There's no point in trying to clean up after driver-bugs, so just blow up. Furthermore it's an interface abuse to set no mode but have an fb and aslo to try to set an fb without enough connectors. These two spefici cases of interface abuse have been committed by the fb helper, but that's been fixed meanwhile in commit 7e53f3a4 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Jan 21 10:52:17 2013 +0100 drm/fb-helper: fixup set_config semantics The i915 driver has been shipping since a while with these BUGs with no reports, so should be save. Note that this drops an ugly case where we clear crtc->fb behind the upper levels back and so cause a refcounting mayhem, which Russell Kins spotted while trying to hunt down a drm framebuffer leak.

Running mgag200_driver_unload when the driver init fails early on causes functions like drm_mode_config_cleanup to be called. The problem is, drm_mode_config_cleanup crashes because the corresponding init hasn't happend yet. There really isn't anything to cleanup after mgag200_device_init, so we can just pass the error code upwards. Acked-by:

G200 cards support, at best, 16 colour palleted images for the cursor so we do a conversion in the cursor_set function, and reject cursors with more than 16 colours, or cursors with partial transparency. Xorg falls back gracefully to software cursors in this case. We can't disable/enable the cursor hardware without causing momentary corruption around the cursor. Instead, once the cursor is on we leave it on, and simulate turning the cursor off by moving it offscreen. This works well. Since we can't disable -> update -> enable the cursors, we double buffer cursor icons, then just move the base address that points to the old cursor, to the new. This also works well, but uses an extra page of memory. The cursor buffers are lazily-allocated on first cursor_set. This is to make sure they don't take priority over any framebuffers in case of limited memory. Here is a representation of how the bitmap for the cursor is mapped in G200 memory : Each line of color cursor use 6 Slices of 8 bytes. Slices 0 to 3 are used for the 4bpp bitmap, slice 4 for XOR mask and slice 5 for AND mask. Each line has the following format: // Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 // // S0: P00-01 P02-03 P04-05 P06-07 P08-09 P10-11 P12-13 P14-15 // S1: P16-17 P18-19 P20-21 P22-23 P24-25 P26-27 P28-29 P30-31 // S2: P32-33 P34-35 P36-37 P38-39 P40-41 P42-43 P44-45 P46-47 // S3: P48-49 P50-51 P52-53 P54-55 P56-57 P58-59 P60-61 P62-63 // S4: X63-56 X55-48 X47-40 X39-32 X31-24 X23-16 X15-08 X07-00 // S5: A63-56 A55-48 A47-40 A39-32 A31-24 A23-16 A15-08 A07-00 // // S0 to S5 = Slices 0 to 5 // P00 to P63 = Bitmap - pixels 0 to 63 // X00 to X63 = always 0 - pixels 0 to 63 // A00 to A63 = transparent markers - pixels 0 to 63 // 1 means colour, 0 means transparent Signed-off-by:Mathieu Larouche <mathieu.larouche@matrox.com> Acked-by:

Many of the drivers didn't implement palette/gamma handling, but were forced to provide stubs for the hooks to avoid drm_fb_helper from oopsing. Now that the hooks are optional, we can eliminate all the stubs. Signed-off-by:

Check whether the crtc provides the load_lut callback before calling it. This allows the driver to provide the hook only for those CRTCs that actually have the hardware support for it. Also check whether the driver provided the fb_helper gamma_set/gamma_get hooks. It's a driver bug if it allows non-truecolor fbdev visuals w/o these hooks, but auditing all the drivers is too tedious. So just slap a big WARN_ON() there and bail out before things start to explode. Signed-off-by:

drm_plane_force_disable() will forcibly disable the plane even if user had previously requested the plane to be enabled. This can be used to force planes to be off when restoring the fbdev mode.

Having both modes can be beneficial for video playback cases. If you can match the video framerate exactly, and the audio and video clocks come from the same source, you should be able to avoid dropped/repeated frames without expensive operations such as resampling the audio to match video output rate. Rather than add both variants based on the CEA extension short video descriptors in do_cea_modes(), add only one variant there. Once all the EDID has been fully probed, do a loop over the entire probed mode list, during which we add the other variants for all modes that match CEA modes. This allows us to match modes that didn't come via the CEA short video descriptors. For example one Samsung TV here doesn't have the 640x480-60 mode as a SVD, but instead it's specified via a detailed timing descriptor. Signed-off-by:
