rin | Add genfb(4) driver for mac68k grfbus.
1, 2, 4, 8, 15, and 32 color-depths are supported.
ANSI colors on console are functional for depth >= 4.
Graphic applications based on wsfb API should work, provided
they can correctly handle fbi_fboffset and your color depth.
wsfb driver of Xorg 1.20 and mlterm-fb (framebuffer version of
x11/mlterm) work fine for depth == 1 || depth >= 8.
For depth == 8 (256 colors), graphic applications require
colormap callback, which is currently supported for some
internal graphic adapters, and only Civic (found on Quadra
AV series) was tested. Register definition and its usage are
taken from Linux. You can easily support other adapters if
Linux supports that.
Have fun, and any problem reports are welcomed!

Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

jmmv | Pack all global video-related variables into a structure for clarity.
A comment said that they weren't in a struct for speed reasons but...
this should not affect performance because these variables are mostly
used to set other variables (hence they are read few times).
|
| 1.55 |
| 29-Aug-2007 |
jmmv | Move the definition of multiple video-related variables into a new
header file (machine/video.h) so that we can kill all the "manual"
externs spread around the code (which were inconsistent among them).
|
| 1.54 |
| 29-Aug-2007 |
jmmv | Split the global videosize variable into videowidth and videoheight:
makes the code clearer and avoids multiple parts of it having to know
how videosize was encoded.

Unmap the valkyrie register space when we're finished with it in
the match function. It's not like we can save that state for later,
and we don't use it anyway.
|
| 1.46 |
| 04-Dec-2000 |
scottr | Fix PR 11000: The esp driver needs two longwords in DAFB register space to
implement pseudo-DMA transfers with the SCSI controller. This caused our
match to fail when we couldn't map the entire DAFB register/control space
for our own use. Instead, we map only (about) what we will need in two
separate regions.
As a consequence we no longer do Turbo SCSI configuration here; indeed, it
may have caused us trouble later on if we actually changed the values
stored in those registers in the esp driver.

The Quadra 605 and LC 47x apparently share the same logic board,

|

| 28-Apr-1999 |
scottr | From Ken'ichi Ishizaka: correct the calculation of the frame buffer
offset by masking off garbage bits in the DAFB v7. This has been
tested at all resolutions and common color depths on the LC47x.

scottr | The Performa/LC 58x have a Valkyrie, not the DAFB.
|

| 12-Aug-1998 |
scottr | New and improved console framebuffer initialization and autoconfig. This
resolves a great many issues, including Performa 58x interrupt handling
and offset displays on some models.
Programs that depend on the old (pre-NetBSD 1.1) grf interface may break.
That's actually a separate issue uncovered by this code, not caused by it.
|

removed from the kernel.

scottr | Store the PA of the framebuffer in the softc. This eliminates the need
for the sc_phys callback; we can just store the PA in the grfbus attach
args, rather than a function pointer, which simplifies the code nicely.

scottr | The monitor sense code we have is not reliable on DAFB-based machines with
certain 17" monitors. Change from Michael R. Zucca, PR 4988.
XXX - This can cause problems on system with the DAFB chip which currently
use only a NuBus-based video adapter. In particular, grf devices may not be
attached properly in this case. This unfortunate situation is less annoying
than not having a reasonable console, however. A reasonable, reliable
monitor sense algorithm for the DAFB would resolve the problem.

might be disabled, and thanks to Henry Hotz (h.b.hotz@jpl.nasa.gov) for

| 03-Aug-1997 |
scottr | Overhaul grf drivers to correct recent problems with X and dt
(address error faults), as well as other reported problems:
- Simplify grfmv_phys() to work like grfiv_phys(), and eliminate the
second argument to both, as we don't use it anyway.
- Handle fbbase and fboff consistently throughout. Closes PR 3862.
- Eliminate grfaddr() by pulling it into grfmmap(), which is the
only place it was used, previously.
- grfmap() now gets the physical address of the framebuffer from
the appropriate driver, rather than try to compute it by itself.
Be careful with aligning the base to a page address and increase
the length of the mapped region appropriately. Closes PR 2867.

briggs | - Support DAFB machines mo' better. Actually detect if a monitor is
present and initialize a few things. No color support, yet.
- Properly disable interrupts for DAFB.
- Rearrange for better nubus display card interrupt support. Only register
an interrupt if we know how to clear it.
- Complain if we don't know about a given display card and can not install
an interrupt handler.
- Change MYSTERY stuff to cb264--still need to get the DrSW so we can
actually call the routine to clear an interrupt from this card.

scottr | branches: 1.16.6;
Convert all foo_match() functions to use a `struct cfdata *' for their
second argument. The NuBus autoconfig code had to be reorganized as a
result of this, and looks much more like a directly-attached bus now.
These changes eliminate __BROKEN_INDIRECT_CONFIG.

scottr | Add a way to tell grf_establish() that internal video doesn't actually
occupy a slot. This is necessary so that GRFIOCMAP can find the correct
physical address of the framebuffer. Fixes P550, some LC models, and
perhaps the PB520.

scottr | branches: 1.12.4;
New grf attachment code, mostly by Jason Thorpe with some cleanup by me.
This will allow dt and X to work with a generic kernel, rather than
compiling different kernels that attach grf0 to a NuBus adapter or
internal video.

briggs | Prototype for -Wall -Wstrict-prototypes -Wmissing-prototypes -Wno-uninitialized
Also change the device probing scheme to use something a bit more rational.
A current side-effect is that nubus cards are double-mapped. I expect
to fix that shortly.
Also change splclock() to block everything but serial hardware interrupts.

Add byte-swap and stride options to bus_space. Allocate as normal, then
call mac68k_bus_space_handle_swapped() or mac68k_bus_space_handle_set_stride().
Stride is untested. Swapped code works for SMC ethernet.
Add bus_space_*_stream_N functions to bus_space.
Add a DIAGNOSTIC panic if (count-using) bus_space macros are called with
a count of zero. Some drivers do this accidentally and some bus_space
implementations will fail if count is passed as zero (they are set up in
a do-{}-while structure).
There were some bogus assumptions about bus_space_handle_t and some
function calls that didn't match prototypes--fix those here, too.
