console setup and driver attach-time.
* Dont wire potential console lines as CLOCAL; use softcar.
* #ifdef tests on #ifdef NRASTERCONSOLE, not HAVE_RCONS.
* use dc_coldparam() in dc_tty_init(), dc_kbd_init().
* use dc_tty_init() to set line for serial console in dc_consinit()
* only call dc_mouse_init() if the console major-number is RCONSDEV.
- returned EOPNOTSUPP rather than -1.
- no check for negative offset.
many of these fix potential security problems in these drivers.
XXX XXX XXX
the d_mmap cdev routine should be changed to have a prototype like:
paddr_t (*d_mmap) __P((dev_t, off_t, int));
by someone!
Use scc_tty_init() in scc_consinit(). Declare scc_consinit() in sccvar.h.
* Remove last vestige of special-case console handling in sccparam() code.
* Call scc_consinit() from findcons scc_serial() console-setup.
Dont PROM for scc serial console at all.
attempt results in the up and down arrows not repeating in the X server.
The keyboard division table is modified to place the Right-Shift keycode
into division 6 along with the Left-Shift and Control. A corresponding
change to the X server lk201 keyboard handler is also required.
This got lost when disk geometry processing was updated.
Also move the CDROM check from rzread() to rzwrite() - it doesn't make
much sense to report a read-only filesystem error when trying to read a
CDROM.
struct scsipi_adapter; they were not used.
Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be
used to issue ioctl commands to the host adapters.
Inspired by PR #6090, from Matt Jacob.
initialized yet. Use the base variable, and also use the symbolic symbols
to acdess the registers. Also, the console max_rows is based on the
display height, not the width.
controllers (including SCSI id 7 on the 2100/3100).
- On the pmax (2100,3100) set the host SCSI id to 6.
- Move disk and tape config for the second ASC controller from the GENERIC
config file to scsi.pmax so all configurations can use the second
controller.
* dec_5100.c: sysconf, interrupt, and motherboard (drain writebuffer)
support for 5100.
* support for hardware kludge in 5100: sii DMA buffer is hardware
padded to alternate 32-bit words, not alternating 16-bit halfwords.
* 5100 has no framebuffer, console is wired to serial port 0.
With ibus support, boots as far as exec'ing init, and hangs.
as pmax/dev/findcons.c:
* Follow the same logic: look for the device the PROM is using.
* If it's a framebuffer and we don't have a driver for it, try other
* framebuffers in PROM search order.
* If no match found, warn user and fall over to serial console.
* if no serial console found, go back to PROM.
Rework tc/scc.c attach routine to give cleaner initialization semantics.
Prune out old 'braindamage' code.
* Do rcons output properly, using cn_tab->cn_dev which points
at rcons cdevsw entrypoints.
* The pmadx console code was using keyboard (serial) device
(major,minor) for raster consoles with special code in the keyboard
drivers to catch output intended for consoles, pull it off the device
queue, and print them via cnputc().
Ifdef out RCONS_BRAINDAMAGE.
* Other minor cleanup to pmax scc driver.
also calls biowait().
Some drives seek to modepage on every modepage geometry-sense in rzready()
cache dev_t of last readied device in rzdump() to elide rzready() calls.
2x speedup of dumps on rz25 and 20x-30x speedup on some IBM OEM 4gig drives.
