842f3472dc - Declare lookup tables etc. const. [1]
- Add a missing "ATI" in one of the device descriptions.
- In machfb_init_engine() adjust a wait_for_fifo() call to the
  actual number of operations.
- As a speed optimization cache setting the foreground and back-
  ground colors.
- I got the meaning of V_DISPLAY_BLANK wrong, it's blank like turn
  off and not blank like turn on and clear the screen. So move
  clearing the screen to machfb_clear() were it hopefully belongs.
- Properly implement V_DISPLAY_BLANK, V_DISPLAY_STAND_BY and
  V_DISPLAY_SUSPEND. This makes blank_saver.ko and green_saver.ko
  work. [1]
- Implement machfb_load_palette() and machfb_save_palette() and
  set the V_ADP_PALETTE flag. This makes fade_saver.ko work. [2]
- Install our 16-color color map only once and with an offset of
  16 as the OBP driver expects white to be at index 0 and black at
  255. This fixes the inversion of the colors back at the boot
  prompt after shutting down FreeBSD. This will also be handy if
  we ever want to implement breaking into OFW. Unfortunately there
  doesn't seem to be a better way to achieve this as e.g. bypassing
  the color map isn't supported by all Mach64 chips.
- Move invalidating the cache variables to machfb_set_mode() and
  set the V_ADP_MODECHANGE flag. This causes machfb_set_mode() to
  be called when the X server shuts down. This hopefully will fix
  the screen corruption happening occasionally when shutting down
  the X server and which is present until switching to another VTY.

- Let creator_bitblt() return ENODEV as it's not implemented (missed
  in sys/dev/fb/creator.c rev. 1.6).
- As a speed optimization inline the creator_ras_wait() etc. helper
  functions and also cache setting the font increment, font width
  and plane mask. [1]

- Change the order of operations in creator_fill_rect(), i.e. write
  y before x and cy before cx. This fixes drawing the top part of
  the border with Elite3D cards when switching from Xorg to a VTY.
- Move setting the chip configuration we use and invalidating the
  cache variables to creator_set_mode() and set the V_ADP_MODECHANGE
  flag. This causes creator_set_mode() to be called when the X server
  shuts down which fixes the screen corruption caused most of the
  time by Xorg not restoring the original configuration present at
  startup.

d89b911644 - In machfb_configure() when probed for the high-level console return
the number of registered adapters instead of determining again whether
  stdout is a supported card (and which might have failed to attach and
  register).
- Fix a bug in the handling of the FBIOSCURSOR IOCTL; the code was meant
  to return ENODEV for all invocations expect when used to disable the
  cursor and not just when used for enabling the cursor.
- In case the adapter is the OFW stdout move its OFW cursor to the start
  of the last line on halt so OFW output doesn't get intermixed with what
  FreeBSD left on the screen.
- Drop variable names in the prototypes of some functions in order to
  match the style of majority of the prototypes in this file.

- Drop creator_set_mode() and move the relevant parts to creator_fill_rect()
  and creator_putc() respectively. This is a bit cleaner than having to
  make sure that creator_set_mode() was called before creator_fill_rect()
  or creator_putc() are used and matches better what Xorg does.

  of the last line on halt so OFW output doesn't get intermixed with what
  FreeBSD left on the screen. With hindsight this is what the faking of a
  hardware cursor which was removed in the last revision really was about,
  i.e. to keep the OFW updated about the current cursor position. The new
  approach however is simpler while producing the same result and doesn't
  cause the first letter of the OFW output to be turned into a blank and
  a newline.
- Add variable names to the prototypes of creator_cursor_*() which were
  added in the last revision and list them alphabetically in order to match
  the style of this file.

0a710885bd Add machfb(4), a driver for ATI Mach64 graphics chips intended for
use with syscons(4) on sparc64. It's based on the respective NetBSD
driver with some additional info (initialisation/hardware cursor)
obtained from the Xorg 'ati' driver and some ideas taken from
creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low-
end graphics chips in PCI-based sun4u machines and are used on-board
in e.g. Blade 100 and a couple of OEM products. Most if not all of
the Sun PGX add-on cards family (descriptions of the PGX32 are
conflicting but most say it's a Rage Pro) are also based on these
chips. Depending on the version of the OBP Mach64 cards destined for
use in i386 machines also work in sun4u machines.
The driver uses pixel mode with hardware acceleration as far as
syscons(4) currently permits on sparc64 so text mode is already
quite fast. The hardware cursor is used for the mouse pointer;
for one because this is a "restriction" induced in syscons(4) on
sparc64 by creator(4) and also because of issues with mapping
the aperture when used as a low-level early during boot. Due to
insufficiencies in the available documentation I didn't manage to
get mode switch work properly (sync problems), yet. So for now
this driver relies on the OBP having initialised a mode (as does
creator(4)). On all of the tested machines is even true when using
a serial console (and also not only when the OBP switched to a
serial console because no keyboard is present). In general however
the states the Mach64 chips are left in by the OBP vary a lot
depending on the version of the OBP. This e.g. includes the aperture
not being mapped in even when used as the console and the OBP just
barfing when asked to map it. The latter is also the reason for the
existence of this native driver in FreeBSD rather than taking an
OFW frambuffer approach.
Xorg is also happy to talk to these chips by mmap'ing them through
this driver. For some hardware configs like on the Blade 100 a fix
for the Xorg sparc64 MD bus code is however needed (added in version
6.8.2_2 of the xorg-server port).
The video driver font loading and saving methods are not implemented,
yet, as syscons(4) needs more work in that area to work viable on
sparc64.
With minor modifications machfb(4) would most likely also work on
powerpc, when #ifdef'ing the OFW and possibly implementing mode
setting probably also on the other archs. The latter is however
not very practible at the moment as it would conflict with vga(4).

ff706bdfcf o creator(4):
- Use register macros instead of magic values in the code. [1]
  - Check the return values of OF_getprop() and other stuff that actually
    can fail.
  - Let the unimplemented video driver methods return ENODEV rather
    than 0 so other code isn't tricked into thinking a certain operation
    was successfull. In case of e.g. the video driver creator_ioctl()
    this caused vidcontrol(1) to return random garbage information.
    Remove the TODO macros in the unimplemented video driver methods
    which did a printf("%s: unimplemented\n", __func__). Under certain
    circumstances these managed to invoke a printf() when a low-level
    console device wasn't attached, yet, causing a Fast Data Access MMU
    Miss. These macros were only really usefull for development anyway.
  - Set the struct video_adapter and struct video_info va_flags and
    vi_flags etc. as appropriate.
  - In creator_configure() don't rely on hitting the node which is the
    chosen console device first when searching the OFW tree for adapters
    compatible with this driver. Instead just check whether the chosen
    console device is a viable target for this driver. Targets that are
    not the console (including additional cards in multi-head configs)
    will be attached through creator_upa_attach(). I think this how the
    code in creator_configure() was actually meant to work.
    Honour the VIO_PROBE_ONLY flag and don't initialise and register the
    console device twice when creator_configure() is called a second time
    during sc_probe_unit().
    Let creator_configure() return the number of the found adapters,
    i.e. 1 in case probing succeeds, as it's expected. The return values
    of video adapter configure functions however currently aren't checked
    so this doesn't make a difference at the moment.
  - In creator_upa_attach() don't rely on probing and attaching the
    adapter which is the console first, in case there are multiple
    adpaters and one of them is the console this could lead into using
    the video adapter unit 0 twice.
  - Make the check for DACs with inverted cursor control a bit more
    precise and actually honour that information when turning the cursor
    on or off. Add a helper function creator_cursor_enable() for this
    in order to keep code duplication low. [1]
  - Don't bother with faking a hardware cursor in case a device is the
    console. Apparently this was meant to start kernel output right after
    where the firmware left. In general this isn't worth the fuzz and
    also had no real effect as creator_set_mode() did clear the screen
    in any case, not just in case a device was not the console.
  - Implement creator_fill_rect() and use it to actually blank the
    display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
    moving blanking the display out of creator_set_mode(). Use it also
    to implement creator_set_border() so the border can be re-drawn
    when switching to a VTY from X, exiting X, etc. (which leaves us
    with a black border most of the time).
  - Implement the video driver creator_ioctl(), moving the implementation
    of the IOCTL interface from the fbN CDEV version of creator_ioctl()
    into the video driver version and use the latter to implement the
    former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
    This gives programs like vidcontrol(1) which use the video driver
    creator_ioctl() a chance of working.
    Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
    Xorg uses to in order to inform the OS that it's taking over the
    cursor. In creator_putm() check whether the cursor is enabled and
    (re-)install it if necessary, moving installing the cursor out of
    creator_init() and into a helper function creator_cursor_install().
    This fixes the missing mouse pointer when switching to a VTY from X,
    exiting X, etc.
  - Some clean-up (remove unused/useless code, etc.).

o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
  - Attach syscons(4) as an own pseudo-device on the nexus rather than
    directly in creator_upa_attach(), similiar to attaching syscons(4)
    as a pseudo-device on isa(4) on other archs. This makes it a whole
    lot easier to do the right thing in multi-head configs, especially
    with different types of graphics adapters. [2]
  - Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
    box. [2]

because it was mostly irrelevant - except for the silly BIOS_PADDRTOVADDR

* Make syscons properly inherit the bios capslock/shiftlock/etc state like
  i386 does.  Note that we cannot inherit the bios key repeat rate because
  that requires a bios call (which is impossible for us).
* Give syscons the ability to beep on amd64.  Oops.

6e7272f69d - Use an ihandle_t to store the stdout instance handle instead of a

  or less cosmetic.

  for firmware output (and should not be blanked on initialization).
  Since r1.2 of dev/fb/creator.c, this consisted comparing a handle of
  an instance of a package with a handle of the package itself.
  Use the test from r1.1, which utilizes OF_instance_to_package().

bf920dafa4 Add a driver for creator upa frame buffers found in many sparc64 machines.
These are fixed resolution and operate only in pixel mode so they present
a challenge to syscons (square peg, round hole, etc, etc).  The driver
provides a video driver interface for syscons and a separate character
device for X to mmap.  Wherever possible the creator's accelarated graphics
functions are used so text mode is very fast.

- Use this to represent physical addresses in the MI vm system and in the

- Fix printf formats to handle physical addresses >4G in the i386 memory

Note that this is a name change only; vm_paddr_t is still the same as

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.
