psbfb_probe performs an evaluation of the required size from the stolen GTT memory, but gets it wrong in two distinct ways: - The resulting size must be page-size-aligned; - The size to allocate is derived from the surface dimensions, not the fb dimensions. When two connectors are connected with different modes, the smallest will be stored in the fb dimensions, but the size that needs to be allocated must match the largest (surface) dimensions. This is what is used in the actual allocation code. Fix this by correcting the evaluation to conform to the two points above. It allows correctly switching to 16bpp when one connector is e.g. 1920x1080 and the other is 1024x768. Signed-off-by:

In case of tiled displays, if we hotplug just one connector, fbcon currently just selects the preferred mode and if it is tiled mode then that becomes a problem if rest of the tiles are not present. So in the fbdev driver on hotplug when we probe the client modeset, if we dont find all the connectors for all tiles, then on a connector with one tile, just fallback to the first available non tiled mode to display over a single connector. On the hotplug of the consecutive tiled connectors, if the tiled mode no longer exists because of fbcon size limitation, then return no modes for consecutive tiles but retain the non tiled mode on the 0th tile. Use the same logic in case of connected boot case as well. This has been tested with Dell UP328K tiled monitor. v2: * Set the modes on consecutive hotplugged tiles to no mode if tiled mode is pruned (Dave) v1: * Just handle the 1st connector hotplug case * v1 Reviewed-by: Dave Airlie <airlied@redhat.com> Suggested-by:

The DSI initialization sequence incorrectly assumes that the mode_set() function of the DRM bridge is always called when (re-)enabling the display. This is not necessarily the case. Keeping the device idle in the framebuffer console for a while results in the display being turned off using the disable() function. However, as soon as any key is pressed only (pre_)enable() are called. mode_set() is skipped because the mode has not been changed. In this case, the DSI HS/LP clocks are never turned back on, preventing the display from working. Fix this by moving a part of the initialization sequence from mode_set() to pre_enable(). Keep most of the video mode setup in mode_set() since most of the registers are only dependent on the mode that is set for the panel - there is no need to write them again each time we re-enable the display.

Using a (single) DSI display with MCDE currently results in two "connected" connectors: Connector: DSI-1 id : 34 encoder id : 0 conn : connected size : 0x0 (mm) count_modes : 0 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Connector: DSI-2 id : 35 encoder id : 33 conn : connected size : 53x89 (mm) count_modes : 1 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Mode: "480x800" 480x800 60 Although both show up as connected, the first one does not have any size and no available modes. This confuses userspace tools (e.g. kmscube) who look for available modes for the first connector. The reason for the duplicated connector is that mcde_dsi.c and the DRM panel bridge helper both set up a DSI connector, with more or less the same code. The connector set up by the DRM panel bridge is the one that is correctly set up in the example above. Therefore we can just remove the connector setup from mcde_dsi.c and let the DRM core handle all the hard work. Signed-off-by: -

The initialization order for DSI video mode is important - if we enable the video stream generator (VSG) before the MCDE DSI formatter starts sending pixel data, it will immediately run into an error and disable itself again. Avoid this problem by delaying the activation of the VSG until the MCDE DSI formatter is properly set up and running (i.e. when mcde_dsi_bridge_enable() is called). Signed-off-by:
