netchild's mega-patch to isolate compiler dependencies into a central place.
This moves the dependency on GCC's and other compiler's features into the central sys/cdefs.h file, while the individual source files can then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.
By now, GCC and ICC (the Intel compiler) have been actively tested on IA32 platforms by netchild. Extension to other compilers is supposed to be possible, of course.

Boot away another stackgap (one of the lest ones in linuxlator/i386) by providing special version of CDIOCREADSUBCHANNEL ioctl(), which assumes that result has to be placed into kernel space not user space. In the long run more generic solution has to be designed WRT emulating various ioctl()s that operate on userspace buffers, but right now there is only one such ioctl() is emulated, so that it makes little sense.

Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set.
B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.

There is no such thing any more as "struct bdevsw".
There is only cdevsw (which should be renamed in a later edit to deventry or something). cdevsw contains the union of what were in both bdevsw an cdevsw entries. The bdevsw[] table stiff exists and is a second pointer to the cdevsw entry of the device. it's major is in d_bmaj rather than d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).
rawread()/rawwrite() went away as part of this though it's not strictly the same patch, just that it involves all the same lines in the drivers.
cdroms no longer have write() entries (they did have rawwrite (?)). tapes no longer have support for bdev operations.

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.

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.

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

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.. :)

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 */

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.

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.

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 :-)] Submitted by: Mikael Hybsch <micke@dynas.se>
