The block driver protocol and libblockdriver's bdr_ioctl hook are changed, as well as the users of this hook. Other parts of the system are expected to change accordingly eventually, since the ioctl(2) prototype has been aligned with NetBSD's. Change-Id: Ide46245b22cfa89ed267a38088fb0ab7696eba92

/* This file defines constants for use in message communication (mostly)

|
|
* A number of protocol message request and response types are defined. For
|
|
* debugging purposes, each protocol is assigned its own unique number range.
|
|
* The following such message type ranges have been allocated:
|
|
*
|
|
* 1 - 0xFF POSIX requests (see callnr.h)
|
|
* 0x200 - 0x2FF Data link layer requests and responses
|
|
* 0x300 - 0x3FF Bus controller requests and responses
|
|
* 0x400 - 0x4FF Character device requests
|
|
* 0x500 - 0x5FF Character device responses
|
|
* 0x600 - 0x6FF Kernel calls to SYSTEM task
|
|
* 0x700 - 0x7FF Reincarnation Server (RS) requests
|
|
* 0x800 - 0x8FF Data Store (DS) requests
|
|
* 0x900 - 0x9FF Requests from PM to VFS, and responses
|
|
* 0xA00 - 0xAFF Requests from VFS to file systems (see vfsif.h)
|
|
* 0xB00 - 0xBFF Requests from VM to VFS
|
|
* 0xC00 - 0xCFF Virtual Memory (VM) requests
|
|
* 0xD00 - 0xDFF IPC server requests
|
|
* 0xE00 - 0xEFF Common system messages (e.g. system signals)
|
|
* 0xF00 - 0xFFF Scheduling messages
|
|
* 0x1000 - 0x10FF Notify messages
|
|
* 0x1100 - 0x11FF USB
|
|
* 0x1200 - 0x12FF Devman
|
|
* 0x1300 - 0x13FF TTY Requests
|
|
* 0x1400 - 0x14FF VFS-FS transaction IDs
|
|
* 0x1500 - 0x15FF Block device requests and responses
|
|
* 0x1600 - 0x16FF VirtualBox (VBOX) requests (see vboxif.h)
|
|
* 0x1700 - 0x17FF Real Time Clock requests and responses
|
|
*
|
|
* Zero and negative values are widely used for OK and error responses.
