I am working on the host interface device driver
for IMA.I am writing a Linux device driver for this.
The only functionalites required by the driver is that it should
write raw data to the memory in the ATMiser(a chip) and also read data from the
same.
So what sort of a device driver should i go for?
What I feel is that I can't write it as a network device driver.
In Linux , all the i/f for n/w device driver goes thru
tcp/ip layers and finally to the card. i want to write
raw data to the card without the TCP/IP headers for testing
(Otherwise that would have been the ideal option since this
is a n/w card).
The device driver is used for testing the card.
So what sort of a driver should I go for ?
Character or Block?
My doubt is that if I write it as a char driver,will the speed of
the data tranfer be affected?(ie will it be really bad?)
Thanx in advance,
with regards,
prakash.
