o fix return type of sio_pccard_detach
o don't free softc in deatch, since that is done by newbus
o disconnect interrupt we used to have. Add cookie to com so that we can
tear down the interrupt on unload
o Set gone earlier, but likely doesn't matter
This makes sio pccards work again. Cards that are active when ejects may
not work (but they might, softc goes away quickly).
These changes are unreviewed by bde. I'll make any style changes he wants.
returns "0" on failure, which is indistinguishable from (say) irq 0. This
should stop a couple of stray messages that turn up.
Also, if a BUS_SETUP_INTR() fails with INTR_TYPE_FAST, try falling back to
a normal interrupt. This might help pccard folks with a shared slot
interrupt. This whole thing needs to be revisited.
problem.
o Create new timeout routine so we don't detach the card inside a ISR
but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
if_down. if_detach destroys the device, while if_down just marks it
down. In this incarnation of the pccard things, we map the disable
the slot action to detach the driver, which removes the driver from the
device tree. When that is done, a panic would soon follow as the
ifconfig tried to down the device.
Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called. sio's softc used
to be statically allocated, so you could check sc->gone, but that is
now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.
Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)
Remove EXTRA_SIO/NSIOTOT and make it fully dynamic (from dev/sio/sio.c)
Make sio work for pccard here - pccardd doesn't activate interrupts
until after prove has succeeded.
Mark the initial reset of likely sio ports as broken as it depended on
config supplying a list of locations to probe, devices are now proved
standalone.
Optimize a bit of COM_NOAST4() logic.
Use bus_get_resource_start() etc rather than using isa-centric calls.
Reactivate the IIR_TXRDYBUG test, I've got a card here with it.
Try to be a bit smarter about activating interrupts (ie: don't panic
if polled)
Fix some style bugs that have crept in over time (there are still more).

This has not been reviewed by bde, so I'm committing to resolve any

I've had four reports of this working for them. I've been able to

Add a slightly different safetybelt under nostop for tty drivers.
Add some missing FreeBSD tags

d_stop moved to struct tty.
d_reset already unused.
d_devtotty linkage now provided by dev_t->si_tty.
These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.
The changes in this patch consist of:

remove devtotty functions
rename ttpoll to ttypoll

new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.
This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.

Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().
- Split syscons source code into manageable chunks and reorganize
some of complicated functions.
- Many static variables are moved to the softc structure.
- Added a new key function, PREV. When this key is pressed, the vty
immediately before the current vty will become foreground. Analogue
to PREV, which is usually assigned to the PrntScrn key.

- Modified the kernel console input function sccngetc() so that it
handles function keys properly.
- Reorganized the screen update routine.
- VT switching code is reorganized. It now should be slightly more
robust than before.
- Added the DEVICE_RESUME function so that syscons no longer hooks the
APM resume event directly.
- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
SC_NO_HISTORY and SC_NO_SYSMOUSE.
Various parts of syscons can be omitted so that the kernel size is
reduced.
SC_PIXEL_MODE
Made the VESA 800x600 mode an option, rather than a standard part of
syscons.
SC_DISABLE_DDBKEY
Disables the `debug' key combination.
SC_ALT_MOUSE_IMAGE
Inverse the character cell at the mouse cursor position in the text
console, rather than drawing an arrow on the screen.

SC_DFLT_FONT
makeoptions "SC_DFLT_FONT=_font_name_"
Include the named font as the default font of syscons. 16-line,
14-line and 8-line font data will be compiled in. This option replaces
the existing STD8X16FONT option, which loads 16-line font data only.
- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.
- The video driver provides a set of ioctl commands to manipulate the

Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60. These
modes are mot always supported by the video card.

- The header file machine/console.h is reorganized; its contents is now
split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
(another new file). machine/console.h is still maintained for
compatibility reasons.
- Kernel console selection/installation routines are fixed and
slightly rebumped so that it should now be possible to switch between
the interanl kernel console (sc or vt) and a remote kernel console
(sio) again, as it was in 2.x, 3.0 and 3.1.
- Screen savers and splash screen decoders
Because of the header file reorganization described above, screen
savers and splash screen decoders are slightly modified. After this
update, /sys/modules/syscons/saver.h is no longer necessary and is
removed.
Reformat and initialize correctly all "struct cdevsw".
Initialize the d_maj and d_bmaj fields.
The d_reset field was not removed, although it is never used.
I used a program to do most of this, so all the files now use the

Vinum and i4b not modified, patches emailed to respective authors.
although this is pretty trivial. devclass_get_softc() is a tad more
expensive than the old com_addr() implementation. If Bruce is really
worried about the cost of this, it could always be changed so that the
softc pointer is stored in a local array again.
I'm not too happy about the result either, but at least it has less
chance of backfiring.
This particular feature could be called "a mess" without offending
anybody.
Virtualize bdevsw[] from cdevsw. bdevsw() is now an (inline)
function.
Join CDEV_MODULE and BDEV_MODULE to DEV_MODULE (please pay attention
to the order of the cmaj/bmaj arguments!)
Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE
(ditto!)
(Next step will be to convert all bdev dev_t's to cdev dev_t's
before they get to do any damage^H^H^H^H^H^Hwork in the kernel.)
Mark the GDB port in the config file with flags 0x80. Currently
only the sio driver checks these flags and sets up a GDB port,
but adding similar code to other serial drivers would be easy.
For backward compatibility, if an sio port is marked as the console
and no port is marked as the gdb port, the GDB port will be mapped
to the console port. This hack should go away at some point.
