If you're going to mechanically replicate something in 50 files it's best to not have a (compiles cleanly) typo in it! (sigh)

OK, that's it.. That's EVERY SINGLE driver that has an entry in conf.c.. my next trick will be to define cdevsw[] and bdevsw[] as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry that comes in very early.. and asks teh driver to add it's own entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT stuff and some usually wrong but token DEVFS entries to all these devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside? seems we don't actually have a 'ataopen() etc...
If you want to add a new device in conf.c please make sure I know so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD) (and #ifdef DEVFS in parts)

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 */

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

* Applied fixes from Bruce Evans to fix COW bugs, >1MB kernel loading, profiling, and various protection checks that cause security holes and system crashes. * Changed min/max/bcmp/ffs/strlen to be static inline functions - included from cpufunc.h in via systm.h. This change improves performance in many parts of the kernel - up to 5% in the networking layer alone. Note that this requires systm.h to be included in any file that uses these functions otherwise it won't be able to find them during the load. * Fixed incorrect call to splx() in if_is.c * Fixed bogus variable assignment to splx() in if_ed.c

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.
