vga: fix build when fbdev is a module

2012-04-24T08:50:21+00:00

This fixes the build breakage reported by Stephen in -next when merging the drm-next tree. Signed-off-by: Dave Airlie

efifb: Implement vga_default_device() (v2)

2012-04-24T08:50:18+00:00

EFI doesn't typically make use of the legacy VGA ROM, but it may still be configured to pass that through to a given video device. This may lead to an inaccurate choice of default video device. Add support to efifb to pick out the correct active video device. v2: fix if->ifdef Signed-off-by: Matthew Garrett Acked-by: hpa@zytor.com Cc: matt.fleming@intel.com Signed-off-by: Dave Airlie

efifb: Fix call to wrong unregister function

2011-06-14T07:37:46+00:00

platform_device_unregister() needs to unregister the device, not the driver. Signed-off-by: Wanlong Gao Signed-off-by: Maarten Lankhorst Acked-by: Andy Lutomirski Signed-off-by: Paul Mundt

efifb: Disallow manual bind and unbind

2011-06-02T08:18:07+00:00

Both were buggy: bind would happily scribble over a real graphics device and unbind wouldn't destroy the framebuffer. Hotplugging efifb makes no sense anyway, so just disable it. As an added benefit, we save some runtime memory. Signed-off-by: Andy Lutomirski Signed-off-by: Peter Jones Signed-off-by: Paul Mundt

efifb: Enable write-combining

2011-06-02T08:18:04+00:00

Running fbcon on an uncached framebuffer is remarkably slow. So try to enable write combining in efifb. Without this patch, it takes 5.8 seconds from efifb probe to i915 probe (default options; no plymouth or quiet mode). With this patch, it only takes 1.7 seconds. That means we wasted over 4 seconds just writing to UC memory. Signed-off-by: Andy Lutomirski Signed-off-by: Peter Jones Signed-off-by: Paul Mundt

efifb: fix int to pointer cast warning

efifb: Add override for 11" Macbook Air 3,1

2011-04-06T17:58:10+00:00

The 11" Macbook Air appears to claim that its stride is 1366, when it's actually 2048. Override it. Signed-off-by: Matthew Garrett Signed-off-by: Peter Jones Signed-off-by: Paul Mundt

efifb: Support overriding fields FW tells us with the DMI data.

2011-04-06T17:58:10+00:00

Some machines apparently give us bogus linelength/stride/pitch data, so we need to support letting the DMI table override the supplied data. I bet you can't guess whose machines I'm talking about. Signed-off-by: Peter Jones Signed-off-by: Paul Mundt

efifb: support AMD Radeon HD 6490

2011-03-31T04:49:09+00:00

This patch enables the framebuffer for the AMD Radeon 6490 found in the new MacBook Pro 8,2 generation. The framebuffer's base is located at 0x90010000, the method for obtaining it was found in the same way mentioned in https://patchwork.kernel.org/patch/91704/ Signed-off-by: Davidlohr Bueso Signed-off-by: Jonathan Gonzalez Signed-off-by: Paul Mundt
