thorpej 5f0577babc Adapt to the new scsipi_adapter interface. 1998-11-19 21:43:00 +00:00
mrg db3051d720 fix problems in many d_mmap routines:
- 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!

briggs ab9470909c Preliminary support for both serial consoles and kbd/display wscons
consoles for TC alphas.  Based on code from Takuya Koumoto
<takuya-k@is.aist-nara.ac.jp> as well as some parts of Toru Nishimura's
and Matthias Drochner's work on pmax wscons.  This relies on the
NEW_SCC_DRIVER.

briggs ba0625f1f5 vm_offset_t no longer exists. Change to paddr_t, vaddr_t, and psize_t. 1998-10-19 00:32:44 +00:00
thorpej 29d472f53d Garbage-collect the open_target_lu and close_target_lu entry points from
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.

thorpej d6041754c2 Allow the DMA tag to specify a boundary contraint. If the device has a
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

thorpej c59c1eae2a Define ioasic device offsets in terms of standard ioasic "slot" offsets. 1998-05-27 00:18:13 +00:00
thorpej 1ef3ca572e - Additional rearrangement for the sake of running on the DECstation some
day.
- Convert to use bus_dma.
- Fix cleaning up unaligned start address.
- Correctly determine if the device supports Fast SCSI, and adjust the
  minimum sync period accordingly.
- Compute minimum sync period correctly on the 25MHz devices.
- Use GPI2 to determine if we're a 25MHz or 40MHz device.
- Currectly determine SCSI ID and "fast mode enabled" for the built-in
  TCDS on DEC 3000 models, using cached information from the PROM environment.

thorpej 3aa84f9e26 - Make this into a proper attachment (i.e. use asc_tcds) and clean up
the namespace accordingly.
- Set FCLK in the CFG3 register if we have a > 25MHz clock.
- Indicate that we support Fast mode to the back-end if we're told we're
  fast by the TCDS layer.
- Correctly compute the minimum sync period.

thorpej 2d384ae1a1 GPI2 in the CIR register indicates our clock speed: 1 = 25MHz, 0 = 40MHz. 1998-05-26 22:48:01 +00:00
thorpej 57c68363d6 Add support for reading the SCSI ID and "fast mode enabled" from the
PMAZB-AA and PMAZC-AA EEPROM.

thorpej d3ead78027 Several changes to the TurboChannel Dual SCSI driver:
- Fix the autoconfiguration model; the TCDS children don't attach to
  TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
  PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
  TurboChannel driver (i.e. work on DECstations).

drochner 95bdb660ed Simple screen attribute handling for wscons.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

thorpej d19fbe1196 Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore.  Replace it with a real mainbus
attach args structure.

thorpej 49aa171ab9 Add support for chaining DMA windows together, for falling back on
SGMAPs if a direct-mapped window fails.
1998-05-13 21:21:16 +00:00
thorpej 4665241bf8 Simplify the direct-mapped DMA case somewhat by adding a window base
member to the DMA tag, and calling the direct-mapped back-ends directly,
rather than through chipset-specific front-ends which pass the window
base as an additional argument.

thorpej ee83014c4d Initial mostly-working ioasic attachment for the MI 8530 SCC driver. It is
enough to use as a console on my DEC 3000/400 (connected to a VT-520
terminal).

XXX The MI SCC driver needs serious changes to handle platforms which
have muliple SCC attachments (e.g. the Alpha port, which has an ioasic
attachment for TurboChannel systems and a gbus attachment for TurboLaser
systems).

XXX The MI SCC driver also needs changes to deal with the wacky (to put
it mildly) way the chips are wired up on the ioasic (on both TC Alphas
and DECstations).  These are going to come along later.

jonathan d3d99a28c9 Update #ifdef'ed-out changes from pmax :
* Add more #ifdef pmax/#endif, #ifdef alpha/#endif where appropriate.
    Config and heade files need more work (or replacement)
  change TK_NOTYET to HAVE_RCONS
  change commented-out /* && cn_tab.cn_screen */ to && raster_console()
  * Add DDB hooks.
  * Note where Alpha console ignores carrier on consoles.
  * Add pmax-derived console tty-size code inside HAVE_RCONS
  * Fold in gross pmax rcons-input hooks, inside HAVE_RCONS

Untested, but whitespace/ifdef only,  cross-compiles OK,
preprocessing shows no significat differences (famous last words)

thorpej e5e8573d5c Allocate the LANCE DMA area and set it up here. This is still not
optimal (really should be done further down the food chain), but we
can't really do that in a nice way right now, and this is much better
than what we had before (which was to steal memory pages before the
VM system was bootstrapped).

thorpej 0c2efd7025 Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached.  Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.
