Hi all, I am using ioctl() to send a vendor unique command to a disk drive via the libata driver stack. The command is a security erase command and it takes several minutes for the command to complete. During this time, my driver is timing out. Now, I don't really have a problem with the driver timing out. What I'm wondering is whether there's a way to make the ioctl() timeout faster so that my program can continue execution. I see that in the sg_io_hdr_t struct passed to ioctl() there is a timeout value specified in ms. I've entered values between 5 and 500 but it is taking 90-100 seconds for the command to return and for my program to continue. Does anyone have a suggestion on how to make this ioctl() timeout faster and return to executing my program? Thanks! -Russell Sloan
I would ask that directly on the "Linux-ide" <linux-ide@xxxxxxxxxxxxxxx> mailing list. FYI: I doubt you would use an ioctl on newer kernels, so you might want to start by asking if there is a better way to do it, etc. Specifically, the libata team is trying to get standard support in the kernel for bios password management etc. that is needed when you put a laptop into powersave mode, etc. Seems like that same infrastructure you will need for a secure erase.
