| | | | | | | | | | | defined, your really getting 32. Also warn about how you can't have more than 256 pty's when your using DEVFS (non DEVFS can use more, just the makedev script doesn't know how to make >256). it also doesn't allocate more memory than needed in this case. Make sure that the signal passed in TIOCSIG isn't 0 as it might cause a panic. I personally haven't seen this happen, but after a similar bug in syscons crashed my machine, I'm acutely aware of this one. :)

* Pass 3 of the great devsw changesjulian1995-12-081-42/+63
| | | | | | | | | | | | | | | | | | | | | | | 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.. :)

| | | | | | | | | | | | | | | | | | | | | | | | 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)
* Moved prototypes for devswitch functions from conf.c and driver sourcesbde1995-11-041-3/+1

* Obtained from: partly from ancient patches of mine via 1.1.5bde1995-07-311-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce TS_CONNECTED and TS_ZOMBIE states. TS_CONNECTED is set while a connection is established. It is set while (TS_CARR_ON or CLOCAL is set) and TS_ZOMBIE is clear. TS_ZOMBIE is set for on to off transitions of TS_CARR_ON that occur when CLOCAL is clear and is cleared for off to on transitions of CLOCAL. I/o can only occur while TS_CONNECTED is set. TS_ZOMBIE prevents further i/o. Split the input-event sleep address TSA_CARR_ON(tp) into TSA_CARR_ON(tp) and TSA_HUP_OR_INPUT(tp). The former address is now used only for off to on carrier transitions and equivalent CLOCAL transitions. The latter is used for all input events, all carrier transitions and certain CLOCAL transitions. There are some harmless extra wakeups for rare connection- related events. Previously there were too many extra wakeups for non-rare input events. Drivers now call l_modem() instead of setting TS_CARR_ON directly to handle even the initial off to on transition of carrier. They should always have done this. l_modem() now handles TS_CONNECTED and TS_ZOMBIE as well as TS_CARR_ON. gnu/isdn/iitty.c: Set TS_CONNECTED for first open ourself to go with bogusly setting CLOCAL. i386/isa/syscons.c, i386/isa/pcvt/pcvt_drv.c: We fake carrier, so don't also fake CLOCAL. kern/tty.c: Testing TS_CONNECTED instead of TS_CARR_ON fixes TIOCCONS forgetting to test CLOCAL. TS_ISOPEN was tested instead, but that broke when we disabled the clearing of TS_ISOPEN for certain transitions of CLOCAL. Testing TS_CONNECTED fixes ttyselect() returning false success for output to devices in state !TS_CARR_ON && !CLOCAL. Optimize the other selwakeup() call (this is not related to the other changes). kern/tty_pty.c: ptcopen() can be declared in traditional C now that dev_t isn't short.
* Obtained from: partly from ancient patches of mine via 1.1.5bde1995-07-221-9/+9
| | | | | Give names to the magic tty i/o sleep addresses and use them. This makes it easier to remember what the addresses are for and to keep them unique.
* Move the inline code for waking up writers to a new functionbde1995-07-221-8/+2
| | | | | | | | | | | ttwwakeup(). The conditions for doing the wakeup will soon become more complicated and I don't want them duplicated in all drivers. It's probably not worth making ttwwakeup() a macro or an inline function. The cost of the function call is relatively small when there is a process to wake up. There is usually a process to wake up for large writes and the system call overhead dwarfs the function call overhead for small writes.
* Obtained from: partly from ancient patches by ache and me via 1.1.5bde1995-07-211-9/+8
| | | | | Nuke `symbolic sleep message strings'. Use unique literal messages so that `ps l' shows unambiguously where processes are sleeping.
* Obtained from: partly from an ancient patch of mine via 1.1.5bde1995-07-211-3/+1
| | | | | | | | | | | | | | | Temporarily nuke TS_WOPEN. It was only used for the obscure MDMBUF flow control option in the kernel and for informational purposes in `pstat -t'. The latter worked properly only for ptys. In general there may be multiple processes sleeping in open() and multiple processes that successfully opened the tty by opening it in O_NONBLOCK mode or during a window when CLOCAL was set. tty.c doesn't have enough information to maintain the flag but always cleared it in ttyopen(). TS_WOPEN should be restored someday just so that `pstat -t' can display it (MDMBUF is already fixed). Fixing it requires counting of processes sleeping in open() in too many serial drivers.
