Hi Sam,

how can i send ioctl from application to miniport driver
– You can use IOCTL_SCSI_MINIPORT to send a command to the Mniport
Need to fill in the paramenters of the SRB_IO_CONTROL Structure and issue the command using DeviceIoControl.

But, the miniport driver you are using should support SRB_FUNCTION_IO_CONTROL Function Implemented.

Hi Sam,
If your requirement is just to send an ATA command directly to your miniport driver you can use IOCTL_ATA_PASS_THROUGH_DIRECT Interface provided by Microsoft.
You need to fill the ATA_PASS_THROUGH_DIRECT Structure parameters and use Pass through Interface to send the command directly to the device.

Narendra.

Hi sam,

I understand your requirement,
Are you implementing the ata miniport driver or you are using the Microsoft’s default ATA miniport driver?

Thanks,
Narendra.

Consider creating a an upper filter driver that handles the IOCTL and
turns it into IRP_MJ_PNP/IRP_MN_READ_CONFIG to pass down the stack.

Hi Sam,

you need to implement the Upper Class Filter Driver that handles your IOCTL and issues a IRP with IRP_MJ_PNP/IRP_MN_READ_CONFIG to the port.

You Can go through the follwoing link.
