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.. :)

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

Removed $Log$ section and patch kit headers. And here is the full message for Bruces changes: >From: bde@kralizec.zeta.org.au (Bruce Evans) >Subject: fixes for fd driver I think I've fixed some bugs in the 0.2.4 fd driver. 1. The main cause of hangs was that there was no timeout for seeks. So attempting i/o with no floppy in the drive hung iff a seek was required. 2. Opens of unattached drives were allowed. The kernel usually paniced soon after due to a bad pointer. 3. Some timeout functions ran at splclock() instead of splbio(). This may not have mattered. 4. The state machine was left in a funny state after a timeout. 5. Some function headers were new-style. 6. I picked up some code posted the other day to implement label ioctls. Now `disklabel fd0' works. See a comment for how to modify conf.c.

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

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

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.. :)

Make everything compile with -Wtraditional. Make it easier to distribute a binary link-kit. Make all non-optional options (pagers, procfs) standard, and update LINT to reflect new symtab requirements. NB: -Wtraditional will henceforth be forgotten. This editing pass was primarily intended to detect any constructions where the old code might have been relying on traditional C semantics or syntax. These were all fixed, and the result of fixing some of them means that -Wall is now a realistic possibility within a few weeks.

Make everything compile with -Wtraditional. Make it easier to distribute a binary link-kit. Make all non-optional options (pagers, procfs) standard, and update LINT to reflect new symtab requirements. NB: -Wtraditional will henceforth be forgotten. This editing pass was primarily intended to detect any constructions where the old code might have been relying on traditional C semantics or syntax. These were all fixed, and the result of fixing some of them means that -Wall is now a realistic possibility within a few weeks.

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

Allocate DMA bounce buffers only when requested by drivers. Only the fd and wt drivers need bounce buffers, so this normally saves 32K-1K of kernel memory. Keep track of which DMA channels are busy. isa_dmadone() must now be called when DMA has finished or been aborted. Panic for unallocated and too-small (required) bounce buffers. fd.c: There will be new warnings about isa_dmadone() not being called after DMA has been aborted. sound/dmabuf.c: isa_dmadone() needs more parameters than are available, so temporarily use a new interface isa_dmadone_nobounce() to avoid having to worry about panics for fake parameters.

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

New features: . ioctl command for setting the drive type (density etc.); restricted to the super-user . ioctl for getting/seting `drive options'; currently only option is FDOPT_NORETRY: inhibit the usual retries; used when verifying a newly formatted track Fixes: . function prototypes . made all internal functions `static' . cleaned up & corrected .h files . restructured, to make the chaotic function sequence more rational . compiled with -Wall, and cleared all warnings . introduced a mirror for the (write-only) `digital output register', to avoid the current kludge . device probing completed by seeking/recalibrating, and looking for track 0 being found . holding the controller down in reset state while it is idle (and thus saving allot of headaches) . make requests fail that are not a multiple of the (physical) sector size . removed the fixed physical sector size (512 bytes), allowing for any size the controller could handle (128/256/512/1024 bytes) . replaced some silly messages . fixed the TRACE* macro usage, debugging reports should be complete now again (debugging output is HUGE! though) . removed fd_timeout for SEEK command; seeks are always reported by the controller to succeed, since the `success' only refers to the controller's idea of success - there is no hardware line to tell about the seek end (other than the `track 0' line) . catch SENSEI's that report about a `terminated due to READY changed' status - could happen after a controller reset . converted ``hz / <something>'' divide operations to divisors that are powers of two, so gcc can optimize them into shifts . write/format operations are checked against a write-protected medium now *prior* starting the operation . error reports of `invalid command' and `wrong cylinder' will cause shortcuts in the retrier() now . fixed a bug in the retrier() causing bogus block numbers to be reported . fdformat() does care for errors now Known Bugs: . no attempts have been made (yet) to improve the performance . sometimes, bogus ``seek/recalib failed'' messages are logged; this is still a bug in the driver, but it's not harmful since it's usually caught by the retrier() Reviewed by: Submitted by: Obtained from:

No more partition bits in floppy minor. Now minor looks like UU DDDDDD, UU - unit, DDDDDD - density. If density == 0, CMOS-detect format assumed. Fix attach code for correct work with unknown CMOS floppy types. Trick diskerr to handle new minor. 1.722M floppy in 1.44M drive popular format added.

Also major cleanup in the low-level structure, there are now functions performing error-checks for the FDC I/O. Submitted by: (mostly) Peter Dufault <dufault@FreeBSD.org>

* XXX
Checking for timeout at several critical calls to ``out_fdc()'' now, so i hope i've finally removed all the occasions where the driver got stuck when there's no floppy in the drive. Also attemmpting to omit the error mesage for ``recalib failed'' for the first time, since people tend to be confused about this.

* special case: since we have just woken up the FDC

* be accepted, and do not test for a timeout

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

Finally implement support for the `lsdev' program. The controller is now marked busy as long as it's being in non-reset state, and the drives are busy as long as at least one instance is open. Also reformat everything to fit into 80 columns again. Changed my mind wrt. error reporting for a write-protected drive and an open() with write intent; ENXIO has been too weird, now return EIO. Some portions of the code need to be rewritten to use tprintf() instead of simple printf()'s, so the messages will also appear on the session terminal, however.

Fixed (nonexistent) initialization of bp->b_pblkno. disksort() for floppies must have been random in 2.x since we reintroduced sorting on b_pblkno on 1995/03/18. Drivers still initialize b_cylin/b_resid although this is no longer used. Removed unused, wrong function fdsize(). (Returning 0 means that the device exists and has size 0, not that the device doesn't exist. swaponvp() allows for size 0 by stupidly calling the d_psize function twice if the size isn't 0. setdumpdev() doesn't allow for it.) Continued removing /* ARGSUSED */ from drivers.

Back out Joerg's latest commit. Sorry, Joerg, but this breaks the install floppies now. I'm not sure why, but things hang when it gets to the `changing root to fd0c' part. Without your latest commit, everything works fine. Maybe you can figure out what you broke after ALPHA! :)

Peter's work to work around one of the most annoying bugs in the floppy driver (or in the hardware?). It turned out to be caused by spurious interrupts, right after an FDC reset. Also major cleanup in the low-level structure, there are now functions performing error-checks for the FDC I/O. Submitted by: (mostly) Peter Dufault <dufault@FreeBSD.org>

Back out Joerg's latest commit. Sorry, Joerg, but this breaks the install floppies now. I'm not sure why, but things hang when it gets to the `changing root to fd0c' part. Without your latest commit, everything works fine. Maybe you can figure out what you broke after ALPHA! :)

Checking for timeout at several critical calls to ``out_fdc()'' now, so i hope i've finally removed all the occasions where the driver got stuck when there's no floppy in the drive. Also attemmpting to omit the error mesage for ``recalib failed'' for the first time, since people tend to be confused about this.

* This might be a "ready changed" interrupt,
* which cannot really happen since the
* RDY pin is hardwired to + 5 volts. This
* generally indicates a "bouncing" intr
* line, so do one of the following:
*
* When running on an enhanced FDC that is
* known to not go stuck after responding
* with INVALID, fetch all interrupt states
* until seeing either an INVALID or a
* real interrupt condition.
*
* When running on a dumb old NE765, give
* up immediately. The controller will
* provide up to four dummy RC interrupt
* conditions right after reset (for the
* corresponding four drives), so this is
* our only chance to get notice that it
* was not the FDC that caused the interrupt.

Peter's work to work around one of the most annoying bugs in the floppy driver (or in the hardware?). It turned out to be caused by spurious interrupts, right after an FDC reset. Also major cleanup in the low-level structure, there are now functions performing error-checks for the FDC I/O. Submitted by: (mostly) Peter Dufault <dufault@FreeBSD.org>

Fix the broken EOF handling in the floppy driver. The most obvious appearance of this bug was the malfunctioning -M option in GNU tar (it worked only by explicitly specifying -L). Reviewed by: bde, and partially corrected accoring to his comments Candidate for 2.2, IMHO even for 2.1.6.

Make everything compile with -Wtraditional. Make it easier to distribute a binary link-kit. Make all non-optional options (pagers, procfs) standard, and update LINT to reflect new symtab requirements. NB: -Wtraditional will henceforth be forgotten. This editing pass was primarily intended to detect any constructions where the old code might have been relying on traditional C semantics or syntax. These were all fixed, and the result of fixing some of them means that -Wall is now a realistic possibility within a few weeks.

From: bde@kralizec.zeta.org.au (Bruce Evans) Date: Thu, 16 Sep 93 22:56:01 +1000 The fd driver reported the wrong cylinder/head/sector numbers after an error (ST3 is only valid after a sense-drive command), and didn't report fs block numbers (diskerr was not used). There was an old problem with writes to block fd devices. Try this: 1. write protect floppy in fd0. 2. tar cf /dev/fd0a /dev/null. Repeat a few times. Later writes tend to terminate earlier. 3. un-write protect floppy. 4. repeat step 2. The writes tend to return 0, 2048, 4096, ... and then succeed. This was caused by a bug in vfs__bios.c. (The bug is fixed in NetBSD's vfs_bio.c.) fd.c sets bp->b_resid to nonzero after an error. vfs__bios.c was not initializing bp->b_resid. This causes some writes to terminate early (e.g., writes to block devices; see spec_write()). Related funnies: 1. Nothing tries to write the residual bytes. 2. The wd driver sets bp->b_resid to 0 after an error, so there's no way anything else could write the residual bytes. 3. I use the block fd device for tar because the raw device seemed to have more bugs long ago, and because it ought to be able to handle buffering more transparently (I don't want to have to know the device size). But spec_write() always uses the size BLKDEV_IOSIZE == 2048 which is too small. For disks it should use the size of one track (rounded down to meet the next track boundary or the i/o size). Here it would help if the DIOCGPART ioctl worked. But DIOCGPART is not implemented for floppies, and the disk size is ignored except for partitions of type FS_BSDFFS. Bruce

Later writes tend to terminate earlier. 3. un-write protect floppy. 4. repeat step 2. The writes tend to return 0, 2048, 4096, ... and then succeed. This was caused by a bug in vfs__bios.c. (The bug is fixed in NetBSD's vfs_bio.c.) fd.c sets bp->b_resid to nonzero after an error. vfs__bios.c was not initializing bp->b_resid. This causes some writes to terminate early (e.g., writes to block devices; see spec_write()). Related funnies: 1. Nothing tries to write the residual bytes. 2. The wd driver sets bp->b_resid to 0 after an error, so there's no way anything else could write the residual bytes. 3. I use the block fd device for tar because the raw device seemed to have more bugs long ago, and because it ought to be able to handle buffering more transparently (I don't want to have to know the device size). But spec_write() always uses the size BLKDEV_IOSIZE == 2048 which is too small. For disks it should use the size of one track (rounded down to meet the next track boundary or the i/o size). Here it would help if the DIOCGPART ioctl worked. But DIOCGPART is not implemented for floppies, and the disk size is ignored except for partitions of type FS_BSDFFS. Bruce

Nothing much is going to start work on the next item. However, it is pointless to continue processing the queue for the same unready drive.

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 :-)

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.. :)

Bruce's multifarious patches for the floppy driver (not well tested, but since what we have is crap as it is, it can't do much worse!).

Updated driver to the 1.1.5 version: date: 1994/05/22 12:35:38; author: joerg; state: Exp; lines: +6 -6 First round of floppy changes. Try making `fd' more robust. New features: . ioctl command for setting the drive type (density etc.); restricted to the super-user . ioctl for getting/seting `drive options'; currently only option is FDOPT_NORETRY: inhibit the usual retries; used when verifying a newly formatted track Fixes: . function prototypes . made all internal functions `static' . cleaned up & corrected .h files . restructured, to make the chaotic function sequence more rational . compiled with -Wall, and cleared all warnings . introduced a mirror for the (write-only) `digital output register', to avoid the current kludge . device probing completed by seeking/recalibrating, and looking for track 0 being found . holding the controller down in reset state while it is idle (and thus saving allot of headaches) . make requests fail that are not a multiple of the (physical) sector size . removed the fixed physical sector size (512 bytes), allowing for any size the controller could handle (128/256/512/1024 bytes) . replaced some silly messages . fixed the TRACE* macro usage, debugging reports should be complete now again (debugging output is HUGE! though) . removed fd_timeout for SEEK command; seeks are always reported by the controller to succeed, since the `success' only refers to the controller's idea of success - there is no hardware line to tell about the seek end (other than the `track 0' line) . catch SENSEI's that report about a `terminated due to READY changed' status - could happen after a controller reset . converted ``hz / <something>'' divide operations to divisors that are powers of two, so gcc can optimize them into shifts . write/format operations are checked against a write-protected medium now *prior* starting the operation . error reports of `invalid command' and `wrong cylinder' will cause shortcuts in the retrier() now . fixed a bug in the retrier() causing bogus block numbers to be reported . fdformat() does care for errors now Known Bugs: . no attempts have been made (yet) to improve the performance . sometimes, bogus ``seek/recalib failed'' messages are logged; this is still a bug in the driver, but it's not harmful since it's usually caught by the retrier() Reviewed by: Submitted by: Obtained from:
