dnl
dnl Common device definitions.
dnl
dnl This file contains the MI device definitions (as well as some MD
dnl definitions not cleaned up yet...)
dnl
dnl Diversions:  (upon termination, concatenated output queues)
dnl
dnl 0 - very top
dnl 1 - descriptions of devices
dnl 2 - init of script, function definitions, etc
dnl 3 - beginning of global recursive R() function
dnl 7 - body of MAKEDEV, device creations, etc
dnl 9 - end
dnl
dnl Diversions 2, 3 and 7 are not filled when generating the manual page.
dnl
dnl HOW TO ADD A DEVICE:
dnl
dnl In this file, you must use at least two macros:
dnl
dnl  Use '__devitem(uniqueid, name-pattern, description)' to create an entry
dnl  in the description at the top of the generated MAKEDEV file:
dnl
dnl    __devitem(sca, sca*, Sugar Generic device)dnl
dnl    __devitem(cry, crypto, hardware crypto access driver)dnl
dnl
dnl  This is ultimately shown as:
dnl
dnl    #  sca*   Sugar Generic device
dnl    #  crypto hardware crypto access driver
dnl
dnl  Use '_mkdev(uniqueid, shell-pattern, {-shell-script-})dnl' to create
dnl  a shell script fragment used to 'create' the device (be sure to match
dnl  the uniqueid from above):
dnl
dnl    _mkdev(sca, sca*, {-M sca$U c major_sca_c $U
dnl           M rsca$U b major_sca_b Add($U, 128)-})dnl
dnl    _mkdev(cry, crypto, {-M crypto c major_cry_c 0-})dnl
dnl
dnl  This is ultimately expanded into:
dnl
dnl    sca*)
dnl           M sca$U c 24 $U
dnl           M sca$U b 42 $(($U+128))
dnl           ;;
dnl
dnl    crypto)
dnl           M crypto c 47 0
dnl           ;;
dnl
dnl In the MAKEDEV.md file, add a '_DEV(uniqueid, charmajor, blockmajor)'
dnl entry:
dnl
dnl   _DEV(sca, 24, 42)
dnl   _DEV(cry, 47)
dnl
dnl Final step is to use the 'target/twrget' macros to have the 'all)' target
dnl generate one or more device(s).  Usage of 'target/twrget' is:
dnl      target(target_name, device_name [, append_string ] .. )
dnl      twrget(target_name, uniqueid, device_name, [, append_string ] .. )
dnl
dnl        target_name   a unique name that later is used as an argument to
dnl                      'show_target()' (which expands all devices for a
dnl                      given 'target_name').
dnl        uniqueid      same as 'uniqueid' above
dnl        device_name   string representing the device to be mknod'ed
dnl        append_string for each append_string, `device_name' is prepended
dnl
dnl Note: 'target(a,b,c)' is equivalent to 'twrget(a,b,b,c)'
dnl
dnl
dnl For a short example:
dnl
dnl   target(all, std)dnl
dnl   target(all, sca, 0, 1, 2, 3)dnl
dnl   twrget(all, cry, crypto)dnl
dnl
dnl would expand to:
dnl
dnl   all)
dnl        R std sca0 sca1 sca2 sca3 crypto
dnl        ;;
dnl
dnl presuming '_DEV(sca, ?, ?)' and '_DEV(std)' were in the MAKEDEV.md file.
dnl
dnl
dnl Everything is 'automatically' added to 'MAKEDEV' based on whether or
dnl not the '_DEV()' entry has a corresponding _mkdev() and __devitem()
dnl entry in MAKEDEV.mi (this file).
dnl
dnl Note: be very wary of adding whitespace, carriage returns, or not
dnl finishing a macro with ')dnl' .. otherwise, extra blank lines show up
dnl in the output.
dnl
dnl TODO:
dnl
dnl make a 'disktgt' macro that automatically does:
dnl disktgt(rd, {-rd-})
dnl
dnl	target(all,rd,0)
dnl	target(ramd,rd,0)
dnl	disk_q(rd)
dnl	__devitem(rd, {-rd*-}, {-rd-})dnl
dnl
dnl  Note: not all devices are generated in 'all)' below. MAKEDEV.md contains
dnl        its own extra list.
