Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware.

Separate mse driver into a core driver and a bus attachments. Separate out the ISA and CBUS (called isa on pc98) attachments. Eliminate all PC98 ifdefs in the process (the driver in pc98/pc98/mse.c was a copy of the one in i386/isa/mse.c with PC98 ifdefs). Create a module for this driver.
I've tested this my PC-9821RaS40 with moused. I've not tested this on i386 because I have no InPort cards, or similar such things. NEC standardized on bus mice very early, long before ps/2 mice ports apeared, so all PC-98 machines supported by FreeBSD/pc98 have bus mice, I believe.

Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().

This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".
Initialize the d_maj and d_bmaj fields.
The d_reset field was not removed, although it is never used.
I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way.
Vinum and i4b not modified, patches emailed to respective authors.

Make all file-system (MFS, FFS, NFS, LFS, DEVFS) related option new-style.
This introduce an xxxFS_BOOT for each of the rootable filesystems. (Presently not required, but encouraged to allow a smooth move of option *FS to opt_dontuse.h later.)
LFS is temporarily disabled, and will be re-enabled tomorrow.

- Add support for the following mice to psm/moused/sysmouse:
MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll, Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII MieMouse, Logitech MouseMan+, FirstMouse+
- The `psm' driver is made to recognize various models of PS/2 mice and enable their extra features so that their additional buttons and wheel/roller are recognized. The name of the detected model will be printed at boot time.
- A set of new ioctl functions are added to the `psm', `mse' and `sysmouse' drivers so that the userland program (such as the X server) can query device information and change driver settings.
- The wheel/roller movement is handled as the `Z' axis movement by the mouse drivers and the moused daemon. The Z axis movement may be mapped to another axis movement or buttons.
- The mouse drivers support a new, standard mouse data format, MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement and up to 10 buttons.
/sys/i386/include/mouse.h - Added some fields to `mousestatus_t' to store Z axis movement and flag bits. - Added the field `model' to `mousehw_t' to store mouse model code. Defined model codes. - Extended `mousemode_t'. - Added new protocols and some constants for them. - Added new ioctl functions and structures. - Removed obsolete ioctl definitions.
/sys/i386/include/console.h - Added `dz' field to the structure `mouse_data' to pass Z axis movement to `syscons/sysmouse'. - Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON. Use button bits defined in `mouse.h' instead.
/sys/i386/isa/psm.c - Added a set of functions to detect various mice which have additional features (wheel and buttons) unavailable in the standard PS/2 mouse. - Refined existing ioctl functions and added new ones. Most important of all is MOUSE_SETLEVEL which manipulates the output level of the driver. While the output level remains zero, the output from the `psm' driver is in the standard PS/2 mouse format (three bytes long). When the level is set to one, the `psm' driver will send data in the extended format. At the level two the driver uses the format which is native to the connected mouse is used. (Meaning that the output from the device is passed to the caller as is, unmodified.) The `psm' driver will pass such extended data format as is to the caller if the output level is two, but emulates the standard format if the output level is zero. - Added kernel configuration flags to set initial resolution (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL). - Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION. Acceleration ratio is now specified by the kernel configuration flags stated above. Sync check logic is refined and now standard. The sync check can be turned off by the new kernel configuration flags PSM_CONFIG_NOCHECKSYNC (0x100). PSM_EMULATION has been of little use. - Summer clean up :-) Removed unused code and obsolete comments.
/sys/i386/isa/mse.c - Created mseioctl() to deal with ioctl functions MOUSE_XXXX. Most importantly, the MOUSE_SETLEVEL ioctl will change the output format from the 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Use constants defined in `mouse.h' rather than magic numbers.
/sys/i386/isa/syscons.c - Changed scioctl() to reflect the new `console.h' and some of the new ioctls defined in `mouse.h'. Most importantly, the MOUSE_SETLEVEL ioctl will change the `sysmouse' output format from the MouseSystems 5 byte format to the new, extended format so that the caller can take advantage of Z axis movement and additional buttons. - Added support for double/triple click actions of the left button and single click action of the right button in the virtual console. The left button double click will select a word under the mouse pointer. The triple click will select a line and the single click of the right button will extend the selected region to the current position of the mouse pointer. This will make the cut/paste support more compatible with xterm.
/sys/i386/isa/kbdio.h - Added PSM_INTELLI_ID.

the second set of changes in a move towards getting devices to be totally dynamic.
this is only the devices in i386/isa I'll do more tomorrow. they're completely masked by #ifdef JREMOD at this stage... the eventual aim is that every driver will do a SYSINIT at startup BEFORE the probes, which will effectively link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn) The ioconf lines generated by config will also end up in the device's own scope as well, so ioconf.c will eventually be gutted the SYSINIT call to the driver will include a phase where the driver links it's ioconf line into a chain of such. when this phase is done then the user can modify them with the boot: -c config menu if he wants, just like now.. config will put the config lines out in the .h file (e.g. in aha.h will be the addresses for the aha driver to look.) as I said this is a very small first step.. the aim of THIS set of edits is to not have to edit conf.c at all when adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made, all teh time still having a fully working kernel tree, but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as run-time loaded drivers, except they JUST HAPPEN to already be linked and present at startup.. the SYSINIT calls will be the equivalent of the "init" call made to a newly loaded driver in every respect.
For this edit, each of the files has the following code inserted into it:
obviously, tailored to suit.. ----------------------somewhere at the top: #ifdef JREMOD #include <sys/conf.h> #define CDEV_MAJOR 13 #define BDEV_MAJOR 4 static void sd_devsw_install(); #endif /*JREMOD */ ---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT #ifdef JREMOD sd_devsw_install(); #endif /*JREMOD*/ -----------------------at the bottom: #ifdef JREMOD struct bdevsw sd_bdevsw = { sdopen, sdclose, sdstrategy, sdioctl, /*4*/ sddump, sdsize, 0 };
struct cdevsw sd_cdevsw = { sdopen, sdclose, rawread, rawwrite, /*13*/ sdioctl, nostop, nullreset, nodevtotty,/* sd */ seltrue, nommap, sdstrategy };
static sd_devsw_installed = 0;
static void sd_devsw_install() { dev_t descript; if( ! sd_devsw_installed ) { descript = makedev(CDEV_MAJOR,0); cdevsw_add(&descript,&sd_cdevsw,NULL); #if defined(BDEV_MAJOR) descript = makedev(BDEV_MAJOR,0); bdevsw_add(&descript,&sd_bdevsw,NULL); #endif /*BDEV_MAJOR*/ sd_devsw_installed = 1; } } #endif /* JREMOD */

Finished device configuration database work for all ISA devices (except `ze') and all SCSI devices (except that it's not done quite the way I want). New information added includes:
- A text description of the device - A ``state''---unknown, unconfigured, idle, or busy - A generic parent device (with support in the m.i. code) - An interrupt mask type field (which will hopefully go away) so that . ``doconfig'' can be written
This requires a new version of the `lsdev' program as well (next commit).

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference.
This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following:
rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

This is my patched version of a busmouse driver originally by Rick Macklem (rick@snowhite.cis.uoguelph.ca). I am currently using it with a Microsoft InPort busmouse, under FreeBSD Epsilon. I hadn't planned on supporting it, but I have patched it a few times, and I guess this is now the de facto reference version, so send me any problems or improvements.
