[Qemu-devel] New arm9 Emulation

[Andreas Koerner]

Hello!

 

I’m new to qemu and this list, so it’s nice to meet you.

 

My current job is to implement a developing platform for a STR910FAW32. This is an SoC with an ARM9-type CPU.

I would like to use qemu as simulation platform, as it is really active and does support arm9 type cpu’s.

A look at the mailing list archives shows that qemu machines are heavily modified and worked on in the younger past, but this does not seem to be in the master branch of the savannah repo?!?

As there is rarely documentation present, I simply started with the master revision (Friday) from the savannah repository, wrote a str910faw32.c put it in the hw directory and registered it  with “obj-arm-y += str910faw32.o” in Makefile.target.

 

Str910faw32.c:

 

#include "module.h"

#include "sysbus.h"

#include "primecell.h"

#include "devices.h"

#include "sysemu.h"

#include "boards.h"

#include "arm-misc.h"

 

static void str910faw32_init(ram_addr_t ram_size,

                     const char *boot_device,

                     const char *kernel_filename, const char *kernel_cmdline,

                     const char *initrd_filename, const char *cpu_model)

{

        fprintf(stderr, "Works!\n");

        exit(1);

}

 

static QEMUMachine str910faw32_machine = {

    .name = "str910faw32",

    .desc = "STR910FAW32 System on a Chip (ARM966E-S Core)",

    .init = str910faw32_init,

};

 

static void str910faw32_machine_init(void)

{

                    qemu_register_machine(&str910faw32_machine);

}

 

machine_init(str910faw32_machine_init);

 

But after a “sudo make install” this machine dies not show up under the “-M ?” option, so what’s my mistake?

 

Thank you for your help
