As we keep an rbtree of available holes sorted by their size, we can very easily determine if there is any hole large enough that might satisfy the allocation request. This helps when dealing with a highly fragmented address space and a request for a search by address. To cache the largest size, we convert into the cached rbtree variant which tracks the leftmost node for us. However, currently we sorted into ascending size order so the leftmost node is the smallest, and so to make it the largest hole we need to invert our sorting. Signed-off-by:

Use new return type vm_fault_t for fault and huge_fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Commit 1c8f4220 ("mm: change return type to vm_fault_t") Previously vm_insert_page() returns err which driver mapped into VM_FAULT_* type. The new function vmf_ insert_page() will replace this inefficiency by returning VM_FAULT_* type. Signed-off-by:

There's an ongoing effort to remove VLAs[1] from the kernel to eventually turn on -Wvla. The vla in reg_write_range is based on the length of data passed. The one use of a non-constant size for this range is bounded by the size buffer passed to hdmi_infoframe_pack which is a fixed size. Switch to this upper bound.

Commit bc61c975 ("drm/gma500: Move GEM BO to drm_framebuffer") moved the gtt_range structure, from being in psb_framebuffer and embedding the GEM object, to being placed in the drm_framebuffer with the gtt_range being derived from the GEM object. The conversion missed out the Medfield subdriver, which was not being built in the default drm-misc config. Do the trivial fixup here. Signed-off-by:

Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those. Signed-off-by:

The backlight 1st update was in the otm8009a_prepare() function for a bad reason: backlight was not working in video mode and the otm8009a_prepare() is in command mode for the init sequence. As the backlight is now fixed (no low-power mode), it is good to put it back in the otm8009a_enable() function, avoiding also image glitches visible on some "slow" devices. Signed-off-by:

Backlight updates was not working anymore since the good implementation of the DSI low-power mode in the DSI host driver. After a longer analysis, the backlight updates in DSI video mode require the DSI high- speed mode. Note: it is important to keep the DSI low-power mode for the rest of the driver as init sequence, sleep in/out... DSI commands work in low-power mode. Signed-off-by:

Add device_link from panel device (supplier) to DRM device (consumer) when drm_panel_attach() is called. This patch should protect the master DRM driver if an attached panel driver unbinds while it is in use. The device_link should make sure the DRM device is unbound before the panel driver becomes unavailable. The device_link is removed when drm_panel_detach() is called. The drm_panel_detach() should be called by the consumer DRM driver, not the panel driver, otherwise both drivers are racing to delete the same link. Signed-off-by:

Remove all drm_panel_detach() calls from all panel drivers and update the kerneldoc for drm_panel_detach(). Setting the connector and drm to NULL when the DRM panel device is going away hardly serves any purpose. Usually the whole memory structure is freed right after the remove call. However, calling the detach function from the master DRM device, and setting the connector pointer to NULL, has the logic of marking the panel again as available for another DRM master to attach. The usual situation would be the same DRM master device binding again. Signed-off-by:

Added encoding of drm content_type property from drm_connector_state within AVI infoframe in order to properly handle external HDMI TV content-type setting. This requires also manipulationg ITC bit, as stated in HDMI spec. v2: * Moved helper function which attaches content type property to the drm core, as was suggested. Removed redundant connector state initialization. v3: * Removed caps in drm_content_type_enum_list. After some discussion it turned out that HDMI Spec 1.4 was wrongly assuming that IT Content(itc) bit doesn't affect Content type states, however itc bit needs to be manupulated as well. In order to not expose additional property for itc, for sake of simplicity it was decided to bind those together in same "content type" property. v4: * Added it_content checking in intel_digital_connector_atomic_check. Fixed documentation for new content type enum. v5: * Moved patch revision's description to commit messages. v6: * Minor naming fix for the content type enumeration string. v7: * Fix parameter name for documentation and parameter alignment in order not to get warning. Added Content Type description to new HDMI connector properties section. v8: * Thrown away unneeded numbers from HDMI content-type property description. Switch to strings desription instead of plain definitions. v9: * Moved away hdmi specific content-type enum from drm_connector_state. Content type property should probably not be bound to any specific connector interface in drm_connector_state. Same probably should be done to hdmi_picture_aspect_ration enum which is also contained in drm_connector_state. Added special helper function to get derive hdmi specific relevant infoframe fields. v10: * Added usage description to HDMI properties kernel doc. v11: * Created centralized function for filling HDMI AVI infoframe, based on correspondent DRM property value.

The vc4 HVS uses an internal RGB888 representation of the frames, and will by default expand formats using a lower depth using zeros. This causes an issue when we try to use other compositing software such as pixman that fill the missing bits by repeating the higher significant bits. As such, we can't check the display output in a reliable way by doing a software composition and an hardware one and compare both. To prevent this, force the same behaviour so that we can do such things. Signed-off-by:
