1 /* This file defines constants for use in message communication (mostly)
2 * between system processes.
3 *
4 * A number of protocol message request and response types are defined. For
5 * debugging purposes, each protocol is assigned its own unique number range.
6 * The following such message type ranges have been allocated:
7 *
8 * 1 - 0xFF POSIX requests (see callnr.h)
9 * 0x200 - 0x2FF Data link layer requests and responses
10 * 0x300 - 0x3FF Bus controller requests and responses
11 * 0x400 - 0x4FF Character device requests
12 * 0x500 - 0x5FF Character device responses
13 * 0x600 - 0x6FF Kernel calls to SYSTEM task
14 * 0x700 - 0x7FF Reincarnation Server (RS) requests
15 * 0x800 - 0x8FF Data Store (DS) requests
16 * 0x900 - 0x9FF Requests from PM to VFS, and responses
17 * 0xA00 - 0xAFF Requests from VFS to file systems (see vfsif.h)
18 * 0xB00 - 0xBFF Requests from VM to VFS
19 * 0xC00 - 0xCFF Virtual Memory (VM) requests
20 * 0xD00 - 0xDFF IPC server requests
21 * 0xE00 - 0xEFF Common system messages (e.g. system signals)
22 * 0xF00 - 0xFFF Scheduling messages
23 * 0x1000 - 0x10FF Notify messages
24 * 0x1100 - 0x11FF USB
25 * 0x1200 - 0x12FF Devman
26 * 0x1300 - 0x13FF TTY Input
27 * 0x1400 - 0x14FF VFS-FS transaction IDs
28 * 0x1500 - 0x15FF Block device requests and responses
29 * 0x1600 - 0x16FF VirtualBox (VBOX) requests (see vboxif.h)
30 *
31 * Zero and negative values are widely used for OK and error responses.
