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

|
* between system processes.
|
|
*
|
|
* 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 and responses
|
|
* 0x500 - 0x5FF Block device requests and 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 Input server messages
|
|
* 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.
