28d90c30ee Add the D_DISK flag to the cdevsw structs of various CD-ROM drivers. 1997-05-10 12:13:17 +00:00

5a9714de76 This mega-commit brings the following:
. It makes cd9660 root f/s working again.
. It makes CD9660 a new-style option.
. It adds support to mount an ISO9660 multi-session CD-ROM as the root
  filesystem (the last session actually, but that's what is expected
  behaviour).

Sigh.  The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work.  Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-(  I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.

While doing this, i noticed the following bogosities in existing CD-ROM
drivers:

wcd:	This driver is likely to be totally bogus when someone tries
	two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
	commands with requesting MSF format, since it apparently
	operates on an internal table.

scd:	This driver apparently returns just a single TOC entry only for
	the CDIOREADTOCENTRYS command.

I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver.  I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver.  When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.

20925249e7 Fixed the type of timeout functions and removed casts that hid the
type mismatches.  mcd and scd were/are particularly bogus.  They
used a general purpose function taking 2 args for the timeout
function and fudged varargs stuff to supply the second arg for the
timeout case.  This broke `cc -mrtd'.  Bounce through a timeout
function instead.  The timeout arg still gets bogusly cast from
int to `void *' and back.

fce002fdef Don't include <sys/ioctl.h> in the kernel. Stage 1: don't include
it when it is not used.  In most cases, the reasons for including it
went away when the special ioctl headers became self-sufficient.

cba8a5ddd3 Make a "DWIM" function for adding [bc]devsw entries for bdev drivers.
Saves about 280 butes of source per driver, 56 bytes in object size
and another 56 bytes moves from data to bss.

No functional change intended nor expected.

GENERIC should be about one k smaller now :-)

9b2b0822b7 Removed unused #includes of <i386/isa/icu.h> and <i386/isa/icu.h>. icu.h
is only used by the icu support modules and by a few drivers that know
too much about the icu (most only use it to convert `n' to `IRQn').  isa.h
is only used by ioconf.c and by a few drivers that know too much about
isa addresses (a few have to, because config is deficient).

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.. :)

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)

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.

0fb7352341 Bring in the new non-GPL'd driver from Mikael Hybsch. This version is
NOT derived from the Linux code and is thus not GPL'd.  It is the author's
express wish that the GPL copyrighted version be removed and this BSD copyright
version take its place.  Considering our own stance on this, I'm certainly
not going to argue!  [Note to NetBSD folks:  You're free to grab it now :-)]
