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:

The MCDE driver differentiates only between "te_sync" (for hardware TE0 sync) and software sync (i.e. manually triggered updates) at the moment. However, none of these options work correctly for video mode panels. Therefore, we need to make some changes to make them work correctly: - Select hardware sync coming from the (DSI) formatter. - Keep the FIFO permanently enabled (otherwise MCDE will stop feeding data to the panel). - Skip manual software sync (this is not necessary in video mode). Automatically detect if the connected panel is using video mode and enable the necessary changes in that case. Signed-off-by: -

At the moment, vblank handling is only enabled together with TE synchronization. However, the vblank IRQ is also working with on displays without TE synchronization (e.g. DSI video mode panels). It seems like the vblank IRQ is actually generated by the MCDE hardware for the channel. Therefore, the vblank handling should be working correctly in all the cases and we can enable it unconditionally. Signed-off-by:

Udl's GEM code and the generic SHMEM are almost identical. Replace the former with SHMEM. The dmabuf support in udl is being replaced with generic GEM PRIME functions. The main difference is in the caching flags for mmap pages. By default, SHMEM always sets (uncached) write combining. In udl's memory management code, only imported buffers use write combining. Memory pages of locally created buffer objects are mmap'ed with caching enabled. To keep the optimization, udl provides its own mmap function for GEM objects where it fixes up the mapping flags. v3: - restore udl vmap that enables caching v2: - remove obsolete code in a separate patch Signed-off-by:

In preparation of a switch to SHMEM, udl now allocates its GEM objects via struct drm_driver.gem_create_object. No functional changes are made. For SHMEM GEM objects, udl will require the use of a special mmap function, which we set though the create-object function. Signed-off-by:

The flags field in struct udl_gem controls mapping parameters: cached access for local buffers, write-combined access for imported buffers. We can drop the field and distinguish both cases by testing whether struct drm_gem_object.import_attach is NULL. Signed-off-by:

The implementation of ast_set_vbios_mode() converts a DRM display mode and framebuffer into an adjusted mode and stores information for the video BIOS to several scratch regsiters. Here we split the function into individual functions that do the conversion, set the VBIOS mode information and format information. This makes it compatible with support for primary planes and atomic modesetting. Signed-off-by:

Legacy (non-atomic) page flip support is added to the driver by using the mode_set_base CRTC function, that allows configuring a new framebuffer for display. Since the function requires the primary plane's fb to be set already, this is done prior to calling the function in the page flip helper and reverted if the flip fails. The vblank interrupt handler is also refactored to support passing an event. The PIPE_TE_STATUS bit is also considered to indicate vblank on medfield only, as explained in psb_enable_vblank. It was tested by running weston on both poulsbo and cedartrail. Signed-off-by:
