hello,
Thanks a lot for the reply.
A question which arises is, If the kernel calls the
probe routine (in case of PCI)for all the devices
attached to it during bus-enumeration, whats the point
of having the device entries in GENERIC?does the
bus-dependent code call the probe routine of the
device-driver,for only those devices which are
mentioned in GENERIC file.
I am writing a device driver for a memory mapped
ethernet device.Does it HAVE to be attached to a
bus?Its the only device I want to support(right
now).Is it not possible to hard-code the probe-attach
routine calls?
Can i attach it to nexus? OR Can I attach it to the
PCI bus (though its not a PCI device) through some
hack?
This is not a i386 port hence the ISA bus is absent.
Will i have to implement a pseudo-bus (write the
bus-dependent code)in order to attach my device?
Thank you,
Alok.
