There is important information about booting non-ack images in docs/UPDATING. ack/aout-format images can't be built any more, and booting clang/ELF-format ones is a little different. Updating to the new boot monitor is recommended. Changes in this commit: . drop boot monitor -> allowing dropping ack support . facility to copy ELF boot files to /boot so that old boot monitor can still boot fairly easily, see UPDATING . no more ack-format libraries -> single-case libraries . some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases . drop several ack toolchain commands, but not all support commands (e.g. aal is gone but acksize is not yet). . a few libc files moved to netbsd libc dir . new /bin/date as minix date used code in libc/ . test compile fix . harmonize includes . /usr/lib is no longer special: without ack, /usr/lib plays no kind of special bootstrapping role any more and bootstrapping is done exclusively through packages, so releases depend even less on the state of the machine making them now. . rename nbsd_lib* to lib* . reduce mtree

/* 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 Input
