uioc Struct Reference

#include <megaraid_ioctl.h>

List of all members.

Detailed Description

struct uioc_t - the common ioctl packet structure

: Must be "$$_EXTD_IOCTL_$$" : Type of the mail box (MB_LEGACY or MB_HPE) : Type of the issuing application (existing or new) : Opcode of the command : Adapter number : Pointer to buffer - can point to mbox or plain data buffer : xferlen for DCMD and non mailbox commands : Direction of the data transfer : Status from the driver : reserved bytes for future expansion

: user data transfer address is saved in this : length of the data buffer sent by user app : user passthru address is saves in this (null if DCMD) : kernel address passthru (allocated per kioc) : physicall address of : for kioc free pool list maintenance : call back routine for llds to call when kioc is completed : dma pool buffer attached to kioc for data transfer : physical address of the dma pool buffer : index of the dma pool that is taken from : indicates if buffer needs to be freed after kioc completes

Note : All LSI drivers understand only this packet. Any other : format sent by applications would be converted to this.
