f2437436f6 sparc complains "cast to pointer from integer of different size"; cast the 
int to (void *)(long).

90c7459808 If the bus glue provides an ioctl handler, don't return before we have a 
chance to perform generic handling in the WSDISPLAYIO_SMODE case.

ok macallan

d994f000f0 Add clear-screen and cursor-row properties to allow genfb to persist 
screen state from the MD console driver.

e04f5ff1b4 Provide callbacks so MD code can explicitly prevent genfb from matching; 
works around vga/genfb deathmatches.

ec798a6e6c Introduce genfb_ops genfb_borrow callback to allow the bus frontend to 
lend mappings to drm.

a71612a2f8 Provide a stub genfb_cnattach for md code to call to give a hint to the 
bus driver's match function to return a higher confidence (so it can
beat out vga(4), for example). genfb needs-flag so md code can determine
if the genfb driver is present.

7bca1efe39 Do not attach genfb when the frame buffer is not flagged as being console 
(e.g. when a serial console is used).
Approved by macallan.

f59f835fa4 don't panic if we're not finding all the properties we need. Just complain 
quietly and return.

d2525db73d Clear the screen during initialization so that the first messages are not 
printed over "unknown garbage" (e.g. the Mac OS desktop).  Agreed with

90ad1537c2 Properly initialize the palette registers by calling the colormap callback 
on all of them.  A typo made it only initialize half of them.  OK'ed by

84b4b152a9 fix typo - fbsize is /height/ * stride. Doh. 2007-08-05 03:23:02 +00:00

42284ad7c0 add shadow fb support 
now genfb is actually usable even on slow PCI framebuffers. Yay Jared :)

aa2949fa77 add a callback to change the colour map 
so now X with wsfb on top of genfb should look right

66d86be89a - move all memory mapping into the bus frontend 
- get rid of macppc-isms like *_mmap() returning physical addresses

4cf8aa1d7f add genfb, a generic framebuffer console driver that's configured via 
device properties - all it needs is width and height in pixels, stride in
bytes, depth in bits and the framebuffer address.
Features:
- unaccelerated fb console with colours and virtual consoles
- split into console handling and bus frontend
- so far there is only a PCI bus frontend which allows to mmap BARs belonging
  to the graphics controller, others should be easy to add.

TODO:
- find an opaque way to change the palette ( probably pass a function
  pointer as property ) since this would need to call some firmware interface
  which is pretty much always MD
- find a clean way to mmap the framebuffer, just returning the physical
  address works on macppc but not on other architectures. Problem is, that
  we cannot rely on the address being a bus address - on macppc it is,
  but for instance on sparc64 it's not.
