Intel

• Enabling some modifiers can lead to hitting bandwidth limitations (not being able to light up a CRTC).
• With YUV buffers, planes can only have a position with even coordinates (or odd?).

AMD

• There's no real cursor plane, instead the hardware draws it on the top-most plane (overlay if enabled, otherwise primary). Thus the cursor composition properties (scaling, rotation, blend mode, etc) must match the underlying plane's. An RGB cursor buffer can't be used if the underlying plane uses a YUV format.
• 90-degree and 270-degree rotations are not supported for linear buffers. Tiled buffers are required.
• The primary plane needs to be enabled to allow any other plane to be enabled.

What does a mailing list need to do to reflect a message?

Method 1

Keep the original From header. Add a Sender header field with the list's address. Broadcast message with MAIL FROM set to the list's address.
