Subject: Getting HDD serial in kernel space
Date: Sat, 14 Nov 2009 14:34:54 +0300 [thread overview]
Message-ID: <4AFE95DE.3070308@gmail.com> (raw)
Hello.
I had a necessity to get HDD serial number in my kernel module.
In user space I can do it so:
fd = open( "/dev/sda", O_RDONLY|O_NONBLOCK );
ioctl( fd, HDIO_GET_IDENTITY, &id );
printf( "Serial: %s", id.serial_no );
How can I do it in kernel space (it is one hdd in machine, plugged with
SATA)?
