3ARM System emulator
4-------------------

6Use the executable ``qemu-system-arm`` to simulate a ARM machine. The
7ARM Integrator/CP board is emulated with the following devices:
8
9-  ARM926E, ARM1026E, ARM946E, ARM1136 or Cortex-A8 CPU
10
11-  Two PL011 UARTs
12
13-  SMC 91c111 Ethernet adapter
14
15-  PL110 LCD controller
16
17-  PL050 KMI with PS/2 keyboard and mouse.
18
19-  PL181 MultiMedia Card Interface with SD card.

21The ARM Versatile baseboard is emulated with the following devices:
22
23-  ARM926E, ARM1136 or Cortex-A8 CPU
24
25-  PL190 Vectored Interrupt Controller

29-  SMC 91c111 Ethernet adapter
30
31-  PL110 LCD controller
32
33-  PL050 KMI with PS/2 keyboard and mouse.
34
35-  PCI host bridge. Note the emulated PCI bridge only provides access
36   to PCI memory space. It does not provide access to PCI IO space. This
37   means some devices (eg. ne2k_pci NIC) are not usable, and others (eg.
38   rtl8139 NIC) are only usable when the guest drivers use the memory
39   mapped control registers.
40

47
48Several variants of the ARM RealView baseboard are emulated, including
49the EB, PB-A8 and PBX-A9. Due to interactions with the bootloader, only
50certain Linux kernel configurations work out of the box on these boards.
51
52Kernels for the PB-A8 board should have CONFIG_REALVIEW_HIGH_PHYS_OFFSET
53enabled in the kernel, and expect 512M RAM. Kernels for The PBX-A9 board
54should have CONFIG_SPARSEMEM enabled, CONFIG_REALVIEW_HIGH_PHYS_OFFSET
55disabled and expect 1024M RAM.
56
