Best way to exercise NVME ioctls

[Prasad Joshi]

Hi All,

I am doing experiments with nvme linux driver. I would like to write
some sample programs which uses nvme ioctls. Specifically I wanted to
invoke identify command to start with. nvme.h header file contains two
structures "nvme_admin_cmd" and "nvme_identify", both seem to be
identical.

Would there be any problem if I use any one of them for calling nvme IOCTL?
What will be the best and ideal way?

Thanks and Warm Regards,
Prasad

I put some basic user programs up on another repository at

http://git.infradead.org/users/kbusch/nvme-user.git

It is very basic stuff; the programs there just run an nvme command
through the ioctl and print the data in more-or-less human readable
form.

Thanks a lot for your reply. This is good enough to get us started.

Thanks and Regards,
