[Qemu-devel] qemu+systemc

[Damien Bardon]

Hello,

My idea isn't new, but I would like to interface SystemC with Qemu. To begin I 
had a look at the ARM architecture with the Amba bus. I now there is already 
an existing work on this subject but :

-> I would like a TLM 2.0 interface (OSCI standard)
-> It uses BSD sockets... I'm not sure it is very efficient ?
-> The current patch looks quite ugly ?

What I need is quite simle
-> a hook to the amba read/write requests
-> a way of synchronizing systemC and Qemu, so I need some knowledge about 
Qemu time.

Do you think you could give me some hints to get a fast start ?

Also the following line in hw/integratorcp.c looks like Qemu for ARM is 
designed for a linux kernel only ? Am I wrong ? Is it possible to execute the 
ISS without operating system ?

arm_load_kernel(env, ram_size, kernel_filename, kernel_cmdline,
                    initrd_filename, 0x113, 0x0);

Thank you.

Damien

Hi all,

Recently I am struggling in examing the effect of host kernel I/O stacks on
high-speed SSD, especially the new PCIe SSD, without the availability of
the necessary hardware. After several reading online I found out
QEMU+SystemC model environment might be able to to solve my problem.

Sorry I am new to QEMU. My main objective is to collect guest OS statistics
based on the attached external SSD model. So simple SystemC stub will be
the best for my case. Can anybody give me any suggestion on which QEMU
variant with SystemC fit me the best? I will sincerely appreciate that if
you could forward me the correct URL for download also.

Thank you for your attention,

Sean Xie

Hi,

We made a SystemC wrapper for QEMU with some limitations and a QEMU
version which is a little old now.

Maybe that can suit your need, what kind of statistics do you want to get
from the guest?

Thanks,
Fred
