[PATCH 0/7] system/memory: Improve 'info mtree' readability

Posted by Philippe Mathieu-Daudé 3 days, 8 hours ago

Cleaning dust, I had forgotten about this branch. In short,
it improves 'info mtree' readability of addresses.

Currently with Q35:

    address-space: I/O
      0000000000000000-000000000000ffff (prio 0, i/o): io
          0000000000000000-0000000000000003 (prio 0, i/o): acpi-evt
          0000000000000004-0000000000000005 (prio 0, i/o): acpi-cnt
          0000000000000008-000000000000000b (prio 0, i/o): acpi-tmr
          0000000000000020-000000000000002f (prio 0, i/o): acpi-gpe0
          0000000000000030-0000000000000037 (prio 0, i/o): acpi-smi
          0000000000000060-000000000000007f (prio 0, i/o): sm-tco
        0000000000000000-0000000000000007 (prio 0, i/o): dma-chan
        0000000000000008-000000000000000f (prio 0, i/o): dma-cont
        0000000000000020-0000000000000021 (prio 0, i/o): pic
        0000000000000040-0000000000000043 (prio 0, i/o): pit
        ...
    memory-region: pc.ram
      0000000000000000-0000000007ffffff (prio 0, ram): pc.ram
    memory-region: pc.bios
      00000000fffc0000-00000000ffffffff (prio 0, rom): pc.bios
    memory-region: pci
      0000000000000000-ffffffffffffffff (prio -1, i/o): pci
        00000000000a0000-00000000000bffff (prio 1, i/o): vga-lowmem
        00000000000c0000-00000000000dffff (prio 1, rom): pc.rom
        00000000000e0000-00000000000fffff (prio 1, rom): alias isa-bios @pc.bios 0000000000020000-000000000003ffff
        00000000fffc0000-00000000ffffffff (prio 0, rom): pc.bios

Philippe Mathieu-Daudé (7):
  stubs: Merge physmem.c within ram-block.c
  system/ramblock: Constify various RAMBlock arguments
  system/memory: Constify various MemoryRegion arguments
  system/memory: Have memory_region_type() correctly describe containers
  system/memory: Display address spaces starting at 0x0000.0000
  system/memory: Allow mtree_print_mr() to display distinct address
    width
  system/memory: Have 'info mtree' display addresses nicely
