f332b8a1d5 Replaced nxdump by nodump (if the dump function gets called, then the
device must be configured, so ENXIO is a bogus errno).

87f6c6625d Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)

7198bf4725 If you're going to mechanically replicate something in 50 files
it's best to not have a (compiles cleanly) typo in it! (sigh)

53ac6efbd8 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)
1995-11-29 10:49:16 +00:00

7146c13e43 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 */

4fda91c705 Moved prototypes for devswitch functions from conf.c and driver sources
to <machine/conf.h>.  conf.h was mechanically generated by
`grep ^d_ conf.c >conf.h'.  This accounts for part of its ugliness.  The
prototypes should be moved back to the driver sources when the functions
are staticalized.

6c0081e92b Add a class field to devconf and mst drivers.
For those where it was easy, drivers were also fixed to call
dev_attach() during probe rather than attach (in keeping with the
new design articulated in a mail message five months ago).  For
a few that were really easy, correct state tracking was added as well.
The `fd' driver was fixed to correctly fill in the description.
The CPU identify code was fixed to attach a `cpu' device.  The code
was also massively reordered to fill in cpu_model with somethingremotely
resembling what identifycpu() prints out.  A few bytes saved by using
%b to format the features list rather than lots of ifs.

2f86936a07 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).

c4ff2eb1dd Newly implemented ioctls list:
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.

CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).

All routines now detects media change correctly.

DELAY_GETREPLAY increased for long time access from first track
to last.

mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.

mcd_doread() now uses real status (old code uses obsoleted soft copy of it).

clear XBSY on error in mcd_doread()

mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()

optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.

call getdisklabel() _after_ mcdsize() for proper sizes

mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.

Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.

Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.

CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)

Read junk code added after read block code in doread (from DOS driver)

mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.

mcd_playtracks() code fixed to proper check valid track range.

New binary read modes implemented (from DOS driver).

f540b1065a 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

1) check va before clearing the page clean flag. Not doing so was
	causing the vnode pager error 5 messages when paging from
	NFS. (pmap.c)
2) put back interrupt protection in idle_loop. Bruce didn't think
	it was necessary, John insists that it is (and I agree). (swtch.s)
3) various improvements to the clustering code (vm_machdep.c). It's
	now enabled/used by default.
4) bad disk blocks are now handled properly when doing clustered IOs.
	(wd.c, vm_machdep.c)
5) bogus bad block handling fixed in wd.c.

/dev/mcd0a instead of /dev/mcd0d. This is more conforming to the /dev/cd0a
for the SCSI cdrom drives. It breaks the convention d the whole drive.
But the question is, do we really need partitions on cdrom drives ?
