We are trying to provide support for Emulated SMSC911X Ethernet controller.Current Qemu already had support for SMSC91X controller which looks near SMSC91X controller.
For providing support to SMSC911x we have done the following modifications related to kernel changes :
1. modified the versatile def config file to support SMSC911.x CONFIG_SMSC911x
2 modified core .c file to support /arc/arm/mach-versatile to support smsc911x.c
modified the structure static struct platform_device smc91x_device = {
.name = "smc91x",
.id = 0,
.num_resources = ARRAY_SIZE(smc91x_resources),
.resource = smc91x_resources,
};
with
static struct platform_device smc91x_device = {
.name = "smsc911x",
.id = 0,
.num_resources = ARRAY_SIZE(smc91x_resources),
.resource = smc91x_resources,
};
compiled our kernel with the above changes and the run qemu with the modfied kernel , but it fails with smsc911x_probe .
Can anyone please pointout whether we are following the right process ?
