Re: [Qemu-devel] More PCI ethernet emulations

[Stefan Weil <berlios@weilnetz.de>]

Hello,

these new ethernet drivers for QEMU are now available:

Intel 8255x ("E100", "EEPRO100"):
http://svn.berlios.de/wsvn/ar7-firmware/qemu/trunk/hw/eepro100.c?op=file

National Semiconductor DP83815/DP83816:
http://svn.berlios.de/wsvn/ar7-firmware/qemu/trunk/hw/dp8381x.c?op=file

Both drivers use a new EEPROM driver:
http://svn.berlios.de/wsvn/ar7-firmware/qemu/trunk/hw/eeprom93xx.c?op=file
http://svn.berlios.de/wsvn/ar7-firmware/qemu/trunk/hw/eeprom93xx.h?op=file

This EEPROM driver can be shared by any other device which needs
an EEPROM, for example replace the driver for RTL8139 or add an
EEPROM to cirrus vga or other ethernet cards.

I estimate the status of the EEPROM driver to be stable.
Fabrice, maybe this part can be integrated in QEMU head.

Both ethernet drivers work with QEMU head and Linux on x86 host / guest,
but have known endianess issues (they will at least need fixes for big
endian hosts) and are experimental. I am still working on them.

Feedback and bug fixes are welcome.

Regards
Stefan
