offb: Fix bug in calculating requested vram size

2012-01-12T19:40:01+00:00

commit c055fe0797b7bd8f6f21a13598a55a16d5c13ae7 upstream.

We used to try to request 8 times more vram than needed, which would
fail if the card has a too small BAR (observed with qemu & kvm).

offb: Fix setting of the pseudo-palette for >8bpp

2012-01-12T19:40:01+00:00

commit 1bb0b7d21584b3f878e2bc880db62351ddee5185 upstream.

When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
and doesn't touch the color map even if it has a corresponding access method
for the real hardware.

Thus it needs to set the pseudo-palette with all 3 components of the color,
like other truecolor framebuffers, not with copies of the color index like
a directcolor framebuffer would do.

This went unnoticed for a long time because it's pretty hard to get offb
to kick in with anything but 8bpp (old BootX under MacOS will do that and
qemu does it).

offb: Add support for framebuffer handoff to offb.

2010-03-15T15:49:42+00:00

commit ceae8cbe94f3127253110e2d01b9334069e93177 upstream.

This allows offb to be used for initial framebuffer,
and a kms driver to take over later in the boot sequence.

offb: use framebuffer_alloc() to allocate fb_info struct

2009-06-17T02:47:58+00:00

Use the framebuffer_alloc() function to allocate the fb_info structure so
the structure is correctly initialized after allocation.

fbdev: Teaches offb about palette on radeon r5xx/r6xx

2008-07-22T00:39:36+00:00

The offb driver already has a collection of hacks to be able to set
the palette on various chips. This adds support for r5xx/r6xx radeons.

This is needed as offb is the only console solution on these currently
and the firmware in some cases sets a really bad color palette. This
fixes using some Radeon X16xx on the Powerstation for example.

[POWERPC] Rename device_is_compatible to of_device_is_compatible

2007-05-07T10:31:14+00:00

for consistency with other Open Firmware interfaces (and Sparc).

This is just a straight replacement.

This leaves the compatibility define in place.
