1 | Ioctl Numbers |
| 2 | 19 October 1999 | |
| 3 | Michael Elizabeth Chastain | |
| 4 | <mec@shout.net> | |
| 5 | ||
| 6 | If you are adding new ioctl's to the kernel, you should use the _IO | |
| 7 | macros defined in <linux/ioctl.h>: | |
| 8 | ||
| 9 | _IO an ioctl with no parameters | |
| 10 | _IOW an ioctl with write parameters (copy_from_user) | |
| 11 | _IOR an ioctl with read parameters (copy_to_user) | |
| 12 | _IOWR an ioctl with both write and read parameters. | |
| 13 | ||
| 14 | 'Write' and 'read' are from the user's point of view, just like the | |
| 15 | system calls 'write' and 'read'. For example, a SET_FOO ioctl would | |
| 16 | be _IOW, although the kernel would actually read data from user space; | |
| 17 | a GET_FOO ioctl would be _IOR, although the kernel would actually write | |
| 18 | data to user space. | |
| 19 | ||
| 20 | The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter | |
| 21 | or number from the table below. Because of the large number of drivers, | |
| 22 | many drivers share a partial letter with other drivers. | |
| 23 | ||
| 24 | If you are writing a driver for a new device and need a letter, pick an | |
| 25 | unused block with enough room for expansion: 32 to 256 ioctl commands. | |
| 26 | You can register the block by patching this file and submitting the | |
| 27 | patch to Linus Torvalds. Or you can e-mail me at <mec@shout.net> and | |
| 28 | I'll register one for you. | |
| 29 | ||
| 30 | The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number | |
| 31 | to distinguish ioctls from each other. The third argument to _IOW, | |
| 32 | _IOR, or _IOWR is the type of the data going into the kernel or coming | |
| 33 | out of the kernel (e.g. 'int' or 'struct foo'). NOTE! Do NOT use | |
| 34 | sizeof(arg) as the third argument as this results in your ioctl thinking | |
| 35 | it passes an argument of type size_t. | |
| 36 | ||
| 37 | Some devices use their major number as the identifier; this is OK, as | |
| 38 | long as it is unique. Some devices are irregular and don't follow any | |
| 39 | convention at all. | |
| 40 | ||
| 41 | Following this convention is good because: | |
| 42 | ||
| 43 | (1) Keeping the ioctl's globally unique helps error checking: | |
| 44 | if a program calls an ioctl on the wrong device, it will get an | |
| 45 | error rather than some unexpected behaviour. | |
| 46 | ||
| 47 | (2) The 'strace' build procedure automatically finds ioctl numbers | |
| 48 | defined with _IO, _IOW, _IOR, or _IOWR. | |
| 49 | ||
| 50 | (3) 'strace' can decode numbers back into useful names when the | |
| 51 | numbers are unique. | |
| 52 | ||
| 53 | (4) People looking for ioctls can grep for them more easily when | |
| 54 | this convention is used to define the ioctl numbers. | |
| 55 | ||
| 56 | (5) When following the convention, the driver code can use generic | |
| 57 | code to copy the parameters between user and kernel space. | |

59 | This table lists ioctls visible from user land for Linux/x86. It contains |
| 60 | most drivers up to 2.6.31, but I know I am missing some. There has been | |
| 61 | no attempt to list non-X86 architectures or ioctls from drivers/staging/. | |
