Hi All,
I am trying to write a linux kernel module which can send/receive
ATA SMART cmds to a HDD. The kernel module will take a set of actions based
on the responses it receives from the HDD. I went through the ATA smart
cmds spec and the "smartctl" user space code which sends the ATA cmds from
user space via SG_IO ioctl cmd. I am not able to figure out how to open
/dev/sda from kernel and achieve similar functionalities line "smartctl"
tool from a kernel module.
1.
Can someone point me to any sample code which tries to send ATA smart
cmds from a kernel module instead of user space via ioctl?
2.
Seems like I need to use some exported API from SG driver or libata. is
this the right direction?
3.
Please feel free to suggest how can I achieve this.
Thanks, Sid
