback
  hw/xen/hvm: Inline cpu_physical_memory_rw() in rw_phys_req_item()
  system/physmem: Un-inline cpu_physical_memory_read/write()
  system/physmem: Inline cpu_physical_memory_rw() and remove it
  hw/virtio/vhost: Replace legacy cpu_physical_memory_*map() calls
  hw/virtio/virtio: Replace legacy cpu_physical_memory_map() call
