Driver to Driver communication, with kobj?
Hi, I was wondering what the best way of doing driver to driver communication is. I'm trying to enqueue an ata-command from a completely different driver (nothing to do with storage / ata). I would just bluntly use the ata_controlcmd() function, but it would require for me to know the device_t of the drive I'm trying to access. I don't know which device_t it would be, nor do I know how to find it out. If this is a no-go... I really need some help with kobj, as I can't figure it out fully... How do you use a kobj "exported" method from another driver?

Driver to Driver Communication
Hi All, Could anybody help me to know how a driver to driver communication is done in FreeBSD ? My exact problem is something like this. In the current implementation of scsi_target mode driver, there is a associated userland application polling the target device and data is read from target device to user space and then written to a file. In stead, I want to do it in the scsi_target driver itself such that all I/O queues are redirected to a disk device. For this purpose, How can I interface with the scsi disk driver i.e. scsi_da.c from the scsi_target driver? Thanks & Regards, Jaya SMS using the Yahoo!
