Re: [XenARM] [Patch] ARM Versatile PB support

["Jang, Minsung" <minsung@xxxxxxxxxx>]

Hello, Parth,

What I use on qemu is
[minsung@acadia]$ qemu-system-arm -M versatilepb -m 192 -s -pflash flash.img

As you probably know, arguments means
-M: selection of board
-m: emulated memory size
-s: enabling debugging support
-pflash: use flash image as booting device

flash.img is a NOR flash image file that contains the binaries of u-boot(bootloader), XenARM, and MiniOS.
You can make your own flash.img by 'dd' command in Linux.

As I mentioned before, since QEMU does not emulate flash memory properly in some boards, for example, Versatile PB,
you must apply patches from http://thomas.enix.org/Blog-20081002153859-Technologie. After patching, you can use '-pflash' option.

Thank you.
Minsung

Hi Minsung,

I am a student at UCLA working on Xen-Arm related project. Thank you for this patch. I have been trying to run various versions of Xen-Arm on QEMU. However, I have not had any success. Can you let me know the exact whole command that you use to run this on qemu-system-arm?

Thank You.

Hi all,

I am very pleased to submit new patch for platform support of XenARM.
This patch includes ARM Versatile Platform Board(PB) support codes and bug fix of XenARM.

The limitations of the patch are as follows:
 - Supports only upper 64MB of RAM on board (0x04000000-0x08000000)
  in order to avoid the conflict with domain creation codes in XenARM.
  I expect the conflict will be resolved by XenARM maintainers in near future.
 - Supports only the first Vector Interrupt Controller(VIC)

It also has been implemented and tested at the below environments
 - QEMU 0.9.1
 - u-boot 1.3.4

In addition, current version of QEMU doesn't support a flash memory and network interface of Versatile PB properly, so that you must apply patches into QEMU, and u-boot in order to use this . Please refer http://thomas.enix.org/Blog-20081002153859-Technologie about that.

For more details, you can find at $(XEN_ROOT)/xen/arch/arch-versatile/README.

Thank you,
Minsung
