[PATCH v1 0/1] Optimizing the print format of the QEMU monitor info mtree

Posted by Chao Liu 6 months, 2 weeks ago

Hi, all:

Currently info mtre prints the memory-region hierarchy using two spaces as
indentation, which is not very clear when there are too many nodes.

```
(qemu) info mtree

memory-region: system
  0000000000000000-ffffffffffffffff (prio 0, i/o): system
    0000000000001000-000000000000ffff (prio 0, rom): riscv_virt_board.mrom
    0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport_window
      0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport
...
    0000000040000000-000000007fffffff (prio 0, i/o): alias ...
    0000000080000000-0000000087ffffff (prio 0, ram): riscv_virt_board.ram
    0000000400000000-00000007ffffffff (prio 0, i/o): alias ...
```

Therefore, I optimized the print format of this command to be similar to the
tree command, so that it can better distinguish multi-level memory-region nodes.

```
(qemu) info mtree

memory-region: system
│  ├── 0000000000000000-ffffffffffffffff (prio 0, i/o): system
│  │   ├── 0000000000001000-000000000000ffff (prio 0, rom): riscv_virt_board.mrom
│  │   ├── 0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport_window
│  │   │   └── 0000000003000000-000000000300ffff (prio 0, i/o): gpex_ioport
...
│  │   ├── 0000000040000000-000000007fffffff (prio 0, i/o): alias ...
│  │   ├── 0000000080000000-0000000087ffffff (prio 0, ram): riscv_virt_board.ram
│  │   └── 0000000400000000-00000007ffffffff (prio 0, i/o): alias ...
```
