totally dynamic. (the first was about 7 weeeks ago)
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 */
VoxWare v2.90 release notes
--------------------------
This version includes some hidden features which
are described in the file experimental.txt
Some of these features are not enabled by default. Look at
experimental.txt for more info.
I just decided to release this version with some
incompletely implemented features disabled since
there are some new features required by a popular
application. In addition there is also support
for the GUS MAX and the 16 bit sampling option of GUS.
The MSS/WSS support works now. At least with SG NX Pro 16.
********* IMPORTANT *****************************************
Linux 1.0 or later is required to by this driver version.
Don't distribute binaries which use /dev/sequencer and are
compiled with the soundcard.h of this version. They will
not work with version 2.x of the driver.
*************************************************************
You will need the snd-util-2.5.tar.gz and snd-data-0.1.tar.Z
packages to use this driver. They should be in the same
ftp site or BBS from where you got this driver. For
example at nic.funet.fi:pub/OS/Linux/*.
If you are looking for the installation instructions, please
look at linux/Readme.
Compatibility with the earlier versions
---------------------------------------
This version is backward compatible with the version 2.X. All programs
compiled with sys/soundcard.h of v2.X should work without problems.
PROGRAMS COMPILED WITH THE sys/soundcard.h OF THIS VERSION WILL NOT
WORK WITH v2.X DRIVER. BE CAREFUL WHEN DISTRIBUTING BINARIES COMPILED
FOR THIS VERSION.
